摘要
通过流行病学及病原学的调查研究 ,从患黄痢的新生仔猪分离出 13株 O14 9大肠杆菌 ,采用兔肠结扎试验、平板免疫溶血试验对其产肠毒素性能进行了鉴定。生物学试验和血清学反应的结果表明 ,O14 9大肠菌株的被检滤液中存在热敏肠毒素 ( L T)
By the analysis of epidemiology and pathogen, 13 O 149 Escherichia coli from piglet suffered from yellow dysentery were separated. Its producing enterotoxin was tested by means of the adult rabbit ligated ileum loop assay and slide agglutination. The results of biological and serological test showed that the filtered solution of O 149 Escherichia coli contained heat sensitive enterotoxin.
