Abstract: Abstract: To establish a PCR assay for detection of murine cytomegalovirus ( MCMV) ． Provide help for the purification of MCMV． Sequence of MCMV was obtained from NCBI Genbank． One pairs of primers were designed based on this sequence． The primers was determined through amplifying the major strains in China． Eighty-seven mice serum were tested with this PCR assay． The positive amplified fragments were sequenced to verify the reliability of this method． A PCR method for detection of MCMV is successfully established，with a high specificity and sensitivity． Among the tested 87 blood samples， 13 positive cases were detected． Sequencing of the samples are consistent with the amplification results，and verified the applicability of this detection method． The establishment of this method provides the basis for detection of MCMV in mice，and application of this assay in mouse．
