Abstract:The aim of this study is to understand the present situation of Anaplasma phogocytophila infection and the co-infection with Borrelia burgdorferi and Orientia tsutsugamushi in populations of the Wuyishan forest area of Fujian province,so as to provide scientific basis for the strategy of treatment and prevention..Indirect fluorescence assay(IFA) was used to detect the presence of IgG antibodies against A.phagocytophila,B.burgdorferi and O.tsutsugamushi in sera of workers,peasants and cadres at the basis in the forest area.All together,a total of 269 samples of serum were collected and tested.The establishment of database and statistical analysis were performed by SPSS 14.0 with a significance level of χ2test at α=0.05.It was found that among these 269 serum samples taken,46 serum samples appeared to be positive for IgG antibody against A.phagocytophila,with a positive rate of 17.10% and in these 46 positive samples for A.phagocytophila,one sample and 9 samples were positive for antibodies against B.burgdorferi and O.tsutsugamushi respectively.In the positive serum samples,no satistic difference existed in area,gender and occupation except age.It is concluded that endemic A.phagocytophila infection exists in the north forest area of Fujian province and co-infected with B.burgdorferi and O.tsutsugamushi.So the works of prevention and treatment of anaplasmosis,Lyme's disease and scrub typhus should be undertaken simultaneously.
