| [in vitro activity of penicillin g and amoxicillin against 14 strains of streptococcus milleri]. | the mic/mbc of penicillin g and amoxicillin were studied for 14 strains of streptococcus milleri from varied specimens of hospitalized patients by broth dilution method. the mic of penicillin g are between 0.015 and 0.12 mg/l, mic of amoxicillin between 0.015 and 0.5 mg/l. the mbc of penicillin g are between 0.015 and 0.12 mg/l, mbc of amoxicillin between 0.12 and 0.5 mg/l. mbc/mic of penicillin g are between 1 and 8. mbc/mic of amoxicillin are between 1 and 16. the bactericidal effect was studi ... | 1988 | 3054739 |
| streptococcus anginosus ("streptococcus milleri"): the unrecognized pathogen. | "streptococcus milleri" is an unofficial name that has been applied to a group of streptococci which, although basically similar, show various hemolytic, serological, and physiological characteristics. the species name streptococcus anginosus has recently been recognized as the approved name for these organisms. streptococci known as "s. milleri" have been implicated as etiologic agents in a variety of serious purulent infections, but because of their heterogeneous characteristics, these organis ... | 1988 | 3060239 |
| clinically significant streptococcus anginosus (streptococcus milleri) infections: a review of 186 cases. | we describe clinically significant infections due to streptococcus anginosus in 186 patients; 114 (61.3%) males and 72 (38.7%) females, median age 42 years, range 9 months to 93 years. in 101 (54.3%) cases s anginosus alone caused infection and in 85 (45.7%) cases it was associated with other microorganisms. abscesses accounted for 110 (59.1%) infections. sites of infection were: miscellaneous skin and soft tissue, 64 (34.4%), intraabdominal 41 (22%), head and neck 34 (18.3%), pleuropulmonary 22 ... | 1988 | 3060769 |
| in-vitro adherence of oral streptococci in the presence of sucrose and its relationship to cariogenicity in the rat. | streptococcus sanguis i gave a significantly greater percentage coverage (cell-pellicle attachment) of saliva-coated glass in the presence of sucrose than did strep. sanguis ii (p less than 0.025), and both these gave greater percentage coverages than the other species tested, between which no significant differences were noted. there was a large number of significant differences in clump size (cell-cell attachment) between species-pairs. among the mutans streptococci, there were significant dif ... | 1988 | 3166609 |
| assessment of the pathogenicity of bacterial species isolated from acute dentoalveolar abscesses. | the pathogenicity of 20 strains belonging to nine bacterial species isolated from acute dentoalveolar abscesses was assessed individually and in two species combinations by subcutaneous inoculation of mice. infections were produced by all the bacteria although variations were seen both in the type of lesion produced and the subsequent recovery of viable bacteria. anaerobic gram-negative bacilli were recovered more often (p less than 0.05) at high concentrations (10(6)-10(9) cfu/ml) and produced ... | 1988 | 3172173 |
| purulent pericarditis caused by streptococcus milleri. | streptococcus milleri was isolated in pure culture from the pericardial fluid of a 42-year-old man with pulmonary tuberculosis. pericardiectomy had to be done to cure the pericarditis. | 1988 | 3190375 |
| pig bite injuries and infection: report of seven human cases. | six patients developed local infection after being bitten or gored by swine. wounding was often deep and occurred characteristically on the posterior aspect of the thigh. severity of infection varied from simple wound infection with discharge and slough to cellulitis and abscess formation; pathogens included haemolytic streptococci, pasteurellae, bacteroides sp., proteus sp. and escherichia coli and were usually isolated in mixed culture. a patient with pasteurella aerogenes infection appears to ... | 1988 | 3215292 |
| partial characterisation of the inhibitory substances produced by streptococcus oralis and related species. | the production of inhibitory substances was sought by deferred antagonism. streptococcus oralis, streptococcus mitis and streptococcus sanguis produced bactericidal concentrations of hydrogen peroxide, but no detectable bacteriocin. actinomycetes and neisseria pharyngis were particularly susceptible to the lethal action of hydrogen peroxide. streptococcus milleri produced bactericidal concentrations of hydrogen peroxide and bacteriocin-like substances. s. oralis strains were inhibited by the bac ... | 1988 | 3216798 |
| occurrence and pathogenicity of the streptococcus milleri group. | streptococci of the milleri group are part of the normal flora of human mucous membranes. these streptococci have also been reported to be significant pathogens. like other mucosal streptococci, they may cause infective endocarditis; unlike other mucosal streptococci, however, they have also been repeatedly associated (more frequently in men than in women) with serious suppurative infections. evidence for the pathogenicity of the streptococcus milleri group is scattered and mainly circumstantial ... | 1988 | 3287560 |
