Abstract:

All serotypes of non-typhoid Salmonella are considered as a potential hazard to human health and measures to prevent food-borne salmonellosis should therefore be directed there wise. Here we sought to report the identification and incidence of S. enteritidis and S. typhimurium yafD and xthA gene families that are responsible for their persistence in egg albumen and their survival in egg are important for their transmission to the human population. The total incidence of Salmonella in the albumen samples was detected as 10.1% of the samples [Salmonella enteritidis (7.1%) and S. typhimurium (3.1%)]. As carrier for the yafD (86.7%) and xthA (13.3%) genes, S. enteritidis accounted for 85.0% of the Salmonella serotype isolates. On the other hand, S. typhimurium carrying the xthA gene, accounted for 100% of the total egg albumen Salmonella serotypes with the absence of the yafD gene from all of the S. typhimurium isolates.
