Inefficient Mechanical Transmission of Langat (Tick-Borne Encephalitis Virus Complex) Virus by Blood-Feeding Mites (Acari) to Laboratory Mice
Abstract
One day after feeding on a viremic mouse, tropical rat mites, Ornithonyssus bacoti (Hirst), transmitted Langat (tick-borne encephalitis virus complex) virus to a naive suckling mouse in one of four trials. However, no transmissions to naive mice by O.bacoti were recorded either immediately after the viremic blood meal (0/4 trials) or on days 4-18 (0/20 trials). After feeding on viremic mouse, chicken mites, Dermanyssus gallinae (DeGeer), failed to transmit Langat virus to naive suckling mice in any trials (0/24). Although virus failed to replicate in either species of mite, it was detectable in 20% (2/10) of O. bacoti individuals 1 d after a viremic blood meal, but only immediately after the viremic blood meal in 20% (2/10)of D. gallinae mites. Neither mite appears to be an efficient vector of Langat virus
