Aeromonas proteolytica--a halophilic aeromonad?

Abstract

Aeromonas proteolytica, a halophilic bacterium originally isolated from the intestine of a marine isopod, was compared with 93 strains of Aeromonas hydrophila and representative strains of five similar genera in a computer and serological analysis. Aeromonas proteolytica was peritrichate and non-reactive with six A. hydrohila antisera, and possessed a percentage guanine + cytosine ratio (49.5) outside the range for other aeromonads (55-62%). Moreover, in the computer analysis it shared a lower level of similarity with other aeromonads than with both strains of Vibrio anguillarum tested.
