Abstract
The effect of lincomycin on growth and hemolysin production by Staphylococcus epidermidis and Staphylococcus haemolyticus is presented. Lincomycin at subinhibitory concentration, clearly inhibited hemolysin yield without appreciably altering final growth density. The cells of these two microbes previously grown in the presence of lincomycin showed very low hemolytic activities upon disruption. The mode of lincomycin action on hemolysin production is discussed.
