SYMPTOMS OF THE DISEASE 
The symptoms observed in this outbreak among the young birds are as 
follows: 
In the initial stages, the symptoms may be overlooked if the birds are in 
any way alarmed. Unalarmed, the birds may show signs of dozing. When 
awakened, especially if startled to a small degree, the bird does not present 
a normal facial appearance, and the action of the head is of a nervous type. 
The bird on arising will show symptoms of weakness of gait. These symp¬ 
toms are progressive until the bird becomes prostrate. In the advanced 
stages, the bird when at ease for a moment will sit with the head and tail 
down (Figure 16), and when it moves shows signs of exhaustion. Loss of

flesh may be rapid, according to the severity of the disease. The bird may 
become partially comatosed, and if sitting, the head may fall forward till 
the beak touches the ground, or in a complete state of coma, when the 
bird lies on its side with the head curved under its breast. At this stage 
there is complete loss of the use of the muscles of the neck, and the bird is 
unable to walk. The bird may die without a struggle, or it may die in 
spasms. There is soon observed an unkempt appearance of the feathers, and 
a sulphui colored liquid discharge from the bowel. The face, comb, and 
wattles usually are highly anemic. 
GROSS PATHOLOGY 
The carcass is usually emaciated, the degree of emaciation depending on 
the seveiity and course of the disease. The face, comb, and wattles are 
anemic, edema may be present in the thorax, or may extend over the liver. 
The pei icai deal fluid may be increased in quantity. More rarely there may 
be abdominal hemorrhage with suggilations of the mucous membrane lining 
the intestines.
