Several outbreaks of trench fever caused by Bartonella quintana occurred in soldiers during World Wars I and II. Although trench fever cases have been decreasing worldwide, the disease was reported among the homeless population in developing and developed countries. The current prevalence of B. quintana infection in Japan is unclear. Blood and body louse (Pediculus humanus humanus) samples were obtained from homeless inpatients with body lice during emergency hospitalization in Tokyo from January 2013 to March 2015. Patients were tested for B. quintana infections using the culture method, polymerase chain reaction, and indirect immunofluorescence assay (IFA). Among the 29 patients tested, the presence of Bartonella spp. was confirmed by genomic sequencing of DNA extracted from two samples from blood culture performed for 15 out of 29 patients and from body louse samples of 20 patients (69\%). Immunoglobulin G against B. quintana was detected in 10 patients (34.5\%) at a cut-off titer of 1:256 in IFA. B. quintana infection was detected in samples obtained between 2013 and 2015 in Tokyo and needs to be on the list of differential diagnoses performed for febrile homeless individuals.

Trench fever is a body louse-borne disease caused by Bartonella quintana Brenner. The recent status of louse infestation in Nepalese children is not well known. We collected head and body lice, Pediculus humanus capitis De Geer and Pediculus humanus humanus L., respectively, from 30 children, including 11 cases of double infestation with both head and body lice. Detection of B. quintana in both louse species identified was carried out by polymerase chain reaction (PCR). PCR products with B. quintana DNA sequences were detected in both head and body lice from two children as well as in body lice derived from two other children. These results demonstrate that head lice may also play a role in the transmission of trench fever.
