Survival of antibiotic resistant Aeromonas strains in different water conditions

Studies were conducted to find out the survival of three antibiotic resistant Aeromonas strains in different types of water. The selected Aeromonas strains were A. hydrophila (local), A. sobria (local) and A. hydrophila (Thai), which were only recovered from farmed fishes. Seven types of water were used. Among these experimental water, lake water, distilled water and fish farm pond water had supported the long time survival of A. hydrophila. In contrast, private fish farm pond water was the most favorable for A. sobria. Deionized water was found not to support the survival of any species but Masjid pond water and FRI pond water were found to be moderately suitable for all the species. However, the survival pattern of Thai strain of A. hydrophila was found to have similarity with the survival of the local strain of A. hydrophila.
