Experimental Transmission of West Nile Virus( Flaviviridae: Flavivirus ) by Carios capensis Ticks from North America

Abstract

Seabird soft ticks, Carios capensis (Ixodida: Argasidae), originally collected from coastal Georgia, USA, were allowed to ingest a blood meal from pekin ducklings (Anas domesticus) infected with WNV. After 35 days of extrinsic incubation, the ticks transmitted virus to naive ducklings. WNV was detected via plaque assay and RTPCR in ticks and in tissues and serum of ducklings 7 days post infestation. Vector-Borne Zoonotic Dis. 5, 293–295.
