Pr. Hsueh et al., High incidence of erythromycin resistance among clinical isolates of Streptococcus agalactiae in Taiwan, ANTIM AG CH, 45(11), 2001, pp. 3205-3208
The in vitro susceptibilities of 266 isolates of Streptococcus agalactiae d
etermined by the agar dilution method showed that 6% of isolates were nonsu
sceptible to penicillin and 46% was resistant to erythromycin. Of the eryth
romycin- resistant isolates, 86.3% had the macrolide-lincosamide-streptogra
m in (MLS) resistance phenotype (constitutive MLS, 85.5%; inducible MLS, 0.
8%) and 13.7% had the M phenotype.
