In 80 apparently healthy pregnant women and their newborns tested for toxoplasmosis through the dye-test (RSF) greater than or equal to 1:16, were found respectively 50% and 38.7% positives. The positive mothers had positive newborns. The major part with the same titers as their mothers or one titer lower. The negative mothers had negative healthy newborns with one exception, considered "false positive reaction". The great majority of positive newborns were found negative at the 8th month, and the other until the 12th month. It's emphazised that the maternal and the newborn serology must be done at the same time. This considerations should be remembered when asymptomatic newborns with positive serology for toxoplasmosis are discussed.
在80名表面健康的孕妇及其新生儿中，通过染色试验（RSF）检测弓形虫病，滴度大于或等于1:16的，孕妇和新生儿的阳性率分别为50%和38.7%。阳性母亲所生新生儿也呈阳性。大多数新生儿的滴度与其母亲相同或低一个滴度。阴性母亲所生新生儿健康且为阴性，但有一个例外被视为“假阳性反应”。绝大多数阳性新生儿在8个月时转为阴性，其他的则直到12个月时转为阴性。需要强调的是，母婴血清学检测必须同时进行。在讨论弓形虫病血清学阳性的无症状新生儿时应牢记这些注意事项。
