| classical bacterial diarrhea: perspectives and update--salmonella, shigella, escherichia coli, aeromonas and plesiomonas. | impressive advancements in our understanding of the mechanisms of diarrhea production and of the epidemiologic importance of these "classical" bacterial enteropathogens have been accomplished, but many areas are in need of further exploration. the recent development of gene probes and enzyme-linked immunosorbent assays for the identification of epec, etec and eiec will enhance immeasurably the ability to carry out large scale epidemiologic studies which are still needed to clarify the global imp ... | 1986 | 3511463 |
| a collaborative evaluation of a rapid, semi-automated identification system for gram-negative bacilli: the quantum ii bid. | the recently-introduced semi-automated bacterial identification system, the quantum ii bid, is designed to identify fermentative and non-fermentative gram-negative bacilli in 4-5 h. the system was evaluated independently by the two participating laboratories. inter-laboratory reproducibility was determined by testing 181 strains in each laboratory and found to be 97.8%. a further 893 organisms, comprising 417 fresh clinical isolates and 476 stock cultures, were then tested by the system in the t ... | 1986 | 3512840 |
| same day identification of gram-negative rods with the quantum ii microbiology system. | the quantum ii microbiology system was challenged with 479 strains of enterobacteriaceae and 155 strains of nonfermenters (contained in the data base) and aeromonas/plesiomonas. the percentages of strains correctly diagnosed within 5h (i.e., with out additional tests) at greater than or equal to 80% probability were 78% and at greater than or equal to 50% probability, 84.7%. | 1986 | 3512962 |
| bacterial diarrhoea. | bacterial infections are important causes of diarrhoea in infants and children, particularly in developing countries and in other settings where standards of personal and community hygiene are low. knowledge of bacterial diarrhoeas has been significantly expanded in recent years by the finding that many episodes of acute diarrhoea are due to infections with bacteria which produce enterotoxins that interfere with intestinal fluid and electrolyte transport (the 'enterotoxigenic' diarrhoeas). sever ... | 1986 | 3514008 |
| identification of enteric pathogens in the small and large intestine of children with diarrhea. | enteric pathogens were identified in children with diarrhea from duodenal specimens obtained with a string capsule and from fecal specimens. rotavirus was identified in stools of 43 of 100 children, and was recovered from the small intestine from nine (21%) children who were excreting this virus. shigella was isolated from stools from 22, salmonella from 17, enterotoxigenic escherichia coli from eight, and aeromonas hydrophila from one of 100 children with diarrhea. in contrast to rotavirus, sal ... | 1986 | 3516549 |
| comparison of the quantum ii bacterial identification system and the automicrobic system for the identification of gram-negative bacilli. | the quantum ii bacterial identification system (bid; abbott laboratories) is a microprocessor-based spectrophotometric system for identification within 4 to 5 h of both enteric and nonenteric gram-negative bacilli. we compared the bid with the automicrobic system (ams; vitek systems, inc.), using the most recent gram-negative identification card and software (ams-gni), for the identification of 501 clinical isolates of gram-negative bacilli, including 382 belonging to the enterobacteriaceae and ... | 1986 | 3517034 |
| feasibility of same-day identification of members of the family vibrionaceae by the api 20e system. | sixty isolates, comprising nine species of the family vibrionaceae, were tested with the api 20e 5-h same-day procedure (analytab products, plainview, n.y.). included were 27 aeromonas hydrophila isolates, 10 aeromonas sobria isolates, 7 aeromonas caviae isolates, 3 plesiomonas shigelloides isolates, 3 vibrio alginolyticus isolates, 3 vibrio cholerae isolates, 1 vibrio fluvialis isolate, 5 vibrio parahaemolyticus isolates, and 1 vibrio vulnificus isolate. the 5-h profile numbers were specific fo ... | 1986 | 3517061 |
| cloning, expression, and mapping of the aeromonas hydrophila aerolysin gene determinant in escherichia coli k-12. | dna sequences corresponding to the aerolysin gene (aer) of aeromonas hydrophila ah2 dna were identified by screening a cosmid gene library for hemolytic and cytotoxic activities. a plasmid containing a 5.8-kilobase ecori fragment of a. hydrophila dna was required for full expression of the hemolytic and cytotoxic phenotype in escherichia coli k-12. deletion analysis and transposon mutagenesis allowed us to localize the gene product to 1.4 kilobases of aeromonas dna and define flanking dna region ... | 1986 | 3522552 |
| etiology and epidemiology of travelers' diarrhea in asia. | travelers' diarrhea in asia has been studied among peace corps volunteers in thailand, japanese travelers, foreign residents in bangladesh, guests in hotels, and members of various tour groups. rates of diarrheal attack of greater than 50% during four- to six-week sojourns were reported for these groups. among travelers with diarrhea, the most commonly isolated pathogen was enterotoxigenic escherichia coli (20%-34%), followed by salmonella (11%-15%), shigella (4%-7%), campylobacter (2%-5%), and ... | 1986 | 3523709 |
