Objective To examine infection prevalence of severe fever with thrombocytopenia syndrome virus (SFTSV) in domestic animals in Pulandian district of Dalian city, Liaoning province.
Methods We selected two townships with SFTSV infection cases reported between 2015 and 2017 as the survey sites. Then we collected blood samples from domestic animals at the two sites during 2017. Double antigen sandwich enzyme-linked immunosorbent assay (ELISA) was adopted to detect serum immunoglobulin G (IgG) antibody against SFTSV.
Results The overall positive rate of serum IgG antibody against SFTSV was 52.89% for 346 blood samples of domestic animals and the positive rate was 85.23% for 88 samples of sheep, 64.63% for 82 samples of cattle, 21.59% for 88 samples of dog, and 40.91% for 88 samples of chicken. There were significant differences in the positive rate of dog and sheep samples collected in different townships and from the dogs and sheeps at various month of age.
Conclusion Environment for poultry and livestock rearing should be improved and tick population needs to be controlled with insecticides for the prevention and control of SFTSV infection.
