Abstract
© 2018 The Author(s). Thogoto virus (THOV), a tick-borne arbovirus not previously reported in East Asia, was recently isolated from Haemaphysalis longicornis in Kyoto, Japan. In this study, we investigated the vector competence of H. longicornis ticks for a Japanese isolate of the Thogoto virus using anal pore microinjection and experimental virus acquisition. Our results showed that anal pore microinjection can readily infect adult ticks, and THOV-infected ticks can successfully transmit the virus to mice. Blood feeding was also critical in the distribution of the virus in tick organs, most especially in the salivary glands. Furthermore, co-feeding between an infected adult and naïve nymphs can also produce infected molted adults that can horizontally transmit THOV to mice. Altogether, our results suggest that H. longicornis is a competent vector for the Japanese THOV isolate and could be the primary tick vector of the virus in Japan.
