Parvoviruses remain one of the most common viral infections seen in laboratory mouse colonies. The purpose of this study was to develop an antemortem polymerase chain reaction (PCR) assay to detect mice infected with mouse parvovirus-1 (MPV) and mice minute virus (MMV) using faecal samples. The MMV PCR assay consistently detected as few as 100 plasmid copies of MMV in faecal samples, while the MPV PCR assay detected as few as 10 plasmid copies of MPV. Faecal pellets from infected mice held at room temperature from 1 to 7 days tested positive by MMV and MPV PCR, respectively. This demonstrates that parvovirus DNA is stable in faecal samples kept at room temperature. PCR assays were also used to follow the length of MMV and MPV shedding in faeces from SENCAR mice, which were endemically infected with multiple agents. MMV faecal shedding was detected in 60-70% of the mice 5-7 weeks old, and by 13 weeks of age, faecal samples from all mice were negative for MMV. MPV faecal shedding was detected in 90-100% of the mice 5-11 weeks old; however, by 19 weeks of age, faecal samples from all mice were negative for MPV. These findings confirm that faecal shedding occurs for a limited time and suggest that 5-9-week-old mice are the most appropriate age group in endemically infected mice for faecal testing by MMV and MPV PCR.
