Unique ID: D015498
RDF Unique Identifier: http://id.nlm.nih.gov/mesh/D015498
Annotation: infection: coord IM with HIV INFECTIONS (IM) or AIDS (IM) or their specifics (IM)
Scope Note: An HIV species related to HIV-1 but carrying different antigenic components and with differing nucleic acid composition. It shares serologic reactivity and sequence homology with the simian Lentivirus SIMIAN IMMUNODEFICIENCY VIRUS and infects only T4-lymphocytes expressing the CD4 phenotypic marker.
