The O antigen is a bacterial surface polysaccharide made up of repeats of a short oligosaccharide. There are about 60 forms of O antigen in Salmonella, and genetic analysis indicates that these were acquired by interspecific gene transfer.
O抗原是一种由短寡糖重复序列组成的细菌表面多糖。沙门氏菌中有大约60种O抗原形式,基因分析表明这些是通过种间基因转移获得的。
