Figure 4. Photomicrographs of lung tissue sections from infected (A–E) and treated (F and G) squabs.

Figure 4

(A) Large schizont invading the endothelium lining of the lung tissue from squabs infected with H. columbae (black arrow, H&E, ×20), (B) small schizont (white arrow, H&E, ×20), (C) high magnification of B (white arrow, H&E, ×100), (D) schizonts in the endothelial cells of lung blood vessels (black arrow, H&E, ×40), (E) schizonts are ruptured and merozoites are disseminated in between the lung cells (black arrow, H&E, ×40), (F) schizonts were observed invading the blood vessel endothelium in squabs treated with Butalex® (H&E, ×20) and (G) schizonts were not seen in lung tissue sections of squabs treated with Eugenol (H&E, ×20).
