Title: A survey on murine gammaherpesvirus 68 in ticks collected in Slovakia

Abstract: Murine gammaherpesvirus 68 (MHV-68) is a natural pathogen that infects murid rodents which serve as hosts for Dermacentor reticulatus and Ixodes ricinus ticks. For the first time, MHV-68 was detected in immature I. ricinus ticks feeding on lizards trapped in Slovakia. Later on, MHV-68 infection was detected in D. reticulatus and Haemaphysalis concinna ticks collected on vegetation, which supported the idea that ticks can acquire the virus from feeding on infected hosts. Here, we report MHV-68 infection, which was detected by nested PCR, in D. reticulatus and I. ricinus adult ticks and I. ricinus nymphs collected in five geographically isolated localities, in west, southwest, south and central Slovakia. Viral incidence in ticks was 46.7% (121/259) without considering the season, site of collection and tick species and their life stage. MHV-68 infection was detected in all five localities investigated and in both tick species. Here, for the first time, we report MHV-68 infection in I. ricinus nymphs collected from the vegetation. The finding of virus in ticks from five separated localities suggested that ticks became infected with MHV-68 via feeding on infected rodents; thus, this virus might be a newfound natural pathogen in ticks.