| multiple low-level antibiotic resistance in aeromonas salmonicida. | mutants with multiple low-level antibiotic resistance were isolated from virulent wild-type aeromonas salmonicida strains exposed to a low concentration of any one of several low-molecular-mass (approximately 635 daltons or less) antibiotics. multiple resistance was toward beta-lactam compounds (penicillin g, ampicillin, cloxacillin), quinolones (flumequine, oxolinic acid, nalidixic acid), tetracyclines, chloramphenicol, and novobiocin. susceptibilities of the mutants toward several higher-molec ... | 1986 | 3524440 |
| microbial filtrates activate granulocytes without complement or prostaglandins. | cardiorespiratory dysfunction in sepsis may be mediated by circulating complement, activated leukocytes, prostaglandins, or by a direct effect of endotoxin. the purposes of this study were to determine if pathogenic microbes produce these substances and to evaluate the direct effects of substances released by micro-organisms on granulocyte aggregation (ga). escherichia coli, (e. coli), aeromonas hydrophila (aeromonas h.), staphylococcus aureus (s. aureus), and candida albicans, (candida a.) were ... | 1986 | 3524892 |
| thromboxane a2 mediates hemodynamic and respiratory dysfunction in graded bacteremia. | thromboxane a2 has been implicated as a mediator of cardiorespiratory dysfunction in sepsis. this study evaluated whether or not thromboxane a2 was necessary or sufficient for these adverse effects to occur during bacteremia. fourteen adult swine under barbiturate anesthesia and breathing room air were monitored with arterial and pulmonary artery catheters. animals were studied for 4 hours in three groups: group i, graded infusion of 10(9)/ml aeromonas hydrophila; group ii, aeromonas hydrophila ... | 1986 | 3526603 |
| [treatment of neurosurgical bacterial meningitis using the combination of ceftriaxone-fosfomycin]. | 16 patients with bacterial meningitis following a neurosurgical procedure were given a combination of ceftriaxone and fosfomycin. 8 microorganism were isolated: 2 staphylococcus epidermidis, 1 staphylococcus aureus, 1 neisseria meningitidis, 1 streptococcus pneumoniae, 1 haemophilus influenzae, 1 serratia marcescens and 1 aeromonas hydrophila. no pathogen was identified in the remaining cases. all of the isolated strains were susceptible to both antibiotics. in vitro, neither synergy nor antagon ... | 1986 | 3534726 |
| prostacyclin and thromboxane a2 in septic shock: species differences. | prostacyclin and thromboxane a2 have been implicated as mediators of septic shock. correlations between the human prostanoid response to sepsis and experimental paradigms are poorly understood. the purpose of this study was to compare changes in plasma levels of prostaglandin 6-keto-f1 alpha (pgi) and thromboxane b2 (txb) during septic shock in sprague-dawley rats, domestic pigs, mongrel dogs, and man. severe sepsis followed by septic shock (systolic bp less than 90 mmhg) was induced in rats by ... | 1986 | 3539388 |

| in vitro and in vivo study of an antimicrobial activity displayed by the redmouth disease agent, yersinia ruckeri. | a soluble antimicrobial product has been detected in yersinia ruckeri cultures. the contract droplets technique and the double agar layer method allowed to assess its bacteriostatic effect and the high susceptibility of other bacterial fish pathogens like vibrio and aeromonas. but it did not inhibit other strains of y ruckeri. no correlation was found between the antimicrobial activity and the virulence of the strains. as mixed infections with a salmonicida and y ruckeri could be obtained experi ... | 1987 | 3579181 |
| nucleotide sequence of the gene for the hole-forming toxin aerolysin of aeromonas hydrophila. | the gene for the hole-forming toxin aerolysin from aeromonas hydrophila was sequenced. although most of the sequence seems unrelated to that of staphylococcus aureus alpha-toxin, both proteins are very hydrophilic, and they each contain a nearly identical string of 10 amino acids. | 1987 | 3584074 |
| congo red uptake by motile aeromonas species. | virulence of several species of enteropathogenic bacteria has been correlated with the ability of isolates to take up the dye congo red. to determine whether congo red uptake might be a useful marker for virulence of motile aeromonas species, we examined 50 strains of diverse clinical origin on a medium containing 50 micrograms of congo red per ml. all of the strains took up the dye to various degrees. for most strains, uptake was greatest at 37 degrees c and least at 22 degrees c. production of ... | 1987 | 3584422 |