| clinical features and management of two cases of streptococcus milleri chest infection. | we report 2 cases of streptococcus milleri infection of the lung. one patient, a 58-year-old woman, presented with a large abscess in a previously normal lung, the other, a 53-year-old man, had a secondary infection of lung previously scarred by tuberculosis and surgery. both patients had severe dental caries. four weeks of therapy with high dose antibiotics and physiotherapy were required. invasive techniques were needed to isolate the organism. | 1988 | 3406675 |
| purification and immunochemical studies of type b carbohydrate antigen of oral streptococcus milleri. | the type-specific antigen of serotype b streptococcus milleri was extracted with trichloroacetic acid from a purified cell wall preparation of the strain nctc 10708 and then purified on a deae-sephadex a-25 column, followed by a sephadex g-100 column. the antigen was composed of rhamnose and glucose in a molar ratio of 1.7:1.0, with a trace of galactosamine (0.1). the quantitative precipitin inhibition test with various haptenic sugars showed that rhamnose gave the greatest inhibition, whereas g ... | 1988 | 3137165 |
| serological variation in oral streptococcus milleri. | serological variation in 71 oral isolates and three reference strains of streptococcus milleri was examined. antisera were raised by immunising rabbits with cells of 10 selected strains, followed by absorption of non-specific antibodies. double diffusion of the typing sera and the rantz and randall extracts of the strains in agar gel demonstrated that 70 strains were divided into 10 serotypes (a-j) on the basis of cell-surface carbohydrate antigens. only four strains were untypable. the typing s ... | 1988 | 3139883 |
| [clinical spectrum of a common and insidious pathogen: streptococcus milleri]. | we studied the clinical significance of s. milleri isolated in our hospital in 68 patients during a 18-month period. in 51 patients (median age: 43 years, no underlying diseases in 29 patients), the isolates were associated with significant infections. they were beta-hemolytic in 32 cases and non-hemolytic in 19. the primary infection sites were the head and neck area (21 cases), the lungs (5 cases of pneumonia), the gastrointestinal tract (12 cases), the urogenital tract (3 cases), the soft tis ... | 1988 | 3051341 |

| bacteriology and antibiotic treatment of perineal suppurative hidradenitis. | a plausible bacterial pathogen (streptococcus milleri, staphylococcus aureus, anaerobic streptococcus, or bacteroides species) was isolated at least once in 26 of 32 patients with active perineal suppurative hidradenitis. the main pathogen was s milleri, whose presence was significantly associated with disease activity and whose disappearance significantly correlated with clinical improvement; s aureus nd anaerobic streptococci were also implicated. | 1988 | 3291777 |
| isolation and physiological characterization of streptococcus milleri strains from human dental plaque. | of 271 gram-positive, catalase-negative, chain-forming cocci isolated from crevicular and supragingival plaques of 22 adults, 71 stains were clustered as streptococcus milleri by testing 23 physiological characters. most of the oral s. milleri strains were nonhaemolytic and formed minute smooth colonies on glucose and sucrose agar plates, while some of the clinical strains were alpha-haemolytic, forming rough colonies on carlsson's mc agar plate as well as carrying the lancefield group antigens ... | 1988 | 3063926 |
| emphysematous septic arthritis in multiple joints due to streptococcus milleri. | a 26-year-old man with acute leukemia, treated with chemotherapy, developed emphysematous septic arthritis, due to streptococcus milleri, affecting the right knee and both shoulders. a review of the literature revealed that intraarticular gas formation is a rarely reported complication of septic arthritis. this could be the 2nd reported case of emphysematous septic arthritis due to s. milleri. | 1988 | 3164076 |
| relative cariogenicity and in-vivo plaque-forming ability of the bacterium streptococcus oralis in gnotobiotic wag/rij rats. | the rats, fed a high sucrose diet, were mono-infected with seven strains of streptococcus oralis. moderate levels of caries were induced by four strains, and three others induced low levels. approximal lesions were induced by two strains; no buccal/lingual lesions were produced. scanning electron microscopy showed that all strains colonized the tooth fissures, some strains producing a moderately abundant and dense plaque. the most cariogenic strains (pb178, pb180 and pb186) induced similar level ... | 1987 | 3479083 |
