Morphological comparison of Machupo with lymphocytic choriomeningitis virus: basis for a new taxonomic group.

abstract：:In order to study primate lentivirus evolution in the Colobinae subfamily, in which only one simian immunodeficiency virus (SIV) has been described to date, we screened additional species from the three different genera of African colobus monkeys for SIV infection. Blood was obtained from 13 West African colobids, and...

Upon infectious entry into a host cell, this genome is converted into a covalently closed superhelical form (CCC-DNA), which later serves as the template for transcription.
