Spotted fever group Rickettsia, Anaplasma and Coxiella-like endosymbiont in Haemaphysalis ticks from mammals in Thailand.

ABSTRACT: Ticks are ectoparasites of vertebrates and vectors of various pathogenic microorganisms. In this study, the presence of bacteria and protozoa was evaluated by PCR and DNA sequencing in 233 mammal ticks collected from 8 provinces in Thailand. Sequence and phylogenetic analyses of partial rickettsial ompA, ompB, sca4 and partial Coxiella 16S rRNA, GroEL, rpoB genes clearly revealed, for the first time, a co-infection of SFG Rickettsia belonging to R. massiliae subgroup and Coxiella-like endosymbiont (CLE), Cox-hein, in a male of Haemaphysalis heinrichi tick infesting Burmese ferret-badger in Loei province. Moreover, a male of H. hystricis tick infesting the same host was infected with another CLE, Cox-hys. Based on the 16S rRNA gene sequence, Anaplasma sp., closely related to Anaplasma bovis
