CIRCULATORY DISTURBANCES

  

 

1) Renal Hemorrhages

 

   ∙ 

common; petechial or ecchymotic (if renal capsule is not removed, hemorrhage can be easily 

overlooked); 

   ∙ 

glomeruli are often preferentially involved, giving a speckled appearance to the kidney on surface 

and on section; 

   ∙ 

e.g. 

 septicemia: “turkey egg" kidneys in pigs with salmonellosis, erysipelas, etc.; 

 viral infections:  canine herpesvirus, hog cholera; 

 

 

 coagulopathies / disseminated intravascular coagulation (DIC); 

   ∙ 

if bacteremia / septicemia is suspected, tissues such as lung, kidney and liver should be sent for 

bacteriology.
