Abstract

Imipenem-resistant bacteria were isolated from clinical specimens taken from hospitalized patients in Suncheon, Korea. Fifty-four isolates were phylogenetically analyzed based on 16S rRNA gene and gyrB gene sequence comparisons. Isolates were affiliated with Pseudomonas aeruginosa (30 strains; 55.6%), Acinetobacter baumannii (21; 38.9%), Enterobacter hormaechei (2) and Pseudomonas putida (2). Twenty-two isolates produced metallo-$\beta$-lactamase (MBL); 12 Acinetobacter baumannii strains, 7 Pseudomonas aeruginosa strains, 2 P. putida strains and 1 Enterobacter hormaechei strain. Antibiotic susceptibility of the isolates was determined using the disc diffusion method and Vitek system. Strains producing metallo-$\beta$-lactamase (type IMP & VIM) were more resistant to antibiotics ceftazidime, aztreonam, amikacin and gentamicin than to strains producing OXA and SHV type of $\beta$-lactamase.

대한민국 순천의 병원 입원 환자의 검체로부터 imipenem 내성 세균을 분리하였다. 54개의 분리균을 16S rRNA 유전자와 gyrB 유전자 염기서열 비교를 기초로 하여 계통분류학적으로 동정하였다. 분리균들은 Pseudomonas aeruginosa (30균주; 55.6%), Acinetobacter baumannii (21; 38.9%), Enterobacter hormaechei (2)와 Pseudomonas putida (2)에 속했다. 22개의 균주가 metallo-$\beta$-lactamase (MBL)를 생산하였으며 종별 구성은 다음과 같다; Acinetobacter baumannii 12균주, Pseudomonas aeruginosa 7균주, P. putida 2균주 그리고 Enterobacter hormaechei 1균주. 분리균들의 항생제 감수성은 디스크 확산법과 Vitek 을 이용하여 조사하였다. IMP 와 VIM 형의 metallo-$\beta$-lactamase를 생산하는 균주들은 OXA 와 SHV 형 $\beta$-lactamase를 생산하는 균주들에 비해 ceftazidime, aztreonam, amikacin과 gentamicin에 대한 내성율이 높았다.
