 AB    Nine patients with atypical HIV-1 western blot profiles were diagnosed
       as having HIV-1 subtype O infection. All the patients were living in
       France; eight originated from Cameroon and one from France. Lymphocyte
       DNA amplification by the polymerase chain reaction was only positive
       when HIV-1 subtype O specific primers were used. Preliminary sequence
       analysis of amplified products and serological reactivity against a
       specific subtype O synthetic env peptide confirmed HIV-1 subtype O
       infection. HIV-1/HIV-2 enzyme-linked immunosorbent assays, especially
       those based on env peptides or on the sandwich format, can be negative
       in HIV-1 subtype O infection.
