GLOSSANTHRAX OR BLAIN. 



This disease, as described by Youatt in his work on cattle, 

 and observed by many veterinarians in former years, does 

 not prevail to any extent now-a-days. It is a form of anthrax, 

 characterized by the development of malignant carbuncle in 

 the mouth, and especially on the tongue. It is the Zungen- 

 krebs of old German authors, and the Zungen-Karbunkel of 

 others. The disease has been seen by Morel in France 

 amongst sheep, though it is a form of anthrax almost entirely 

 confined to cattle; and when the virulent poison developed 

 in the course of the disease enters the system of other animals, 

 it produces a putrid fever, diarrhoea, &c., and not necessarily 

 the carbuncle in the tongue. 



Glossanthrax appears without premonitory signs. Rychner 

 says that cases may be looked for in districts where anthrax 

 prevails when the foot-and-mouth disease is raging. White 

 pustules occur on the tongue, cheeks, lips, palate, or near the 

 frsenum linguse. The pustules vary in size from a bean to a 

 hen's egg; usually there is one large pustule. Whether there 

 be one or more, their malignant character is discovered by 

 observing a rapid change in their colour from white to red 

 and purplish black. There is much constitutional disturbance, 

 and as the disease advances there are the signs of stupor, 

 languor, &c., peculiar to putrid fever, or blood diseases. 

 Sometimes slight fever precedes the local eruption, but usually 

 succeeds it. In about 12 or 14 hours, the affected part 

 begins to slough off, and the whole tongue sometimes drops 

 piecemeal out of the mouth. Death occurs in from 24 to 30 

 hours.
