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 was also detected in a male of H. heinrichi infesting the same Burmese ferret-badger. In addition, the third CLE, Cox-asia, found in H. asiatica collected from Asian palm civet in Chiang Rai province, was different from both Cox-hein and Cox-hys. This study provided important data and broadened our knowledge on tick-borne pathogens and endosymbionts in Thailand and Southeast Asia.