| the effects of aggregated human igg and igg-immune complexes on the agglutination of bacteria mediated by non-immunoglobulin salivary agglutinins. | non-immunoglobulin salivary agglutinins (sba) for bacteria which bind to streptococcus milleri tj7 were isolated from parotid saliva and their interactions with human igg studied. purified sba showed a single band on sodium dodecyl sulphate-polyacrylamide gel electrophoresis with a molecular weight of approx. 500,000. heat aggregated human igg (63 degrees c, 30 min), but not native igg, interacted with sba and thereby interfered with the ability of the sba to agglutinate strep. milleri. immune c ... | 1987 | 3479095 |
| fatal infection in neonates of 26 weeks' gestation due to streptococcus milleri: report of two cases. | fatal sepsis due to a particular biotype of streptococcus milleri occurred in two neonates born at 26 weeks' gestation. the clinical importance of this biotype in association with premature labour and neonatal sepsis is discussed. | 1987 | 3818983 |
| beta hemolysis in streptococcus milleri as a pathogenic factor in experimental mouse abscesses. | 1987 | 3474076 | |
| infection with streptococcus milleri. | streptococcus milleri is unique among the viridans streptococci because it produces abscesses. five serious s. milleri infections were seen in our hospital in 1 year. the english literature dealing with s. milleri was reviewed. an infection caused by s. milleri is often associated with a gastro-intestinal source. thus, the speciation of viridans streptococci from pus or blood cultures is clinically relevant. the identification of s. milleri from blood cultures suggests the possibility of serious ... | 1987 | 3819458 |
| streptococcus milleri infection of a hepatopulmonary hydatid cyst. | a case of hepatopulmonary hydatid disease in a cypriot who presented with pyogenic infection with streptococcus milleri is described. although hydatid disease and pyogenic liver abscess are both rare in the uk, an underlying echinococcal pathology should be suspected in any patient from an area endemic for hydatid who presents with a pyogenic hepatic or hepatopulmonary abscess. | 1987 | 3665896 |
| [pleural empyema due to streptococcus milleri]. | thus far little attention has been focused on the precise identification of streptococcus viridans to species level and the clinical relevance of streptococcus milleri, yet there is growing evidence that closer identification would be of significant clinical value. streptococcus milleri was identified in 142 isolates from approximately 120 patients over a period of 12 months (june 1984-may 1985) at the institute of medical microbiology, zurich university hospital. pleural empyema was the source ... | 1987 | 3303315 |
| a simplified diagnostic system for cultural detection and enumeration of streptococcus mutans. | a simple dip-slide test (cariescreen sm) based on msb selective agar was devised for detection and quantitation of streptococcus mutans in oral samples. for this test, a bacitracin tablet is dissolved in a vial containing buffered saline diluent. paraffin-stimulated saliva is collected in this diluent vial. a dip slide which incorporates a modified msb agar (minus bacitracin) is immersed briefly in the diluted saliva. after addition of a co2-generating tablet, the screw-cap dip slide is closed t ... | 1987 | 3305618 |
| a simple method for determining extracellular polysaccharide-producing ability of oral streptococci. | a simple method is described for determining the types of extracellular polysaccharides produced by oral streptococci. the method yields quantitative results in which the amount of polysaccharides produced is normalised with respect to dna. results correlate well with previously published data for oral streptococci, except in the case of streptococcus oralis for which there is no previously published data. all species within the mutans group produced both soluble and insoluble glucan; while solu ... | 1987 | 3316938 |
| streptococcus milleri and second trimester abortion. | review of 214 fetal necropsies performed in the department of pathology, university of aberdeen, showed 40 cases of chorioamnionitis or intrauterine pneumonia, five of which were associated with streptococcus milleri. in two cases there was good evidence to implicate s milleri as the cause of infected abortion while in the other cases its pathogenic role was less clear. | 1987 | 3558861 |
| isolation of streptococcus milleri from clinical specimens. | during a period of 26 months, 80 strains of streptococcus milleri were isolated from 80 patients with clinical evidence of infection. more than a third of the isolates were from lesions related to the gastro-intestinal tract and a quarter from abscesses of various other sites. the haemolytic activity and group antigenic profile of these isolates are discussed. in addition, the clinical significance of s. milleri isolated from various sites is evaluated. | 1987 | 3585033 |
