Modification of aminoglycoside antibiotics by clinical isolates of Streptococcus faecalis.

Abstract
Clinical isolates of S. faecalis contain streptomycin (SM)-phosphotransferase, kanamycin (KM)-acetyltransferase and KM-adenylyltransferase. The existence of a new type of KM-phosphotransferase was suggested from aminoglycoside substrate profiles.
