Table 1.
TULV seroprevalence in common vole populations in four German areas from 2010 to 2013. Seroprevalence (%) in spring, summer and autumn of each year was estimated for three replicate grassland sites per area based on live and snap trapping. Values for the number of positive tested individuals (positive/total) per season are given for all sites in each study area. Percentages were calculated only for sites with ≥5 tested individuals (otherwise NA = not applicable).
