| septic cavernous sinus thrombosis complicated by narrowing of the internal carotid artery, subarachnoid abscess and multiple pulmonary septic emboli. | a 56-year-old woman was admitted because of a high fever, right ptosis, chemosis, proptosis and ocular muscle palsy. cranial mri revealed a cavernous sinus thrombosis and a subarachnoid abscess. carotid angio-gram demonstrated marked stenosis as well as aneurismal formation of the right internal carotid artery at the intracavernous portion. chest radiograph showed bilateral multiple pulmonary nodules, some of which contained a cavity. blood culture was positive for streptococcus constellatus. sh ... | 2007 | 17380002 |
| pyogenic liver abscess presenting after malignant polypectomy. | streptococcus bovis bacteremia has been linked to the presence of occult colon cancer since 1977. we present a case of pyogenic liver abscess and bacteremia with a different streptococcus viridans 1 week after colonic adenocarcinoma was removed via polypectomy, discuss the likely etiology and review whether there is evidence to support looking for colon cancer in patients who present similarly but have not already undergone screening. | 2007 | 17406839 |
| brain abscess following dental procedures. case report. | there have been a number of reports of brain abscess suggesting an odontogenic etiology after dental treatment procedures or oral infections, but the diagnosis was mainly by exclusion rather than based on evidence. we present a case of a brain abscess due to strepto-coccus constellatus in a 27-year-old-immunocompetent woman who underwent extraction of the primary molar and eradication of a radicular cyst some weeks before. | 2007 | 17529917 |
| streptococcus milleri group infection associated with digestive fistula in patients with vascular graft: report of seven cases and review. | we described seven patients with streptococcus milleri group aortic (six patients) or vena cava (one patient) graft infection secondary to a vasculo-digestive fistula. time between vascular graft setting and first clinical signs varied from eight months to more than thirteen years. six patients had fever. three patients presented with recurrent fever for more than nine months and in two of these cases, delay before diagnosis was long because repeated blood cultures were sterile. three patients h ... | 2007 | 17565461 |
| embolic myocardial infarction and left ventricular rupture due to mitral valve endocarditis. | a left ventricular rupture due to embolic myocardial infarction is extremely rare. a 72-year-old woman developed an acute embolic myocardial infarction and mitral regurgitation due to infective endocarditis. two days after the infarction, a left ventricular free wall rupture occurred after transesophageal echo examination. she received an epicardial patch and mitral valve replacement. perioperatively, an intra-aortic balloon pump and long-term antibiotics were used. the postoperative course was ... | 2007 | 17592432 |
| septic cavernous sinus thrombosis with bilateral secondary orbital infection. | cavernous sinus thrombosis may occur as a secondary threatening condition to spread from local or distant foci of infection. we report a case where secondary retrograde spread occurred to both the ipsilateral and contralateral orbits with very different clinical manifestations. to our knowledge such spread is unreported. the case highlights the difficulty in recognising orbital collections when venous engorgement secondary to a cavernous sinus thrombosis coexists and demonstrates how the prognos ... | 2007 | 17613858 |
| [necrotizing fasciitis complicating transthoracic biopsy]. | necrotizing fasciitis is a rapidly progressive and often fatal infection of the soft-tissue fascia deep to the skin but superficial to the muscles. we report a case of necrotizing fasciitis of the anterior chest wall complicating a percutaneous needle biopsy. | 2007 | 17978740 |
| streptococcus constellatus and prevotella bivia penile abscess. | streptococcus constellatus (s. constellatus) is known to cause abscesses in the oral, genitourinary, and gastrointestinal tracts, frequently in association with anaerobic bacteria. we report a rare case of s. constellatus and prevotella bivia (p. bivia) causing a penile abscess, which was successfully treated with surgical drainage and antibiotic treatment. | 2007 | 17982605 |
