CAPSULAR TYPES AND ANTIMICROBIAL RESISTANCE OF STREPTOCOCCUS-PNEUMONIAE ISOLATED IN KOREA

The capsular types and the MICs of penicillin G and other antimicrobia l agents were determined for 89 isolates of Streptococcus pneumoniae. MICs of penicillin G ranged from 0.015 to 2 mg/l, with 29 % and 48 % o f the isolates exhibiting intermediate resistance and complete resista nce, respectively. All isolates were susceptible to teicoplanin and va ncomycin, but 81 % and 43 % of the penicillin G-resistant strains were intermediately resistant to cefotaxime and imipenem, respectively. St rains belonged to 16 different capsular types: 73 % belonged to types 19F and 23F, and 97 % of strains belonging to these two types exhibite d either intermediate or complete resistance to penicillin G.
