Experimental infecting method of infectious serositis on duck
Experimental infecting method of infectious serositis on duck
摘要
The infectious serositis was transmitted to duck by Pasteurella anatipestifer through 4 paths:trachea, abdominal cavity, crop and web. The most effective path is foot web and the suitable experimental infectious dose of bacteria is 4.5×108~6×108 cfu.
