Intracellular replication of the non-lytic single stranded circular DNA mycoplasmavirus MVL51 has been shown to involve three DNA intermediates: RFI, RFII and SSI. Growth in Eagle's basal medium, rather than richer tryptose medium, has allowed the identification of an intermediate between nascent progeny chromosomes (SSI) and mature virus. This intermediate is a protein associated form of SSI.
