snake-to-human transmission of aeromonas (pl) shigelloides resulting in gastroenteritis.a healthy young man developed acute gastroenteritis after handling an infected bao constrictor. the animal died after contracting "mouth-rot disease", a progressive ulcerative stomatitis of snakes charactistically caused a aeromonas species. stool cultures from the patient yielded a heavy growth of aeromonas (plesiomonas) shigelloides but no other enteric pathogens. treatment wit sulfamethoxazole-trimethoprim resulted in rapid relief of clinical symptoms. aeromonas species are not considered par ...1978635632
effects of fever on host defense mechanisms after infection in the lizard dipsosaurus dorsalis.fever has never been proven beneficial in mammals, although it enhances survival in the lizard d. dorsalis infected with aeromonas hydrophila. we examined the course of the infection and the function of host defence in febrile (41 degrees) and afebrile (35 degrees or 38 degrees) animals using this model. infected, febrile lizards had sterile blood cultures, and 1-2 logs fewer bacteria in body tissues 6-12 h after infection. granulocytes appeared early and in large numbers at the site of inoculat ...1978638032
carbenicillin plus cefamandole in the treatment of infections in patients with cancer.the combination of carbenicillin plus cefamandole was administered to 88 patients with cancer during 116 evaluable episodes of fever. the overall response rate to carbenicillin plus cefamandole for the 116 episodes was 57%. there were 60 documented infections, of which 60% responded to this combination of antibiotics. the response rate was only 43% in patients with pneumonia. the etiologic agent was identified during 38 infections, of which 74% responded to carbenicillin plus cefamandole. respon ...1978649998
fatal aeromonas hydrophila infection of the skin.a 62-year-old woman developed a fatal aeromonas hydrophila infection of the skin after dropping a crab trap on her leg. the area surrounding the punctures was erythematous and had several flaccid bullae. a biopsy specimen of the involved skin showed necrosis and suppuration in the dermis and subcutaneous fat. the a hydrophila sepsis resolved after treatment with gentamicin, but the patient developed secondary wound infections and died three months after injury.1978663710
a bacterial disease of the darwin's frog (rhinoderma darwini).ulceration and necrosis of the rostrum in darwin's frogs was investigated microbiologically and histopathologically. the condition was attributed to infection with aeromonas liquefaciens and, possibly, an acinetobacter sp.1978672182
fever and survival: the role of serum iron.1. the effects of bacterial infection and temperature on serum iron levels were investigated in the lizard dipsosaurus dorsalis. 2. changes in body temperature from normal (38 degrees c) to febrile (41 degrees c) did not alter serum iron levels. injection with aeromonas hydrophila led to a significant reduction in serum iron levels, comparable to that found in mammals. this reduction in serum iron level was independent of the lizard's body temperature. 3. when grown in vitro, a. hydrophila grew ...1978678329
lipopolysaccharides of the motile aeromonads; core oligosaccharide analysis as an aid to taxonomic classification.twelve motile aeromonas strains have been examined with respect to the hexose and heptose monosaccharide residures present in the core region of their cell wall lipopolysaccharides. these strains were divided into three distinctly separate groups on the basis of the various combinations of hexose and heptose residues. the assignment of a strain to any one of the three groups furnishes a distribution which is substantially the same as that recently reported in a computerbased numerical analysis. ...1978679071
presence of glycerophospholipid: cholesterol acyltransferase and phospholipase in culture supernatant of aeromonas hydrophila.human erythrocyte membrane glycerophospholipids are deacylated by aeromonas hydrophila 13-h culture supernatants, resulting in the production of cholesterol ester, free fatty acid, and water-soluble phosphates. this activity appears to be due to the actions of an acyltransferase (phosphatide:cholesterol acyltransferase, ec 2.3.1 group) and a phospholipase (phosphatide acyl-hydrolase). the enzyme activities are produced simultaneously in late exponential/early stationary phase, are precipitated t ...1978681278

