leucorrhoea, eruptions on the mucosa of the vagina, erections of the 

 clitoris, straining, inguinal swellings, sterility or abortion, lameness, 

 trembling, anemia and emaciation, ending the same as in the stallion. 



What is the treatment for dourine? 



Local antiseptics; arsenical preparations internally. "Sal- 

 varsan" is being strongly advocated. Prevention: isolate, prevent 

 copulation, castrate and use sanitary police measures. 



What is infectious abortion ? 



Infectious abortion is the premature expulsion of the foetus, seen 

 in cows, less commonly in mares, due to an infectious catarrh of 

 the uterus transmitted by copulation or contagion. Infectious abor- 

 tion of cows is due to the bacillus of Bang. Etiology is not fully 

 determined in the mare. 



Granular venereal disease, which is quite prevalent, is frequently 

 associated with abortion in cows. 



Name some of the more recent methods of diagnosing infectious abor- 

 tion. 

 Agglutination test, complement fixation test and the allergic test 

 with "abortin." The allergic test is not reliable at present.

What is " swamp fever " or infectious anaemia? 



Infectious anaemia is a specific infectious disease of the horse 

 which is manifested sometimes as an acute, at other times as a 

 chronic, septicaemia, and causes a destruction of great numbers of 

 red blood-corpuscles. It is caused by an ultramicroscopic micro- 

 organism. 



Define anaemia, leukaemia and haemophilia. 



Anaemia is a condition in which the blood is deficient either in 

 quantity (oligemia) or in quality (oligocythaemia). 



Leiikaemia is a fatal disease in which there is a marked increase 

 in the number of leucocytes in the blood, together with an enlarge- 

 ment and proliferation of the lymphoid tissue of the spleen, 

 lymphatic glands and bone-marrow. 



Haemophilia is a condition marked by a strong and abnormal 

 tendency to Weeding, or hemorrhage, and is usually hereditary. 



State the causes of anaemia and give treatment. 



Causes: Inanition, unsanitary surroundings, overwork, poisons, 

 lack of exercise, hemorrhage, persistent diarrhcea, long-lasting sup- 

 puration, copious transudation, chronic diseases, parasites, infec- 

 tion, etc.
