淡水養殖香魚之Vibrio病病原菌Vibrio anguillarum之分離
Vibrio Anguillarum Isolated from a Vibrio Disease of Fresh-Water Cultured Ayu, Plecoglossus Altivelis
摘要
1975年本省桃園地區淡水養殖之香魚大量死亡，由罹病魚分離出一種Gram stain陰性，大小為1~2μ×0.5μ之短桿菌，略呈弧形，具有端單鞭毛，運動性極强之Vibrio anguillarum。本菌之肉眼觀察之發育溫度及鹽分為5~35℃及0~7%，對多種藥物具有抗性，但對chloramphenicol及tetracycline具有高感受性。病原性試驗顯示本菌對香魚及泥鰍具有極强之病原性，由接種魚出現之症狀可推斷本菌為淡水養殖香魚大量死亡之病原菌。

In the present investigation a vibrio was isolated from fresh-water cultured diseasedayu, Plecoglossus altivelis. On the basis of biochemical characteristics, it was identified as Vibrio anguillarum. The organism was euryhaline, i. e., it could grow well in the culture media containing 0%-7% NaCl. As far as pathogenicity was concerned, it produced symptoms of red disease in ayu and loach by experimental infection. The isolated strain was highly sensitive to chloramphenicol and tetracycline.
