Susceptibility of bisexual and parthenogenetic Asian longhorned ticks to severe fever with thrombocytopenia syndrome virus (SFTSV), China. Groups of bisexual or parthenogenetic nymph Asian longhorned ticks were fed separately on 1 IFNAR^−/− (interferon α/β receptor knockout) C57/BL6 mouse that was intraperitoneal inoculated with 2 x 10³ focus-forming units of SFTSV. A) Viremias of IFNAR^−/− C57/BL6 mice were monitored by using real-time PCR during tick feeding. B) SFTSV infection in the Asian longhorned ticks were tested by real-time PCR after molting into adults. Each dot or square indicates 1 tick. Black horizontal bars indicate means. NS, not significant.
