Using the indirect hemagglutination test, antibodies against Enterobacteriaceae common antigen (CA) were tested in the sera of 123 horses, 142 cows, 108 sheep, 142 mature pigs and 60 piglets (3-4 weeks of age). Anti CA antibody level and antibody titers for somatic antigens (phenol-water extracts) various serogroups of E. coli (0149, 0138, 0115, 078, 09) and S. typhimurium were compared. Ca antibodies in titer equal or higher than 1:15 were found to occur in 100% of the examined horses and cows, while in the sera of 92% sheep, 80% of mature pigs and 60% of piglets antibodies to the common Enterobacterial antigen were present in titer equal or higher than 1:7.5. In all sera examined the antibody level to somatic antigens of E. coli and S. typhimurium exceeded that to Enterobacteriaceae common antigen. The influence of absorption of sera with CA preparation on the antibody level to heterologous antigens was also examined. It was found that the absorption caused a statistically significant decrease of the titers to O antigens E. coli and S. typhimurium in comparison with those found in unabsorbed sera.
采用间接血凝试验，检测了123匹马、142头牛、108只羊、142头成年猪和60头仔猪（3 - 4周龄）血清中抗肠杆菌科共同抗原（CA）的抗体。比较了大肠杆菌不同血清群（O149、O138、O115、O78、O9）和鼠伤寒沙门氏菌的抗CA抗体水平以及体细胞抗原（酚 - 水提取物）的抗体效价。发现效价等于或高于1:15的CA抗体在100%的受检马和牛血清中出现，而在92%的羊、80%的成年猪和60%的仔猪血清中，抗肠杆菌共同抗原的抗体效价等于或高于:7.5。在所有检测的血清中，针对大肠杆菌和鼠伤寒沙门氏菌体细胞抗原的抗体水平超过了针对肠杆菌科共同抗原的抗体水平。还检测了用CA制剂吸收血清对异源抗原抗体水平的影响。结果发现，与未吸收血清相比，吸收导致针对大肠杆菌O抗原和鼠伤寒沙门氏菌的效价在统计学上显著降低。
