AB  - <I>Plesiomonas shigelloides</I> and <I>Aeromonas </I>Species are gram negative organisms which are the members of the expanding group of known water and food borne pathogens and have been increasingly recognized as enteric pathogens. In present study we attempted to map the occurrence and pathogenesis of these bacterias in fish raised pools. We took seventy eight samples from eight fish raised pools and studied their hemolytic, enterotoxin production, motility and antibiotic resistance properties of these bacterias. Frequency of bacterias in these pools were: 5.19% <I>Plesiomonas shigelloides</I>, 51.94%<I> vibrio</I>, 9.09% <I>pseudomonas</I>, 23.07% <I>Aeromonas hydrophila</I>, 15.38% <I>A. Soberia</I>, 38.46% <I>A. kavieh</I>, 23.07% <I>A. trota</I>. In entrotoxin production 50% of <I>P. shigelloides</I> and 62.38% of <I>Aeromonases</I> were positive and in hemolytic activity 50% of <I>P. shigelloides</I> and 19.23% of <I>Aeromonases</I> were positive. Most strains were resistant to penicilline; ampiciline and carbenicillinand were sensitive to tetracycline, Toberamycine and cotrimoxasol. In conclusion, our results indicate that <I>P. shigelloides</I> and <I>Aeromonases</I> are able to product a variety of potential virulence markers which may be involved in the pathogenesis of their associated infections and should be given due attention as they might play an important role in the etiology of human gastroenteriticity.
