Diagnosis of runting-stunting syndrome using (a) histopathological lesions showing distension of the crypts in the small intestine lined with a flattened epithelium, exfoliated cells in the crypts and inflammatory cell infiltration in the adjacent lamina propria (100×). The black arrow indicates that the crypt contains necrotic cellular debris observed at higher magnification (right, 400×). Bar indicates 25 μm. b Negative contrast electron micrograph of feces and intestine homogenates of chickens with viral enteritis
