there is considerable confusion concerning the structure and synonymity of macroscopic sarcocysts in goats. in the present work, ultrastructural and molecular study on fat and thin macrocysts of sarcocystis isolated from naturally infected goats were investigated. two forms of macrocystic sarcocysts were collected from fresh oesophagus, diaphragm, skeletal muscles and heart of slaughtered goats...

Infection with Sarcocystis species is common in herbivores but is rare in bears. Histological sections of 374 black bears (Ursus americanus) from Pennsylvania were examined for sarcocysts. In total, 3 sarcocysts were found in 3 bears, with 1 sarcocyst per section. Sarcocysts from 2 bears were considered a new species, Sarcocystis ursusi. Sarcocysts of S. ursusi n. sp. were microscopic and conta...

Two structurally distinct types (A, B) of microscopic sarcocysts were found in muscles of 4 of 5 feral skunks. Type A sarcocysts had sarcocyst walls of up to 6 microm thick. The villar protrusions (Vp) on the sarcocyst wall were up to 5 microm long. The Vp were constricted at the base, expanded in the middle, and had a blunt tip. Numerous microtubules were present in the Vp and in the granular ...

The number of Sarcocystis species that infect sea otters (Enhydra lutris) is unknown. Sea otter tissues were recently shown to harbor sarcocysts of S. neurona and of unidentified species of Sarcocystis. Whereas sarcocysts of S. neurona have walls 1-3 microm thick with type 9 villar protrusions, ultrastructure of a distinct thin-walled sarcocyst (0.5-0.7 microm thick) lacking villar protrusions,...

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...

Sarcocystis infections have been reported from the African buffalo ( Syncerus caffer ), but the species have not been named. Here we propose a new name Sarcocystis cafferi from the African buffalo. Histological examination of heart (92), skeletal muscle (36), and tongue (2) sections from 94 buffalos from the Greater Kruger National Park, South Africa, and a review of the literature revealed onl...

Background: Fatty acid mobilization and inflammatory response of adipose tissues vary in various depots, hence the response of fat-tailed and thin-tailed sheep breeds to different energy balances was hypothesized to be different due to differences in proportion and metabolism of various adipose depots in these breeds which may affect whole body insulin sensitivity. Objective: Current study aime...

the parasites of genus sarcocystis are among the most commonly found parasites in domestic ruminants and some species of sarcocystis can generate important economic loss when causing clinical and subclinical diseases. sarcocystis hominis, one of the three species of sarcocystis that cause muscular cysts in cattle, can infect the human intestinal tract. there is high infection rate of sarcocyst ...