neuraminidase activity of nag vibrios and of some representatives of the intestinal group of bacteria.it was studied 203 strains of nag vibrios and 71 strains of different enterobacteria for the ability to produce neuraminidase. the most frequent neuraminidase producers were found among the strains isolated from humans (99 strain of 131). there was no correlation between neuraminidase production and other properties of the vibrios. the examined strains of the family enterobacteriaceae did not produce the enzyme.1978744553
[drinking waters and drug resistant bacteria. implications for water quality standards (author's transl)].a systematic investigation of antibiotic sensibility has been carried out on 1,000 strains of enterobacteria and aeromonas isolated from drinking water. 81,6% are resistant to one or more antibiotics. the incidence of this resistance and its epidemiological consequences are discussed.1978749057
diseases of chelonians: (2) necropsy survey of terrapins and turtles.a total of 122 terrapins (freshwater chelonians) of 36 species and seven turtles (marine chelonians) represented by three species, all of which had died in captivity, were necropsied. in terrapins, bacterial infections were a common cause of death (15.5 per cent). although salmonella infections appear to be less common in great britain than in the usa, terrapins are a potentially important source of infection to humans. fungal infections amounted to only 3.3 per cent. nutritional disorders, espe ...1978749320
effect of arginine analogues on a fish pathogen, aeromonas salmonicida.the effects of arginine analogues on a fish pathogen, aeromonas salmonicida, were investigated. this organism proved to be resistant in various degrees to most arginine analogues tested but was found to be sensitive to arginine hydroxamate. inhibition of growth by arginine hydroxamate was reversed by the addition of arginine to the bacterial culture. incorporation of 14c from 14c-amino acids, namely, guanidoarginine, glutamate, asparate, alanine, isoleucine, serine, methyl-methionine, and cystin ...1978756951
on arginine splitting as a taxonomic criterion with special regard to the separation of aeromonas and vibrio.an investigation of various methods and media intended for arginine testing of aeromonas or vibrio, showed that the method of thornley (1960) was superior to the others for this purpose because it showed the best conformity with the established taxonomy of a number of type strains and because it furthermore yielded the lowest percentage of false positive reactions from a number of aeromonas/vibrio-suspect strains of marine origin.1978343065
human aeromonas infections: a review of the literature and a case report of endocarditis.our patient, with cirrhosis and chronic renal failure, represents an example of the susceptibility of a compromised host to aeromonas infections. this patient, however, differs from previously reported cases in at least two important aspects. first, it is possible that her portal of entry was a fresh a-v fistula puncture site rather than an intestinal site. the temporal relationship of exposure to flood water prior to the onset of sepsis lends support to this possibility. epidemiologic investiga ...1978347223
differences between cephalothin and newer parenterally absorbed cephalosporins in vitro: a justification for separate disks.the activities of cefamandole and cefoxitin in vitro were compared with that of cephalothin against staphylococci and gram-negative bacilli. cephalothin was the most active agent against staphylococci. cefamandole exhibited the greatest activity against the enterobacteriaceae, with the exceptions of serratia marcescens and indole-positive proteeae, against which cefoxitin was the most active antibiotic. the activity of newer cephalosporins that are resistant to the beta-lactamases of gram-negati ...1978349096
[occurrence of r plasmids belonging to incompatibility group incc in aeromonas hydrophila strains isolated from sewage water (author's transl)].the susceptibility to antimicrobial agents of 321 strains of aeromonas hydrophila was studied: 319 strains were found to be resistant to one or several antibiotics. transfer of resistance markers was obtained from 24 strains. five plasmids from these strains were classified into incompatibility group incc. epidemiological consequences of r plasmid diffusion in water bacteria are discussed.1978363014

