Pigeon squabs, aged 5-26 day-old, showed clinical signs of dullness, anorexia, indigestion, retention of feed in crop, progressive emaciation then died. The morbidity rate and mortality rate were 7.14 percent (50/700). The adult pigeons did not show any signs of disease. From pathological finding, pharyngitis, esophagitis were found with diphtheritic membrane covering necrotic ulcers on the mucosa of pharynx, esophagus and crop. From histopathological findings, esophagitis with epithelial hyperplasia and sloughed, lamina propria mucosa edema with lymphoid cells infiltration were found in duodenum and jejunum. The intranuclear inclusion body, Cowdry type A, was found in epithelial mucosa of esophagus, enterocyte of jejumum and lymphoid cells in spleen. FA test to duck virus enteritis and inoculation to ducklings showed negative results. Electron microscopic study revealed electron dense core sized 146-167 nm., which was identified as herpesvirus.
