Murine herpesvirus 68 (MHV-68) is a natural pathogen that infects murid rodents, which serves as hosts for Ixodes ricinus ticks. For the first time, MHV-68 was detected in immature I. ricinus ticks feeding on Lacerta viridis lizards trapped in Slovakia, which supports the idea that ticks can acquire the virus from feeding on infected hosts. The recent discovery of MHV-68 infection and MHV-68 M3 gene transcripts in Dermacentor reticulatus ticks collected in Slovakia also supports this suggestion. Here, for the first time, we report MHV-68 infection, which was detected by nested PCR, in I. ricinus adults collected from the vegetation, and the viral load in infected ticks was determined by quantitative PCR. The viral incidence in ticks was 38.1% (21/55), and the viral load varied from 1.5 × 103 to 2.85 × 104 genome copies per tick. These results suggest that the I. ricinus ticks became infected with MHV-68 from biting infected rodents; thus, I. ricinus ticks may play a role in the spread of this virus in nature.
