GROUSE DISKASE 293 



^ 220. Grouse disease. In 1887 Klein described a dis- 

 ease of grouse characterized by congestion of the lungs, liver 

 and kidneys with small necrotic areas in the liver and areas of 

 redness in the intestines. The disease was found to be due to 

 a bacillus which has been found to belong to the colon group. 

 [The author has studied the bacillus of the Grouse disease a 

 cultureof which was obtained from Krahl and found it to be 

 B. coli communis.'] Migula designates it B. scotiais. 



Quail disease ( Colibacillosis tetraonidarum). In May 1907, 

 Morse {Circular No. 109, Bureau of Animal Ind^istry) described 

 a disease of quail characterized by congestion of the lungs, 

 focal necrosis of the liver, and intestinal ulceration. He found 

 the cause to be a member of the colon group of bacteria. This 

 seems to have several centers of infection in this country. 

 Several species of quail and grouse are susceptible. While 

 there are strong resemblances between this affection and the 

 grouse disease described by Klein, Morse assumes that they 

 are not identical.
