| experimental transmission of langat (tick-borne encephalitis virus complex) virus by the soft tick ornithodoros sonrai (acari: argasidae). | laboratory studies determined that the soft tick ornithodoros sonrai sautet & witkowski is a competent vector of langat (tick-borne encephalitis virus complex) virus. when ticks fed on suckling mice having a mean viremia of 10(7.2) plaque-forming units per ml, 52% (n = 208) became infected, and 84% (n = 87) of the infected ticks transmitted virus by bite when fed individually on suckling mice > or = 27 d after the infectious blood meal. overall, 79 of 184 (43%) of ticks exposed to the original v ... | 1994 | 8158617 |
| experimental transmission of karshi and langat (tick-borne encephalitis virus complex) viruses by ornithodoros ticks (acari: argasidae). | selected species of mosquitoes and ornithodoros ticks were evaluated for their potential to transmit karshi and langat (tick-borne encephalitis virus complex) viruses in the laboratory. although there was no evidence of replication of karshi virus in either of the two mosquito species tested [ochlerotatus taeniorhynchus (wiedemann) or culex pipiens (l.)], karshi virus replicated in and was transmitted by all three species of ornithodoros ticks tested (ornithodoros parkeri cooley, ornithodoros so ... | 2004 | 15535630 |
