                                    Citation: Hilali, M., El-Seify, A., Zayed, A., El-Morsey, Dubey, J.P. 2011. Sarcocystis dubeyi (Huong and Uggla, 1999) infection in water buffaloes (Bubalus bubalis) from Egypt. Journal of Parasitology. 97:527-528.Interpretive Summary: Species of the genus Sarcocystis are single celled parasites.  They can cause acute or chronic illness. Some species of the genus are zoonotic. Sarcocystis dubeyi  of water buffaloes is considered zoonotic. Scientist report the presence of this parasite in water buffaloes from the Egypt for the first time. The results will be of interest to biologists, parasitologists, and veterinarians.
                                Technical Abstract: Water buffaloes (Bubalus bubalis) are intermediate hosts for 4 species of Sarcocystis, i.e., S. fusiformis and S. buffalonis with cats as definitive hosts, S. levinei with dogs as definitive hosts, and S. dubeyi with an unknown definitive host, but thought to be zoonotic. Currently, the latter species has been identified with certainty only from Vietnam. In the present study, sarcocysts of S.dubeyi are reported in 11 (30%) of 35 Egyptian water buffaloes from which the esophageal muscles were examined histologically.  Sarcocysts were microscopic, measuring 180 – 250 x 70 – 110 μm in size. Ultrastructurally, the sarcocyst wall was 3.5– 6.5 μm thick and had palisade-like villar protrusions, which give it the striated appearance.  The villar protrusions contained microtubules that were distributed along the whole villus. This is the first report of S. dubeyi from water buffaloes in Egypt.
