Bronchopneumonia
Bronchopneumonia is a frequent lesion of the lungs in
growing pigs and is characterized by cranioventral consolidation
of the lungs. Bronchopneumonias are subclassified
as suppurative (lobular) and fibrinous (lobar) bronchopneumonias by pathologists. Mycoplasma hyopneumoniae
and/or respiratory viruses with secondary bacteria are the main causes of bronchopneumonia in the consistency will be firmer due to formation of fibrous tissue. Lungworms (Metastrongylus sp.) usually
fill small airways and will grossly resemble a mild bronchopneumonia
often affecting the edges of multiple
lung lobes, even the caudal lobes.
