Abstract

To obtain antibiotic resistant profiles of Bifidobacterium, minimum inhibitory concentrations (MIC) of 14 antibiotics for 93 Bifidobacterium isolates from Korean intestine origin were determined. All strains tested were sensitive to chloramphenicol, rifampicin, and amoxicillin, whereas resistant to aminoglycoside family, nalidixic acid, and vancomycin. Among vancomycin-resistant strains, 34% were resistant at more than $100\;{\mu}g/mL$, and showed variant resistances toward tetracycline, erythromycin, and penicillin. Their resistances against penicillin, cephalothin, and tetracycline were higher than ten years ago. MIC of ten isolates from commercial yoghurt products were very similar to those of strains from Korean intestine origin, and 20% strains showed resistance at higher than $100\;{\mu}g/mL$ vancomycin. These results indicated patterns of antibiotic resistance against Bifidobacterium from Korean intestine origin and commercial yoghurts were very similar,and prevalence of vancomycin resistance for Bifidobacterium was 20%. To develop new probiotic, antibiotic resistance of vancomycin and risks involved should be evaluated.

장내 상주균이며 probiotics로 활용되고 있는 Bifidobacterium에 대한 항생제 내성분포를 분석하였다. 분석된 93개의 Bifidobacterium이 chlolurnphenicol, rifampicin, erythromycin에 대해서는 감수성을 갖고 있었고, aminoglycoside계 항생제, nalidixic acid와 vancomycin에 내성을 갖는 것으로 나타났다. 그리고 vancomycin의 MIC가 $100\;{\mu}g/mL$ 이상인 균이 전체 균주 중 34%를 차지했다. Tetracycline, erythromycin, penicillin에 대한 내성은 매우 다양하게 나타났다. ${\beta}-lactam$계 항생제인 penicillin G와 cephalothin은 10년보다 더 내성이 높아졌음을 알 수 있었고, ampicillin, amoxicillin, tetracycline은 항생제 농도가 점차 증가하고 있는 것으로 보인다. 인체유래 분리균과 유산균식품 분리균의 항생제 내성은 대부분 비슷한 특성을 보였으나 유산균식품 분리 균주중 vancomycin의 MIC가 $100\;{\mu}g/mL$ 이상인 균주가 약 20%가 되는 것으로 나타났다. 따라서 새로운 probiotics를 개발하기 위해서는 이러한 항생제 내성 특성을 분석하고 항생제 내성 위해성에 대한 검증이 필요한 것으로 보인다.
