Abstract: | Porcine circovirus type 2 (PCV2) infection is distributed worldwide and PCV2-associated disease (PCVAD) is considered among the most economically relevant ones to the global swine industry. PCV2 is known to play a causal role in the porcine respiratory disease complex, usually in close association with a large plethora of other biologic agents. We describe herein a case of fatal parasitic bronchopneumonia by Metastrongylus elongatus in a PCV2-infected pig. Metastrongylosis may still represent a major concern for outdoor herds. Our recent experience suggests that a concurrent PCVAD condition may trigger metastrongylosis, which may subsequently result, at its turn, in severe, sometimes fatal, pulmonary disease. |
