In general
- Some viruses are thought to induce modifications of the pulmonary defences by:
- Damaging the upper respiratory tract, thereby facilitating bacterial attachment and colonisation, with reduced mucociliary clearance
- Decreasing surfactant levels by destroying Type 2 pneumonocytes
- Impairing the phagocytic ability of alveolar macrophages

Porcine Reproductive and Respiratory Syndrome
Postweaning multisystemic wasting syndrome (PMWS)
- Caused by a porcine circovirus alone or in combination with porcine parvovirus
- May cause mild interstitial pneumonia, failure of lungs to collpse on opening the thoracic cavity
- Microscopically: thickening of alveolar wall due to type 2 pneumocyte hyperplasia
