Presence of Aeromonas trota in aquatic environment

Properties of Hemolysin and Protease Produced by Aeromonas trota

We examined the properties of exotoxins produced by Aeromonas trota (A. enteropelogenes), one of the diarrheagenic species of Aeromonadaceae. Nine of 19 A. trota isolates that grew on solid media containing erythrocytes showed hemolytic activity. However, the hemolytic activities of the culture supernatants of these hemolytic strains of A. trota were markedly lower than those of A. sobria when ...

Phenotypic and genotypic identification of Aeromonas species from aquatic environment

A total of 50 strains of Aeromonas spp. were isolated from 50 water and fish samples, and identified biochemically and genetically. Biochemical characterization indicated that 20 out of 50 aeromonads were A. veronii, 19 were A. caviae, 9 were A. hydrophila and 2 were A. trota. Molecular identification of isolated aeromonads revealed restriction profile of four species i.e. A. sobria, A. media, ...

Antimicrobial susceptibility patterns of Aeromonas jandaei, A. schubertii, A. trota, and A. veronii biotype veronii.

Fifty-six isolates of four Aeromonas species, which have been documented as causative agents of human infections or isolated from human clinical specimens, were subjected to antimicrobial susceptibility testing using a MicroScan WalkAway conventional (overnight incubation) gram-negative panel. The four species tested and the number of isolates of each were as follows: Aeromonas jandaei, 17; A. ...

Aeromonas trota sp. nov., an ampicillin-susceptible species isolated from clinical specimens.

Previous DNA hybridization studies established 12 Aeromonas genospecies, from which nine phenotypic species have been proposed: Aeromonas hydrophila, A. sobria, A. caviae, A. media, A. veronii, A. schubertii, A. salmonicida, A. eucrenophila, and A. jandaei. We have delineated a new Aeromonas genospecies, A. trota, on the basis of 13 strains isolated primarily from fecal specimens from southern ...
