Eradication of murine norovirus from a mouse barrier facility.
Year: 2008
Type: article
Abstract: Murine norovirus (MNV) is a common viral infection of mice in many research facilities. MNV infects hematopoietic cells and alters their cellular morphology. Because of MNV's probable effects on the systemic immune response of infected mice the decision was made to eradicate the virus from 2 rooms containing infected animals in our vivarium. Two different eradication methods were selected. One room, in which most of the indirectly exposed sentinels had antibodies to MNV, was depopulated and thoroughly cleaned prior to repopulation. In the other room, in which only 13% of the sentinels had positive MNV titers, selective testing was used, and MNV-positive animals were removed. Data from surveillance of the sentinel mice exposed to dirty bedding indicate that the test-and-removal method was ineffective in eliminating MNV from the room, whereas sentinel mice in the room that underwent depopulation and cleaning prior to repopulation have not shown any evidence of MNV since December 2006.
