Porcine Hemophilus parahemolyticus pneumonia in Saskatchewan. I. Natural occurrence and findings.
An outbreak of fibrinous pleuropneumonia was observed in October 1971 in Saskatchewan on a farm of 900 feeder pigs. Morbidity and mortality were low. Pathologic-anatomic findings included fibrinous pleuritis, pulmonary vascular thrombosis and necrotizing fibrinous pneumonia. Hemophilus parahemolyticus was isolated from the lungs of affected animals. In addition pulmonary lesions were found which suggested an adenovirus infection. It was speculated that the viral infection possibly predisposed the pigs to the Hemophilus infection. The H. parahemolyticus isolate was sensitive to common antibiotics.
