Edema of the Wattles 



Seddon ^ has recently described a disease of the wattles 

 of fowls showing two very marked symptoms, namely 

 (1) enlargement due to the presence of the inflammatory 

 fluid and later (2) distortion with the formation of hard 

 nodules of cheesy material in the wattle. He believes the 

 disease is a localized form of fowl cholera, in which the causa- 

 tive organism gains entrance to the wattles through scratches, 

 etc. Septicaemia and death occur in a certain percentage of 

 the cases. The disease usually runs a chronic course with 

 subsequent replacing of the edematous fluid by fibrous 

 tissue and results in the wattle assuming a crinkled appear- 

 ance. 



Treatment. — "Cropping" of the wattles is recommended 

 in some cases. The adoption of general sanitary measures 

 is of most service'in suppressing the disease. (See Chapter 

 11.)