ultrastruct of red-sore lesions on largemouth bass (micropterus salmoides): associattion of the ciliate epistylis sp. and the bacterium aeromonas hydrophila.epizootic outbreaks of red-sore disease in several reservoirs in the southeastern united states have been reported to cause heavy mortality among several species of fish having sport and commercial value. the etiologic agent is said to be the peritrich ciliate epistylis sp.; secondary infection by the gram-negative bacterium aeromonas hydrophila produces hemorrhagic septicemia which results in death. however, in recent studies on the largemouth bass micropterus salmoides, epistylis sp. could be ...1978102785
diseases of chelonians: (1) necropsy survey of tortoises.the results of necropsies of 144 tortoises of 17 species that died in captivity are presented. intestinal and nutritional disorders (27.0 and 22.2 per cent respectively) were the most common causes of death. nematode infestations were found in 43.8 per cent, but with exception of a few species the parasites were seldom pathogenic. infestations with other helminths appear to be very unusual. protozoan infections were relatively common (at least 22.9 per cent) but protozoa are probably seldom path ...1978105454
bacterial 2,3-butanediol dehydrogenases.enterobacter aerogenes, aeromonas hydrophila, serratia marcescens and staphylococcus aureus possessing l(+)-butanediol dehydrogenase produced mainly meso-butanediol and small amounts of optically active butanediol; acetobacter suboxydans, bacillus polymyxa and erwinia carotovora containing d(-)-butanediol dehydrogenase produced more optically active butanediol than meso-butanediol. resting and growing cells of these organisms oxidezed only one enantiomer of racemic butanediol. the d(-)-butanedio ...197825056
studies of relationship among terrestrial pseudomonas, alcaligenes, and enterobacteria by an immunological comparison of glutamine synthetase.antibody to purified glutamine synthetase from escherichia coli was prepared and used for an immunological comparison of glutamine synthetases from species of salmonella, citrobacter, enterobacter, serratia, proteus, erwinia, aeromonas, pseudomonas, acinetobacter, xanthomonas, alcaligenes, and paracoccus. the results of ouchterlony double diffusion experiments and quantitative microcomplement fixation studies indicated that the amino acid sequence of this enzyme was highly conserved in different ...197831146
prevalence and distribution of aeromonas hydrophila in the united states.the abundance of aeromonas hydrophila was measured in 147 natural aquatic habitats in 30 states and puerto rico. viable cell counts were used to estimate density at all sites by using rimler-shotts medium, a differential presumptive medium for a. hydrophila. temperature, ph, conductivity, salinity, and turbidity were measured simultaneously with water sample collection. the density of a. hydrophila was higher in lotic than in lentic systems. saline systems had higher densities of a. hydrophila t ...197831839
precipitate produced by serratia marcescens on macconkey agar: useful diagnostic test.the production of a precipitate by serratia marcescens on oxoid macconkey agar has proven useful as a laboratory diagnostic test. this phenomenon is specific for serratia within the enterobacteriaceae, although precipitate production is also given by acinetobacter anitratus and some pseudomonas, alcaligenes, and aeromonas species. precipitate production seems to be specific for certain batches of macconkey agar, and is probably related to a specific property of some batches of bile salts.197832188
enterotoxicity of aeromonas hydrophila: skin responses and in vivo neutralisation.culture filtrates and partially purified enterotoxins of 6 strains of aeromonas hydrophila isolated from faeces of diarrhoeic and healthy persons, drinking water, sewage and faeces of domestic animals caused induration and increased capillary permeability in skin of adult albino rabbits. the activities were less in crude enterotoxins indicating partial loss during purification. heat treatment for 30 min at 60 degrees c and 56 degrees c inactivated the induration and permeability effects of cultu ...197834953
