A) within neurons of proventricular intramural vegetative ganglia with inflammatory infiltration, bar = 25 µm; B) within nerve fibers of the myenteric plexus of gizzard, bar = 25 µm; C) within smooth muscle fibers of the proventricular wall, bar = 50 µm; D) within a modified muscle fiber of the conductive system of the heart, bar = 50 µm; E) within myocardiocytes, bar = 25 µm.
