Intestinal cryptosporidiosis in turkeys in Iran.
Naturally occurring cryptosporidiosis is reported in turkey poults suffering from diarrhoea and unthriftness in Iran. Histological and ultrastructural studies revealed high number of Cryptosporidium developmental stages mainly located in the mid and terminal portions of small intestine of the poults. Other portions of the intestinal tract were less frequently infected. Oocyst shedding was detected only in 29% of the histologically positive birds. Based on host species, clinical signs, pathology and tissue location of the parasites, Cryptosporidium meleagridis was most likely responsible for these infections. This parasite was also reported recently in a child with diarrhoea in Iran.
