Fryer individually day age can be affected, easy sensibility of Dan Youchu is highest, acute of Chang Chengqun happening breaks out the gender is passed, dead amount is large, mortality is % of 5 % —50 commonly, and it is only into chicken send out quality.
Clinical symptom

This ill general component is acute model (weigh breath again model or defeat blood group) and chronic model. Depressed of ill chicken spirit, be addicted to sleeps, appetite decreases or abandon absolutely.

Individual birds appears only the nerve symptom such as paralytic, convulsions, cervical twist. Acute often be after occurrence symptom 2 - 3 days of death, 1 - the chickling Chang Daqun of 4 week age comes on, mortality is 5 % - 50 % , show chronic course more into chicken, mortality is not tall.
Pathology changes

Pathological changes basically sees at lung and gasbag, lung sees bacterium colony of mould having music and Su Li come greatly gram pieplant white or hoar cheese appearance are necrotic and nodal, its character is stronger, tangent plane has layer shape structure it is thus clear that, the center is caseous appearance necrotic organization. Defeat blood type pathological changes badly, the yellow that gasbag has homocentric circle state it is thus clear that is necrotic kitchen, expand even the organ such as liver, heart, kidney and milt.
