研究了从病鱼中分离的弧菌对真鲷皮肤粘液的粘附动力学。计算了改良的Langmuir吸附等温线，所得结果表明，除溶藻弧菌（CAN）表现出比例吸附动力学外，供试菌株（溶藻弧菌DP 1HE 4和鳗弧菌样DC 12 R8和DC 12 R9）表现出饱和动力学。皮肤粘液的粘附能力似乎不是致病性弧菌菌株的重要毒力因子，因为这种特定的相互作用取决于几个环境因素，温度和盐度是最重要的。然而，粘液对病原微生物缺乏抑制作用，以及弧菌菌株利用粘液作为碳源的能力，可能会影响它们在皮肤上的沉积，从而有可能感染养殖的应激鱼。
The kinetics of adhesion of Vibrio strains isolated from diseased fish to skin mucus of gilt-head sea bream was studied. A modified Langmuir adsorption isotherm was calculated, and the results obtained indicate that the strains tested (Vibrio alginolyticus DP1HE4 and Vibrio anguillarum-like DC12R8 and DC12R9) showed a saturation kinetics except for V. alginolyticus (CAN), which showed a proportional adsorption kinetics. The adhesive capability for skin mucus does not seem to be an essential virulence factor of pathogenic strains of Vibrio, since this specific interaction depended on several environmental factors, temperature and salinity being the most important. However, the absence of an inhibitory effect of mucus on the pathogenic microorganisms, and the capability of the Vibrio strains to utilize mucus as a carbon source, could factor their settlement on the skin with a potential for infection of cultured, stressed fish.
