A. N. Afanasyev. On the issue of post-natal microorganisms. (Protocol of the meeting of the Obstetric and Gynecological Society in Kiev, book 7, 1894, p. 79)

The author investigated the allocation of 29 puerperas, out of whom in 20 postnatal period proceeded correctly and in 9 with complications. The selection was studied on various days of the post-birth period. For collecting lochies from various sections of the genital canal, the author came up with his own device. Lochies were examined under a microscope, were grafted into animals and fed on nutrient media. Microscopic studies have shown that postnatal compartments in the vast majority of cases contain microbes in a greater or lesser amount and variety of forms.
