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? 



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

 septicaemia only one chill at the beginning, while in pyaemia the 

 chills recur. In septicaemia there are slight, if any, sweatings, 

 whereas in pyaemia there are profuse sweats; in septicaemia the 

 temperature is high at the onset — 105° or 106° F., while in pyaemia 

 the temperature gradually rises — from 102° to 104° F. Septicaemia 

 develops rapidly; pyaemia, slowly. In pycemia the heart impulse 

 is less forcible than in septicaemia. Finally, thrombi and multiple 

 abscesses develop in pyaemia and are its distinguishing objective 

 evidence, while they never occur in simple septicaemia. 



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 pyaemic 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 

 nourishment and stimulants.