| rapid differentiation between members of the anginosus group and streptococcus dysgalactiae subsp. equisimilis within beta-hemolytic group c and g streptococci by pcr. | based on a pair of primers developed initially for differentiating the anginosus group from other viridans streptococci, the pcr reported here can also differentiate between members of the anginosus group and streptococcus dysgalactiae subsp. equisimilis among beta-hemolytic group c and g streptococci. the resulting 742-bp pcr product was specific for members of the anginosus group, although a smaller, nonspecific product (361 bp) was generated from s. dysgalactiae subsp. equisimilis. restrictio ... | 2006 | 16672416 |
| hypertrophic osteoarthropathy secondary to vascular prosthesis infection: report of 3 cases and review of the literature. | an infected vascular graft is an uncommon association in hypertrophic osteoarthropathy (hoa) but is important because of potential catastrophic complications. here we describe 3 new patients with hoa secondary to vascular prosthesis infection and review the other 23 patients described in the english literature with this clinical syndrome. the finding of symptoms and signs of localized hoa in patients with arterial prosthesis may be the presenting manifestation of graft sepsis. in most patients t ... | 2006 | 16721260 |

| [streptococcus constellatusas a causative agent of empyema. report of one case]. | streptococcus constellatus is a commensal microorganism in man but may cause infections in different locations. we report a 59 years old male with severe sequelae of a previous cerebrovascular accident that consulted in the emergency room for fever of 15 days of evolution. a right empyema was diagnosed. the bacteriological culture of the effusion disclosed the presence of streptococcus constellatus and two anaerobic strains (prevotella intermedia and fusobacterium urealyticus). the patient was t ... | 2006 | 17130992 |
| in vitro activity of sitafloxacin compared with several fluoroquinolones against streptococcus anginosus and streptococcus constellatus. | the in vitro activities of sitafloxacin and seven other fluoroquinolones a (ciprofloxacin, tosufloxacin, sparfloxacin, levofloxacin, t-3811me, moxifloxacin and trovafloxacin) were examined by the microdilution method against 79 clinically isolated 'streptococcus milleri' group (smg) microorganisms. no statistically significant differences were found between the minimum inhibitory concentrations (mic(50) and mic(90)) against streptococcus anginosus and streptococcus constellatus. sitafloxacin was ... | 2006 | 16417990 |
| acute glomerulonephritis associated with streptococcus pyogenes with concomitant spread of streptococcus constellatus in four rural families. | we studied history, renal histopathology and microbiology of an epidemic of acute glomerulonephritis associated with throat infections and uncommon culture results in four neighbour families. a 40-year-old man (index patient) was referred to a university hospital for dialysis and kidney biopsy due to a suspected acute glomerulonephritis. an acute tonsillitis had preceded the condition. penicillin treatment had been started four days before the discovery of renal failure. throat swabs were positi ... | 2005 | 16454159 |
| phototargeting oral black-pigmented bacteria. | we have found that broadband light (380 to 520 nm) rapidly and selectively kills oral black-pigmented bacteria (bpb) in pure cultures and in dental plaque samples obtained from human subjects with chronic periodontitis. we hypothesize that this killing effect is a result of light excitation of their endogenous porphyrins. cultures of prevotella intermedia and p. nigrescens were killed by 4.2 j/cm2, whereas p. melaninogenica required 21 j/cm2. exposure to light with a fluence of 42 j/cm2 produced ... | 2005 | 15793117 |
| oral campylobacter species involved in extraoral abscess: a report of three cases. | oral campylobacter species are rarely reported to cause extraoral infections. here we present three cases of extraoral abscess caused by an oral campylobacter sp. and a streptococcus sp. the campylobacter species were all isolated anaerobically and identified by sequencing analysis of the 16s rrna gene. the cases included a breast abscess caused by campylobacter rectus and a non-group a beta-hemolytic streptococcus in a patient with lymphoma, a liver abscess caused by campylobacter curvus and an ... | 2005 | 15872299 |
