West Nile Virus and High Death Rate in American Crows
We document effects of West Nile virus (WNV) on American Crows. More than two thirds of our crows died of WNV infection, peaking when the proportion of infected mosquitoes at roosts was greatest. WNV antibody prevalence in crows was low. Local ecologic effects can be dramatic as WNV inhabits new areas.
متن کاملWest Nile Virus Detection in American Crows
A dipstick immunochromatographic assay used for West Nile virus (WNV) detection in mosquitoes was investigated for application to testing of fecal, saliva, and tissue samples from dead American Crows (Corvus brachyrhynchos). Results suggest that VecTest may be an efficient method for WNV detection in field-collected, dead American Crows, although confirmation of results and further investigatio...
متن کاملGender Determination and Lack of Sex-Specific West Nile Virus Mortality in American Crows
With a set of external measurements from a sample of known-sex American crows (Corvus brachyrhynchos) in central Illinois, we determined whether a published discriminant function for sex determination was applicable to crows in a different geographic location than the reference sample. Low classification success with this equation, likely due to geographic size differences in crows between regi...
متن کاملWest Nile virus quantification in feces of experimentally infected American and fish crows.
To better understand the potential environmental health risk presented by West Nile virus (WNV)-contaminated feces, we quantified the amount of WNV present in the feces of experimentally infected American crows (Corvus brachyrhynchos) and fish crows (Corvus ossifragus). Peak fecal titers ranged from 10(3.5) to 10(8.8) plaque-forming units (PFU)/g for 10 American crows and from 10(2.3) to 10(6.4...
متن کاملDifferential Virulence of West Nile Strains for American Crows
Crow deaths were observed after West Nile virus (WNV) was introduced into North America, and this phenomenon has subsequently been used to monitor the spread of the virus. To investigate potential differences in the crow virulence of different WNV strains, American Crows were inoculated with Old World strains of WNV from Kenya and Australia (Kunjin) and a North American (NY99) WNV genotype. Inf...
