Epstein-Barr virus (EBV) infection in animal model systems has been studied previously in marmosets and tamarins using serology and PCR of saliva. Here we directly demonstrated long-term persistence of EBV in the peripheral blood of marmosets by assaying EBER RNA expression. A new reverse transcription-PCR assay, able to distinguish a naturally occurring strain polymorphism in EBER 2 that may be useful as a strain marker for monitoring persistence and interactions between multiple strains in the same animal or person, has been developed. In situ hybridization and immunohisto-chemistry have also been used to search for EBV-infected cells in the animals. The carrier state in the common marmoset is similar to that of humans in that it is asymptomatic, long-lived and displays a very low level of circulating virus-infected cells. It differs from the human in lacking the characteristic antibody response to EBNA 1.