| experimental abscess formation caused by human dental plaque. | human dental plaque consists of a wide variety of microorganisms, some of which are believed to cause systemic infections, including abscesses, at various sites in the body. to confirm this hypothesis experimentally, we examined the abscess-forming ability of native dental plaque in mice, the microbial features of the infectious locus produced by the plaque, and the anti-phagocytic property of microbial isolates. aliquots of a suspension of supragingival dental plaque containing 6 x 10(6) colony ... | 2005 | 15905601 |
| microarrays complement culture methods for identification of bacteria in endodontic infections. | the aim of this study was to investigate the microbial composition of necrotic root canals using culture methods and microarray technology. twenty uniradicular teeth with radiographic evidence of periapical bone loss and with no previous endodontic treatment were selected for this study. for molecular diagnosis a dna chip with 20 different species-specific, 16s-rdna-directed catcher probes was used. the microorganisms most frequently detected by the dna chip were: micromonas micros, fusobacteriu ... | 2005 | 15943771 |
| chorioamnionitis associated with crohn's disease and azathioprine treatment: a case report. | this paper reports a case of s. constellatus chorioamnionitis in a pregnant crohn's disease patient who was taking azathioprine. chorioamnionitis is a major cause of perinatal morbidity. azathioprine, an immunosuppressive antimetabolite, is widely used to treat inflammatory bowel disease. streptococcus constellatus is a gram-positive bacterium that has not previously been associated with chorioamnionitis. a high index of suspicion for chorioamnionitis and unusual pathogens should be maintained i ... | 2005 | 16014435 |
| orbital abscess: visual loss following extraction of a tooth--case report. | objective: it is the purpose of this article to alert the general practitioner to the severe consequences that may result from a tooth extraction, including the loss of vision, despite the use of antibiotics. conclusions: early and aggressive treatment is critical in obstructing the spread of infection toward the orbits, the eyes, and eventually the brain. | 2005 | 16182155 |
| platelet responses and anaphylaxis-like shock induced in mice by intravenous injection of whole cells of oral streptococci. | intravenous injection of lyophilized whole cells of various oral streptococcal strains into muramyldipeptide (mdp)-primed c3h/hen mice induces rapid anaphylactoid shock. here we examined the mechanism underlying this shock. in non-primed mice, streptococcus intermedius k-213k (sik213) and streptococcus constellatus t21 (sct21) produced little or no sign of shock. in mdp-primed mice, sik213 caused lethal shock, while sct21 only had a weak effect. sik213 induced decreases in blood platelets and 5- ... | 2004 | 14678471 |
| identification of the anginosus group within the genus streptococcus using polymerase chain reaction. | the aim of this study was to establish an identification method for the anginosus group within the genus streptococcus by polymerase chain reaction (pcr). using a primer pair based on the group-specific sequences of penicillin-binding protein 2b (pbp2b) gene, a 275-bp fragment was amplified from each species in the group but no size-matched products were obtained in other streptococci. further identification in the species or subspecies level was possible by a multiplex pcr with primers for the ... | 2004 | 15043873 |
| streptococcus constellatus causing myocardial abscess complicated by cerebritis. | streptococcus constellatus infection is a rare cause of myocardial abscess. the complication of cerebritis is also rare. we report a case of s. constellatus bacteremia in a 21-year-old woman who developed fever and watery diarrhea 7 days prior to admission. computed tomography of the brain showed severe effacement of the cerebral sulci, narrowing of the ventricular system, and severe brain swelling. echocardiography showed a cystic lesion of about 2 cm(2) over the left atrium. mannitol and dexam ... | 2004 | 15060690 |
| mycotic aneurysm caused by streptococcus constellatus subsp. constellatus. | an infected mycotic aneurysm due to streptococcus constellatus subsp. constellatus has not previously been reported. we report on this condition in an 87-year-old woman who had aggravating abdominal pain and a large fusiform aneurysm over the thoracic-abdominal aorta with mural thrombus. isolates from two sets of blood cultures and the debrided tissue were identified as s. constellatus subsp. constellatus by their biochemical reaction profiles, compatible 16s rrna gene sequencing results, and se ... | 2004 | 15071061 |

