Abstract

Pathogenesis of Salmonellosis depends upon a large number of factors controlled by an array of genes that synergise into the actual virulence of Salmonella. In the present study, out of 730 samples collected from different poultry farms located in Dakahlia province, Egypt, Salmonella spp were identified in 12%, 8.6% and 3.8% of ducks, chickens and quails respectively. Serological identification showed that the high percentage of isolation was for S. Typhimurium (32.5%) and S. Newport (14%) in chickens, S. Infantis (25%) in ducks and S. Shangani (60%) in quails. Salmonella serovars showed 100% pathogenicity using Embryo lethality assay. The isolated Salmonella serovars were 100% susceptible to only Amikacin and highly resistant to Flumequine, Nalidixic acid, Oxytetracycline, Ampicillin/Sulbctam, Amoxicillin and Trimethoprim–Sulfamethoxazole with the percentages of 90%, 86.7%, 73.3%, 73.3%, 68.3% and 58.3% respectively. The obtained results confirm the need for a country adherence to strict public health and food safety regimes.
