Abstract：Objective To investigate the leptospirosis and bartonella infection among patients with fever of unknown origin (FUO) in Yunnan Province. Methods For the patients with FUO, serum leptospirosis antibody was tested by microscope agglutination test (MAT), and serum Bartonella henselae(B. henselae) and Bartonella Quintana (B. quintana) IgG antibodies were tested by indirect immunofluorescence assay (IFA). Results Totally, sera from 232 patients with FUO were tested. The infection rate of B. henselae (30.17%) was higher than those of B. quintana (18.10%) and leptospirosis (4.74%). The mixed infection rate of B. henselae and B. quintana (14.22%) was higher than that of leptospirosis and B. henselae (2.16%), as well as that of leptospirosis and B. quintana (0.86%). One case had antibodies for leptospirosis, B. henselae and B. quintana. Conclusions Some patients with FUO are actually infected with leptospirosis, and/or Bartonella henselae and/or Bartonella quintana. The infection rates are different, and mixed infection is common. It is necessary to carry out leptospirosis and bartonella screening to diagnose fever of unknown origin.
