(ret'rō-vir'i-dē),
A family of RNA viruses 80-100 nm in diameter, enveloped, and containing two identical molecules of positive sense, single-stranded RNA, molecular weight 3-6 × 106; genomic RNA serves as a template for the synthesis of a complementary DNA, which may be integrated into the host DNA. At present, seven genera have been identified: Mammalian type B retroviruses, Mammalian type C retroviruses, Avian type C retroviruses, Type D retroviruses, BLV-HTLV retroviruses, Lentivirus, and Spumovirus.
