DictionarySeeretrovirusRetroviridae
Retroviridae[‚re·trə′vir·ə‚dī] (virology) A family of ribonucleic acid (RNA)-containing animal viruses characterized by spherical enveloped virions containing two single-stranded RNA molecules and reverse transcriptase, includes the subfamilies Oncovirinae, Spumavirinae, and Lentivirinae. Retroviridae
Ret·ro·vir·i·dae (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.Ret·ro·vir·i·dae (ret'rō-vir'i-dē) A family of viruses grouped in three subfamilies: Oncovirinae (HTLV-I, HTLV-II RNA tumor viruses), Spumavirinae (foamy viruses), and Lentivirinae (HIV-like viruses, visna, and related agents). |