| [successful treatment of a brain abscess with antibiotics and drainage puncture in an 11-year-old boy with a complex cyanotic heart defect]. | a blalock-taussig-anastomosis was performed at the age of 2 years in a boy with transposition of the great arteries, ventricular septal defect, and pulmonary atresia. nine years later he developed a transient aphasia. cranial computed tomography (ct-scan) revealed a structure compatible with brain abscess. the boy was conscious and no neurological deficit was found. initial therapy consisted of ampicillin, tobramycin, and metronidazole, 12 days later an acute hemiplegia developed. 30 ml of pus w ... | 1987 | 3587239 |

| regulation of arginine-ornithine exchange and the arginine deiminase pathway in streptococcus lactis. | streptococcus lactis metabolizes arginine by the arginine deiminase (adi) pathway. resting cells of s. lactis grown in the presence of galactose and arginine maintain a high intracellular ornithine pool in the absence of arginine and other exogenous energy sources. addition of arginine results in a rapid release of ornithine concomitant with the uptake of arginine. subsequent arginine metabolism results intracellularly in high citrulline and low ornithine pools. arginine-ornithine exchange was s ... | 1987 | 3119567 |
| hydrolytic enzymes of "streptococcus milleri". | seventy-two isolates classified as "streptococcus milleri" were examined for the presence of various hydrolytic enzymes. while no protein or lipid-degrading activities were demonstrated, some isolates showed dnase and mucopolysaccharide-degrading activities. beta-hemolytic isolates were more likely to produce these enzymes than were nonhemolytic strains. isolates of one "s. milleri" biotype (mannitol fermentation positive) were uniformly devoid of all enzyme activities tested. | 1987 | 2958496 |
| the streptococcus milleri group. | the streptococcus milleri group is newly recognized as a cause of pyogenic infection. it is important that microbiologists and physicians become aware of these organisms. the heterogeneous nature of this group of streptococci does mean that laboratories will have to use a combination of antigenic, physiologic, and hemolytic characteristics to identify these pathogenic streptococci. physicians need to recognize that these microorganisms as a group are able to cause serious infections that may req ... | 1986 | 3640746 |
| estimation of growth parameters for some oral bacteria grown in continuous culture under glucose-limiting conditions. | the coexistence of bacteria in natural environments can often be explained in terms of competition for a growth-limiting substrate(s), and the outcome of such competition depends upon relevant growth parameters such as substrate affinity and yield. dental plaque bacteria are frequently carbon and energy limited. growth parameters for seven oral streptococcus species and one actinomyces viscosus strain were estimated under glucose-limited conditions in continuous culture. in all strains, mixed-ac ... | 1986 | 3710590 |
| streptococcus milleri pyomyoma simulating infective endocarditis. | a 37-year-old woman with clinically occult, abscessed uterine myomas presented with fever, anemia, splenomegaly, and viridans streptococcal bacteremia. an initial diagnosis of endocarditis was made, but fever persisted despite appropriate antibiotics. pelvic pain evolved and laparotomy revealed an infected myoma. streptococcus milleri was isolated from both the blood and the uterine abscess. infected uterine myomata may be clinically silent despite producing sustained bacteremia. the occurrence ... | 1986 | 3737076 |
| liver abscess in crohn's disease. report of four cases and review of the literature. | four patients with liver abscesses and crohn's disease are described, and reports of 14 cases in the english language literature are reviewed. the incidence of liver abscess in patients with crohn's disease (114-297 per 100,000) appears to be higher than that of liver abscess in the general population (8-16 per 100,000). frequently the clinical manifestations of liver abscess are mistaken for a reactivation of crohn's disease, and diagnosis is delayed. in comparison to patients with liver absces ... | 1986 | 3743974 |
| [septicemia caused by arcanobacterium haemolyticum (corynebacterium haemolyticum) and streptococcus milleri]. | 1986 | 3751438 | |
| presumptive identification of "streptococcus milleri" in 5 h. | rapid miniaturized tests for acetoin production, arginine hydrolysis, and sorbitol fermentation were used for presumptive identification of non-beta-hemolytic "streptococcus milleri" isolates in 5 h. all 77 "s. milleri" strains tested were voges-proskauer positive, arginine hydrolysis positive, and sorbitol fermentation negative. on the basis of these reactions, "s. milleri" was differentiated from isolates of other viridans group streptococcal species and from streptococcus bovis. | 1986 | 3760146 |
| cavernous sinus thrombosis due to streptococcus milleri. | 1986 | 3760602 | |
