Abstract

This study was carried out to identify bacterial strains adhered to domestic pet dog hair and to identify antibacterial extracts from natural compounds. A total of 76 strains were isolated from dog hair. The most common species isolated was Staphylococcus spp. (41 isolates), followed by Micrococcus spp. (21 isolates), Enterococcus spp. (8 isolates), Bacillus sup. (3 isolates), Exiguobacterium sup. (2 isolates), Shigella spp. (1 isolate) and Zoogloea spp. (1 isolate). These results suggested that dog hair could be a source of bacterial contamination to human. The susceptibility of isolates to antibiotics and antibacterial activities of the natural compounds were examined by disk diffusion method. Water and ethanol extract from Scutellaria baicalensis revealed high antibacterial activities against Staphylococcus, Micrococcus, Enterococcus and Shigella. Our results suggest that the extract of Scutellaria baicalensis can be used a antibacterial agent against the antibiotic-resistant microorganisms.

애완견의 털에 부착되어 있는 세균을 분리 동정한 후, 이 분리 세균들에 대한 항세균효과가 있는 생약재 추출물을 탐색하였다. 애완견의 털에서 76개의 세균을 분리한 결과, Staphylococcus속이 41균주로 가장 많았으며 그 다음으로 Micrococcus속이 21균 주, Enterococcus속이 8균주, Bacillus속이 3균주, Exiguobacterium속 of 2균주, Shigella속과 Zoogloea속이 각각 1균주씩으로 동정되었다. 이러한 결과는 개의 털에 존재하는 세균들이 사람에게 감염을 일으킬 수 있는 원인이 될 수 있음을 시사한다. 분리균주들에 대한 항생제 저항성과 생약재 추출물의 항세균 활성은 디스크 확산법으로 확인하였다. 황금의 추출물이 애완견의 털로부터 분리한 세균들에 대해 높은 항세균 활성을 나타내어 항생제 저항성이 있는 세균들에 대한 새로운 항미생물제로 사용학 수 있을 것으로 기대된다.
