Abstract


We detected Bartonella quintana in 48.6% of captive rhesus macaques from an animal facility in Beijing, China. Prevalence of infection increased over the period of observation. Our findings suggest that macaques may serve as reservoir hosts for B. quintana and that Pedicinus obtusus lice might act as efficient vectors.



Bartonella quintana is a vector-transmitted, hemotropic, and extremely fastidious gram-negative bacterium. Infection with B. quintana has been recognized to cause a broad spectrum of disease, including trench fever, chronic bacteremia, endocarditis, and bacillary angiomatosis (1�?"4). Humans are the primary reservoir host for B. quintana, which, unlike most other Bartonella species, lacks an identified animal reservoir, although some recent reports have found B. quintana in dogs and in cynomolgus and rhesus macaques (5�?"7). Almost 60 years ago, rhesus macaques were able to be experimentally infected with B. quintana (8). However, nonhuman primates have not been shown to support long-term maintenance, multiplication, and transmission of this pathogen, all of which would be expected if these animals were to act as reservoir species. Observations of monkey ectoparasites transmitting B. quintana between nonhuman primates or infecting humans have also not been reported.
