Abstract

Intoduction: Patient-care equipment and inanimate objects contaminated with bacteria are a persistent problem in countries like Ethiopia, and remain overlooked. This study aimed to elucidate the magnitude of contaminations, diversity, and antimicrobial-susceptibility patterns of bacterial isolates from selected wards of Arba Minch General Hospital, Ethiopia.

Methods: Samples were inoculated into bacteriological media and identified by biochemical characterization, followed by antimicrobial-susceptibility tests.

Results: Of the 99 inanimate objects and items of patient-care equipment examined, 71 (71.7%) showed contamination: 26 (76.4%) from the surgical ward and 22 (66.6%) and 23 (71.8%), respectively, from the pediatric ward and neonatal intensive care unit. In the case of Gram-positive bacteria, coagulase-negative staphylococci (CoNS; 52.2%) were predominant, followed by Staphylococcus aureus (47.7%), whereas common Gram-negative counterparts were Acinetobacter spp. (28.5%) and Klebsiella spp. (23.8%). Antibiograms of S. aureus and CoNS showed 100% and 78% resistance, respectively, against penicillin. Isolates of Acinetobacter spp. showed 100% resistance to ceftriaxone and ampicillin, whereas those of Klebsiella spp. displayed complete resistance against ampicillin and trimethoprim-sulfamethoxazole. All isolates of Citrobacter spp., Enterobacter spp., Salmonella spp., Escherichia coli, and Serratia spp. exhibited 100% resistance to amoxicillin, ampicillin, and trimethoprim-sulfamethoxazole. Overall prevalence of multidrug-resistant bacteria was 57.7%.

Conclusion: A stringent infection-vigilance program comprising routine sampling from equipment and inanimate objects combined with antimicrobial-resistance surveillance and decontamination efforts must be instituted promptly.

埃塞俄比亚南部Arba Minch综合医院选定病房中从病人护理设备和无生命物体中分离的细菌的数量、多样性和抗生素谱
导言:在埃塞俄比亚等国家,被细菌污染的病人护理设备和无生命物体是一个长期存在的问题,而且仍然被忽视。本研究旨在阐明从埃塞俄比亚Arba Minch总医院选定病房分离的细菌的污染程度、多样性和抗菌素敏感性模式。方法:将样品接种于细菌学培养基中,进行生化鉴定,并进行药敏试验。结果:在检查的99个无生命物体和患者护理设备中,有71个(71.7%)存在污染,其中外科病房有26个(76.4%),儿科病房和新生儿重症监护病房分别有22个(66.6%)和23个(71.8%)。革兰氏阳性菌中凝固酶阴性葡萄球菌(con;其次是金黄色葡萄球菌(47.7%),常见的革兰氏阴性为不动杆菌(28.5%)和克雷伯氏菌(23.8%)。金黄色葡萄球菌和金黄色葡萄球菌对青霉素的耐药率分别为100%和78%。不动杆菌对头孢曲松和氨苄西林100%耐药,而克雷伯菌对氨苄西林和甲氧苄啶-磺胺甲恶唑完全耐药。所有分离的柠檬酸杆菌、肠杆菌、沙门氏菌、大肠杆菌和沙雷氏菌对阿莫西林、氨苄西林和甲氧苄啶磺胺甲恶唑均表现出100%的耐药性。耐多药菌总体患病率为57.7%。结论:必须立即制定严格的感染警戒计划,包括从设备和无生命物体中进行常规采样,并结合抗菌素耐药性监测和去污工作。
