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.
在本研究中，采用标准实验室程序确定从粪便培养物中分离出的志贺氏菌属和沙门氏菌属的血清群及药敏模式。在76株志贺氏菌分离株中，B群（福氏志贺氏菌）是最常见的菌种（54.0%），在37株沙门氏菌菌株中，B群也是最常见的（81.1%）。志贺氏菌属和沙门氏菌属的抗菌谱显示对红霉素100%耐药，对氨苄青霉素、头孢噻吩、氯霉素和四环素耐药率高（≥75%）。沙门氏菌属对庆大霉素、磺胺类药物及甲氧苄啶-磺胺甲恶唑也有较高耐药性。志贺氏菌对庆大霉素（100%）和萘啶酸（97.3%）敏感，志贺氏菌属和沙门氏菌属对诺氟沙星的敏感性均为100.0%。
