Wounds of which part of the body predispose to pycRmia ? 



In the horse, wounds about the coronary region; in calves 

 and colts, the umbilical region of the newly born; otherwise 

 bone wounds. 



What do you understand ty septicopyminia ? 



This disease is a combination of pyaemia and septicaemia. 



Describe the essential post-mortem changes of pyce,mia. 



The essential features are purulent inflammatory foci of 

 internal organs, as liver, lungs, spleen, kidneys, joints, tendon 

 sheaths, heart, muscles, etc. A purulent inflammation of the 

 synovial membrane of the joints is of special importance in 

 navel ill of the colt (polyarthritis pyaemica). Purulent 

 inflammation of the serous membranes is also seen (peri- 

 toneum, pleura, meninges), also purulent inflammation of the 

 eye (purulent choroiditis). Occasionally circumscribed hem- 

 orrhages upon the serous membranes and those pathological 

 changes peculiar to septicaemia, then septicopyaemia. At the 

 point of origin the veins are filled with a decomposing 

 thrombus (purulent thrombo-phlebitis). 



Oive the symptoms of pycemia. 



After the wound is undergoing the process of healing and 

 suppuration established, a very irregular intermittent fever, 

 sometimes ushered in with chills, is observed. Multiple sub- 

 cutaneous abscesses may appear suddenly here and there or 

 symptoms of a metastatic pneumonia or those peculiar to 

 abscesses of the liver, kidneys, brain, or serious lameness due 

 to pyaemic polyarthritis or tendovaginitis. 



What is the duration of pyczmia ? 



Longer than that of septicaemia, from several days to 

 weeks, depending on the extent and location of the metastatic
