Bovine sarcocystosis is an economically important disease worldwide caused by the apicomplexan protozoan, Sarcocystis species. There are three main species of cattle Sarcocystis; S. cruzi (S. bovicanis), S. hirsuta (S. bovifelis) and S. hominis (S. bovihominis). The current study was conducted to identify Sarcocystis species infecting slaughtered cattle at Sharkia province, Egypt using light an...

a simple special protocol using semichon’s acetic carmine stain was applied for examination of muscles of some small mammals, naturally infected with sarcocystis spp. using this method, infected muscles fibers with sarcocystis could easily be differentiated from muscle tissues. this method can be applied for screening of infected muscles with sarcocystis cysts on large number of samples for epi...

background: the objective of the present study was to survey the presence of sarcocystis in sheep's brain in north khorasan province. methods: in general, 80 samples of sheep's brain were collected from slaugh-tered sheep in slaughterhouses of north khorasan province. tissue digestion method was used for observing bradyzoites in tissues. histopathological pro-cessing tracing sarcocystis and ens...

background: to differentiate sarcocystis macro-cyst-forming species in slaughtered sheep in babol area, mazandaran province, sequence analysis of 18s rrna gene was performed. methods: overall, 150 slaughtered sheep were examined macroscopically in slaughterhouse, babol and intra-abdominal and diaphragm muscles tissues infected with macro-cyst of sarcocystis spp. were collected in 2013. one macr...

Immunostimulating complexes (ISCOMs) are unique multimolecular structures formed by encapsulating antigens, lipids and triterpene saponins and are one of the most successful antigen delivery systems for microbial antigens. In the current study, both the route of administration and the antigen concentration of ISCOMs, containing Eimeria tenella antigens and saponins from native plants, were eval...

Sarcocystis nesbitti is an intracellular protozoan parasite found as sarcocysts within muscle fibers of intermediate hosts (monkey and baboon). The definitive host is suspected to be the snake. We report two cases from a larger cohort of 89 patients who had fever, headache, and generalized myalgia after a trip to Pangkor Island, Malaysia. Sarcocysts were detected in skeletal muscle biopsy speci...

Eimeria tenella is one of the important species as it causes caecal coccidiosis in chickens. Coccidiosis is believed to be controlled effectively using vaccines. The present study investigated the prophylactic efficacy of two locally prepared vaccines against caecal coccidiosis in broiler chicken. Broiler chicks (n = 80) were divided in four different groups A, B, C and D (n = 20 birds/group), ...

Anoplolepis tenella is a ground-nesting ant of the tropical forest zone of Central Africa, commonly associated with African root and tuber scale, Stictococcus vayssierei Richard, an emerging cassava pest. Understanding the ant’s foraging activity and diet breadth is an important step towards developing control measures against S. vayssierei. The present study was carried out in cassava fields i...

Sexual-stage glycoproteins of Eimeria are important components of the oocyst wall, a structure that ensures the efficient transmission of these and related parasites. In this study, the primary enzyme in the glycosylation pathway of Eimeria tenella, glucosamine:fructose-6-phosphate aminotransferase (EtGFAT), has been characterized as a macrogamete-specific protein. Although the transcription of...

Clinical chicken coccidiosis is mostly caused by simultaneous infection of several Eimeria species, and host immunity against Eimeria is species-specific. It is urgent to identify common immunodominant antigen of Eimeria for developing multivalent anticoccidial vaccines. In this study, sporozoite proteins of Eimeria tenella, Eimeria acervulina and Eimeria maxima were analyzed by two-dimensional...
