Epidemiologic and experimental data support the notion that Ljungan virus (LV), endemic in some rodent populations in Sweden, Denmark, and the United States, can cause morbidity and mortality in animals and humans. LV infection can cause type I diabetes mellitus, myocarditis, and encephalitis in ban

Abstract
The Ljungan virus (LV), a member of the Parechovirus genus and Picornaviridae family was isolated originally from its wild reservoir, the bank vole (Myodes glareolus) at the Ljungan River in central Sweden [Niklasson et al., 1999]. LV is associated with diseases such as myocarditis, encephalitis, pregnancy related diseases, and diabetes in several species of wild rodent [Niklasson et al., 2006a]. The same outcomes can be induced in mice under controlled laboratory conditions [Niklasson et al., 2006b]. Several mouse and rat animal models used to study diabetes have been found to carry LV naturally [Niklasson et al., 2007]. The role of the viruses in diabetes pathogenesis has been investigated by treating these animals with antiviral compounds [Holmberg et al., 2009].
Variation in the incidence of type 1 diabetes has been found to track the fluctuations in native rodent populations in central Sweden. Increased prevalence of antibodies to LV has been detected in Swedish type 1 diabetes cases. However, LV virus has not been isolated and its viral RNA has not been detected in type 1 diabetes. J.
