Abstract:
To investigate the prevalence of severe fever with thrombocytopenia syndrome virus (SFTSV) in quest and fed ticks in Yanbian area,Jilin province,we collected ticks from 8 counties (cities) from Yanbian area and submitted to test through real time RT-PCR targeting M segment of SFTSV after morphological identification.Bi-directional sequencing were also performed on the amplicons to conduct phylogenetic analysis.As the results,from April to September 2016,a total of 3 446 ticks,including 763 Dermacentor silvarum,222 Haemaphysalis concinna,639 Hae.japonica,515 Hae.longicornis,1 014 Ixodes persulcatus,were harvested.Among 1 605 ticks tested,the minimal infection rate was 8.65% for Hae.concinna,4.53% for Hae.japonica,1.59% for Hae.longicornis,and 3.2% for Haemaphysalis spp.respectively.Sequence analysis from 1 pool of Hae.longicornis showed that M segment of the SFTS viruses shares highly homologous (99%) with those isolated from patients in other provinces of China.Phylogenetic analyze showed that the SFTSV belongs to the same branch with those isolated from patients in Zhejiang Province (2012),and from Hae.longicornis infested on patients in Korea (2013) The SFTS virus obtained from Hae.longicornis in Yanbian area,Jilin,was proposed as YBHC-tick1-Jilin/China.
