中文摘要 | 由台北近郊分離出一株能寄生於Aeromonas hydrophila 的噬菌弧菌,經多次重複單離,並做電子顯微鏡觀察鑑定後將其定名為Bdellovibrio A-1,並探討影響賓主關係的因子。噬菌弧菌產生的最是溫度為25~29度C,最是酸鹼值為pH 6.5 ,噬菌弧菌的生長需要添加二價陽離子Ca2+ 和 Mg2+ 。噬菌弧菌對三種魚病細菌均會造成感染,而宿主細菌的添加濃度以4*10較適合於噬菌弧菌的生長。 |
英文摘要 | One stain of bacteria parasite-Bdellovibrio was isolated from cultured fish ponds in Taiwan. This stain is able to parasitize on Aeromonas hydrophila, designated as Bdellovibrio A-1. The morphology of host and parasite were examined by means of electron microscopy. The effect of medium composition, initial pH of medium, incubation temperature, addition of divalent cation and kinds and concentration of host bacteria on the growth of Bdellovibrio were investigated. The optimum temperature for the growth of Bdellovibrio in liquid medium was 25-29 C. the optimum initial pH of medium was pH 6.5. growth of the parasite was dependent. Upon the addition of Ca2+ and Mg2+. The highest lytic action of Bdellovibrio was obtained by using a higher concentration of fish pathogenic bacteria (4 10 cells/ml) as host. |
