Identification of Haemaphysalis longicomis and Rhipicephalus microplus / 中华流行病学杂志

ABSTRACT

Objective To establish a method combined morphology and molecular marker for identifying Haemaphysalis longicomis and Rhipicephalus microplus. Methods Ticks were collected from domestic animals and wild environment in epidemic area of Hubei and Henan provinces where cases of fever with thrombocytopenia syndrome were prevalent. We classified the ticks by morphology characteristics before 12S rDNA of ticks were amplified by PCR and subsequently sequenced. Phylogenetic tree was constructed by PAUP4.0. Results The ticks belonged to Haemaphysalis longicomis and Rhipicephalus microplus through observation and analysed by the morphological characteristics of the ticks. 12S rDNA was cloned and sequenced while data confirmed the morphological identification of the results. Conclusion The method based on morphology that combined with molecular marker seemed a good method for the identificaton of ticks.
