    VIRAL ENTERITIS COMPLEX (RUNTING STUNTING SYNDROME)

    Fig. 1. Diffuse inflammatory cell proliferate in small intestinal mucous coat. Chickens at the age of 5 - 12 days are affected. Etiologically, reoviruses, astroviruses and rotaviruses, individually or collectively, are involved. The possible vector of infection are the larvae of the lesser mealworm beetle Alphitobius diaperinus. H/E, Bar = 100 µm.

    Fig. 2. Appearance of cystic crypts (arrows) in duodenal mucosa. The primary cause is possibly a retention resulting from the compression of the inflammatory proliferate in the mucous coat. H/E, Bar = 35 µm.
