Comments: Five serogroups of lentiviruses are recognised, reflecting the hosts with which they are associated (primates, sheep and goats, horses, cats, and cattle). The primate lentiviruses are distinguished by the use of CD4 protein as receptor and the absence of DU. Some groups have cross-reactive gag antigens (e.g., the ovine, caprine and feline lentiviruses). Antibodies to gag antigens in lions and other large felids indicate the existence of other viruses related to FIV and the ovine/caprine lentiviruses.
Virus infects vertebrates.
Description is on taxonomic level of genus. Virus belongs to the family Retroviridae (VC 61. ).
Total genome length is of one monomer 9200 nt. Genome sequence has terminal repeated sequences; long terminal repeats (LTR) (of about 600 nt. The 5' end of the genome has a cap. Cap sequence of type 1 m7G5ppp5'GmpNp. 3' end of each monomer has a poly (A) tract; 3'-terminus has a tRNA-like structure (and accepts lysin). Encapsidated nucleic acid solely genomic. 2 copies packed per particle (held together by hydrogen bonds to form a dimer).
Genomic nucleic acid not infectious.

ICTVdB - The Universal Virus Database, developed for the International Committee on Taxonomy of Viruses (ICTV) by Dr Cornelia Büchen-Osmond, is written in DELTA. The virus descriptions in ICTVdB are coded by ICTV members and experts, or by the ICTVdB Management using data provided by the experts, the literature or the latest ICTV Report. The character list is the underlying code. All virus descriptions are based on the character list and natural language translations from the encoded descriptions are automatically generated and formatted for display on the Web.
