Cocciodiosis, probably due to Eimeria sp., was found in the gallbladder of a goat. Meronts, gamonts, and oocysts were found in the epithelium of villous and submucosal glands. Meronts were 11.7 x 7.7 /^m and contained 3-20 merozoites; merozoites were 8-12 ^im long and 1.5-2.3 /urn wide. Macrogamonts and unsporulated oocysts were 9.6 x 8.7 /um and 11.6 x 9.5 ^m, respectively. There was generaliz...

Introduction: Sarcocystis species are one of the most important meat borne parasites. Sarcocystosis causes several symptoms in human as well as numerous diseases with high economic impact in livestock. In current paper at first results of a pilot study for determination of disease agent in lamb of Yazd province central Iran is presented. Then status of parasite in red meat products in study reg...

Background: Sarcocystosis in South American camelids (SAC) is an important parasitic disease which results in economical loss due to carcass condemnation. Meat products from camelids are significant source of animal protein in several American countries. Sarcocystis spp. producing macroscopical cysts in these animals have been nominated as S. aucheniae, S. tilopodi, and S. guanicoecanis. The ai...

Background: Sarcocystosis is one of the most distributed parasitic diseases over the world, caused by Sarcocystis spp. In this study, we assessed the effect of electron beam irradiation on the viability of Sarcocystis spp. in beef.  Methods: Experimental beef groups were irradiated by four different electron beam doses of 1, 2, 3, and 4 kGy, at intervals of 0 and 24 h after irradiation, then t...

Background: Sarcocystosis is one of the most widespread parasitic diseases in cattle caused by three main species of Sarcocystis genus. The major aim of this study was to determine the prevalence of Sarcocystis spp. in meat produced in Yazd, central Iran with special reference to species identification, using Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP).  ...

There is considerable confusion concerning Sarcocystis species in camels. Five species: Sarcocystis cameli, Sarcocystis ippeni, Sarcocystis camelicanis, Sarcocystis camelocanis and Sarcocystis miescheri were named with inadequate descriptions and no type specimens. Here, we review literature on sarcocystosis in camels worldwide and redescribe structure of S. cameli and S. ippeni sarcocysts by l...

From a total of 32 717 cattle slaughtered, 183 whole carcass condemnations were attributable to 9 diseases and conditions, namely, tuberculosis (TB), cysticercosis, emaciation, generalised lymphadenitis, jaundice, abscesses, moribund, sarcosporidiosis and odour. Bovine TB was the most important cause of condemnations (152/183, 83.1%). Bovine cysticercosis and sarcosporidiosis accounted for 5/18...

Serological methods for the diagnosis of toxo-plasmosis have received considerable attention since the first authentic report of a fatal infection in a human infant (Wolf, Cowen, and Paige, 1939). The complement fixation reaction (Warren and Sabin, 1942) and the dye test (Sabin and Feldman, 1948) are now recognized as the two best methods of detecting the disease. Serological studies in sarcosp...
