　　OBJECTIVE: To use nucleic acid detection technology to detect MHV, Reo-3 and MNV enteroviruses in cecal contents of mice, and to compare the results with serological detection results to analyze the applicability of nucleic acid detection in mouse health monitoring.

　　Methods: The cecal content samples of mice received in our laboratory were randomly selected, nucleic acid was extracted, and three kinds of enteroviruses, MHV, Reo-3 and MNV, were detected by fluorescence quantitative PCR technology; and their serological antibody detection results were correlated.

　　RESULTS: Among the 272 samples, the detection rates of MHV, Reo-3 and MNV were 17.3%, 18.8% and 16.9%, respectively. The correlation analysis of the serological antibody test results showed that the nucleic acid test results of the three viruses were not completely correlated with the antibody test results.

　　CONCLUSIONS: There is a possibility of carrying MHV and Reo-MNV in the experimental animal mouse population. As a supplement to the serological antibody detection technology, nucleic acid detection can be used as a highly sensitive method in the health monitoring of experimental animal populations.
