Abstract

In the present study a total of 240 samples were collected from clinically diseased chicks and examined for the presence of Salmonella. Fifty bacterial isolates were recovered and proved to be belonged to Salmonella serovars with an incidence of 20.8%. Salmonella isolates were serologically typed as S.Kentukey 20%(10\50), S. Infantis 24%(12\50), S. Hiedelberg (10% (S\S0), S. Labadi 6%(3\50), S. Enteritidis 14%(7\50), S.Typhi 4%(2\50), S. Agona 4%(2\50), S.Pullorum 2% (1\50), and S. Newport 6% (3\50).A large percentage of isolates were resistant to Ampicillin (90%), Nalidexic acid (88%),Sulphamethoxasole + Trimethoprim (82%) and Tetracyclines (82%). Approximately 86% of the isolates demonstrated multiple-resistance (i.e. resistance to 3 groups antimicrobial types). Phenotypic detection of ESβLS by using screening test (Cefinase®) revealed that 32% of isolates were positive for extended spectrum beta lactimase (ESβLS).
