Abstract :
Aeromonas hydrophila is one of the most frequent pathogens of acute bacterial gastroenteritis particularly in young children and elderly which is transmitted mostly via water and food originating from animals. study was conducted to determine the prevalence rate of A. hydrophila in fish, shrimp and lobster caught off the south coast of Iran. A total of 180 samples including, 110 fish, 40 freshly caught shrimp, and 30 freshly caught lobsters (Panulirus homarus) were collected in 3 provinces along Persian Gulf in the south coast of Iran. A biochemical protocol was applied for identification of the isolates. Samples were collected at the end of each month from summer 2010 to spring 2011. In this study, 18 of 180 samples (10.0%) including 13 of 110 fish samples (11.8%), and 4 of 40 shrimp samples (10%) were contaminated with A. hydrophila. The highest prevalence of A. hydrophila occurred in summer (17.5%) followed by fall (10.1%), and winter (4.9%). To our knowledge, the present study is the first report of the isolation of A. hydrophila from fish, shrimp and lobster in Iran.