| [a case of spinal epidural abscess associated with retropharyngeal abscess]. | spinal epidural abscesses are known to occur associated with retropharyngeal abscess, but such cases are few in the literature. we treated a 72-year-old woman who reported pain in the back of the neck. computed tomography (ct) showed a retropharyngeal abscess extending to the upper neck through the carotid space on the left side and an magnetic resonance imaging (mri) showed a spinal epidural abscess without cervical vertebral osteomyelitis. the abscess was assumed to reach the epidural space al ... | 2002 | 12491595 |
| interaction between human polymorphonuclear leukocytes and streptococcus milleri group bacteria. | because streptococcus milleri group (smg) bacteria--streptococcus constellatus, streptococcus intermedius, and streptococcus anginosus--exhibit a striking propensity to cause abscesses, the interaction of these organisms with human polymorphonuclear leukocytes (pmnl) was examined. after incubation in pooled normal human serum, smg stimulated less chemotaxis than did staphylococcus aureus, in contrast to viridans streptococci, which caused greater chemotaxis than did s. aureus. pmnl ingested grea ... | 2002 | 11756985 |
| [acute subdural abscess due to mixed infection of eikenella corrodens and streptococcus constellatus]. | eikenella corrodens is a gram-negative, facultative anaerobic rod that frequently exists as part of normal human flora in the upper respiratory tract and gastrointestinal tract. recently, e. corrodens is reported as a rare causative agent of empyematic lesion. we report a case of 10-year-old girl with acute subdural abscess. she developed a high grade fever, swelling of the left periorbital area, right sided partial seizure and hemiplegia. brain ct and mri showed left parietal subdural abscess. ... | 2001 | 11766381 |
| [clinical and bacteriological significance of the streptococcus milleri group in deep neck abscesses]. | streptococcus constellatus, s. intermedius, and s. anginosus, the three species of the s. milleri group, form part of the normal flora most commonly found in the mouth, throat, gastrointenstinal tract, and genital tract. the s. milleri group has become known as an important pathogen in abscess disease, but little attention has been paid to their role in deep neck abscesses. we have treated 9 patients with deep neck abscesses relating to the s. milleri group since 1991, and regarded this group as ... | 2001 | 11257779 |
| streptococcus salivarius fimbriae are composed of a glycoprotein containing a repeated motif assembled into a filamentous nondissociable structure. | streptococcus salivarius, a gram-positive bacterium found in the human oral cavity, expresses flexible peritrichous fimbriae. in this paper, we report purification and partial characterization of s. salivarius fimbriae. fimbriae were extracted by shearing the cell surface of hyperfimbriated mutant a37 (a spontaneous mutant of s. salivarius atcc 25975) with glass beads. preliminary experiments showed that s. salivarius fimbriae did not dissociate when they were incubated at 100 degrees c in the p ... | 2001 | 11292790 |
| antibiotic susceptibilities of genetically characterized streptococcus milleri group strains. | previous studies of the antibiotic susceptibility of streptococcus milleri group organisms have distinguished among species by using phenotypic techniques. using 44 isolates that were speciated by 16s rrna gene sequencing, we studied the mics and minimum bactericidal concentrations of penicillin, ampicillin, ceftriaxone, and clindamycin for streptococcus intermedius, streptococcus constellatus, and streptococcus anginosus. none of the organisms was resistant to beta-lactam antibiotics, although ... | 2001 | 11302819 |
| streptococcus intermedius, streptococcus constellatus, and streptococcus anginosus ("streptococcus milleri group") are of different clinical importance and are not equally associated with abscess. | difficulties in distinguishing organisms of the "streptococcus milleri group" (smg; streptococcus intermedius, streptococcus constellatus, and streptococcus anginosus), have caused ambiguity in determining their pathogenic potential. we reviewed 118 cases in which smg isolates had been identified using 16s rdna sequence. s. constellatus and s. anginosus were isolated far more frequently than was s. intermedius. nearly all isolates of s. intermedius and most isolates of s. constellatus, but only ... | 2001 | 11317256 |
