Abstract
Salmonella is regarded as the main pathogenic bacteria among other foodborne diseases worldwide and the increase in salmonella injury is linked with the spread of antimicrobial-resistant strains. Meat products are important vehicles for the transmission of salmonella. Salmonella isolates were then serotyped in the Serology Unit Animal Health Research Institute, Doki, Giza Egypt using commercial antisera (Difco, Detroit, MIUSA) according to the manufacturer’s instructions. In this study, a total of 50 meat products were purchased from different supermarkets in Sharkia Providence, Egypt, and underwent bacteriological examination to survey the incidence of salmonellosis infection. The prevalence rate was 26% with predominance for the S. Typhimurium serotype followed by S. Enteritidis, and S. Virchow. All Salmonella species were sensitive to ceftriaxone (100%) and 61.5% of isolates were multidrug-resistant (MDR). Strong resistance was exhibited towards ceftazidime and ampicillin-sulbactam. In conclusion, the study gave a sufficient picture of the incidence, drug resistance, and phenotypic characterization of different salmonella serovars from food products.
