Popis: | We surveyed group C and group G β-hemolytic streptococci for emm and emmL (emm -like) genes which encode the M protein, as well as determined their antimicrobial susceptibilities. A total of 97 isolates 79 GCS/GGS isolates and 18 isolates from other groups were tested for the M protein gene by PCR. Focusing on invasive infections with group A (GAS), group C (GCS), and group G (GGS) β-hemolytic streptococci isolated from blood, the M protein gene was found in 90.0%, 84.6%, and 78.3% of isolates, respectively. The hypervariable N terminal region of the emm was sequenced from 62 isolates, and 26 types of the emm gene were identified. Based on these results, type emm222.2 may be endemic to Thailand. The results of antimicrobial susceptibility testing of groups C, G, and non-groups A to G isolates indicated high susceptibility (range 82-100%) to penicillin, cefotaxime, chloramphenicol, clindamycin, erythromycin, linezolid, ofloxacin, and vancomycin, whereas the isolates showed low susceptibility (range 0-15.6%) to tetracycline. |
