				        	Objective To define dynamic changes of viral loads and antibody responses in ICR mice naturally infected with hepatitis virus in an MHV contaminative facility .Method A total 50 ICR were housed by different “dirty bedding” exposure.Antigen and antibody was detected after 2,4,8,14,21,28,35,42,56 and 84 days.Result Mouse hepatitis virus (MHV) was detected in lung after 2 days, and positive rate is 20% (1/5).MHV was detected in lung, liver, cecal and feces during 4 and 56 days.The positive rate was 0/5 in lung, liver, cecal and feces on 84 days after experiments.Antibody positive rates were 100%during 8 and 84 days.Conclusion Serological method can be used as the main method for the diagnosis of the daily supervision , and antigen detection method can only be applied to early diagnosis .
