*Causative agent [[Rhodococcus equi|''Rhodococcus (Corynebacterium) equi'']]
*Important cause of sever, often fatal [[Lungs Inflammatory - Pathology#Granulomatous pneumonia|granulomatous]] [[Lungs Inflammatory - Pathology#Infectious causes of pneumonia|pneumonia]] in foals
*Clinical signs include depression, cough, weight loss, respiratory distress, diarrhoea, arthritis, subcutaneous abscesses
*Bacterium survives phagocytosis and multiplies
*Bacterial toxins -> caseous necrosis in lungs -> attracts inflammatory cells -> pyogranulomatous pneumonia
*Grossly:
**Multiple firm nodules, usually no encapsulation
**Partial [[Lungs Ventilation - Pathology#Atelectasis (Collapse)|atelectasis]]
*Histologically:
**Pyogranulomatous lesions
**Macrophages with ingested microorganisms in the alveoli
**Necrosis spreading through parenchyma
