fever and antipyresis in the lizard dipsosaurus dorsalis.lizards (dipsosaurus dorsalis) were placed in a desertlike environment in which the ambient temperature (ta) at night (1800-0600 h) was 12 degrees c and the day (0600-1800 h) ta was between 30 and 55 degrees c depending on the location within the chamber. when dead aeromonas hydrophila (4 x 10(9) organisms) was injected into nine lizards, an elevation in body temperature (tb) of 2.7 degrees c was observed during the same day. on the day after bacterial injection the lizards' body temperatures av ...1976961860
effect of aeromonas salmonicida (furunculosis) infection on the incorporation of [1-14c]acetate into lipids of trout liver.[1-(14)c]acetate is incorporated into lipids more rapidly by liver from aeromonas salmonicida-infected trout than by normal trout liver, both in vitro and in vivo. the increase was, in general, about twofold to less than threefold.1976965100
ultrastructural examination of aeromonas cultured in the presence of organic lead.aeromonas sp. will methylate trimethyl lead acetate (me3pboac) to volatile tetramethyl lead (me4pb). examination of cultures grown in the presence of me3pboac revealed no major irregularities between cells of the treated and untreated cultures. some cells, however, showed evidence that intracytoplasmic materials had been leached from the cells. the lead-treated cells were interpreted to contain lead ions on the basis of energy-dispersive x-ray analysis.1976984840
[taxonomic importance of fermentation balances of enterobacteriaceae (author's transl)].fermentation balances have been studied on 66 strains from 9 taxa of enterobacteriaceae. in addition, 6 strains of aeromonas have been investigated. among these fermentation balances, 7 types could be distinguished. it was shown, that the taxa of enterobacteriaceae differed with respect to the balance types involved. this is true especially for vp-positive taxa. for example, hafnia, the klebsiella-enterobacter-serratia group, enterobacter cloacae and erwinia are to some extend characterized by d ...1976998036
enterotoxin-producing bacteria and parasites in stools of ethiopian children with diarrhoeal disease.enterotoxinogenic bacteria were isolated from 131 (37%) of 354 ethiopian infants and children with acute gastrointestinal symptoms. only one of these isolates belonged to the classical enteropathogenic serotypes of esch. coli. two colonies from each patient were isolated and tested for production of enterotoxin by the rabbit ileal loop test, the rabbit skin test, and an adrenal cell assay. however, only 38% of the isolated enterotoxinogenic strains were esch. coli; the others belonged to klebsie ...19761008593

[production of anti-aeromonas salmonicida agglutinins by the rainbow trout. influence of temperature, an adjuvant and an immunosuppressive agent].adult rainbow trout were immunized intraperitoneally with a chloroform killed aeromonas salmonicida suspension. agglutinating antibodies were titrated using a microtiter system. antibody activity was associated with igm fraction obtained from sepharose 4 b gel filtration. the kinetics of antibody formation were established at three temperatures. at 50c detectable antibodies were found at day 50 post immunization. at 10degrees c and 16 degrees c the agglutinin titer rose before day 20. the antibo ...19761028376

antibiotic sensitivity of two aeromonas and nine pseudomonas agar dilution method was used to determine the in vitro sensitivity of different pseudomonas and aeromonas species to sulphonamide, tetracycline, colistin, gentamicin, tobramycin, amplicillin, carbenicillin, and cephalothin. p. aeruginosa was generally sensitive to carbenicillin, colistin, tobramycin, and gentamicin. p. putida and p. fluorescens were generally resistant to beta-lactam antibodies but sensitive to gentamicin and tobramycin. p. cepacia and p. maltophilia were mostly resistant to ...19751040755
inducible oxacillin-hydrolyzing penicillinase in aeromonas hydrophila isolated from inducible penicillinase was shown to be present in a strain of aeromonas hydrophila subsp. hydrophila isolated from freshwater fish. enzyme induction was observed with benzylpenicillin or 6-aminopenicillanic acid, and the enzyme was cell bound. the penicillinase was purified 50-fold from a crude cell extract. the molecular weight was estimated to be 23,000 by gel filtration. the ph and temperature optima for the enzyme activity were 8.0 and 35 degrees c, respectively. the penicillinase showed ...19761049517
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
