Clostridia are uncommon causes of pleuropneumonia in wildlife In human and domestic animals, different Clostridia species may affect pulmonary structures causing a necrotizing and hemorrhagic pneumonia with involvement of the pleura. In livestock, most cases are associated with sudden changes of diet, iatrogenic lesionscaused by invasive procedures such as thoracentesis or thoracotomy, or traumatic percutaneous introduction of the microorganism. The clinical course of pleuropneumonia by clostridia infections may be very variable, although usually are associated with hyperacute or acute course and high mortality. The present report describes an uncommon case of necrotizing pneumonia and sepsis caused by Clostridium perfringens in Cervus timorensis with hyperacute fatal course, highlighting clinical, epidemiological, microbiological, and histopathological aspects.t
