INFECTIOUS DISEASES. 85 



Tip as the base of the tail, along the back part of the hock, under 

 the abdomen, on the sides of the neck and shoulder, on sides of 

 the chest, where the saddle rests; also around the head, face, and 

 lips. 



In acute cases, about the sixth or seventh day, these break 

 down and discharge a greenish-yellow material, which is oily and 

 sticky. In chronic cases there is no tendency to suppurate, they 

 being hard and non-painful. 



How may glanders be diagnosed? 



Principally by the ulcers, peculiar thin but oily discharge, 

 swellings of the lymphatic glands, elevation of temperature, emaci- 

 ation, and by the use of mallein. 



What disease may glanders be mistaken for? 



Nasal catarrh, pus in the guttural pouches, purpura haemor- 

 rhagica, leucocythsemia, rhino-adenitis, urticaria, lymphangitis. 



"What prognosis should be given? 



The prognosis is grave. Report all cases to the Board of Health. 



Describe the mode of treatment. 



Isolate all suspicious cases, and await development of symp- 

 toms. Give animal a full aloetic purge ; water from a separate pail ; 

 he careful about the bedding, blankets, harness, etc. Scald stalls 

 with washing soda (1J pounds to each pail of boiling water) ; then 

 use carbolic acid in water, or bichloride of mercury, and submit 

 the building periodically to chlorine or sulphurous acid gas. 



If not positive, use mallein ; inject 2| c.c. in the side- of the 

 neck, remembering to take the temperature before the injection. 

 Take temperature every two hours for at least fourteen hours, and 

 in some cases twenty-four hours. The features are, a rise of tem- 

 perature, two or more degrees, and a local swelling at the point of 

 inoculation, which is painful on pressure. Never inject mallein 

 when the temperature is above 101° F. 



Is mallein reliable? 



While mallein is not infallible, yet it is useful and should 

 be used at every opportunity in doubtful eases. 



What can be said of the blood test in glanders ? 



The blood test has its usefulness although not absolutely 

 reliable. Better results are obtained by getting a sample of blood, 

 then using mallein and comparing the results of each.
