| Abstract;We examined the adhesion of Tenacibaculum sp., the causative bacterium of spotting disease of short-spined sea urchin Stronglycentroutus intermedius, to the host. The number of adhesive cells of Tenacibaculum sp. strain F-2 isolated from diseased sea urchin was about 30 times more than those of two stains of non-pathogenic marine Cytophaga sp. isolated from healthy sea urchins. The adhesion of Tenacibaculum sp. F-2 to the sea urchins was inhibited by about 90% when the sea urchins were pre-treated with 0.1% D-galactose or D-xylose for 1 h. With this treatment, all sea urchins remained asymptomatic and were still alive at 7'th' day after being immersed with 10'6' or 10'7' CFU/mL Tenacibaculum sp. F-2 for 1h at 23.DEG.C., while mortality of control reached 100%. These results indicate that carbohydrate treatment of the sea urchin is useful to control the disease. (author abst.) |
