Mouse cytomegalovirus reactivation in severe combined immune deficient mice after implantation of latently infected salivary gland.

Journal Article

The hypothesis that replication-competent mouse cytomegalovirus (MCMV) is detectable in severe combined immunodeficient (scid) mice after implantation of latently infected tissue was examined. Sections of latently infected salivary gland from 5 BALB/c mice were implanted into 20 C.B-17 scid mice. Recipient scid mice were sacrificed weekly for 5 weeks, and MCMV infection was detected in target organs using culture and DNA polymerase chain reaction (PCR). All donors were negative by standard culture but positive by DNA PCR. Replicating MCMV was recovered from 9 of 15 recipient scid mouse salivary gland, lung, liver, or spleen samples at postoperative weeks 2-5. No virus was recovered from recipient scid mice at weeks 1 or 12. Transplantation of latently infected tissues into scid mice resulted in rapid reactivation and dissemination of the virus. Further study of this model promises insight into the mechanisms of CMV latency and reactivation.
