SUPPURATIVE HEPATITIS. HEPATIC ABSCESS. 



Causes in horse : pyaemia, omphalitis, thrombosis,, infection, biliary 

 calculi, concretions or parasites, foreign bodies, hot, damp climates, 

 strangles, brustseuche, glanders, endocarditis. I/esions in horse : from 

 parasites and mechanical irritants, pea-like or hazel-nut ; embolic abscess, 

 pin head to hen's egg ;, infection from strangles, foreign bodies, etc. , may 

 be of large size, and burst into adjacent organs, the peritoneum or exter- 

 nally. Symptoms in horse : of pre-existent malady, remitting fever, suc- 

 cessive chilis, intermittent icterus, hypochondriac tenderness. Spontaneous 

 recovery, aspiration, opening, antiseptics locally and generally. Lesions in 

 ruminants ; secondary multiple abscesses, bean-like or (with foreign body) 

 very large, may extend into adjacent parts. Symptoms in cattle : fever, 

 chills, jaundice, tympany, diarrhoea, dysentery, wasting, tender right hypo- 

 chondrium. Treatment : as in horse. Causes in dog : foreign bodies, 

 tumors, infections, blows, traumas. Lesions : traumatic abscesses, single, 

 large, infectious abscesses multiple, small. Former foetid. Symptoms in 

 dog : hepatic congestion or colic, then chills, prostration, irritability, ten- 

 derness of right hypochondrium, nausea, vomiting. Treatment in dog : 

 antiseptic aspiration, laparatomy. 



Causes in the Horse. Hepatic abscess arises from a great 

 many primary morbid conditions. As a secondary abscess it is 

 seen in the different forms of pyaemia arid especially in suppura- 

 tive omphalitis in young animals. It may start in thrombosis 

 determined by clots or septic matters carried from a distance 

 through the portal vein or hepatic artery, in biliary calculi or 

 concretions, in parasites introduced from the duodenum, in barbs 

 or husks of the cereals that have penetrated through the biliary 

 ducts, or in bacteria or their toxins which have been carried from 

 the bowels, spleen or pancreas. The government veterinarians 

 have found it a comparatively common lesion in the hot damp 

 climate of Hindoostan, and a similar frequency has been noticed 

 in west Africa. Among general affections it is liable to occur in 

 strangles, contagious pneumonia, glanders, endocarditis of the 

 left heart and phlebitis with the formation of thrombi in the
