[Prospective means of decreasing suppurative-septic diseases in puerperae and newborn infants].

The comparative analysis of the occurrence of purulent septic diseases in mothers during the puerperal period and in newborns, observed in a maternity hospital before and after the introduction of the system of keeping newborns together with their mothers, showed a considerable decrease in the morbidity rate among newborn infants (6 times) and in occurrence of mastitis among puerperae (30 times). This is attributed to a decrease in the frequency of the colonization of newborns and mothers in the puerperal period by the hospital strains of staphylococci belonging to epidemic phagotypes. The gradual elimination of staphylococci of phagotype 80, which dominated for several years, from the hospital was observed.
