Exposure of Wildlife to the Schmallenberg Virus in France (2011-2014): Higher, Faster, Stronger (than Bluetongue)!

摘要: Summary The Schmallenberg virus (SBV) has recently emerged in Europe, causing losses to the domestic livestock. A retrospective analysis of serodata was conducted France for estimating seroprevalence SBV among six wildlife species from 2011–2012 2013–2014, that is during three vector seasons after emergence France. Our objective quantify exposure and potential protective effect elevation such as previously observed bluetongue. We also compared spatiotemporal trends between wild animals at level departments. tested 2050 sera using competitive ELISA tests. Individual population risk factors were further general linear models 1934 individuals. All populations but one exhibited positive results, up 30% being all species. average did not differ ranged 0 90% according area period, due dynamic pattern infection. Seroprevalence on higher lowlands areas located 800 m. Nevertheless, above 50% occurred 1500 Thus, contrary what had been bluetongue late 2000s same areas, could spread high altitudes infect studied spatial fully match with outbreaks reported mismatch most obvious mountainous where year peak congenital cases These results suggest a much larger capacity than natural areas. Potential consequences dynamics are discussed.
