[Immunoelectroblotting in Mexican subjects at high risk for infection with human immunodeficiency virus (HIV)].
Sera from 124 persons in high risk groups were analyzed including homosexuals, blood recipients, and spouses or siblings from AIDS patients. In this study, 118 individuals had a positive ELISA for anti-HIV antibodies. Six persons had a complete immunodeficiency syndrome and a negative ELISA test. In the Western blot, 111 sera were positive, four negative, and nine scored indeterminate; four of the latter converted to positive when retested three months later. Antibodies present in the positive sera were directed against the HIV gp 41 kD in 100% of the cases and against the gp 120 kD in 82%. Frequency of recognition of p55 kD was 96% but p18 kD was only 42%.
