    A persisting type of infection with wasting syndrome was established in congenitally athymic nude mice after intraperitoneal inoculation with a mouse hepatitis virus which was not fully pathogenic for heterozygous haired littermates. From the liver, spleen, lymph nodes, and brain of most infected nude mice, the virus was detected at high titers during aperiod from 6 to 35 days postinfection, occurrence of degenerative and necrotic lesions being correlated with virus titers in these organs. The titer of serum neutralizing antibody remained undetectable or very low in most diseases nude mice, whereas some animals resisting the infection could produce antibody at a later stage. In heterozygous haired mice, some lesions were detectable at a very early stage of infection in the spleen and liver, but they seemed to disappear with a marked elevation of the neutralizing antibody titer. Nude mice were able to resist the virus infection when they had previously received transfer of thymocytes from weanling heterozygous littermates.
