The serogroup/serotypes (SGTs) and antimicrobial susceptibilities to 10 antimicrobial agents of 110 clinical strains of Streptococcus pneumoniae were determined. Strains intermediately resistant or highly resistant to penicillin G (80 of 110) belonged predominantly to SGTs 23 (45.0%), 19 (13.7%), 6 (10.0%), 9 (6.2%), and 14 (3.7%). The MICs of all cephalosporins, tetracycline, trimethoprim-sulfamethoxazole, and chloramphenicol increased along with the MICs of penicillin G. However, erythromycin resistance and clindamycin resistance were observed more frequently among the intermediately penicillin-resistant strains. Multiple resistance was observed for 32 strains, of which 25 were highly resistant to penicillin G and belong to SGT 23F. All strains were susceptible to vancomycin.
测定了110株肺炎链球菌临床分离株的血清群/血清型(SGTs)以及对10种抗菌药物的药敏情况。对青霉素G呈中度耐药或高度耐药的菌株(110株中的80株)主要属于血清群/血清型23(45.0%)、19(13.7%)、6(10.0%)、9(6.2%)和14(3.7%)。所有头孢菌素、四环素、甲氧苄啶-磺胺甲恶唑和氯霉素的最低抑菌浓度(MIC)均随青霉素G的MIC升高而升高。然而,在中度青霉素耐药菌株中,红霉素耐药和克林霉素耐药更为常见。观察到32株多重耐药菌株,其中25株对青霉素G高度耐药且属于血清型23F。所有菌株对万古霉素均敏感。
