 AB    Lymphocytes and monocytes from 25 patients infected with human
       immunodeficiency virus type-1 (HIV-1)--13 asymptomatic, seven with the
       AIDS-related complex (ARC) and five with the acquired immunodeficiency
       syndrome (AIDS)--were lysed and subjected to PCR with three primer
       pairs: SK38/SK39 (gag), SK68/SK69 (env) and SK29/SK30 (LTR). Amplified
       DNA was solution-hybridised with 32P-labelled probes (SK19, SK70 and
       SK31, respectively) and detected by PAGE-autoradiography. HIV-1 DNA was
       detected as follows. Asymptomatic patients: monocytes--gag 61.5%, env
       100%, LTR 0%; lymphocytes--gag 100%, env 92.3%, LTR 53.84%. ARC
       patients: monocytes--gag 71.4%, env 57.1%, LTR 0%; lymphocytes--gag
       100%, env 71.4%, LTR 71.4%. AIDS patients: monocytes--gag 80.0%, env
       100%, LTR 0%; lymphocytes--gag 100%, env 60%, LTR 60%. The presence of
       HIV-1 DNA was confirmed in the monocyte fraction. In this cell subset,
       the env gene-directed primers were the most effective for amplification,
       whereas the LTR gene-directed primers failed to amplify HIV-1 DNA. The
       different pattern of amplification found in monocytes may suggest that
       these cells could be infected by a genetic variant of the virus.