characterisation and neutralisation of aeromonas hydrophila enterotoxin in the rabbit ileal-loop model.cell-free culture filtrates and crude enterotoxin preparations from six strains of aeromonas hydrophila caused the accumulation of fluid in rabbit ileal loops. this activity was due to a non-dialysable, heat and acid-labile antigenic protein and was lost when culture filtrates and crude enterotoxin preparations were heated at 60 degrees c for 20 min. or 56 degrees c for 30 min. respectively. maximum activity was observed at ph 8.0-10.0; there was a gradual loss at lower ph and activity was aboli ...197938341
biosynthesis of ethylene from methionine. isolation of the putative intermediate 4-methylthio-2-oxobutanoate from culture fluids of bacteria and fungi.methods are described for identifying the 2,4-dinitrophenylhydrazones of 4-methylthio-2-oxobutanoate by means of t.l.c., n.m.r. and mass spectroscopy. by using these methods 4-methylthio-2-oxobutanoate, a putative intermediate in the biosynthesis of ethylene from methionine, has been identified in culture fluids of aeromonas hydrophila b12e and a coryneform bacterium d7f grown in the presence of methionine. relative to 4-methylthio-2-oxobutanoate, the yield of 3-(methylthio)propanal (methional) ...197942392
[bacteriological studies of the intestinal content of aquatic birds, fishes, and frogs with special reference to the presence of non-cholera vibrios (ncv) (author's transl)].in a screening study of surface waters, the authors were successful in culturing ncv in 2/3 of cases. since these organisms are incapable of multiplication in open waters and yet were present in water samples in considerable amounts, it was postulated that they persisted in certain forms of aquatic life. to elucidate this question, the intestinal contents and in some cases, the bile of a total of 110 animals belonging to 17 different bird, fish, and frog species from different habitata were exam ...197944627

evidence for the subcellular localization and specificity of chlordane inhibition in the marine bacterium aeromonas proteolytica.sublethal levels (10 to 100 micrograms/ml) of the chlorinated insecticide chlordane (1,2,4,5,6,7,8,8-octachloro-3a,4,7,7a-tetrahydro-4,7-methanoindan) were introduced into the growth medium of the marine bacterium, aeromonas proteolytica. chlordane inhibited the synthesis of an extracellular endopeptidase by almost 40% but exhibited no such inhibition of the extracellular aminopeptidase also produced during the growth cycle. studied with 14c-labeled chlordane demonstrated that the insecticide wa ...1979156517
differential toxicities of mercury to bacteria and bacteriophages in sea and in lake water.mixtures of anionic hgcl3-/hgcl4(2)-complexes were less toxic to terrestrial bacteria (erwinia herbicola, agrobacterium tumefaciens), to marine bacteria (acinetobacter sp., aeromonas sp.), and to bacteriophages (phi 11 m 15 of staphylococcus aureus and p1 of escherichia coli) than were equivalent concentrations of hg as cationic hg2+. the toxicity of 1 ppm hg to a. tumefaciens. aeromonas sp., and phi 11 m 15 was less in seawater than in lake water. inasmuch as the hg-cl species are formed in env ...1979161510
the variable response of bacteria to excess ferric iron in host tissues.the enhancement by exogenous ferric iron, both systemic and local, of the infectivity of 120 strains of bacteria, representing 17 genera, was measured in the skin of guinea-pigs. systemic iron enhanced only 23% of 115 strains, and local iron 49% of 71 strains. systemic iron, by an apparently anti-inflammatory action, depressed the size of lesions produced by 27 of the non-enhanced strains from nine of the genera tested. for most strains, the degree of enhancement was small, ranging from 2- to 8- ...1979372534
clinical involvement of aeromonas hydrophila.aeromonas hydrophila has for some time been regarded as an opportunistic pathogen in hosts with impaired local or general defence mechanisms. infections in such individuals are generally severe. the organism is also being isolated with increasing frequency throughout the world from a variety of focal and systemic infections of varying severity in persons that are apparently immunologically normal. most commonly it causes acute diarrheal disease by producing an enterotoxin. thus the organism appe ...1979373876

