High prevalence of clonally related multiple resistant Salmonella Infantis carrying class 1 integrons in broiler farms.

The poultry industry in Iran is the main supplier of protein in the food chain. In the present study, we showed the importance of the possible dissemination of clonally related multiple drug resistant (MDR) Salmonella Infantis in broiler farms in Iran. In total, 156 fecal samples belonging to 23 poultry farms in Razavi Khorasan province, northeast of Iran, were examined for the presence of Salmonella serovars.
