[Method]The dead cases of calf diarrhea were collected from a large-scale beef cattle farm,and the isolated pathogen was conducted molecular identification,serological identification,drug sensitivity test,and mice pathogenicity test,respectively. Targeted therapy was undertaken thereafter to herds. [Result] One strain of bovine pathogenic E. coli,serotype O101 with strong multidrug resistance and high pathogenicity to mice,was successfully isolated. It was used to develop sensitive drug for timely treating follow-up diarrhea calves,and successfully controlled calf diarrhea in the farm. [Conclusion]The results provide a basis for effective prevention and control of bovine colibacillosis.展开更多
