초록

다제내성균의 증가는 사용할 항생제가 적거나 심지어 선택할 항생제가 없기 때문에 감염환자의 치료에 커다란 위협이 되고 있다. 최근 다양한 천연 추출물이 내성세균에서 항균효과 및 상승효과를 보인다는 보고가 많다. 어성초(Houttuynia cordata)는 항균, 항바이러스 및 항산화 효과를 보이는 전통적 약초이다. 이에 저자들은 임상의 주요 내성균에 대한 어성초의 항균효과를 알아보고, 이들의 적절한 항균효과 측정방법을 평가하고자 한다. 우선 현재 가장 많은 문제를 야기하는 주요 내성균인 methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant Enterococcus faecium (VRE), carbepenem-resistant Acinetobacter baumannii(CRAB) 각각 10 균주를 선택하여, CLSI 기준으로 디스크 확산법 및 미량액체배지희석법으로 감수성 시험을 하였다. CLSI 기준으로 시행한 디스크 확산법에서 $4,096{\mu}g/mL$에서 $30,000{\mu}g/mL$ 까지의 농도에서 모든 균의 억제대는 관찰되지 않았다. 그러나 액체배지 희석법에서는 MRSA, VRE, CRAB의 $MIC_{90}$이 각각 $4,096{\mu}g/mL$, $8,192{\mu}g/mL$, $4,096{\mu}g/mL$를 보였다. 결론적으로 어성초는 MRSA, VRE, CRAB 등 주요 임상 내성균에서 우수한 항균효과를 보이며 천연물의 항균효과를 평가에 디스크 확산법보다 액체배지 희석법이 유용하다고 할 수 있다. 만약 디스크 확산법으로 항균효과를 측정하려면 천연물에 대한 균 접종 농도의 변경 등 새로운 기준이 요구된다.

The increase in resistance by pathogenic bacteria to multiple antimicrobial agents has become a significant treat, as the effective antimicrobial agents available for the patients infected by such resistant bacteria are reduced, or even eliminated. Several natural plant extracts have exhibited antibacterial and synergistic activity against various resistant microorganisms. Houttuynia cordata is frequently used by many traditional medicine practicioners for its antimicrobial, antiviral, and anti-inflammatory properties. This study investigated the antibacterial effects of H. cordata extract against clinical multi-resistant bacteria, and compared the two methods used for the antimicrobial susceptibility testing. Thirty isolates of Methicillin-resistant Staphylococcus aureus (MRSA, 10), Vancomycin-resistant Enterococcus faecium (VRE, 10), Carbapenem-resistant Acinetobacter baumannii (CRAB, 10) were included in this study. The antibacterial effect of H. cordata was tested by disk diffusion and microbroth dilution methods as per CLSI guidelines. In disk diffusion, all isolates (30) showed no inhibition to 30,000 ug/mL of H. cordata. But in the microbroth dilution method, $MIC_{90}$ of H. cordata was 4,096 ug/mL, 8,192 ug/mL and 4,096 ug/mL in MRSA, VRE and CRAB, respectively. These results demonstrate that H. cordata exhibits antibacterial activity against MRSA, VRE and CRAB. Moreover, the microbroth dilution method is a more effective method than disk diffusion to evaluate the antibacterial activity of natural products. The Disk diffusion method used to evaluate the antibacterial activity of natural products required new standard guidelines including inoculum concentration of bacteria.
