A survey was conducted to ascertain the distribution and virulence of Aeromonas spp. (species) in carabeef and mutton samples in Greater Hyderabad Municipal Corporation, India. Conventional method using Aeromonas isolation medium and Ampicillin Dextrin agar, PCR targeting 16S rRNA were used to identify Aeromonas spp. in meat samples. Conventional cultural method revealed 28% and 40% positives i...

We have investigated the existence and genetic organization of a functional type III secretion system (TTSS) in a mesophilic Aeromonas strain by initially using the Aeromonas hydrophila strain AH-3. We report for the first time the complete TTSS DNA sequence of an Aeromonas strain that comprises 35 genes organized in a similar disposition as that in Pseudomonas aeruginosa. Using several gene pr...

One thousand and three diarrhoeal stool samples were processed in our laboratory during the period 1996/1997 for the presence of enteric pathogens especially Aeromonas spp., which has emerged as a new agent causing diarrhoea. Ampicillin sheep blood agar was found to be the best medium for the isolation of Aeromonas spp. from stool specimens. Enteric pathogens were found in 200 (20%) stools, of ...

Although there is substantial evidence that type IV pili purified from diarrhea-associated Aeromonas species (designated Bfp for bundle-forming pilus) are intestinal colonization factors (S. M. Kirov, L. A. O'Donovan, and K. Sanderson, Infect. Immun. 67:5447-5454, 1999), nothing is known regarding the function of a second family of Aeromonas type IV pili (designated Tap for type IV Aeromonas pi...

Background: The genus Aeromonas include gram-negative, motile, facultative anaerobic, rod shaped and oxidase positive bacteria comprising several species, associated with the aquatic environment. Aeromonas species have been implicated in human pathogenesis and are linked with gastroenteritis, muscle infections, septicemia, and skin diseases. In fish they are renowned as enteric pathogens causin...

The present study deals with the isolation and characterization of protease producing Aeromonas hydrophila from diseased catfish. To isolate Aeromonas hydrophila from diseased catfish, Confirmation using biochemical tests. The effect of pH, temperature on the growth of Aeromonas hydrophila was conducted and checked the cytotoxicity of the enzyme protease responsible for pathogenicity in fishes....

Aeromonas hydrophila, an anaerobic gram-negative bacillus, can cause severe infections in immune-compromised patients. We present a 45-year-old cirrhotic man who suffered from hematemesis and received emergency endoscopic injection sclerotherapy (EIS) for gastric variceal bleeding. Twenty-one hours after EIS, painful swelling of the bilateral lower extremities and fever occurred. Severe soft-ti...

Type III secretion genes in Aeromonas salmonicida subsp. salmonicida are located on a large plasmid of approximately 140 kb. Cultivation of this organism at elevated temperatures such as 25 degrees C can, however, result in loss of this plasmid. This is accompanied by a loss of virulence for cultured fish cells.
