Seroprevalence of HTLV-I/II in blood donors in Monterrey, México

The prevalence of antibiodies against human T-cell lymphotrophic virus (HTLV-I/II) in blood donors from the city of Monterrey, Mexico was investigated. We found that 4 out of 1017 sera (0.39 percent) reacted against HTLV-I/II, as determined by a passive agglutination test (PA). However, none of PA-positive sere reacted to HTLV-I/II specific polypeptides as demostrated by Western blot. These findings indicate that the population of Monterry has very low or no seroprevalence for HTLV-I/II
