RESUMO
Using the ELISA technique, cytomegalovirus [CMV] IgG and IgM values were measured in the sera of 176 subjects who delivered healthy term infants and in the cord sera of the newborn babies. IgG was positive in 149 of 176 maternal sera and in 6 of 176 newborn cord sera. The subjects were classified into three socioeconomic levels: high, moderate and low. The distribution of IgG and IgM positivity among the three groups revealed significant differences [p <0.05]. The fetus and the placenta are affected during primary and reactive infections in pregnancy. The percentage of IgM-positive infants delivered by IgM-positive patients was found to be highly significant. CMV IgG is not always protective against reinfection. In our study, IgM was positive in 24 women in spite of IgG positivity. The distribution of CMV seropositivity was not significan is important risk factors in pregnancy as it is the most frequent congenital and early postnatal infectious agent
