Antibody Prevalence of West Nile Virus in Birds, Illinois, 2002
نویسندگان
چکیده
Antibodies to West Nile virus were detected in 94 of 1,784 Illinois birds during 2002. Captive and urban birds had higher seropositivity than did birds from natural areas, and northern and central Illinois birds' seropositivity was greater than that from birds from the southern sites. Adult and hatch-year exposure rates did not differ significantly.

Changes in seroprevalence of West Nile virus across Illinois in free-ranging birds from 2001 through 2004.
Of the 5,236 birds sampled for antibodies to West Nile virus (WNV) in Illinois from 2001 through 2004, 348 (6.6%) birds were seropositive. Our multiple year surveillance identified several avian species that had particularly high percentages of seropositive individuals. The importance of these species in the enzootic and/or epizootic transmission of WNV is discussed relative to their regional a...

Abstract Background and Objective: West Nile virus (WNV) is a member of the genus Flavivirus that can cause viral infections in human. This study aimed at detecting IgG antibodies against WNV in patients of two cities of Neka and Shiraz. Material and Methods: the participants were 46 possible WNV case from Neka (13 women and 10 men) and Shiraz (10 women and 13 men). IgG assay was ...
متن کاملSeroconversion in Wild Birds and Local Circulation of West Nile Virus, Spain
A serosurvey for neutralizing antibodies against West Nile virus (WNV) in common coots (Fulica atra) was conducted in Doñana, Spain. Antibody prevalence was highest in 2003, intermediate in 2004, and lowest in 2005. Some birds seroreverted <1 year after first capture. Seroconversion of birds suggests local circulation of the virus.
متن کاملWest Nile Virus Antibody Decay Rate in Free-ranging Birds.
Antibody duration, following a humoral immune response to West Nile virus (WNV) infection, is poorly understood in free-ranging avian hosts. Quantifying antibody decay rate is important for interpreting serologic results and for understanding the potential for birds to serorevert and become susceptible again. We sampled free-ranging birds in Chicago, Illinois, US, from 2005 to 2011 and Atlanta,...
متن کاملPrevalence of West Nile virus in migratory birds during spring and fall migration.
To investigate the role of migratory birds in the dissemination of West Nile virus (WNV), we measured the prevalence of infectious WNV and specific WNV neutralizing antibodies in birds, principally Passeriformes, during spring and fall migrations in the Atlantic and Mississippi flyways from 2001-2003. Blood samples were obtained from 13,403 birds, representing 133 species. Specific WNV neutrali...
