Symptoms in Cattle 



According to Tokishige, also the following are the 

 symptoms found in Japan amongst cattle affected with 

 a disease which he recognized as being caused by the 

 saccharomyces, in 1890, viz. : — 



The nodules are distributed all over the surface 

 of the body without any particular arrangement, 

 contrary to those seen amongst solipeds, in which the 

 nodules are in beaded chains ; they form clearly-defined, 

 indolent lumps, varying from the size of a hazel nut to 

 that of a walnut. The development is much slower 

 than in the horse, and the nodules take three times as 

 long to come to a head and burst. 



In referring to the disease in cattle, care should be 

 taken not to confound it with a disease found amongst 

 cattle in Gaudaloupe, known under the name of farcin 

 du boeuf, and due to a bacillus discovered by Nocard, 

 and which Metschnikoff describes as a streptothrix. 

 This disease is only transmissible to cattle, sheep, and 

 guinea-pigs, but does not affect horses or donkeys. 



PosT-MoRTEM Lesions 

 The corded and beaded lymphatics observed are 

 simply inflamed lymphatic vessels, with their thickened 

 walls, their internal membrane is congested, and the 

 ducts are blocked with thick-clotted lymph mixed with 

 pus, which is followed by the formation of the abscesses 

 (pustules) and granulating sores. The affected parts are 

 found to be indurated and thickened by the formation of 

 fibrous tissue resulting from the chronic inflammation 

 set up by the disease. As already stated, the ulcera- 

 tions on the mucous membrane are characterized by 

 their round, well-defined, raised borders and dug-out 

 appearance. They are at first isolated, but later become 

 • confluent, and have as a rule a great tendency to granu-
