The Epstein-Barr virus (EBV) belongs to the family of herpesviruses.1-1-1 With respect to morphology, EBV is hardly distinguishable from other family members. Based on pathogenesis, characteristics of replication, and host cell tropism, herpesviruses can be classified into three subfamilies: alpha-, beta-, and gamma-herpesvirus. EBV belongs to the genus Lymphocrypto-virus of gamma-herpesviruses, which are characterized by a narrow host (cell) range and a slow rate of replication in cell culture.
Depending on the type and the differentiation of the infected cell, EBV follows one of the two alternative strategies to survive: latent persistence or productive replication.1-2-1 During latency, no infectious progeny is released and expression of viral genes is tightly restricted. In comparison, at least 80 viral genes are activated in a timely coordinated manner during lytic productive replication.
