The survival of group B streptococci on a variety of swabs, held either in their containers or in transport media for periods of up to 48 hours, at room temperature and at 4 degrees C, has been assessed. Results indicated that holding swabs in transport media did not favour prolonged survival of the streptococci and that the yield of organisms was much greater from swabs held in their ordinary plastic tubes. A holding temperature of 4 degrees C rather than room temperature is recommended if any delay in plating out swabs is anticipated.
