RESUMO
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 [>/= 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
