Abstract:Anaplasma phagocytophilum and Borrelia burgdorferi sensu lato are the causative agents of human granulocytic anaplasmosis (HGA) and Lyme disease (LD), respectively. Transmissions of HGA and LD are mainly related to tick bite. Little information is available concerning the prevalence and coinfection of A. phagocytophilum and B. burgdorferi s.l. in tick in China. In this study, prevalence of A. phagocytophilum and B. burgdorferi s.l. was assessed by investigating 543 samples of three tick species collected in Gansu, Hunan and Guangdong provinces in China. The prevalence of infection varied from 3.2% to 20.0% for A. phagocytophilum and from 2.3% to 19.3% for B. burgdorferi s.l. in different collection sites. Coinfection with A. phagocytophilum and B. burgdorferi s.l. was found in 7 (1.3%) ticks. In this study, we also found that H. qinghaiensis, R. sanguineus and B. microplus were infected with these pathogens, which indicated that the investigated tick species may be involved in the maintenance of A. phagocytophilum and B. burgdorferi s.l.. Our results add new information on the epidemiology and may contribute to the improvement of control strategies in the study sites.
