Experimental infection of Eurasian collared-dove (Streptopelia decaocto) with West Nile virus

J Vector Ecol. 2013 Dec;38(2):210-4. doi: 10.1111/j.1948-7134.2013.12032.x.

Abstract

The Eurasian collared-dove (Streptopelia decaocto) has recently experienced a population explosion in North America. It is frequently infected with West Nile virus (WNV). To test the hypothesis that the Eurasian collared-dove is competent to transmit WNV, we experimentally infected two cohorts of doves with two different strains of WNV, CO08, and NY99, respectively. Both virus strains induced a low-level viremia, capable of infecting a small fraction of vector mosquitoes. We suggest that the Eurasian collared-dove plays a relatively insignificant role as an amplifying host for WNV, but it may be important where it is locally abundant.

Keywords: Eurasian collared-dove; West Nile virus; amplification host; reservoir competence index; virus titer.