| human fc(gamma) receptors for differentiation in throat cultures of group c "streptococcus equisimilis" and group c "streptococcus milleri". | the biochemical characteristics and the presence of human fc(gamma) receptors of 52 throat isolates of group c beta-hemolytic streptococci were examined. among these isolates, 38 were identified as "streptococcus milleri" and 14 were identified as "streptococcus equisimilis." the differentiation of group c "s. equisimilis" from "s. milleri" with identical group antigens was easy to perform by the measurement of the size of the hemolytic zone on a sheep blood agar plate in an anaerobic atmosphere ... | 1986 | 3771760 |
| quantitative bacteriology of acute dento-alveolar abscesses. | a qualitative and quantitative bacteriological study was performed on pus specimens obtained by needle aspiration of 50 acute dento-alveolar abscesses. most samples contained a mixture of species (average 3.3); 20 (40%) of the abscesses contained anaerobes alone, 3 (6%) contained facultative anaerobes only and the remaining 27 (54%) contained mixtures of both types of bacteria, with anaerobes predominating. in total, 166 bacterial strains were isolated, 75% of which were strictly anaerobic; the ... | 1986 | 2869147 |
| is "primary" subphrenic abscess caused by streptococcus milleri a result of unrecognized gastrointestinal perforation? | an unusual case of subphrenic abscess presenting as empyema of the pleural cavity is described. the abscess developed secondarily to an occult perforation of the gastrointestinal tract, which was, diagnosed indirectly by the discovery of a fishbone within the abscess. isolation of streptococcus milleri from the pus was an important clue for the existence of an underlying gastrointestinal pathology. | 1986 | 3520131 |
| comparative adhesion of seven species of streptococci isolated from the blood of patients with sub-acute bacterial endocarditis to fibrin-platelet clots in vitro. | the adhesion to fibrin-platelet clots in vitro of 21 strains of streptococci isolated from the blood of patients with sub-acute bacterial endocarditis (sabe) was measured. the species, in order of greatest adhesion, were streptococcus faecalis, streptococcus mutans, streptococcus milleri, streptococcus sanguis, dextran-positive streptococcus mitior, dextran-negative streptococcus mitior and streptococcus salivarius. individual strains within species, however, cannot be assumed to be representati ... | 1986 | 2422150 |

| occurrence of streptococcus milleri among beta-hemolytic streptococci isolated from clinical specimens. | a total of 256 beta-hemolytic streptococcal isolates were subjected to serological and physiological tests to identify those which could be classified as streptococcus milleri. s. milleri accounted for 75% of 70 group c isolates, 15% of 69 group g isolates, 75% of 16 nongroupable isolates, and 100% of 20 group f isolates examined. no s. milleri isolates were encountered among the 90 group a streptococci studied. of the 95 beta-hemolytic s. milleri isolates examined, 81% were recovered from respi ... | 1985 | 4031029 |
| fatty acid composition of streptococcus milleri. | the cellular fatty acids of 31 strains belonging to the streptococcus milleri group were analysed by capillary gas-liquid chromatography. results were compared with findings from biochemical differentiation of the strains into streptococcus constellatus (two strains), streptococcus anginosus (16 strains) and streptococcus intermedius (13 strains). eight strains of various other streptococci were included as internal references, including three strains of streptococcus morbillorum, three strains ... | 1985 | 4043056 |
| the cariogenicity of sucrose, glucose and maize starch in gnotobiotic rats mono-infected with strains of the bacteria streptococcus mutans, streptococcus salivarius and streptococcus milleri. | twenty-one-day-old weanling gnotobiotic wag/rij rats were mono-infected with streptococcus mutans nctc 10832, streptococcus salivarius jmb or streptococcus milleri nctc 11169, and maintained on a high carbohydrate diet containing sucrose, glucose or maize starch for 21-days. fissure caries developed with all combinations of streptococcal strain and carbohydrate except maize starch/streptococcus salivarius jmb. caries incidence was highest with streptococcus mutans nctc 10832. for all species, th ... | 1985 | 3868967 |
| incidence and characterization of beta-hemolytic streptococcus milleri and differentiation from s. pyogenes (group a), s. equisimilis (group c), and large-colony group g streptococci. | the biochemical characteristics of 172 clinical isolates of group a, c, f, or g or "nongroupable" beta-hemolytic streptococci were examined. among these isolates, 91 were identified as beta-hemolytic strains of streptococcus milleri. the remaining isolates included 20 streptococcus pyogenes, 21 streptococcus equisimilis, 37 large-colony group g streptococci, and 3 unidentified nongroupable isolates. a majority (84%) of the s. milleri strains possessed lancefield group antigen (3 a, 27 c, 41 f, a ... | 1985 | 3902878 |

