| invasiveness of aeromonas spp. in relation to biotype, virulence factors, and clinical features. | of 69 fecal isolates of aeromonas spp., 18 had the ability to invade hep-2 cells. invasiveness correlated with biotype; of the 18 invasive strains, 16 were a. sobria and 2 were a. hydrophila. no invasive strains were found among the a. caviae. of the 18 invasive strains, 13 were enterotoxigenic. of the enterotoxigenic and invasive strains, 12 were a. sobria, but enterotoxicity was also more common among noninvasive strains of a. sobria. fucose-resistant hemagglutination was also more common in a ... | 1985 | 4019741 |
| the antagonism of tetracycline and ferric iron in vivo. | to test the hypothesis that the in-vivo antibiotic action of tetracycline might be affected by ferric iron and the enhancement of infection by ferric iron by tetracycline, the actions of intraperitoneal antibiotic and local ferric ammonium citrate, given separately and together, were measured in the dorsal skin of guinea-pigs bearing lesions due to staphylococci, streptococci, a proteus sp., an erysipelothrix sp., clostridium perfringens, pseudomonas aeruginosa, aeromonas hydrophila and klebsiel ... | 1985 | 4020849 |
| bacteremia caused by aeromonas species in hospitalized cancer patients. | bacteremia caused by aeromonas species occurred in 24 hospitalized patients in a cancer institute during a 13-year period. all but one of these patients had a malignancy (88% had leukemia), and most were receiving chemotherapy for cancer. there was a striking numerical predominance of male patients (82%). unlike some previously described patients with infections due to this organism, none of these 24 patients had recently been exposed to fresh or salt water or to fish. the source of the infectin ... | 1985 | 4023526 |
| a transition-state-analog inhibitor influences zinc-binding by aeromonas aminopeptidase. | the transition-state-analog inhibitor, 1-butaneboronic acid, markedly enhances the uptake of one g-atom of zn2+ ions from a metal ion buffer system by zn-depleted aeromonas aminopeptidase. in contrast, a substrate-analog inhibitor, n-valeramide, does not perturb the equilibrium between zn2+ ions and the enzyme in a metal ion buffer system. these results establish a role for metal ions in the binding of 1-butaneboronic acid to aeromonas amino-peptidase and strongly imply that a bound zn2+ ion int ... | 1985 | 4026862 |
| salmonellae and pollution indicator bacteria in municipal and food processing effluents and the cornwallis river. | a study was conducted to determine the incidence of fecal coliforms, fecal streptococci, aeromonas hydrophilia, and salmonella spp. in the waste discharges of seven sewage treatment plants, four fruit and vegetable canneries, a meat packing plant, a poultry processing plant, and a potato processing plant located along the cornwallis river in nova scotia, canada. surface water samples were also collected from 13 locations in the river to assess the impact of these waste discharges on the receivin ... | 1985 | 4027779 |
| bacteria in bivalve shellfish with special reference to the oyster. | the bacterial flora of the pacific oyster crassostrea gigas, the sea mussel perna viridis and the arkshell clam scapharca cornea differed considerably from that of seawater in both numbers and generic composition. the numbers of heterotrophic bacteria in the bivalve shellfish, including the anaerobes and spore-forming bacteria, were greater than that in the surrounding water. pseudomonas spp. were the dominant organisms, comprising over one third of the 321 strains characterized after isolation ... | 1985 | 4030530 |

| cloning of enterotoxin gene from aeromonas hydrophila provides conclusive evidence of production of a cytotonic enterotoxin. | culture filtrates of two aeromonas hydrophila strains which were isolated from patients with diarrhea and assumed to be causative agents of the infections were shown to contain enterotoxic, cytotoxic, and hemolytic activities. modest heat treatment of the filtrates inactivated the cytotoxic and cytolytic activities, but not the enterotoxic activity. the construction of cosmid gene banks in escherichia coli of dna from both a. hydrophila strains demonstrated that the determinants of the three act ... | 1984 | 6500697 |
| production of cholera-like enterotoxin by aeromonas hydrophila. | a total of 249 strains of mesophilic aeromonas including 179 a. hydrophila and 70 a. caviae were tested for production of cholera-like enterotoxin by reversed passive latex agglutination (rpla) assay. a cholera-like enterotoxin neutralized with cholera antitoxin was demonstrated in the culture filtrates from eight (4.5%) of the 179 a. hydrophila strains, while none of a. caviae strains revealed the enterotoxin production in the test. production of the cholera-like enterotoxin in the eight strain ... | 1984 | 6503026 |
| isolation of aeromonas spp. from an unchlorinated domestic water supply. | the recovery of aeromonas spp. from the unchlorinated water supply for a western australian city of 21,000 people was monitored at several sampling points during a period of 1 year. membrane filtration techniques were used to count colonies of aeromonas spp., coliforms, and escherichia coli in water sampled before entry to service reservoirs, during storage in service reservoirs, and in distribution systems. aeromonas spp. were identified by subculture on blood agar with ampicillin, oxidase test ... | 1984 | 6486783 |
| the occurrence of aeromonas hydrophila in avian diagnostic submissions. | twenty isolations of aeromonas hydrophila were made from 15 species of free-living, commercial, and companion birds submitted for routine diagnostic postmortem examination. seventy percent of the isolations were made from november through march during the 25-month survey period. | 1984 | 6487200 |
| structure of the lipopolysaccharide core isolated from a human strain of aeromonas hydrophila. | lipopolysaccharide was isolated from the cell-walls of a human strain of aeromonas hydrophila by the aqueous phenol method in 0.58% yield (based on dry weight of bacteria). the lipopolysaccharide consisted of sr-polysaccharide, core-oligosaccharide and lipid a; there was no o-specific polysaccharide. the core had the composition d-galactose, d-glucose, d-glycero-d-manno-heptose, l-glycero-d-manno-heptose and d-glucosamine in a molar ratio of 1:1:2:4:1. glucosamine was linked to an l-glycero-d-ma ... | 1984 | 6489347 |
| action of a microbial glycerophospholipid:cholesterol acyltransferase on plasma from normal and lcat-deficient subjects. | the action of a bacterial acyltransferase similar in overall reaction mechanism to the plasma enzyme lecithin:cholesterol acyltransferase (lcat) has been studied using normal plasma and lipoproteins and plasma from lcat-deficient patients. the microbial enzyme (gcat) catalyzed acyl transfer using phosphatidylcholine and cholesterol in all of the lipoprotein fractions, presumably because it has no apolipoprotein cofactor. in addition, the enzyme was capable of hydrolyzing cholesteryl ester in lip ... | 1984 | 6491538 |
