Equid herpesvirus 1 and rhodococcus equi coinfection in a foal with bronchointerstitial pneumonia.
A 2-month-old foal with septic shock and severe respiratory distress was referred to the Veterinary Teaching Hospital. Due to poor prognosis, the foal was euthanized. Histopathology showed lesions suggestive of Rhodococcus equi infection associated with a diffuse interstitial infiltrate of foamy macrophages and syncytial cells presenting large acidophilic intranuclear inclusion bodies, fibrin exudates and hyaline membranes. Bacteriological examination from lung and respiratory exudates confirmed R. equi infection, whilst immunohistochemistry and PCR yielded a positive result for Equid herpesvirus type 1 (EHV-1). Several etiologies have been proposed for bronchointerstitial pneumonia in foals, although a multifactorial origin for this lesional pattern could be possible. This work is the first one describing a combined EHV-1 and R. equi infection in a foal affected with bronchointerstitial pneumonia.