| streptococcus milleri in appendicitis in children. | a retrospective survey of 253 appendectomies performed on children over a period of one year was carried out. streptococcus milleri was isolated from pus in 11 (29%) of the 38 children who developed postoperative infections; it was the most commonly identified pathogen in these children. it is concluded that s milleri is a significant pathogen in childhood appendicitis, and that this fact should be taken into account when antibiotic therapy is being planned. | 1985 | 3973813 |
| streptococcus milleri endocarditis complicated by myocardial abscess. | a patient with streptococcus milleri endocarditis and myocardial abscess was bacteriologically cured after surgical intervention and six weeks of parenteral penicillin therapy plus two weeks of gentamicin therapy. studies of the bacterial isolate suggest that gentamicin added no therapeutic advantage to the antimicrobial regimen. this case demonstrates that local cardiac suppurative complications can occur during endocarditis caused by s milleri, and suggests that speciation of alpha-hemolytic s ... | 1985 | 4012392 |
| streptococcus milleri as a cause of pleural empyema. | review of an annual series of cases of empyema seen at a regional cardiothoracic unit showed that six out of 25 were due to streptococcus milleri. the details of the cases are summarised. this organism is now an important cause of empyema, occurring much more commonly in men than in women; but since it is highly sensitive to penicillins permanent resolution can be achieved with antibiotic treatment combined with open or closed drainage. | 1985 | 4035635 |
| clinical significance of streptococcus milleri. | the clinical features of infection in patients from whom streptococcus milleri was isolated were analysed in an attempt to determine the clinical significance of this organism. during a four-year period streptococcus milleri was isolated from 232 hospitalized patients. in 44 patients streptococcus milleri was isolated in pure culture, in 45 patients together with obligate anaerobes, and in 143 patients together with aerobes with or without anaerobes. the 82 patients in whom isolation of streptoc ... | 1985 | 4043055 |
| brain abscess in children due to streptococcus milleri. a report of 2 cases. | brain abscesses due to streptococcus milleri occurring in 2 previously healthy children are reported. both children had evidence of liver involvement and both responded well to antibiotic treatment. | 1985 | 4060032 |
| the effect of growth rate on the adhesion of the oral bacteria streptococcus mutans and streptococcus milleri. | as a preliminary to measuring the hydrophobicity of continuous-culture cells, batch-grown cells of a number of streptococcus mutans strains were tested for their ability to adhere to hexadecane. the hydrophobic properties of such cells were markedly affected by experimental variables such as the composition of the growth medium and the buffer in which the cells were subsequently suspended. for example, the replacement of glucose by fructose in a chemically-defined growth medium (cdm) increased c ... | 1984 | 6586118 |

| genetic exchange between oral streptococci during mixed growth. | to determine whether oral streptococci might exchange genetic information in the oral cavity, paired transformable strains of streptococcus mutans, streptococcus sanguis and streptococcus milleri were growth together. chromosomal and plasmid-borne antibiotic resistance markers could be readily transferred from s. mutans gs-5 to s. milleri nctc 10707 or s. sanguis challis during mixed growth. however, no exchange from the latter two organisms to strain gs-5 could be detected under these condition ... | 1984 | 6512502 |
| the production of dental plaque and caries by the bacterium streptococcus salivarius in gnotobiotic wag/rij rats. | the abilities of ten strains of streptococcus salivarius to colonize rat molars and to induce caries were determined using mono-infected germ-free rats. scanning electron microscopy revealed the production of micro-colonies and spheroids by strep. salivarius on exposed surfaces of molar teeth, and abundant dense plaque formation in fissures. most strains colonized fissures and smooth surfaces as effectively as streptococcus mutans nctc 10832, yet produced no buccal or lingual lesions. the four k ... | 1984 | 6589986 |
| in-vivo dental plaque-forming ability and relative cariogenicity of the bacteria streptococcus mitis and streptococcus sanguis i and ii in mono-infected gnotobiotic rats. | sixteen strains of streptococcus mitis, streptococcus sanguis i and strep. sanguis ii were tested for cariogenic potential and in-vivo plaque-forming ability in a gnotobiotic wag/rij rat test system. all strains produced far less fissure plaque in vivo than strains of streptococcus milleri or streptococcus mutans. there was less extracellular matrix around cells of strep. mitis or strep. sanguis than around strep. mutans, in the fissures. dense sheets of cells were observed only with strep. muta ... | 1984 | 6598361 |
