Abstract

OBJECTIVE

In this pilot study, we verified safe practices for breast milk expression, storage, and duration, based on bacteriological results.

RESULTS

We collected breast milk samples from three healthy lactating volunteers and analyzed the bacterial flora and changes in the viable bacterial counts (including those of Staphylococcus) of the samples. Although no consistent change could be observed in the abundance of a particular bacterial group in samples expressed under hygienic control conditions, viable bacterial counts were higher in self-expressed milk than in milk expressed under hygienic control conditions. In conclusion, increased hygiene awareness is vital during breast milk expression and storage.

摘要

目的

在这项初步研究中，我们根据细菌学结果验证了安全的母乳挤出、储存和保存时间的做法。

结果

我们从三位健康的哺乳期志愿者收集母乳样本，并分析样本的细菌菌群和活菌计数（包括葡萄球菌）的变化。虽然在卫生控制条件下挤出的样本中，特定细菌群的丰度没有观察到一致的变化，但自挤奶的活菌计数高于卫生控制条件下挤出的奶。结论：在母乳挤出和储存过程中，提高卫生意识至关重要。
