A strain of Salmonella of serotype Salinatis, that produced a mannose-resistant and eluting haemagglutinin (MREHA) when cultured at 37 degrees C but not at 18 degrees C, was examined by electron microscopy after negative staining. Production of this MREHA, previously described as being non-fimbrial, was correlated with the presence of thin fimbriae which had an external diameter of 3.6 nm. The purified Salinatis thin fimbriae had an estimated Mr of 19 kDa. This fimbrial MREHA was not produced by strains of the antigenically related serotypes Duisburg and Sandiego.
对一株血清型为萨利纳蒂斯的沙门氏菌进行了研究，该菌株在37℃培养时可产生一种抗甘露糖且能洗脱的血凝素（MREHA），但在18℃培养时则不产生。经负染后用电子显微镜对其进行了检查。这种先前被描述为非菌毛的MREHA的产生与外径为3.6 nm的细菌毛的存在相关。纯化后的萨利纳蒂斯细菌毛的估计分子量为19 kDa。抗原相关血清型杜伊斯堡和圣地亚哥的菌株不产生这种菌毛MREHA。
