isolation and identification of aeromonas hydrophila from an outbreak of haemorrhagic septicemia in snakes.aeromonas hydrophila was isolated during an outbreak of a fatal disease among snakes kept in the serpentarium of the razi institute. the organism was identified on the basis of morphological and biochemical properties, as well as pathogenicity for both warm blood and poikilothermic animals.19734270815

identification of vibrio cholerae by pyrolysis gas-liquid chromatography.cholera-like vibrios examined by pyrolysis gas-liquid chromatography could be distinguished from other common aerobic gram-negative bacilli, including oxidase-positive organisms, e.g., aeromonas. vibrios in heiberg group i were subdivided into three types on the basis of differences in one complex in the chromatogram, and these closely corresponded with the identification as classical, el tor, or "intermediate" biotypes of vibrio cholerae by conventional methods.19734346977

recurrent aeromonas sepsis in a patient with leukemia.a case of recurrent sepsis due to aeromonas hydrophila in a patient with acute myelogenous leukemia is reported. the patient's first infection leading to bacteremia followed contamination of a mosquito bite by stagnant water. after recovery from the first bacteremia, the patient again became septic with a second strain of aeromonas hydrophila, which again responded to antimicrobial therapy. it is hypothesized that contamination of the local water supply may have led to the establishment of a gas ...19751060378
[the methylene-blue-reduction-test (mr-test) and the micro-ttc-test for the determination of substances as sole source of carbon in the taxonomy of pseudomonas species (author's transl)].two methods are described for the determination of substances as sole source of carbon for taxonomic tools: the methylene-blue-reduction-test and the micro-ttc-test. both methods are giving results superior to the technique introduced by stanier and co-workers and used hitherto in the taxonomic classification of pseudomonas species. the evaluation of the comparative test results is based on the criterion that a substance is useful for taxonomic purpose provided that at least 90 per cent of the s ...197551553

interactions between aerolysin, erythrocytes, and erythrocyte membranes.aerolysin, a hemolytic and lethal exotoxin of aeromonas hydrophila, was analyzed for amino acids. assuming 8 histidine residues/mol, the purified toxic protein has, by summation, a molecular weight of 49,000, a value in agreement with earlier estimates by other methods. erythrocytes from different animal species differ greatly in sensitivity to aerolysin's lytic action. there is some correlation between sensitivity and phosphatidyl choline content. erythrocyte membranes of different species bind ...1975166917

[aeromonas punctata subsp. caviae as the causative agent of acute gastroenteritis (author's transl)].since in the past, aeromonas hydrophila had been isolated from all cases of human infection described. a. punctata and the anaerogenic sub-species were considered as apathogenic. from the case described, a close association between acute diarrhea with vomiting and the identification of a. punctata subsp. caviae becomes evident so that a conditional pathogenicity of this sub-species must be assumed. the question is discussed whether a preceding disturbance of the intestinal habitat in the presenc ...1975175615

fever and survival.the significance of fever in response to a bacterial infection has been investigated using the lizard dipsosaurus dorsalis as an animal model. these lizards develop a fever of about 2 degrees c after injection with the bacterium aeromonas hydrophila. to determine whether this elevation in body temperature increases the resistance of the host to this infection, as measured by survival, lizards were infected with the live bacteria and placed in a neutral (38 degrees c), low (34 degrees or 36 degre ...19751114347
a cluster analysis of some bacteria in the water column of green lake, washington.mass inoculation and computer clustering techniques were used in an abbreviated procedure to group similar bacteria isolated from four depths in the water column of green lake, washington. four groups of bacteria were differentiable and were catagorized as orange-yellow flavobacterium-cytophaga, yellow flavobacterium-cytophaga, vibrio-aeromonas-, and pseudomonas-like. some of the groups were most prevalent in certain sample depths in the water column.19751116047
