Objective To investigate the distribution and species of ticks and rodents that were involved in the transmission of severe fever with thrombocytopenia syndrome(SFTS). Methods SFTS that occurred at Yaoshang village, Guangfu town, Wuzhong district of Suzhou city was investigated. The free ranging ticks were collected by flagging and the parasitic ticks were collected off the hosts by hand from June 14th to 18th in 2016. Small mammals were captured by cage-trapping. The specimens of serum,heart, liver, spleen, lung, and kidney were collected with sterile operations. The severe fever with thrombocytopenia syndrome virus(SFTSV)nucleic acid in the viscera of small animals and in the ticks were detected by real-time PCR. Results A total of 100 ticks were collected, consisting of 4 species, including 37.00% Haemaphysalis sinensis, 29.00% H. flava and 26.00% H. longicornis, separately, which composed the predominant species in Suzhou city. The total number of captured small animals was 17, including 3 species rodents, 1 species Erinaceidae and 1 species insectivora. The results were negative in RNA detection of SFTSV in the specimens of ticks and small animals by real-time PCR. Conclusion The tick vectors and the host animals of SFTSV were found in Suzhou city, but the transmission mechanism between the vectors and the possible hosts need further studies.
