Plain-English summary
In August 2014, a 9-year-old female horse in Turkey had to be put down after showing serious health problems, and tests revealed that she had a strain of West Nile virus (WNV) known as lineage 2 in her brain. Further analysis showed that this strain was similar to ones found in Greece between 2010 and 2012. Among other horses in the area, some had antibodies indicating they had been exposed to the virus, while others showed no signs of the virus in local mosquito populations. Overall, this case provides the first evidence of this particular strain of West Nile virus being present in Turkey.
Abstract
In August 2014, a West Nile virus (WNV) strain belonging to lineage 2 was detected in the brain tissues of a 9 year old mare euthanised after showing severe clinical signs in Bursa region, Turkey. Phylogenetic analyses of 290 bp of NS3 coding region clustered the Turkish strain together with the 2010-2012 Greek isolates. Either IgG and IgM or IgG only WNV antibodies were detected in 2 and 11 horses, respectively, which were in the outbreak surrounding. No WNV RNA was detected in pools of 50 individuals of Culex pipiens (n = 2), Ochlerotatus caspius (n = 2), and Culex theileri (n = 1) collected in the infected premises.
