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.

摘要

海鸟软蜱（Carios capensis，蜱螨目：argasidae科）最初采集于美国佐治亚州沿海地区，让其吸食感染西尼罗河病毒（WNV）的北京鸭（Anas domesticus）的血液。经过35天的外潜伏期后，这些蜱将病毒传播给了未感染的小鸭。在侵染后7天，通过蚀斑试验和逆转录聚合酶链反应（RTPCR）在蜱以及小鸭的组织和血清中检测到了西尼罗河病毒。
