Seroconversion 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.

Wild bird carcasses were collected through passive monitoring of wild bird mortality. In necropsy, brain samples were taken from dead wild birds in 2010, 2011 and 2012. Samples were used for detection of West Nile virus by reverse transcriptase-polymerase chain reaction (RT-PCR). No WNV nucleic acid was detected by RT-PCR. In the light of the data presented there is no evidence of wild bird mor...
متن کاملWest Nile virus-neutralizing antibodies in wild birds from southern Spain.
West Nile virus (WNV) is an emerging vector-borne arbovirus with a zoonotic life-cycle whose main reservoir hosts are birds. In humans and horses, WNV infections rarely result in clinical disease but on occasions - depending on factors such as climatic conditions, insect communities and background immunity levels in local populations - they can lead to outbreaks that threaten public and animal ...
متن کاملWest Nile Virus Antibodies in Wild Birds, Morocco, 2008
To determine circulation of West Nile virus (WNV) during nonepidemic times, we serosurveyed wild birds of Morocco in 2008. We found antibodies against WNV in 12 (3.5%) birds, against Usutu virus in 1 (0.3%), and against both in 2 (0.6%). High WNV prevalence among juvenile birds suggests local virus circulation among resident birds.
متن کاملExperimental Infections of Wild Birds with West Nile Virus
Avian models of West Nile virus (WNV) disease have become pivotal in the study of infection pathogenesis and transmission, despite the intrinsic constraints that represents this type of experimental research that needs to be conducted in biosecurity level 3 (BSL3) facilities. This review summarizes the main achievements of WNV experimental research carried out in wild birds, highlighting advant...
