To detect Streptococcus mutans in colostrum and saliva of neonates and compare with its detection in saliva of mothers.
Forty-three healthy women, full-term gestations with no complications, submitted to elective Cesarean section, and their newborns were included in the study. Samples were investigated by polymerase chain reaction to detect S. mutans in genetic material from the samples.
Approximately 16% of colostrum samples showed S. mutans , but not correlated with the presence of the bacteria in both samples of saliva. S. mutans was detected in 49 and 30% of saliva samples of mothers and neonates, respectively. There was a positive correlation in S. mutans detection between types of saliva. The number of maternal samples of saliva with detectable S. mutans was smaller in women receiving dental treatment during pregnancy. Tooth brushing, three times a day, influenced the detection of S. mutans in both the saliva and the colostrum.
Although maternal saliva may present S. mutans , few samples of colostrum present the bacteria. The presence of bacteria in neonate saliva may be related to contact before birth. Dental treatment and hygiene habits seem to influence the detection of S. mutans in samples of maternal saliva and colostrum.
检测新生儿初乳和唾液中的变形链球菌，并与母亲唾液中的检测结果进行比较。
43名健康女性，足月妊娠且无并发症，接受择期剖宫产，其新生儿纳入研究。通过聚合酶链反应对样本进行检测，以检测样本遗传物质中的变形链球菌。
约16%的初乳样本显示有变形链球菌，但与两份唾液样本中细菌的存在无关。母亲和新生儿唾液样本中变形链球菌的检出率分别为49%和30%。不同类型唾液中变形链球菌的检测存在正相关。孕期接受牙科治疗的女性中，可检测到变形链球菌的母亲唾液样本数量较少。每天刷牙三次会影响唾液和初乳中变形链球菌的检测。
虽然母亲唾液中可能存在变形链球菌，但初乳样本中很少有该细菌。新生儿唾液中细菌的存在可能与出生前的接触有关。牙科治疗和卫生习惯似乎会影响母亲唾液和初乳样本中变形链球菌的检测。
