STRANGLES. 



Synonyms. — Febris pyrogenica ; morbus glandulosus ; 

 gourme (French) ; colt-ill ; druse, kropf (German). 



Definition. — A specific febrile disorder, in which there 

 are purulent accumulations in the connective-tissue of the 

 submaxillary region and in the neighbouring glands, accom- 

 panied by inflammation of the upper air-passages. 



Origin of the name Strangles. — This disease received 

 its name from the great difficulty of respiration, accompanied 

 by a trumpet-like sound, more marked in inspiration, these 

 early signs resembling those of strangulation. 



Geographical Distribution. — AYidely spread over the 

 whole world, but said to be absent in Africa and Arabia. 



Varieties. — Benign and malignant strangles. 



Prognosis. — The benign form seldom extends beyond a 

 period of fourteen days, and nearly always terminates 

 favourably. Malignant strangles may be of one or two 

 months' duration, and the animal may die of various com- 

 plications, viz., pysemia, asphyxia, or peritonitis. 



Contagium. — Strangles is, no doubt, both contagious and 

 infectious, and may assume an epidemic form. 



Etiology. — This disease is more prevalent in autumn and 

 summer than in spring. Young horses, between the age of 

 two and three, are especially liable to become affected, though 

 it is not uncommon for aged horses to take it. The disease 

 takes on the malignant form when the animals have been 

 subjected to mal-hygienic conditions and to other debilitating 

 influences.
