[Staphylococci in the microbiocenosis of the skin of the hands].
The skin autoflora on the pad of a forefinger and the back and palm of a hand was studied in 40 healthy males aged 18-60 years by the modified washing and scraping method of P. Williamson and A. Kligman. 638 cultures of aerobic microorganisms, including coccal (55.3%) and bacilliform (44.7%) microbes, were isolated. In 6 persons (15%) coagulase-positive staphylococci were detected. Out of 10 coagulase negative species of this genus, S. epidermidis, S. saprophyticus and S. warneri occurred most frequently on the skin of hands. The highest density of bacterial populations (10.970 +/- +/- 1.845 cells/sq. cm) was registered on the back of hands, the surface of palms was found to have somewhat lower density (8.679 +/- 1.282 cells/sq. sm) and the skin of forefingers, the lowest density of bacterial populations (6.878 +/- +/- 1.137 cells/sq. sm). 17.5% of examined persons were found to be carriers with S. aureus isolated from their nasal mucosa. S. aureus isolated from the skin surface and the nasal cavity of different persons belonged to different phage variants, but S. aureus isolated from the nasal cavity and the skin of the same person belonged to one phage variant.
