| Abstract |
enetic diversity, genetic structure and demographic history of the ticks infesting beef cattle in Thailand were
examined based on mitochondrial cytochrome c oxidase I (cox1) sequences. Tick samples were collected in 12
provinces in upper-northeastern Thailand. Three species were found; Rhipicephalus microplus, R. sanguineus, and
Haemaphysalis bispinosa. Of these, R. microplus was by far the most abundant species in beef cattle and was widely
distributed throughout the area. No cox1 sequence variation was found in the R. sanguineus or H. bispinosa
specimens collected. Low nucleotide diversity but high haplotype diversity was observed in R. microplus. All
collected R. microplus specimens belonged to lineage A. Mismatch-distribution analysis, as well as Tajima’s D and
Fu’s Fs tests, provided evidence of recent demographic expansion. A subsample of tick specimens was investi-
gated for presence of Anaplasma and Ehrlichia using a fragment of the 16S rRNA gene. Three species of Anaplasma
were detected from R. microplus; Anaplasma marginale (19.08%), Anaplasma platys (1.97%) and unidentified
Anaplasma strain (0.66%). The infection rate of Ehrlichia was 7.24% (two ticks were infected with E. minasensis
(1.97%) and eight with an unidentified Ehrlichia strain (5.26%). No infections were found in R. sanguineus or
H. bispinosa. This is the first report of A. platys and E. minasensis in cattle ticks in Thailand, providing information
for future epidemiological surveys and control strategies in this region. |
