“…밀집되거나 산업 공단이 밀집되어있는 지역의 하 천은 항생제를 포함한 다양한 오염 물질들이 유입되며, 하수 처리장의 침전물 및 유출수가 유입되는 등 항생제 내성균의 하천 유입 가능성과 항생제 감수성균의 내성획득 기회가 상 대적으로 높다. 국내에서는 강원도와 수도권인구의 주요 상 수원으로 이용되는 한강 유역에서 채수한 시료로부터 분리한 Enterococcus 76종의 20%에 해당하는 15종이 VRE인것으로 보고된 바 있다(Kwon et al, 2012;Su et al, 2014). 전 세계적으로 항생제 내성균의 증가가 주요 안건으로 부 각됨에 따라, 내성에 대한 안전 관리를 위해 미국과 일본에서 는 NARMS (National antimicrobial resistance monitoring system)과 JVARMS (Japanese veterinary antimicrobial resistance monitoring system) 같은 광범위한 내성균 감시시스템을 확립 하여 내성균 모니터링을 실시하고 있다(Hur et al, 2012).…”

The widespread emergence of antibiotic resistant microorganisms in clinics and natural environments has attracted public concern. Especially, microorganisms inhabiting natural environment is considered as a source responsible for increasing the abundance of antibiotic resistant genes in ecosystem. In this study, the diversity of culturable bacteria resistant to ampicillin was investigated with water samples collected from seven locations in Korea. The genera belonging to Aeromonas and Acidovorax were dominant among the isolated 498 strains. The 66% of isolates showed multi-drug resistance against more than six antibiotics among tested fourteen ones and isolates resistant to seven antibiotics were the most prevalent with 19.7% abundance. Using the antibiotics susceptibility results, the intrinsic resistance profile was suggested for the most dominant genera, Aeromonas, Acidovorax, Pseudomonas, and Elizabethkingia.

Objectives: This study aims to understand the concentration, diversity, and antibiotic characteristics of oxytetracycline resistant bacteria present in a surface water environment. Methods:Water sampling was performed in Cheongmi Stream in Gyeonggi-do, Korea in February and August 2014. Water samples collected from two sites were plated in triplicate on tryptic soy agar plates with 30 mg/L of oxytetracycline. Oxytetracycline resistant bacteria were selected from surface water in Cheongmi Stream and were subjected to 16S rDNA analysis for oxytetracycline resistant species determination. Identified resistant strains were tested for resistance to various antibiotics. Results:Results from this study indicate that the dominant resistant organisms in this aquatic environment are from family Acinetobacter and family Aeromonas. As to culturable heterotrophic bacteria, Oxytetracycline resistant bacteria were present 0.45-0.93% during winter and 0.08-0.38% during summer. Most oxytetracycline resistant bacteria exhibited resistance to more than ten of the antibiotics studied. The diversity of oxytetracycline resistant bacteria in winter was higher than in summer.Conclusion: Most of these resistant bacteria are Gram negative and are closely related to pathogenic species. These results suggest that increasing multi-antibiotic resistant bacteria in the surface water environment has a close relation to the reckless use of antibiotics in livestock.
