SEROPREVALENCE OF HTLV-I II IN BLOOD-DONORS IN MONTERREY, MEXICO/

The prevalence of antibodies against human T-cell lymphotrophic virus (HTLV-I/II) in blood donors from the city of Monterrey, Mexico was inv estigated, We found that 4 out of 1017 sera (0.39%) reacted against HT LV-I/II, as determined by a passive agglutination test (PA), However, none of PA-positive sera reacted to HTLV-I/II specific polypeptides as demonstrated by Western blot, These findings indicate that the popula tion of Monterrey has very low or no seroprevalence for HTLV-I/II.
