The endogenous stages of Sarcocystis cameli (Mason, 1910)

The endogenous stages of Sarcocystis cameli (Mason, 1910) in the small intestine of dogs are described. These stages are mainly in the posterior third of the small intestine. They were observed only in the lamina propria of the distal third of the villi. There was no schizogonic process. Micro and macrogamonts were differentiated 18 h p.i. The first zygote was observed 24 h later. Unsporulated oocysts were found 30, 36, 42, 48 h and 4 days p.i. The oocysts started sporulation on the 5th day p.i. Completely sporulated oocysts were formed 8 days p.i.
