Abstract
SUMMARY A 30‐month‐old British Alpine goat had clinical and pathological findings consistent with the diagnosis of a chronic interstitial pneumonia. The goat also had lesions in the brain similar to those described for granulomatous encephalomyelitis (GE) of goats. Lesions similar to GE were reproduced experimentally in feral goats following intracerebral inoculation of a lung homogenate from the naturally occurring case. The differential diagnosis of chronic interstitial pneumonia in goats, the differentiation of GE from viral leucoencephalomyelitis, and the possible aetiological role of retroviruses in these diseases is discussed.
