Summary
Isospora canis, a coccidian parasite of the intestinal tract of dogs, underwent development in cultured canine and bovine cells. Daughter organisms were formed in a manner similar to endodyogeny in Toxoplasma, Besnoitia, and Sarcocystis. Pairing of organisms occurred and occasionally rosettes were observed. However, stages of schizogony as it occurs in Eimeria were not observed.
