title: [Parasitic and viral marker detection in pregnant adolescents and their newborn infants at risk].
abstract: We have investigated the prevalence of antibodies against Toxoplasma gondii, Trypanosoma cruzzi, Hepatitis B virus, cytomegalovirus, rubella virus, and human immunodeficiency virus in 139 adolescent pregnant women and in their high risk newborn children. The methods employed were the Sabin and Feldman reaction, complement fixation reaction, ELISA, and xenodiagnostic 30.9% of the pregnant group were seropositive for T. gondii, both mothers and newborns were IgM-negative. Two mothers (1.4%) presented anti T. cruzii antibodies, and one newborn child had circulating parasites. Related to the virological studies, 93.5% of the population were anti CMV antibodies positive and all their newborns were IgM (-) 90.6% of the adolescents were rubella positive and one was seropositive to VIH. We conclude that the prevalence found in this group of adolescent pregnant women are not significantly different to the one reported for the general pregnant women population.
