88 PRACTICE OF EQUINE MEDICINE. 



What are the symptoms ? 



Well-marked symptoms are shown; first, a chill, followed by 

 fever, with a gradual rise of temperature from 103° to 10-1° F, 

 The chills of pygemia occur irregularly, and the temperature is 

 higher than in the sweating stage. 



The pulse is frequent, small, and intermittent. The conjunc- 

 tiva becomes yellow, there is loss of appetite, thirst, diarrhoea, the 

 animal becomes dull, the respirations are hurried and shallow. 



As death approaches, signs of delirium show themselves, the 

 pulse becomes more feeble and intermittent, and the animal passes 

 into coma and death. 



What is the differential diagnosis between septicaemia 

 and pyaemia ? 



Septiccemia shows a slight chill, while pycemia a distinct chill; 

 septiccemia only one chill at the beginning, while in pycemia the 

 chills recur. In septiccemia there are slight, if any, sweatings, where- 

 as in pywmia there are profuse sweats; in septiccemia the temperature 

 is high at the onset — 105° or 106° F., while in pycemia the temper- 

 ature gradually rises — from 102° to 104° F. Septiccemia develops 

 rapidly; pycemia, slowly. In pycemia the heart impulse is less 

 forcible than in septiccemia. Finally, thrombi and multiple ab- 

 scesses develop in pywmia and are its distinguishing objective evi- 

 dence, while they never occur in simple septiccemia. 



What is the prognosis ? 



Always unfavorable. 



What is the treatment ? 



There is the preventative treatment and the treatment of a de- 

 veloped case. The first resolves itself into cleanliness, good venti- 

 lation, sunlight, etc. 



The pywmic poison is eliminated by the intestinal tract, and 

 not by the skin or kidneys. Internal antiseptics are used; bromine, 

 carbolic and salicylic acids; the oil of- turpentine, the sulphites and 

 the hypo-sulphites of sodium, calcium, and magnesium; quinine 

 is a drug most extensively used for its antiseptic, its stimulant and 

 antipyretic powers. The patient should be supported by good nour- 

 ishment and stimulants.
