title: [Population characteristics and biological properties of micrococci colonizing the skin of the breasts].
abstract: As shown in this investigation, the population characteristics of micrococci inhabiting the skin of the mammary glands make it possible to regard these microorganisms as the permanent members of microbiocenosis. Their proportion among all isolated strains was, respectively, 27.2% and 27.7% for nulliparous and pregnant women and their occurrence, 96.7% and 92.1%. The largest population of micrococci was registered at the nipple area of both left (934-1,956 colony-forming units per sq. cm) and right (1,092-2,134 colony-forming units per sq. cm) breasts. A decrease in the number of micrococci was observed at the above-mentioned areas during pregnancy, which was accompanied by changes in the specific and antagonistic profiles of the association. This occurred supposedly under the necessity of preserving its dynamic stability.
