Abstract:
In this study, the serogroup and susceptibility patterns of Shigella and Salmonella spp. isolated from stool cultures were determined using standard laboratory procedures. Among the 76 Shigella isolates serogroup B (Sh. flexeneri) was the most prevalent species (54.0%) and among the 37 Salmonella strains serogroup B was also the most prevalent (81.1%). Antibiograms of Shigella and Salmonella spp. showed 100% resistance to erythromycin and high resistance rates (> or = 75%) to ampicillin, cephalothin, chloramphenicol and tetracycline. Salmonella spp. also had high resistance to gentamicin, sulphonamide, and trimethoprim-sulfamethoxazole. Shigella were susceptible to gentamicin (100%) and nalidixic acid (97.3%) and Shigella and Salmonella were 100.0% susceptible to norfloxacin.
