La. Thal et al., TN924, A CHROMOSOME-BORNE TRANSPOSON ENCODING HIGH-LEVEL GENTAMICIN RESISTANCE IN ENTEROCOCCUS-FAECALIS, Antimicrobial agents and chemotherapy, 38(5), 1994, pp. 1152-1156
Enterococcus faecalis SF350 is a clinical isolate from Winnipeg, Canad
a, with high-level (MIC > 2,000 mu g/ml) gentamicin resistance. The ge
netic determinant for gentamicin resistance was located on the chromos
ome of SF350 and could be mobilized by a coresident conjugative plasmi
d, pYN120. Genetic and physical analyses showed that the gentamicin re
sistance determinant was located on a 27-kb transposable element which
was designated Tn924.
