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.

Aeromonas spp. are Gram-negative rods ubiquitous in aquatic environments; however, some species are able to cause a variety of infections in humans. Here, we report the draft genome sequence of Aeromonas caviae 8LM isolated from stool culture from a child with diarrhea in southern Brazil.

Here the data on evolutionary relationships of persistent bacteria from water tanks and their close relatives are shown. Curated sequences of the hypervariable region of ribosomal ribonucleic acid (rRNA) obtained from a strain of Aeromonas hydrophila and two strains of Serratia proteamaculans after searches in the GenBank® database were analyzed. The analysis which included 104 other bacteria s...

Aeromonas hydrophila AL09-71 was isolated from diseased channel catfish in west Alabama during a 2009 disease outbreak. The full genome of A. hydrophila AL09-71 is 5,023,861 bp. The availability of this genome will allow comparative genomics to identify genes involved in pathogenesis or immunogens for the purpose of vaccine development.
