Vibrio mimicus strains W-26768 (stool isolate) and N-1301 (environmental isolate) and Vibrio fluvialis strains AA-18239 (stool isolate) and M-940 (environmental isolate) were studied for virulence properties and lipopolysaccharide composition. All four strains were hydrophobic, produced cytotoxin, adhered to HeLa cells and showed mannose-sensitive agglutination of guinea pig erythrocyte. The strains were negative for enterotoxin production and were mostly susceptible to the common antibiotics. The environmental and clinical isolates of both species were antigenically unrelated to each other. Lipopolysaccharide antigen analysis showed that O-antigen polysaccharides of two strains of V. fluvialis and two strains of V. mimicus differed with respect to the sugar components. Only LPS from V. mimicus W-26768 showed the presence of an unusual sugar, 3,6-dideoxy-3-acetamido-hexose. The sugar compositions of these V. fluvialis and V. mimicus strains differed from those of previously reported Japanese isolates. These differences probably reflect differences in the serogroup of strains.
对模仿弧菌菌株W-26768（粪便分离株）和N-1301（环境分离株）以及河流弧菌菌株AA-18239（粪便分离株）和M-940（环境分离株）的毒力特性和脂多糖组成进行了研究。所有这四株菌都具有疏水性，能产生细胞毒素，可黏附于HeLa细胞，并对豚鼠红细胞表现出甘露糖敏感凝集反应。这些菌株不产生肠毒素，且大多对常用抗生素敏感。这两个菌种的环境分离株和临床分离株在抗原性上互不相关。脂多糖抗原分析表明，两株河流弧菌和两株模仿弧菌的O抗原多糖在糖成分方面存在差异。只有模仿弧菌W-26768的脂多糖显示存在一种不寻常的糖，即3,6-二脱氧-3-乙酰氨基己糖。这些河流弧菌和模仿弧菌菌株的糖组成与先前报道的日本分离株不同。这些差异可能反映了菌株血清群的差异。
