摘要
用被动保护试验的方法，通过比较抗脂多糖（ＬＰＳ）血清组与ＬＰＳ中和抗鸡白痢血清组的ＬＤ５０，证明了ＬＰＳ的保护性作用。与攻菌对照组的ＬＤ５０相比，抗ＬＰＳ血清组有非常显著的差异（０．００２＞Ｐ＞０．００５），ＬＰＳ中和抗鸡白痢血清组有显著差异（０．０２＞Ｐ＞０．０５）。试验证明，ＬＰＳ是鸡白痢沙门氏菌（Ｓａｌｍｏｎｅｌａｐｕｌｏｒｕｍ）菌体主要的保护性抗原之一。
Through passive protection tests, the LD 50 of anti Lipopolysaccharide (LPS) sera was compared with that of anti Salmonella pullorum sera neutralized by LPS. Results showed that there were significantly differences in protective effect between anti LPS sera and normal controls (0.002>P>0.005),as well as anti S.pullorum sera and normal controls (0.02 >P>0.05). It is proved that LPS may be one of the prime protective antigen within S.pullorum.
