초록

Enterobacteriaceae에 속하는 세균들은 보건학적 문제를 발생시키기도 하며 항생제 내성 병원균의 발생으로 인하여 자연환경 중의 항생제 내성균에 분포에 대한 관심이 증대되고 있다. 따라서 배양법을 이용하여 국내 5개의 하천시료로부터 그람 음성 Enterobacteriaceae의 종 다양성을 조사하였으며 분리된 세균에 대한 다제내성을 항생제디스크 확산법으로 분석하였다. 그 결과, 분리된 그람 음성 Enterobacteriaceae는 Citrobacter, Enterobacter, Escherichia, Klebsiella, Kluyvera, Pantoea, Plesiomonas, Raoultella, Shigella로 동정되었으며 49%가 Enterobacter로서 우점종으로 분석되었다. 또한 이들 세균들의 78.3%가 조사된 13종의 항생제 중에서 7종 이상에 내성을 보였으며 이것은 국내 자연하천환경에 높은 비율의 다제내성균이 서식한다는 것을 제시한다.

Enterobacteriaceae is one of the major families responsible for public health threats. Due to the emergence of pathogens with antibiotic resistance, great concern has been raised regarding the prevalence of antibiotic resistant bacteria in natural environments. Therefore, the diversity of Gram negative Enterobacteriaceae was investigated in water samples collected from five streams in Korea using the cultivation method. Profiling of multi-drug resistance was conducted with isolates via disk diffusion assay. The results indicated that the Gram negative Enterobacteriaceae consisted of the following genus; Citrobacter, Enterobacter, Escherichia, Klebsiella, Kluyvera, Pantoea, Plesiomonas, Raoultella, Shigella and Enterobacter. These latter strains represented 49% of identified isolates. In addition, 78.3% of the identified genus exhibited resistance against more than seven out of thirteen tested antibiotics, suggesting a high prevalence of multi-drug resistant bacteria in natural environments.
