Bacteriocin-like Substance of Aeromonas hydrophila

Bacteriocin-like substance of Aeromonas hydrophila.

The genus Aeromonas comprises Gram negative rods found mainly in aquatical environments that may infect humans and animals (JM Janda 1991 Clin Microbiol Rev 4: 397-410). In humans, some Aeromonas species have been associated with intestinal and extraintestinal infections and enterotoxins, cytotoxins as well as invasive mechanisms have been incriminated in the development of illness in the host ...

Aeromonas hydrophila

Department of Biology, University of Alabama a t Birmingham, Birmingham, AL 35294-1 170, USA Aeromonas hydrophila, a gastrointestinal pathogen of humans, was shown to exhibit a significant adaptive acid tolerance response (ATR) capable of protecting cells from severe acid at a pH of 3.5. The ATR was induced by exposure to a relatively mild pH level of 5-0 for 20 min. Adaptation required protein...

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...

Antimicrobial susceptibility of Aeromonas hydrophila.

Minimal inhibitory concentration determinations and disk diffusion and Autobac 1 susceptibility tests were performed on 22 strains of Aeromonas hydrophila. Eleven of the strains had discrepancies between Autobac and disk diffusion or minimal inhibitory concentration results. These discrepancies occurred with the beta-lactam antibiotics, primarily carbenicillin and cephalothin. It is recommended...
