C. Doit et al., Emergence in France of multiple clones of clinical Streptococcus pneumoniae isolates with high-level resistance to amoxicillin, ANTIM AG CH, 43(6), 1999, pp. 1480-1483
The genetic relatedness of French isolates of Streptococcus pneumoniae high
ly resistant to amoxicillin (MIC, greater than or equal to 4 mu g/ml, equal
to or exceeding those of penicillin) was investigated by molecular fingerp
rinting. The results suggest that high-level resistance to amoxicillin has
emerged within preexisting penicillin-resistant clones.
