Abstract

Abstract: 【Objective】 The aim of this study was to investigate the species and genetic diversity of hard ticks from cattle and sheep in the China-Myanmar border region of Tengchong city,Yunnan province,and provide a basis for the prevention and control of diseases caused by them.【Method】 The present study conducted a survey on tick infection in cattle and sheep in four towns in Tengchong city from June to July 2024,the ticks were collected and submitted to morphological identification.The mitochondrial cox1 gene and ribosomal ITS2 gene sequences of 16 ticks (8 from cattle and 8 from sheep) were amplified by PCR,their genetic diversity,haplotype polymorphism and phylogenetic relationships were analyzed using DNAStar,Mega 7.0 and DnaSP software.【Result】 The farm positive rate of tick infection in cattle and sheep in the four investigated towns was 100% (24/24).The infection rates of ticks in cattle and sheep were 94.37% (64/71) and 91.74% (111/121),respectively.A total of 362 ticks were collected,all of which were identified as Rhipicephalus microplus through morphological analysis.The intraspecific differences in cox1 (762 bp) and ITS2 (1 477 bp) gene sequences of 16 R.microplus isolates were 0-0.5% and 0-1.3%,respectively.The similarity between cox1 and ITS2 gene sequences of R.microplus (branch C) in GenBank exceeded 99.5% and 99.0%,respectively.The haplotype diversity of cox1 and ITS2 genes was 0.858 and 0.932,respectively,while the nucleotide diversity was 0.00395 and 0.00514,respectively.The results of phylogenetic tree analysis revealed that all 16 R.microplus belonged to the same branch as known R.microplus,the isolates from different host sources were randomly distributed in this branch,but they were far away from the branches of other ticks.【Conclusion】 The prevalence of ticks on the surface of cattle and sheep in Tengchong city,Yunnan province was severe,and all ticks were R.microplus belonging to branch C.The R.microplus strains from different hosts had certain genetic variations,but the haplotype diversity and nucleotide diversity were low,and there was no genetic differentiation phenomenon.

Key words: cattle; sheep; Rhipicephalus microplus; cox1 gene; ITS2 gene; genetic evolution; haplotype diversity
