Antibody detection from Middendorf's vole (Microtus middendorffii) against Tula virus captured in Mongolia.

Mongolia in 2010 and 2011. A total of 76 voles belonging to the genera Myodes and Microtus were captured. Most of the voles that were seropositive to Tula virus antigen were Middendorf's voles (Microtus middendorffii (6/31)). Two of the 18 Myodes voles were also seropositive to Tula virus antigen. On the other hand, only one vole was seropositive to Puumala virus antigen. The results suggest that Tula virus was maintained in Middendorf's vole. This is the first report of detection of anti-Tula virus antibody in the central part of the Eurasia continent.
