Auto-Infection from Vaginal Secretions
The normal vaginal secretion is antiseptic by virtue of its lactic acid content. The cervical secretion, on the other hand, is neutral or alkaline and forms an admirable culture medium for bacterial growth. Since the acidity of the vaginal secretion disappears during the puerperium, it seems a wonder that infection does not always occur. After experiments, Professor Marinescu concludes that the vaginal secretions during the puerperium destroy organisms by phagocytosis, and that bacteria existing in the passages before parturition can gain a foothold in the tissues only if the passages are injured during labor.
