Valvular and mural endocarditis in a goat – a case report

Abstract

Endocarditis is the inflammation of the endocardial lining. Endocarditis may be mural when the lesions
are located on the lining of an auricle or ventricle, but it is much more frequently valvular, the lesions were
located on the valves. The current study aims at reporting an endocarditis case of a 1-year-old male Boer
goat, which had been showing clinical respiratory signs and weight loss. The treatment with enrofloxacin
and tetracycline do not have a result and the goat died. At necropsy, its kidneys were swollen, the lungs were
adhered to the costal pleura and there were nodules on the pericardial sac and heart. Histology revealed
pneumonia, hepatitis, and myocarditis with formation of abscesses, thus characterizing septicemia.
Arcanobacterium pyogenes was identified from lungs, liver and blood samples. Although A. pyogenes is
usually associated with localized infections, this report highlights the possibility of its involvement in
the septicemia due to endocarditis disease in goats.
