Head and clothing lice from Jimma, Ethiopia were investigated for pathogenic bacteria. Genomic DNA from pools of lice was subjected to PCR analysis for Bartonella spp., Borrelia spp. Coxiella burnetii, Rickettsia spp. and Yersinia pestis. All 102 lice pools were negative for the afore mentioned pathogens, with the exception of Bartonella species found among 6 of 65 (9.2%) head lice pools and1 of 33 clothing lice pools. Identification was achieved by sequencing the ribosomal intragenic transcribed spacer region (ITS), revealing all to be Bartonella quintana. Although established as a clothing louse-borne infection, typically causing chronic bacteraemia, trench fever, bacillary angiomatosis and endocarditis, this has only been rarely reported among head lice. The higher numbers of infected head lice pools compared with clothing lice suggests their competence for maintaining this infection within Ethiopia.
对来自埃塞俄比亚吉马的头虱和体虱进行了致病性细菌调查。将虱子的基因组 DNA 进行 PCR 分析，用于检测巴尔通体属、螺旋体属、柯克斯体、立克次体属和鼠疫耶尔森菌。除了在 65 个头虱池中的 6 个（9.2%）和 33 个体虱池中的 1 个中发现的巴尔通体属外，所有 102 个虱子池均未检测到上述病原体。通过对核糖体基因内转录间隔区（ITS）进行测序来鉴定，结果均为贝氏柯克斯体。尽管它被认为是一种体虱传播的感染，通常会导致慢性菌血症、战壕热、杆菌性血管瘤和心内膜炎，但在头虱中很少有报道。与体虱相比，感染头虱的池数量更多，这表明它们在埃塞俄比亚有能力维持这种感染。
