Research in the department is directed to investi- gations of biological characterization and pathogenesis of the following viruses; diarrhea viruses (Norovirus, Sapovirus, etc.), enteroviruses, poxviruses, tumor viruses (papillomaviruses, polyomaviruses, etc.) and hepatitis viruses. Tumorigenesis in relation to viral infection is also studied in the department. Develop- ments of new vaccines and diagnostics for these viral diseases are included in the main lines of research. Research projects using various viral vectors (baculovirus, adenovirus, vesicular stomatitis virus, vaccinia virus etc.) are on going. The department is assigned for both national- and international reference laboratories.