| aeromonas veronii, a new ornithine decarboxylase-positive species that may cause diarrhea. | in 1983, the vernacular name enteric group 77 was coined for a group of strains that had been referred to our laboratory as "possible vibrio cholerae except for gas production." by dna-dna hybridization (hydroxyapatite, 32p), 8 of 10 strains of enteric group 77 were very highly related to the labeled strain 1169-83 (74 to 100% at 60 degrees c and 75 to 100% at 75 degrees c; percent divergence, 0.0 to 2.5). type strains of six other aeromonas species were 45 to 66% related (60 degrees c) to strai ... | 1987 | 3584425 |
| clinical and biochemical significance of toxin production by aeromonas hydrophila. | production of cytotoxin and enterotoxin by aeromonas strains obtained from stools of 50 children in mexico and texas and from blood of 9 children with sepsis was determined. results were correlated with clinical features of infected children as well as with biochemical traits of aeromonas strains. cytotoxin was produced by 40 of 42 aeromonas strains (95%) isolated from stools of children with diarrhea, by all 8 isolates from stools of well children, and by all 9 isolates from children with sepsi ... | 1987 | 3584426 |
| haemagglutination patterns of aeromonas spp. related to species and source of strains. | the study included 138 a. sobria and 182 a. hydrophila isolated in perth from samples of diarrhoeal or non-diarrhoeal faeces or from domestic water. strains were grouped in relation to agglutination of human, horse, rat and guinea pig erythrocytes and the effect of sugars on haemagglutination. agglutination of red cells of all four species (primary group 1) was most commonly associated with a. sobria, particularly those strains isolated from faeces of patients with diarrhoea. most a. hydrophila ... | 1986 | 3593124 |
| a modification of bile salts brilliant green agar for isolation of motile aeromonas from foods and environmental specimens. | aeromonas has recently been recognized as an important enteropathogen. in faecal specimens the organism is readily identified and differentiated from coliforms by the positive oxidase reaction. however, few media have proved useful for foods and environmental specimens. bile salts brilliant green starch agar (bbgs) was studied for this purpose by testing artificially contaminated foods as well as natural potential sources. the results indicate the suitability of the medium for the isolation of a ... | 1987 | 3595749 |
| activities of aeromonas hydrophila hemolysins and their interaction with erythrocyte membranes. | the activity of hemolysin produced by aeromonas hydrophila ca-11, isolated from an environmental source, was more sensitive to temperature than that of hemolysin produced by strain ah-1, isolated from a diarrheal case. ca-11 hemolysin failed to elicit hemolysis below 10 degrees c. immunoblotting analyses showed that both hemolysins formed into oligomers in rabbit erythrocyte membrane even when no hemolysis occurred. suggesting that the binding and the subsequent oligomerization are temperature i ... | 1987 | 3596803 |
| ampicillin-dextrin agar medium for the enumeration of aeromonas species in water by membrane filtration. | published selective media were evaluated for the isolation of aeromonas spp. from environmental samples by membrane filtration. satisfactory recoveries were obtained only with ma agar (rippey & cabelli) and dextrin-fuchsin-sulphite agar (schubert), but neither was sufficiently selective. the positive aspects of these two media were combined in a new medium, ampicillin-dextrin agar. recovery from pure cultures and environmental samples was optimal at an ampicillin concentration of 10 mg/l and inc ... | 1987 | 3597206 |
| hydroxamate-induced spectral perturbations of cobalt aeromonas aminopeptidase. | the absorption spectrum of cobalt(ii)-substituted aeromonas aminopeptidase is markedly perturbed by the presence of equimolar concentrations of d-amino acid hydroxamates and acyl hydroxamates that have previously been shown to be powerful inhibitors of this enzyme (wilkes, s. h., and prescott, j. m. (1983) j. biol. chem. 258, 13517-13521). d-valine hydroxamate produces the most distinctive perturbation, splitting the characteristic 527 nm absorption peak of the cobalt enzyme to form peaks at 564 ... | 1987 | 3597389 |
| [aeromonas hydrophila as an autochthonous causative agent of infectious enteritis in germany]. | aeromonas hydrophila was identified by culture technique in diarrhoeal stools and ascites in a patient of 57 years of age who suffered from known alcoholic cirrhosis and additional acute gastroenteritis. no other pathogens that would produce acute diarrhoea were found. the isolated aeromonas hydrophila strain was characterised by the pathogenic properties known to date as pertaining to this species (formation of haemolysin and enterotoxins). hence it is evident that aeromonas hydrophila occurs i ... | 1987 | 3608836 |
| differentiation of motile and mesophilic aeromonas strains into species by testing for a camp-like factor. | motile and mesophilic aeromonas strains can presumptively be differentiated into species in 18 to 24 h by testing the isolates for the production of a camp-like factor. aeromonas hydrophila strains were positive either aerobically or anaerobically, aeromonas sobria strains were positive only aerobically, and aeromonas caviae strains were always negative. | 1987 | 3611325 |
