Research from Wildlife Research Center provides new data about west nile virus

New research, 'Persistent West Nile virus infection in the house sparrow (Passer domesticus),' is the subject of a report. According to recent research from the United States, "Long-term persistence of West Nile virus (WNV) infection within vertebrate reservoir hosts is a potential mechanism for overwintering of this (and other) arbovirus(es) at temperate latitudes. The house sparrow (Passer domesticus), an established amplifying host for WNV and other arboviruses, was used as a model to confirm chronicity of WNV infection in passerine birds and to evaluate the feasibility of two overwintering mechanisms: blood-borne infection of arthropod vectors (recrudescence) and oral infection of...
