One hantavirus (Saaremaa virus, SAAV) seropositive<jats:italic>A. agrarius<\/jats:italic>, and 2 cowpoxvirus (CPXV) seropositive<jats:italic>S. araneus<\/jats:italic>were detected, and antibodies against an arenavirus (Lymphocytic choriomeningitis virus, LCMV) were found in all 3 mouse species but not in shrews. Cyst forms of<jats:italic>Pneumocystis<\/jats:italic>spp. were detected in all species except<jats:italic>A. agrarius<\/jats:italic>. There was no significant association between virus antibodies (LCMV in mice, and CPXV in shrews) and cyst forms of<jats:italic>Pneumocystis<\/jats:italic>in any of the species. Concurrent presence of virus antibodies (LCMV) and cyst forms of<jats:italic>Pneumocystis<\/jats:italic>were detected only in 1<jats:italic>M. minutus<\/jats:italic>.