| thoracic empyema due to streptococcus milleri: four cases. | four cases of streptococcus milleri empyema occurring over a six month period are reported. empyema was post-pneumonic in three patients and followed blunt abdominal and chest trauma in one patient. there was an absence of serious underlying disease in these patients and management consisted of tube drainage, lavage of the pleural space and prolonged intrapleural and systemically administered antibiotic therapy. complete recovery was achieved in three patients and a satisfactory result in the ot ... | 1984 | 6595567 |
| pyogenic liver abscess caused by streptococcus milleri. case reports. | in recent years streptococcus milleri has emerged as an important cause of pyogenic liver abscess. whether this represents a changing epidemiological pattern or merely reflects the more widespread application of routine anaerobic bacterial culture techniques is unclear. the isolation of strept. milleri on culture of a blood specimen from a patient presenting with a pyrexial illness should alert the clinician to the possibility of an underlying liver abscess. although it is isolated anaerobically ... | 1984 | 6701704 |
| complications of sinusitis caused by streptococcus milleri. | complications of sinusitis caused by 'viridans' streptococci, mainly streptococcus milleri, are described. the identification, bacteriology and pathogenicity of the organism are discussed and an approach to antimicrobial therapy outlined. | 1984 | 6148372 |
| characterization of oral streptococci that activate the dietary glycoside rutin to a mutagen. | oral streptococci are described that hydrolyze the dietary glycoside rutin (cas: 153-18-4), resulting in mutagenic activity. bacteria that hydrolyze rutin were isolated from the mouth of each of 10 healthy volunteers. the activity was inducible, and the product was mutagenic in the salmonella mutagenicity assay. these bacteria were present in the greatest proportion on the dorsum of the tongue where they formed 1.5% of the total cultivable microflora. the appearance of the colonies, cell morphol ... | 1984 | 6381853 |
| pyogenic liver abscess: diagnosis, bacteriology and treatment. | pyogenic liver abscess is an uncommon but potentially fatal disease. the accuracy of diagnosis made on clinical grounds can now be greatly improved with the use of modern organ-imaging techniques. the condition is often polymicrobial: escherichia coli and other enteric gram-negative rods are major pathogens, with anaerobic gram-negative rods and streptococcus milleri being increasingly recognised. staphylococcal liver abscesses are less common, often arising in association with neutrophil disord ... | 1984 | 6396090 |
| trimethylsilyl-sugar profiles of streptococcus milleri and streptococcus mitis. | seventy strains of 'viridans-group' streptococci were analysed gas chromatographically after preparation of trimethylsilyl ethers of their cellular sugars. the resulting profiles were evaluated as a possible aid to taxonomy. glycerol, glucose, galactose, n-acetyl-glucosamine and n-acetylmuramic acid were found in all strains, in varying amounts. rhamnose was the major neutral sugar in most strains, other than representatives of streptococcus mitis, which invariably had ribose and usually anhydro ... | 1983 | 6409876 |
| streptococcus milleri causing infection in man. | we describe the microbiological and morphological characteristics of 151 strains of streptococcus milleri isolated during the course of routine bacteriological investigations. although these strains formed a fairly heterogeneous group, several constant features were identified which typify the species. strept. milleri emerged as a major cause of pyogenic infection, clinical disease being characterized by localized collections of pus in almost every organ system. bacteraemia due to strept. miller ... | 1983 | 6342167 |
| streptococcus milleri and surgical sepsis. | for many years viridans streptococci have been considered as commensal organisms in a wide variety of sites in the human body and only regarded as significant pathogens in subacute bacterial endocarditis. however, in recent years some reports have suggested that a particular species, streptococcus milleri, can be a virulent pathogen, producing life-threatening sepsis particularly in surgical patients. we review here our experience of this organism in 23 general surgical patients over a 3 year pe ... | 1983 | 6830135 |

| streptococcus milleri empyema. | a 58-year-old woman who had recurrent aspiration due to atlantoaxial subluxation, a complication of rheumatoid arthritis, had s milleri empyema. this organism has been associated with purulent disease in previous series, and may be a relatively common but unrecognized cause of empyema. | 1983 | 6623151 |
