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.
