ABSTRACT

Salmonellosis is one of the most common and widely distributed disease affecting both man and animals. Presence of drug resistant Salmonella in poultry and poultry products further pose a risk to public health. This study was undertaken to determine the prevalence of Salmonella in poultry. Of 350poultry faecal as well as cloacal swab samples analyzed, 6 (1.7%) yielded Salmonella which comprised of Salmonella Paratyphi B (3), Salmonella Typhimurium (2) and Salmonella Stanley (1). The culture protocol used included pre-enrichment in buffered peptone water, enrichment in Rappaport-Vassiliadis broth and selective plating on brilliant green agar. In order to study the antibiogram pattern of isolated Salmonella organisms, seven antimicrobial drugs comprising chloramphenicol, ciprofloxacin, oxytetracycline, nalidixic acid, gentamicin, erythromycin and cotrimoxazole were subjected to drug sensitivity test. Interestingly, all the isolates were found sensitive to chloramphenicol, ciprofloxacin, cotrimoxazole, oxytetracycline and gentamicin while 83.3% of the isolated Salmonella serovars were resistant to nalidixicacid and erythromycin.