| pyomyositis and hepatic abscess in association with aeromonas hydrophila sepsis. | this report describes a patient with chronic liver disease in whom aeromonas hydrophila sepsis developed following ingestion of fresh lake water. a hepatic abscess and bilateral calf pyomyositis, an extremely rare and previously fatal complication of a. hydrophila septicemia, subsequently developed. the patient recovered following bilateral fasciotomies and systemic antibiotic therapy with gentamicin and trimethoprim/sulfamethoxazole. no previous survivors of a. hydrophila pyomyositis secondary ... | 1987 | 3618636 |

| detection of fish antibody against protein antigen of aeromonas salmonicida by enzyme-linked immunosorbent assay using biotin-avidin system. | antibody against aeromonas salmonicida was detected in sera from immunised or experimentally infected rainbow trout by enzyme-linked immunosorbent assay (elisa) using the biotin-avidin system. the elisa titre correlated well with the agglutinin titres of the sera, but the elisa was found to be more sensitive than the agglutination test. when the rainbow trout serum was separated by column chromatography, antibody activity (determined by elisa and agglutination test) was detected in the igm fract ... | 1987 | 3628989 |
| bacteriology of the freshwater environment: implications for clinical therapy. | water and animal tissue samples were obtained from sources in tennessee, california, and florida. purified bacterial colonies were isolated and organisms identified. fifty-eight isolates were recovered. twenty-seven gram-negative isolates were identified. gram-positive organisms were of the coryneform group or bacillus species. antibiotic susceptibility testing showed that aeromonas species were relatively resistant to a wide variety of antimicrobials, which included trimethoprim, cefazolin, and ... | 1987 | 3631666 |
| [vibrio and aeromonad sensitivity to the vibriostatic o 129]. | sensitivity of vibrios and aeromonads to vibriostatic o129 (2,4-diamino-6,7-diisopropyl pteridine) was studied. the vibrios and aeromonads were isolated in the ussr. the tests were performed with disks made in the ussr and great britain. the content of the drug in the disks was 10 and 150 micrograms. it was shown that v. cholerae o1 v. cholerae not o1 and v. albensis were highly sensitive to vibriostatic o129 and produced no growth in the presence of either low or high concentrations of the drug ... | 1987 | 3631937 |
| class d tetracycline resistance determinants of r plasmids from the fish pathogens aeromonas hydrophila, edwardsiella tarda, and pasteurella piscicida. | tetracycline resistance determinants of r plasmids from the fish pathogens aeromonas hydrophila, edwardsiella tarda, and pasteurella piscicida were classified as class d by their expression of resistance to tetracycline and minocycline and through their dna structure. | 1987 | 3631946 |
| plasmids and resistance to antimicrobial agents in aeromonas sobria and aeromonas hydrophila clinical isolates. | the antimicrobial susceptibilities of 75 aeromonas isolates were determined by agar dilution. differences in resistance patterns were observed between strains isolated from different geographic locations and between a. sobria and a. hydrophila isolates. multiple resistance was common; however, only one conjugative plasmid was detected. this 110-megadalton plasmid mediated resistance to eight antibiotics. | 1987 | 3631947 |
| aeromonas hydrophila-associated colitis in a male homosexual. | a 37-year-old homosexual man was evaluated for a one-week history of hematochezia. results of a physical examination were remarkable only for grossly bloody stool. sigmoidoscopy to 30 cm showed a friable mucosa compatible with an acute colitis, and a rectal biopsy specimen demonstrated an increased plasma cell infiltrate. stool cultures subsequently yielded aeromonas hydrophila; serum human t-cell lymphotropic virus type iii antibody titer was positive. the patient responded to a course of treat ... | 1987 | 3632156 |
| phenotypic characteristics of aeromonas species isolated from adult humans. | the phenotypic characteristics of 89 aeromonas strains, most of which had been isolated from feces, were examined. eighty-two percent of the isolates could be placed into one of four groups on the basis of five tests. the relationship of these groups to the three motile species of aeromonas (aeromonas caviae, a. hydrophila, and a. sobria) that have been isolated from humans is unclear. because the means for identification of aeromonas strains to the species level appear to be imprecise and becau ... | 1986 | 3635534 |
| typing of aeromonas species by polyacrylamide-gel electrophoresis of radiolabelled cell proteins. | a method for typing species of aeromonas by 35s-labelling and sodium-dodecyl sulphate polyacrylamide-gel electrophoresis (sds-page) of total soluble proteins is described. radiolabelled-protein profiles from different strains were compared by use of the dice coefficient. typability was 100% and discrimination of pairs of differing strains was satisfactory with acceptable reproducibility. the results also yielded information on subgroups of phenotypic species. | 1987 | 3656393 |
