“…There is a debate whether the Sarcocystis species in cattle and buffaloes are the same species (Jehle et al 2009;Chen et al 2011;Gjerde, 2013;Dubey et al 2014;Moré et al 2014). However, there is general agreement that S. fusiformis of the water buffalo is distinctive and has no morphological equivalent in cattle.…”

S U M M A R YFour valid species of Sarcocystis have been reported from the water buffalo (Bubalus bubalis): Sarcocystis fusiformis, Sarcocystis buffalonis, Sarcocystis levinei and Sarcocystis dubeyi. Here, we redescribe structure of S. fusiformis sarcocysts by scanning and transmission electron microscopy (SEM, TEM). Twenty-one macroscopic sarcocysts from oesophagus of the water buffalo in Egypt were examined by light microscopy, SEM and TEM. The sarcocyst wall was up to 9 μm thick, depending on the section and the technique. In 5 μm paraffin-embedded sections, the sarcocyst wall was indistinct, 2-5 μm thick and appeared smooth. In 1 μm plastic-embedded sections stained with toluidine blue, the sarcocyst wall was 2·5-5·2 μm thick and had branched villar protrusions (vp)-like branches of a dead tree. By SEM, the sarcocyst wall had a mesh-like structure with irregularly shaped vp that were folded over the sarcocyst wall. On each vp there were uniform papillomatous structures that were 100 nm wide. By TEM, vp were up to 6 μm long and contained filamentous tubular structures, most of which were parallel to the long axis of the projections; granules were absent from these tubules. By TEM, bradyzoites within the same cyst varied from 11·2 to 16·8 μm in length. By TEM, bradyzoites had a very long (10 μm) convoluted mitochondrion, up to 12 dense granules, but only 2 rhoptries. This redescription should help to differentiate the sarcocysts of S. fusiformis from similar sarcocysts in domestic and wild ruminants.

“…This finding should be considered by the veterinary organization due to the fact that S. cruzi has severe pathogenicity in livestock and can cause severe clinical sign, abortion, and loss of animal products, however, without any pathologic effects on the human population. Controversy, Agholi et al described that S. cruzi was detected in fecal samples of one women immunocompromised patient (HIV positive) using 18S r DNA gene amplifying and phylogenic analysis (24). The S. cruzi has worldwide distribution and is frequently reported.…”

Background: Sarcocystis species are obligatory intracellular parasites of many vertebrate hosts. Some pathogen species cause major economic loss and hygienic problems in the animal and human population, respectively. Objectives: The goal of the current study was conducted to identify Sarcocystis species in meat-producer animals and to evaluate the risk of transmission of parasites after consumption of infected meat by humans. Methods: Fifty samples of sheep and cattle muscles were collected from the abattoir. The samples were collected from the heart, tongue, diaphragm, and skeletal muscles. The PCR method was used for amplifying the 18S ribosomal RNA gene for distinguish

“…The contradictory results indicated that these serologic techniques cannot be considered as gold standards for the identification of sarcocystosis. A new report suggested a high prevalence of S. hominis in the European beef market (More et al., ). Meat specimens from different supermarkets and butcheries in Germany were evaluated by microscopic and molecular methods including conventional and multiplex real‐time PCR.…”

Foodborne parasites are a source of human parasitic infection. Zoonotic infections of humans arise from a variety of domestic and wild animals, including sheep, goats, cattle, camels, horses, pigs, boars, bears, felines, canids, amphibians, reptiles, poultry, and aquatic animals such as fishes and shrimp. Therefore, the implementation of efficient, accessible, and controllable inspection policies for livestock, fisheries, slaughterhouses, and meat processing and packaging companies is highly recommended. In addition, more attention should be paid to the education of auditors from the quality control (QC) and assurance sectors, livestock breeders, the fishery sector, and meat inspection veterinarians in developing countries with high incidence of zoonotic parasitic infections. Furthermore, both the diagnosis of zoonotic parasitic infections by inexpensive, accessible, and reliable identification methods and the organization of effective control systems with sufficient supervision of product quality are other areas to which more attention should be paid. In this review, we present some examples of successful inspection policies and recent updates on present conventional, serologic, and molecular diagnostic methods for zoonotic foodborne parasites from both human infection and animal‐derived foods.
