Histopathology and Cytology of
Poultry Diseases
By Ivan Dinev, DVM, PhD


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.

Fig. 3. Perivascular inflammatory cell
proliferate in the pancreas (arrow).
H/E, Bar = 50 µm.
