[A study of sera positive and doubtful for antibodies to the human immunodeficiency virus for the presence of HTLV-I-specific antibodies].

The results of examinations for the presence of antibody to HTLV-I of 205 sera which were positive or indefinite (doubtful) with regard to HIV are presented. No evidence indicating simultaneous infection with HIV and HTLV-I viruses in 18 HIV-positive subjects was obtained. Antibodies to gag-proteins p19 and p28 HTLV-I were detected in one serum showing primary reactivity in screening for HIV antibodies.

[Increase in the specificity of immunoenzyme analysis by using a monoclonal antibody-based conjugate].

Examinations by EIA of laboratory cultures of various orthopoxviruses and specimens from human-monkey pox cases demonstrated the advantages of a monoclonal preparation over the peroxidase polyclonal conjugate prepared from hyperimmune vaccinia antiserum.
