[Features of contamination of the environment by Staphylococcus aureus carriers].

The specific features of the spread of S. aureus from carriers indoors were studied. In this study S. aureus cells were most frequently isolated from the floor, less frequently from the walls and furniture and even less frequently from the air. S. aureus were detected on environmental objects as early as 30 minutes after the carrier stayed and breathed in the room. The contamination of environmental objects increased when the carrier spoke loudly and made such respiratory acts as coughing and sneezing. After the carrier left the room the contamination of the environmental objects persisted for at least 14 hours (the term of observation), gradually decreasing. The degree of the contamination of environmental objects was inversely related to the distance of these objects from the carrier. The contamination of the environment was shown to be directly related to the concentration of S. aureus in the nasal cavity of carriers.
