摘要

According to serologic testing, murine norovirus is the most prevalent viral pathogen in contemporary laboratory mice. Previously, murine norovirus 1 (MNV-1) was the only norovirus reported to infect research mice. In this study, 3 novel murine norovirus strains--MNV-2, MNV-3, and MNV-4--were isolated from geographically separate mouse research colonies. All 4 murine norovirus strains used as individual antigens in microsphere fluorescent immunoassays displayed serologic cross-reactivity to serum from mice inoculated with MNV-1, MNV-2, MNV-3, or MNV-4. In addition, reverse transcriptase-polymerase chain reaction analysis at 8 wk postinoculation detected virus in the feces and tissues of all mice experimentally inoculated with MNV-2, MNV-3, or MNV-4. This finding suggests that mice can have prolonged fecal shedding of and can become persistently infected with murine noroviruses.