[activity of antibiotics and heavy metals against "aeromonas" isolated from aquatic environments: phenotypic and genetic transfers (author's transl)].in this study, 64% of the 197 strains of aeromonas isolated from different stages of aquatic environment (surface water, sewage...) were resistant to one or two antibiotics, and 20% to four or more antibiotics. these multiresistant strains were only isolated from sewage and their resistances were transferable by conjugation to different species of gram-negative bacilli. the incidence of these results is discussed.1979533074
furunculosis of salmonids: vaccination attempts in rainbow trout (salmo gairdneri) by formalin-killed germs.two immunization trials were performed in rainbow trout, using a formalin killed aeromonas salmonicida suspension. in the first experiment, 200 g fish were administered orally or intraperitoneally. circulating antibodies were elicited in injected animals only, but no protection was found when they were challenged with a highly virulent strain. rough and smooth bacteria have provided similar agglutinins titers. in the second study, fingerlings were vaccinated by injection, but experimental diseas ...1979539775
bacterial flora of the schistosome vector snail biomphalaria glabrata.the aerobic heterotrophic bacterial flora in over 200 individuals from 10 wild populations and 3 laboratory colonies of the schistosome vector snail biomphalaria glabrata was examined. internal bacterial densities were inversely proportional to snail size and were higher in stressed and laboratory-reared snails. the numerically predominant bacterial genera in individual snails included pseudomonas, acinetobacter, aeromonas, vibrio, and several members of the enterobacteriaceae. enterobacteriacea ...1979539821

medium for the presumptive identification of aeromonas hydrophila and enterobacteriaceae.a medium was devised for the rapid presumptive identification of aeromonas hydrophila. it also offered good differentiation of klebsiella, proteus, and other enteric species. mannitol fermentation, inositol fermentation, ornithine decarboxylation and deamination, indole production, motility, and h2s production from sodium thiosulfate and cysteine could be recorded in a single tube of the medium.1979543697
rainbow trout complement fixation used for titration of antibodies against several pathogens.since it is impossible to fix guinea pig complement (c) with rainbow trout (salmo gairdneri) antibodies, whereas it is possible with brown trout (salmo trutta) antibodies, a c fixation test has been designed which uses haemolysin and c from rainbow trout. immunization of trout against lysed sheep red blood cells (srbc) elicited production of haemolytic igm. normal trout serum (nts) can be used as a source of c at a dilution at which its "natural" haemolytic activity (against various homeotherms ...1979547824

growth of aeromonas hydrophila at low concentrations of substrates added to tap water.the ability of an aeromonas hydrophila isolate obtained from filtered river water to grow at low substrate concentrations was studied in batch experiments with tap water supplied with low concentrations of substrates. growth was assessed by colony count determinations. the isolate only multiplied in the used tap water (2 to 3 mg of dissolved organic carbon per liter) after the addition of a small amount of an assimilable carbon compound. d-glucose especially caused growth of the organism even at ...198016345582
hemagglutination properties and adherence ability of aeromonas hydrophila.human diarrheal isolates and enterotoxigenic strains of aeromonas hydrophila are strong hemagglutinators with human blood cells. sugar inhibition studies and yeast coagglutination tests with 11 selected strains revealed six different hemagglutination mechanisms for this species. these were characterized by inhibition by l-fucose, inhibition by d-galactose, inhibition by d-mannose, and two distinguishable mechanisms which were inhibited by either l-fucose or d-mannose, one being pilus mediated. i ...19806103874
distribution and characterization of kepone-resistant bacteria in the aquatic environment.effects of the chlorinated insecticide kepone on the ecology of chesapeake bay and james river bacteria were studied. kepone-resistant bacteria present in a given environment were found to reflect the degree of fecal and/or high organic pollution of the sampling sites, based on total numbers and generic composition of the populations of kepone-resistant bacteria. the presence of kepone-resistant bacteria was found to be correlated (alpha = 0.01) with total coliforms, fecal coliforms, and total a ...19806155825
