Objective To investigate the expression of murine cytomegalovirus (MCMV) M83mRNA in mouse testes at the different periods of MCMV infection and its relationshipwith the severity of testicular lesionsMethods Used digoxin-labeled MCMV mRNA oligonucleotide probe, the mousetesticular tissues at the different periods following MCMV inoculation were detectedby in situ hybridization(ISH). The average absorbency (A) of ISH positive signalsrepresented the resticular MCMV load. The expression of MCMV M83 mRNA in theinfected testes and its relation with the severity of testicular lesions were analyzed.Results At different periods after MCMV inoculation, the expression of MCMV M83mRNA was detectable in the testicular tissues. The ISH positive signals were mainlylocated in cytoplasm of the testicular interstitial cells. The average A values at d 9after MCMV infection were the highest (comparison between the experimental groups,P<0.001). There were pathological inflammatory changes to varying degrees inseminiferous epithelia and interstitial cells at the different periods of infection, especiallyduring d 6 to d 9.Conclusion In testicular MCMV infection, the levels of MCMV M83 mRNA wererelated with the severity of testicular lesions, suggesting the dynamic detection of MCMVM83 mRNA could evaluate the prognosis of MCMV infection.
