| − | *Lesions resemble [[Respiratory Parasitic Infections - Pathology#Dictyocaulus filaria|''Dictyocaulus filaria'']] but are fewer in numbers, lobular and at periphery of caudal lobes, they are very similar to [[Respiratory Parasitic Infections - Pathology#Muellerius capillaris|''Muellerius capillaris'']] lesions

| |
| − | **Multifocal [[Lungs Inflammatory - Pathology#Interstitial pneumonia|interstitial]] [[Lungs Inflammatory - Pathology#Infectious causes of pneumonia|pneumonia]] grossly evident as firm "lead-shot" nodules throughout the parenchyma, often with enveloping granulomatous response
| |
| − | **Early stages are reddish in colour, turning later to greyish green, may calcify
| |
| − | **Mostly in dorsal region of caudal lung lobes
| |
| − | *Histologically:
| |
| − | **Damaged alveolar septa with mild fibrous thickening and lymphocytic infiltrate

| − | **In more developed host resistance, foci of eosinophils around larvae, hyperplastic epithelium, macrophages, giant cells
| |
| − | **May be some calcification

| |
| − | *May cause severe pneumonia in calves housed where infected pigs were housed previously
| |
| − | *Cause diffuse [[Lungs Inflammatory - Pathology#Interstitial pneumonia|interstitial pneumonia]] with haemorrhage, [[Lungs Ventilation - Pathology#Atelectasis (Collapse)|atelectasis]], [[Lungs Circulatory - Pathology#Pulmonary oedema|interlobular oedema]] and [[Lungs Ventilation - Pathology#Emphysema|emphysema]]
