The concentration of secretory IgA and the levels of IgA specific antibodies against Escherichia coli labile-toxin, Shigella flexneri 6, and rotaviruses were determined in milk samples obtained serially from women during the first 16 weeks postpartum. The mean concentration of secretory IgA followed the expected pattern; the levels of specific antibodies fluctuated in an unpredictable manner and independently of milk secretory IgA content, becoming undetectable in many instances. Under some circumstances, continued breast-feeding may not guarantee continued intake of antibodies against intestinal pathogens by the breast-fed infant.
测定了产后16周内从女性身上连续采集的乳汁样本中分泌型IgA的浓度以及针对大肠杆菌不耐热毒素、福氏志贺菌6型和轮状病毒的IgA特异性抗体水平。分泌型IgA的平均浓度符合预期模式；特异性抗体水平以不可预测的方式波动，且与乳汁分泌型IgA含量无关，在许多情况下无法检测到。在某些情况下，持续母乳喂养可能无法保证母乳喂养的婴儿持续摄入针对肠道病原体的抗体。