| chronic meningitis caused by a penicillin-sensitive microorganism? | 21 patients studied had persistent or progressive chronic meningitis not associated with a demonstrable infectious or other disease, except streptococcus milleri antigen in the cerebrospinal fluid of 1 patient. the cerebrospinal-fluid (csf) abnormalities consisted of a moderate, predominantly mononuclear, pleocytosis, a sharp rise in csf protein (mean 2.3 g/l), intrathecal synthesis of considerable quantities of oligoclonal immunoglobulin g, and, in half the patients, a fall in the csf-glucose/b ... | 1983 | 6134962 |
| activation of rutin by human oral bacterial isolates to the carcinogen-mutagen quercetin. | oral streptococci, isolated from the mouths of 2 healthy subjects, hydrolysed innocuous rutin, a flavonoid glycoside, to its genotoxic aglycon quercetin, in vitro. the isolates were identified as streptococcus milleri. the glycosidase, rutinase, was studied in cell-free extracts derived from one of the isolates, grown anaerobically in batch cultures by the use of a bioassay, the ames test, in which s-9 was replaced by the cell-free extracts. this streptococcal rutinase was: constitutive, partly ... | 1983 | 6579892 |
| predominant cultivable microflora of plaque on removable dentures in patients with healthy oral mucosa. | plaque from the fitting surface of upper full dentures in eight patients with healthy palatal mucosa was studied. to characterize the predominant cultivable flora, 916 isolates (100-128 from each sample) were subcultured from anaerobic roll-tubes. streptococci constituted 0-81 per cent (median, 41 per cent) of the isolates with varying proportions of streptococcus milleri, streptoccus mutans, streptococcus salivarius, streptococcus mitior and streptococcus sanguis. staphylococcus aureus made up ... | 1983 | 6579900 |

| bacteriology of dental abscesses of endodontic origin. | aspirates have been cultured from 10 dental abscesses of endodontic origin, all of which had penetrated beyond the bony alveolus to produce fluctuant swelling. sampling was by syringe aspiration. strict anaerobic techniques, including the use of an anaerobic chamber, were used for serial dilution and plating. randomly selected colonies (100) from each culture were purified, characterized, and identified. seventy percent of the bacterial isolates were either strict anaerobes or microaerophilic. o ... | 1983 | 6630460 |
| distribution and incidence of viridans streptococcal species in routine clinical specimens. | five hundred consecutive isolates of viridans streptococci were identified to the species level in an effort to determine their distribution and incidence in routine clinical specimens. viridans streptococci accounted for significant percentages of streptococcal isolates from urine, wounds, body fluids, and blood. the most commonly isolated strains belonged to the streptococcus milleri, streptococcus mitis, streptococcus sanguis i, and streptococcus sanguis ii species. patient charts were review ... | 1983 | 6637890 |
| spontaneous bacterial peritonitis caused by a viridans streptococcus or neisseria perflava. | eight patients had nine episodes of presumed spontaneous bacterial peritonitis (sbp) caused by commensal bacteria that usually inhabit the oropharynx, including neisseria perflava and the viridans streptococci streptococcus milleri, streptococcus mitis, and streptococcus sanguis. nonpurulent ascites (ascitic fluid wbc count, less than 1,000/cu mm) was present in four episodes, possibly caused by either bacterial colonization or early peritonitis; purulent ascites was present in five episodes. no ... | 1983 | 6645030 |
| possible heterogeneity of streptococcus milleri determined by dna mol % (guanine plus cytosine) measurement and physiological characterization. | dna base pair ratios (mol % guanine + cytosine) were calculated, for eighteen strains of streptococcus milleri, from measurements of dna melting temperature (tm). strains of vaginal origin which were also 'atypical' physiologically had a value of 40.3. the two culture collection of 'minute' beta-haemolytic strains of lancefield groups g and f had values of 36.8 and 38.8 mol%, respectively. three other reference strains had a dna guanine plus cytosine content ranging from 40.4 to 43.0 mol%, inclu ... | 1983 | 6645981 |
| perineal crohn's disease complicated by pyogenic liver abscess during metronidazole therapy. | a patient with ileal and perineal crohn's disease developed a pyogenic liver abscess caused by streptococcus milleri. the perineal process had been treated with high-dose metronidazole for the preceding 6 mo, and culture of a perianal abscess 2 mo before admission revealed heavy growth of streptococcus milleri (which was misidentified as an anaerobic peptostreptococcus). this case illustrates the difficulty in correctly identifying streptococcus milleri, the most frequent isolate from pyogenic l ... | 1983 | 6852451 |
