The O antigen is a polymer of oligosaccharide units. O antigens differ in their sugar composition and glycosidic linkages, and genes responsible for O-antigen-specific biosynthesis are grouped in the rfb gene cluster. In this study, we identified two abequosyltransferase genes and an acetyltransferase gene in Salmonella enterica groups B and C2 by in vitro assay and identified paratosyl-, tyvelosyl-, and abequosyltransferase genes from S. enterica groups A and D and Yersinia pseudotuberculosis serovar IIA, respectively, by comparison.
O抗原是寡糖单元的聚合物。O抗原在其糖组成和糖苷键方面存在差异,负责O抗原特异性生物合成的基因聚集在rfb基因簇中。在本研究中,我们通过体外试验在肠炎沙门氏菌B群和C2群中鉴定出两个阿比可糖基转移酶基因和一个乙酰转移酶基因,并通过比较分别从肠炎沙门氏菌A群和D群以及假结核耶尔森氏菌血清型IIA中鉴定出对甲苯磺酰基、泰威糖基和阿比可糖基转移酶基因。
