BACKGROUND
Cockroaches have been described as potential vectors for various pathogens for decades; although studies from neonatal intensive care units are scarce. This study assessed the vector potential of cockroaches (identified as Blatella germanica) in a neonatal intensive care unit setup in Tikur Anbessa Hospital, Addis Ababa, Ethiopia.
METHODS
A total of 400 Blatella germanica roaches were aseptically collected for five consecutive months. Standard laboratory procedures were used to process the samples.
RESULTS
From the external and gut homogenates, Klebsiella oxytoca, Klebsiella pneumoniae, Citrobacter spp. Enterobacter cloacae, Citrobacter diversus, Pseudomonas aeruginosa, Providencia rettgeri, Klebsiella ozaenae, Enterobacter aeruginosa, Salmonella C1, Non Group A streptococcus, Staphylococcus aureus, Escherichia coli, Acinetobacter spp. and Shigella flexneri were isolated. Multi-drug resistance was seen in all organisms. Resistance to up to all the 12 antimicrobials tested was observed in different pathogens.
CONCLUSION
Cockroaches could play a vector role for nosocomial infections in a neonatal intensive care unit and environmental control measures of these vectors is required to reduce the risk of infection. A high level of drug resistance pattern of the isolated pathogens was demonstrated.
背景
几十年来，蟑螂一直被描述为各种病原体的潜在载体；尽管新生儿重症监护病房的研究很少。本研究评估了埃塞俄比亚亚的斯亚贝巴提克里安巴萨医院新生儿重症监护病房环境中德国蟑螂（被鉴定为德国小蠊）的媒介潜力。
方法
在连续五个月的时间里，无菌收集了总共 400 只德国小蠊。采用标准实验室程序处理样本。
结果
从外部和肠道匀浆中分离出了产酸克雷伯菌、肺炎克雷伯菌、柠檬酸杆菌、阴沟肠杆菌、差异柠檬酸杆菌、铜绿假单胞菌、雷特氏普罗威登斯菌、臭鼻克雷伯菌、铜绿假单胞菌、沙门氏菌 C1、非 A 组链球菌、金黄色葡萄球菌、大肠杆菌、不动杆菌和福氏志贺菌。所有的生物体都表现出了多药耐药性。不同的病原体对多达 12 种测试的抗生素都有耐药性。
结论
蟑螂可能在新生儿重症监护病房中扮演医院感染的媒介角色，需要采取环境控制措施来降低感染风险。所分离的病原体表现出高水平的耐药模式。
