Purulent pericarditis indicates the presence of pyogenic organisms e.g. [[:Category:Staphylococcus species|''Staphylococcal'' species]]. It is most commonly seen in cattle as a result of traumatic penetration of the pericardial sac with a sharp metallic object or ''wire''.  This is [[Traumatic_Reticulitis|traumatic reticulo-peritonitis]] causing [[Traumatic Pericarditis|traumatic pericarditis]]. It is most commonly due to the indiscriminate feeding of cattle. Objects become lodged in the rumen and are then forced by ruminal contractions into the reticulum and cranially into the diaphragm and pericardium. They may also penetrate the liver. Large amount of purulent material, up to 4 litres, can accumulate in the pericardium, causing severe constriction of the ventricles.
