aeromonas hydrophila secretes several extracellular proteins including enterotoxin, hemolysin and aerolysin that are associated with the bacterial virulence. previous studies have shown that two hemolytic toxins, hemolysin a and aerolysin a contribute to the virulence of aeromonas hydrophila. in the current study, a total of 50 strains of aeromonas hydrophila, including 28 (56%) strains isolate...

Ten strains of Aeromonas hydrophila isolated from water samples were characterized by various methods including biochemical and physiological tests, as well as PCR-RFLP analysis with Universal 16s rRNA primers. Biochemical characterization and PCR-RFLP analysis proved to be useful, rapid and reliable method for identifying widely distributed Aeromonas spp. from environmental samples. The signif...

Aeromonas spp., opportunistic pathogens of humans and fish, are ubiquitous in the aquatic environment. Aeromonas hydrophila and Aeromonas caviae have increasingly been isolated from patients with gastroenteritis and superficial wound infections and the former also has been associated with hemorrhagic septicemia in fish. This is the first study to report Aeromonas occurrence and frequency of vir...

The genus Aeromonas is ubiquitous in aquatic environments encompassing a broad range of fish and human pathogens. Aeromonas strains are known for their enhanced capacity to acquire and exchange antibiotic resistance genes and therefore, are frequently targeted as indicator bacteria for monitoring antimicrobial resistance in aquatic environments. This study evaluated temporal trends in Aeromonas...

Aeromonas is ubiquitous in aquatic environments and has been associated with a number of extra-gastrointestinal and gastrointestinal illnesses. This warrants monitoring of raw and processed water sources for pathogenic and toxigenic species of this human pathogen. In this study, a total of 17 different water samples [9 raw and 8 treated samples including 4 basin water (partial sand filtration) ...

Transposon and marker exchange mutagenesis were used to evaluate the role of Aeromonas cytotoxic enterotoxin (Act) in the pathogenesis of diarrheal diseases and deep wound infections. The transposon mutants were generated by random insertion of Tn5-751 in the chromosomal DNA of a diarrheal isolate SSU of Aeromonas hydrophila. Some of the transposon mutants had dramatically reduced hemolytic and...

BACKGROUND Aeromonas species are common inhabitants of aquatic environments giving rise to infections in both fish and humans. Identification of aeromonads to the species level is problematic and complex due to their phenotypic and genotypic heterogeneity. METHODOLOGY/PRINCIPAL FINDINGS Aeromonas hydrophila or Aeromonas sp were genetically re-identified using a combination of previously publi...

Aeromonas is recognized to cause a variety of diseases in man. In humans, they are associated with intestinal and extra-intestinal infections. With the growing importance of Aeromonas as an emerging pathogen, it is important to combat this organism. It is indisputable that Aeromonas strains may produce many different putative virulence factors such as enterotoxins, hemolysins or cytotoxins, and...

Aeromonas hydrophila inhabits freshwater and soil and is mainly pathogenic to cold-blooded animals. It is known to cause red leg disease in frogs, septicemia and stomatitis in snakes and infections in freshwater fish. 1 Human infections due to members of the genus Aeromonas are considered rare and mainly occur in immune compromised individuals or patients who are suffering from chronic disease....

Aeromonas hydrophila is an opportunistic pathogen residing in freshwater environments that causes infection in fish and mammals. Here, we report the draft genome sequence of A. hydrophila strain TN97-08 isolated from a diseased bluegill (Lepomis macrochirus) in 1997.
