어병 세균에 대해 쑥(Artemisia princeps var. orientalis) 추출물인 정유의 항균성을 조사하였다. Aeromonas hydrophila, Aeromonas salmonicida, Aeromonas sorbia, Edwardsiella tarda 와 Streptococcus sp. (yellowtail)는 1,000~2,000 ppm 에서 증식이 억제되었다. 즉 억제 농도는 A.salmonicida 가 1,000 ppm A.hydrophila, A. sorbia, E. tarda 와 Streptococcus sp. (yellowtail)는 1,500 ppm 이었다. 그러나 Vibrio anguillarum, Vibrio ordalii, Edwardsiella ictaluri와 Streptococcus sp. (SF-1)는 100~2,000 ppm 농도에서 현저한 억제 효과는 없었다.
The antimicrobial activity of Artemisia princeps var. orientalis essential oil against a partial fish pathogenic bacteria was examined. The growth of Aeromonas hydrophila, Aeromonas salomonicida, Aeromonas sorbia, Edwardsiella tarda and Streptococcus sp. (yellowtail) were inhibited at concentrations of 1,000 to 2,000 ppm. The A. salmonicida was inhibited at 1,000 ppm, A. hydrophila, A. sorbia, E, tarda and Streptococcus sp. (yellowtail) at 1,500 ppm, but Vibrio anguillarum, Vibrio ordalii, Edwardsiella ictaluri and Streptococcus sp. (SF 1) were grown on 100-2,000 ppm.
