kell blood group activity of gram-negative bacteria.to understand better the relationships between blood-group antigens and bacterial constituents, examples of 23 gram-negative bacteria (representing the 10 genera citrobacter, edwardsiella, enterobacter, escherichia, klebsiella, proteus, pseudomonas, salmonella, serratia, and shigella) were tested for the presence of kl-like antigens by hemagglutination-inhibition (hai) assays against both igg and igm anti-kl. saline-suspended whole organisms, cell-free culture media, and disrupted organisms were ...19883368935
the phylogenetic origin of the bifunctional tyrosine-pathway protein in the enteric lineage of bacteria.because bifunctional enzymes are distinctive and highly conserved products of relatively infrequent gene-fusion events, they are particularly useful markers to identify clusters of organisms at different hierarchical levels of a phylogenetic tree. within the subdivision of gram-negative bacteria known as superfamily b, there are two distinctive types of tyrosine-pathway dehydrogenases: (1) a broad-specificity dehydrogenase (recently termed cyclohexadienyl dehydrogenase [cdh]) that can utilize ei ...19883386529

effect of water temperature on the clinical outcome of infection with edwardsiella ictaluri in channel catfish.channel catfish fingerlings (mean body weight, 19 +/- 3 g each) were given intraperitoneal inoculations of edwardsiella ictaluri suspensions of 10(4), 10(5), or 10(6) bacteria. control fish were inoculated intraperitoneally with sterile 0.85% nacl solution. ten-day trials were conducted at water temperatures of 17, 21, 23, 25, 28, and 32 c. differences in mortality between e ictaluri-infected fish and fish used as controls were observed at water temperatures of 23, 25, and 28 c, but not at tempe ...19873692982
antimicrobial susceptibility of edwardsiella ictaluri.edwardsiella ictaluri isolates collected over the past 7 yr from outbreaks of disease in fish occurring in different geographic areas were screened against 37 antimicrobial agents. edwardsiella ictaluri were found to be susceptible to most agents active against gram negative bacteria such as aminoglycosides, cephalosporins, the "newer" penicillins, quinolones, tetracyclines, chloramphenicol, nitrofurantoin, and potentiated sulfonamides. resistance was observed against colistin, sulfonamides, and ...19863712643
salmonellae and other enteropathogenic bacteria in the intestines of wall geckos in nigeria.the aerobic bacterial flora of the intestine of 150 wall geckos (hemidactylus brookei) was investigated. a variety of bacteria was recovered including 35 isolates of salmonella and several other species of enterobacteriaceae, viz. shigella sonnei - 2, edwardsiella tarda - 4, enterobacter spp - 8, citrobacter freudii - 3, serratia marcescens - 3, proteus spp - 35, klebsiella pneumoniae - 13, and escherichia coli - 17, isolates. eight salmonella serotypes were identified, the predominant ones bein ...19863729372
modulary effects of temperature on antibody response and specific resistance to challenge of channel catfish, ictalurus punctatus, immunized against edwardsiella ictaluri.the effects of various temperature treatments on the level of the humoral antibody response in channel catfish immunized with formalin killed edwardsiella ictaluri was determined in laboratory controlled experiments. immunized fish that were held at 25 degrees c for 30 days and 12 degrees c for an additional 30 days had higher antibody titers, and were more protected upon challenge, than immunized fish held at 25 degrees c for 60 days. also immunized catfish held at 25 degrees c for 5 or 10 days ...19863765350
antimicrobial susceptibility of edwardsiella tarda from the united states and taiwan.edwardsiella tarda isolates from the united states and taiwan were screened against 37 antimicrobial agents. these isolates were highly susceptible to the amino-glycosides, second and third generation cephalosporins, newer penicillins, nitrofurantoin, sulfamethoxazole/trimethoprim, and the quinolones. source-related resistance was found for penicillin g, sulfadiazine, colistin, novobiocin, spectinomycin, ampicillin, tetracycline, and chloramphenicol. generally, the taiwan isolates were more resi ...19863776095

disease patterns in the detroit zoo: a study of reptilian and amphibian populations from 1973 through 1983.a retrospective study was conducted to determine disease patterns in reptilian and amphibian populations at the detroit zoo from 1973 through 1983. in the reptilian population (mean +/- sd = 285.2 +/- 28), overall annual mortality rates were 1% to 40%. mortality rates were highest in the fall months (20%) and lowest in the winter months (6%). the most frequently affected reptiles were iguana (iguana iguana), reticulated python (python reticulatus), rattlesnakes (crotalus spp), common boa (constr ...19853878352
liver abscess caused by edwardsiella tarda.edwardsiella tarda, among other enterobacteriaceae, is a rare isolate from clinical specimens in man. a liver abscess caused by e. tarda was found in a middleaged woman without overt epidemiologic exposure to known reservoirs of this organism. while the most likely source of infection was the bowel, we failed to demonstrate a gut carriage of e. tarda or to show any local condition predisposing to the development of the liver lesion.19853911993
biochemical characteristics of edwardsiella ictaluri.a total of 119 isolates of edwardsiella ictaluri collected over the last 7 years from several states were biochemically characterized. although not very reactive biochemically, this bacterium shows a high degree of homogeneity. differences were found only in the production of gas from formate or from glucose at 37 degrees c and in the production of hydrogen sulfide as detected by lead acetate paper. analysis of e. ictaluri by year of geographic area indicated that some differences existed, but n ...19863954336
rapid microbiochemical method for presumptive identification of gastroenteritis-associated members of the family enterobacteriaceae.a method for rapid screening of isolates of pathogenic members of the family enterobacteriaceae is described. flow charts are used in conjunction with triple sugar iron agar, o-nitrophenyl-beta-d-galactopyranoside-phenylalanine-motility sulfate screening media, oxidase test, and six rapid biochemical tests, namely, lysine decarboxylase, urease, indole, esculin hydrolysis, malonate, and xylose. this scheme is used to provide an inexpensive but rapid presumptive identification of salmonella, shige ...19854008622
chemiluminescence by peripheral blood phagocytes from channel catfish: function of opsonin and temperature.the ability of the peripheral blood phagocytes from channel catfish, ictalurus punctatus, to produce chemiluminescence (cl) following ingestion of the enteric pathogen edwardsiella ictaluri was evaluated under a variety of opsonic and temperature conditions. the cl response was influenced by the concentration of immune serum used to opsonize the bacteria as well as the presence of nonspecific, heat labile opsonins. peak light emissions were diminished and the time to peak response was increased ...19854018342
comparative in vitro activities of selected antimicrobial agents against edwardsiella tarda.mics of 14 antimicrobial agents for 29 strains of edwardsiella tarda were determined by an agar dilution method. of the agents tested, ciprofloxacin, enoxacin, and norfloxacin were the most active on a weight basis. all strains were also susceptible to clinically achievable concentrations of ampicillin, chloramphenicol, tetracycline, trimethoprim, sulfamethoxazole, trimethoprim plus sulfamethoxazole, cefotaxime, and gentamicin. ninety percent of the strains demonstrated high-level resistance to ...19854026271
