Fig. 2. Histology of coccidia infection in the intestine of anadromous alewives, stained with H&E, bar = 10 μm. (A,B) Spherical early developmental stages (arrowheads) within the brush border of the intestinal epithelium; (C) macrogamonts (arrowhead) (notice the notches nearly midway through the parasite, embedded within the surface of the intestinal epithelium); (D) macrogamonts with notches (arrowhead) and unsporulated elongated oocysts (arrows) within the intestinal epithelium.
