experimental transmission of karshi (mammalian tick-borne flavivirus group) virus by ornithodoros ticks >2,900 days after initial virus exposure supports the role of soft ticks as a long-term maintenance mechanism for certain flaviviruses.members of the mammalian tick-borne flavivirus group, including tick-borne encephalitis virus, are responsible for at least 10,000 clinical cases of tick-borne encephalitis each year. to attempt to explain the long-term maintenance of members of this group, we followed ornithodoros parkeri, o. sonrai, and o. tartakovskyi for >2,900 days after they had been exposed to karshi virus, a member of the mammalian tick-borne flavivirus group.201526285211
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 ...200415535630
