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.
猪圆环病毒 2 型（PCV2）感染分布于全球，PCV2 相关疾病（PCVAD）被认为是对全球养猪业最具经济相关性的疾病之一。PCV2 已知在猪呼吸道疾病综合征中起因果作用，通常与大量其他生物制剂密切相关。本文描述了一例由细颈囊尾蚴引起的致命性寄生性支气管肺炎的病例，该病例发生在感染 PCV2 的猪中。细颈囊尾蚴病仍可能是户外畜群的主要关注点。我们最近的经验表明，并发的 PCVAD 状况可能引发细颈囊尾蚴病，而细颈囊尾蚴病随后可能导致严重的、有时甚至致命的肺部疾病。
