aeromonas species in clinical microbiology: significance, epidemiology, and speciation.over a one-year period, 32 strains (31 clinical, 1 environmental) of aeromonas sp. were recovered. chief sources of isolation were the gastrointestinal tract (48%), wounds (19%), and blood (13%). gastrointestinal isolates were most often recovered from young (less than 5 yrs) children with diarrhea; wound or blood isolates were recovered more often from an older (avg. 56 yrs) population with one of several underlying disorders. regardless of body site of isolation, most strains of aeromonas appe ...19836673896
regrowth of potential opportunistic pathogens and algae in reclaimed-water distribution systems.a study of the quality of reclaimed water in treated effluent, after storage, and at three points in the distribution system of four plants in california, florida, massachusetts, and new york was conducted for 1 year. the plants had different treatment processes (conventional versus membrane bioreactor), production capacities, and methods for storage of the water, and the intended end uses of the water were different. the analysis focused on the occurrence of indicator bacteria (heterotrophic ba ...201020453149
population dynamics of aeromonas spp. in an urban river watershed.density of aeromonas spp. at one site in the buffalo river and at four sites on its upstream tributaries was followed from june 1992-june 1993. membrane filtration counts of aeromonas during the summer ranged between 18 and 4000 ml-1, which were one to two logs higher than faecal coliform and faecal streptococci densities. aeromonas spp. in the buffalo river, and faecal coliforms, faecal streptococci, and the heterotrophic plate count throughout the watershed, increased by approximately one log ...19989812384
cloning and biochemical characterization of fox-5, an ampc-type plasmid-encoded beta-lactamase from a new york city klebsiella pneumoniae clinical isolate.klebsiella pneumoniae 5064, isolated in new york, carried plasmid-mediated resistance to multiple beta-lactams and was unresponsive to clavulanic acid. the beta-lactamase gene responsible for cephalosporin resistance encoded fox-5, with 96 to 97% amino acid identities to other members of the fox family of beta-lactamases. the bla(fox-5) coding region was located next to a transposase gene from the aeromonas salmonicida insertion element isas2.200111600376
the role of seafood in foodborne diseases in the united states of america.in the united states of america, seafood ranked third on the list of products which caused foodborne disease between 1983 and 1992. outbreaks connected with fish vectors were caused by scombroid, ciguatoxin, bacteria and unknown agents; in shellfish, unknown agents, paralytic shellfish poisoning, vibrio spp. and other bacteria, followed by hepatitis a virus, were responsible for the outbreaks. at least ten genera of bacterial pathogens have been implicated in seafood-borne diseases. over the pas ...19979501377
hemagglutination patterns of aeromonas spp. in relation to biotype and source.aeromonas spp. show patterns of hemagglutination with human group o cells in the presence of fucose, galactose, and mannose. these patterns are related to biotype as well as to the source of isolates. there was good correlation between hemagglutination pattern and the presence of diarrhea among strains isolated in western australia, which was the only source with adequate data for classification of children with an without diarrhea. most of the environmental and other nonfecal isolates produced ...19846690466
comparison of antibodies in marine fish from clean and polluted waters of the new york bight: relative levels against 36 bacteria.fish from polluted waters are subject to increased prevalence of disease. because they respond to bacterial pathogens by producing serum antibodies, it was possible to construct a seasonal serological record in three fish species from clean and polluted waters of the new york bight. antibody levels were determined by testing sera for agglutinating activity against 36 strains of bacteria. evaluation of 5,100 antibody titrations showed the following. during warm months, summer flounder (paralichth ...1979518084
biochemical characteristics and virulence of environmental group f bacteria isolated in the united states.bacteria phenotypically resembling aeromonas hydrophila, but requiring nacl for growth, have been isolated form the new york bight. the bacteria proved to be identical to group f organisms isolated from cases of human diarrhea in indonesia and bangladesh. anaerogenic strains initiated responses in y-1 tissue culture and rabbit ileal loop, consistent with those associated with cytotoxin- and enterotoxin-producing aeromonas spp. strains. separation on the basis of production of gas from glucose by ...19807425623
quantitative and qualitative studies of gut flora in striped bass from estuarine and coastal marine environments.examination of the intestinal contents of 130 striped bass (morone saxatilis) collected from the hudson river and long island sound during may to october 1981 showed that opportunistic fish pathogens--especially aeromonas hydrophila--predominated in samples from both locations. other isolates from both groups of striped bass included vibrio, pseudomonads, flavo-bacteria, alcaligenes, and enterics. small numbers of micrococcus, bacillus, corynebacterium, and acinetobacter were also isolated. tota ...19863735580
aeromonas hydrophila diarrhea in a long-term care setting.infectious diarrheal diseases can be a serious problem in long-term care institutions. aeromonas hydrophila, a facultative, anaerobic gram-negative rod, has not been implicated previously in an acute diarrheal outbreak in this setting. we report 17 patients with this disorder all characterized by the acute onset of painless, nonbloody diarrhea. thirteen of 17 (76%) patients had two to four loose bowel movements and a duration of illness of less than 48 hours. eleven of 17 (65%) patients were afe ...19902370399
