Fig. 1. Pullorum disease. Perivascular proliferative inflammatory focus in the liver, consisting mainly of histiocytes and single epitheloid cells (arrow). H/E, Bar = 25 µm.
Fig. 2. Fowl typhoid. Areactive fibrinoid necrosis (N) in the liver. H/E, Bar = 40 µm.
Fig. 3. Fowl typhoid. Periarteriolar fibrinoid necrosis (N) in the spleen. Marked cell reaction in the periphery of the necrotic foci involving lymphocytes, histiocytes and single granulocytes. H/E, Bar = 50 µm.
Fig. 4. Fowl typhoid, hen. Mononuclear inflammatory cell proliferate in the myocardium (arrow). H/E, Bar = 30 µm.
