Aeromonads have been isolated from patients with diarrhea. In spite of a number of virulence factors produced by Aeromonas species, their association with diarrheal diseases has not been clearly linked. In current study, 1546 fecal samples of a randomly selected population were screened for presence of A. hydrophila. Out of the total number of cases, 20 were suffering from diarrhoea and the rest were asymptomatic healthy individuals. The result showed that 3.4% of the samples were positive for Aeromonas spp. A. hydrophila was isolated as the sole enteropathogen from 80% diarrheal and 20% asymptomatic cases. A significant association was found between the A. hydrophila and diarrhoeal diseases in rural and urban areas (P https://ijph.tums.ac.ir/index.php/ijph/article/view/1906 https://ijph.tums.ac.ir/index.php/ijph/article/download/1906/1887
