Abstract

Field isolates of herpesviruses recovered from falcon, pigeon, and psittacine birds were compared by restriction endonuclease (RE) analysis using four separate enzymes. Pigeon and falcon herpesviruses had strikingly similar DNA cleavage patterns, while DNA cleavage pattern of virus isolates from a double-yellow headed Amazon and an African grey parrot had different genomic patterns to both the pigeon and falcon herpesviruses. These findings support the field observations that pigeon herpesvirus causes a fatal herpesviral infection in the livers of pigeon-eating falcons.

摘要

使用四种不同的限制性内切酶，通过限制性内切酶（RE）分析比较了从猎鹰、鸽子和鹦鹉鸟类中分离出的疱疹病毒野外分离株。鸽子和猎鹰疱疹病毒具有惊人相似的DNA切割模式，而从双黄头亚马逊鹦鹉和非洲灰鹦鹉分离出的病毒株的DNA切割模式与鸽子和猎鹰疱疹病毒的基因组模式均不同。这些发现支持了野外观察结果，即鸽子疱疹病毒会在捕食鸽子的猎鹰肝脏中引发致命的疱疹病毒感染。
