The heterogeneity of the cell wall O-polysaccharide of Salmonella zuerich (factor 1 present or absent) is probably not due to mutations in the stock since it was seen in essentially similar fashion (proportion one 1+ to four 1-forms) in four separate lots of polysaccharide extracted from separate culture batches. The results of indirect fluorescent antibody studies suggest that form variation of factor 1, occurring at an unusually high rate, is the most probable basis of the heterogeneity.
苏黎世沙门氏菌细胞壁O-多糖的异质性(因子1存在或缺失)可能并非源于菌株中的突变,因为从不同培养批次提取的四批多糖中,均以基本相似的方式观察到了这种异质性(比例为1个1+型对4个1-型)。间接荧光抗体研究结果表明,因子1以异常高的频率发生形态变异,这很可能是异质性的基础。
