  Pseudomonas aeruginosa a potential risk factor for food poisoning especially in aquatic foods like shrimp. In order to determine and compare the rate of infection in different species of shrimp in two seasons of summer and autumn in Isfahan and Chabahar cities, the abdominal muscle of 35 shrimps in each season of each city were sampled. Samples were homogenized in peptone water medium, then incubated and cultured in PCA medium. Suspected colonies were isolated and then confirmatory tests of Pseudomonas aeruginosa and confirmation of the presence of nanI, the specific gene of Pseudomonas aeruginosa by PCR.In summer, in Isfahan and Chabahar, 48.5% and 25.7% were infected respectively. In autumn, the prevalence was 22.9% for Isfahan and 20% for Chabahar, respectively. In Isfahan, the highest rate of infection was related to Metapenaueus affinis and the lowest to Penaeus semisulcatus in summer. In autumn, the highest number of infected samples was related to Penaeus merguiensis and the lowest to Penaeus semisulcatus. In Chabahar city, in both seasons, the most infected samples were related to Metapenaeus affinis, and the lowest to Panaeus semisulcatus and in autumn was related to both Penaeus semisulcatus and Litopenaeus vannamei.There was a high prevalence of this bacterium in samples of different shrimp species in both seasons and both cities, which indicates a high risk of food poisoning of Pseudomonas aeruginosa due to improper consumption of shrimp. Cold chain observance during storage, transportation and sell of shrimp will be very effective in controlling this problem. Manuscript profile
