[Drug resistance of hospital strains of Staphylococcus epidermidis belonging to different biological types].

A total of 567 strains of Staph. epidermidis isolated from the bacteria carriers in several surgical units were studied. The cultures were typed according to the method developed by the authors. Their resistance to 12 antibiotics, mercuric chloride and cadmium sulphate was determined. Comparison of the strain biotypes and their drug resistance showed in some cases statistically significant correlation. It should be especially noted that staphylococci with pronounced polyresistance (simultaneous resistance to 7--12 antibiotics) prevailed among the strains belonging to biotypes 1 and 3.
