The human body louse is the only known vector of Bartonella quintana. However, the presence of this bacterium has recently been detected in the head lice of homeless individuals and Nepalese slum children. Previous studies have reported the isolation of Acinetobacter baumannii from the body lice of homeless individuals. An epidemiological survey including 74 schools was conducted between 2008 and 2009 in Paris. After a first visual examination, the hair of children with suspected pediculosis was combed with a fine-tooth comb to collect live adult head lice. Molecular studies were performed on randomly selected DNA samples to detect B. quintana and A. baumannii by specific quantitative real-time PCR. Among a collection of 288 DNA samples, B. quintana was not detected, but A. baumannii was detected in 95 DNA samples (33%). Further study is needed to determine the significance of the finding of A. baumannii in head lice.
人体虱是唯一已知的斑疹伤寒立克次体的传播媒介。然而，最近在无家可归者和尼泊尔贫民窟儿童的头虱中检测到了这种细菌。以前的研究报告称，从无家可归者的体虱中分离出了鲍曼不动杆菌。2008 年至 2009 年，在巴黎进行了一项包括 74 所学校的流行病学调查。在第一次目视检查后，用细齿梳子梳理有疑似头虱的儿童头发，以收集活的成年头虱。对随机选择的 DNA 样本进行分子研究，通过特异性实时定量 PCR 检测斑疹伤寒立克次体和鲍曼不动杆菌。在收集的 288 个 DNA 样本中，未检测到斑疹伤寒立克次体，但在 95 个 DNA 样本（33%）中检测到鲍曼不动杆菌。需要进一步研究来确定在头虱中发现鲍曼不动杆菌的意义。
