摘　　要：为了解腹泻病鸡群中鸡志贺氏菌病和鸡白痢的发生情况，利用鸡鲍氏型、鸡痢疾型志贺氏菌凝集抗原和鸡白痢鸡伤寒多价抗原对河南省6个县市52家鸡场的鸡血清进行血清抗体检测。结果显示：鸡鲍氏型、痢疾型志贺氏菌血清抗体阳性率分别为31．5％和14．6％，鸡白痢为3．2％。所有县市的鸡鲍氏型志贺氏菌血清抗体阳性，4／5的县市鸡痢疾型和鸡白痢血清抗体阳性；78．8％的鸡场为鲍氏型血清抗体阳性，61．2％的鸡场为痢疾型血清抗体阳性，24．4％鸡场为鸡白痢血清抗体阳性。不同鸡群中，鸡鲍氏型血清抗体阳性率为4．4％～85．7％，鸡痢疾型为0．0～60．0％，鸡白痢为0．0～30．0％。不同品种鸡中，罗曼鸡鲍氏型、痢疾型血清抗体阳性率都较高，其次为固始鸡。不同日龄中，22～28日龄鸡的血清抗体阳性率最高，鸡鲍氏型为68．8％，鸡痢疾型为27．1％，而鸡白痢仅为6．5％。混合感染中，鸡鲍氏型和痢疾型混合感染占待检血清总数的10．1％。In the survey,serum samples from 52 chicken farms of six counties in Henan were taken and their serum antibodies were detected by means of S. boydii,S, dysenteriae and pullorosis antigen typhoid antigen, so as to further understand the incidence of Shigella disease and Salmonella in the chicken population with diarrheal disease. The results showed that the positive serum antibody was 31.5% for S. boydii,14. 6% for S. dysenteriae dysentery bacteria,3.2% for pullorosis, while the positive serum samples were found in all the six counties for chicken S. boydii,in four fifths of the counties for S. dysenteriae and dysentery pullorosis, in 78.8% of the chicken farms for S. boydii, in 61.2% of the chicken farms for S. dysenteriae and 24. 4% of the chicken farms for pullorosis disease. Among different chicken populations, the positive rate of serum antibody was 4.4% --85.7% for S. boydii,0. 0--60. 0% for S. dysenteriae and 0.0--30.0% for pullorosis. As to different varieties of chicken, Roman chicken presented higher positive rate of serum antibody for both S. boydii and S. dysenteriae, followed by Gushi chicken. Considering the ages,4- week-old chicken showed the highest serum positive rate,68. 8% for S. boydii,27.1% for chicken dysentery and 6.5% for pullorosis. The mixed infection rate of S. boydii and S. dysenteriae accounted for 10. 1% of the seized serum samples. The survey results showed that Shigellae disease was very popular in different parts of Henan province, the rate being higher than pullorosis disease.
