[The pathomorphology of endocardiosis in swine]

In a total of 2653 slaughter pigs of the breeds Large White, Piĕtrain and Belgic Land Race the hearts were examined grossly ad histopathologically as to the occurrence of endocardiosis of the atrioventricular valves. This lesion occurred with high incidence. Endocardiosis of the V. mitralis was diagnosed in 63.2% and endocardiosis of the V. tricuspidalis in 17.7% of pigs. In 33.6% of animals the valves proved to be normal. Possible pathogenetic factors are briefly discussed.
