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

sources of the slow-growing pigmented water bacteria.the group of organisms often labelled as "slow-growing pigmented water bacteria" may include various species of the xanthomonas, cytophoga, pseudomonas, aeromonas and flavobacterium genera. due to their slow growth, this group is usually overlooked in the average clinical laboratory since the pigmented colonies are most easily noted on membrane filter pads or on surface streaked agar plates, but only after 5-15 days of incubation at room temperature. although present at low levels in free-flowin ...1976816754
superactivation of neutral proteases: acylation with n-hydroxysuccinimide esters.a series n-hydroxysuccinimide esters of acylamino acids previously shown to acylate and thereby increase the activity of thermolysin by several orders of magnitude (blumberg, s., and vallee, b. l. (1975), biochemistry 14, 2410) has been used to modify the related neutral proteases from bacillus subtilis, bacillus megaterium, and aeromonas proteolytica. each of these enzymes is activated to a level characteristic of the particular protein and the particular acyl group incorpporated when monitored ...1976823965
interaction of pseudomonas and enterobacteriaceae plasmids in aeromonas salmonicida.we observed that aeromonas salmonicida aro200 will maintain either or both the pseudomonas r-factor, pmg1, and enterobacteriaceae r-factors. this bacterial strain, therefore, provides a unique background wherein the host ranges of pseudomonas and enterobacteriaceae plasmods overlap. co-maintenance of these plasmids resulted in behavior of plasmid aggregates that allowed transfer of r-dterminants beyond the host range of the parent plasmid. we observed that the aro200 genetic background facilitat ...1976824271

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

antibiotic sensitivity of two aeromonas and nine pseudomonas species.an 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 fish.an 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
