sarcocyst is one of the most important protozoa belonged to apicomplexa. this parasite is prevalent among warm blooded animals throughout the world. in the present work, sarcocystis gigantea was identified by amplification of 18s rrna gene using pcr- rflp. in this regard macroscopic cysts of sarcocystis were collected from esophagus and intra costal muscles of sheep in shahriar slaughterhouse. ...
Dogs are a reservoir for Chagas disease, caused by Trypanosoma cruzi (T. cruzi), and other companion vector-borne diseases, including ehrlichiosis (Ehrlichia canis Ehrlichia ewingii), anaplasmosis (Anaplasma phagocytophilum Anaplasma platys), dirofilariasis (Dirofilaria immitis) Lyme disease (Borrelia burgdorferi). This study has two key objectives: 1) to determine seroreactivity against T. in ...
An outbreak of fever associated with myalgia and myositis occurred in 2012 among 89 of 92 college students and teachers who visited Pangkor Island, Malaysia. The Sarcocystis nesbitti 18S rRNA gene and sarcocysts were obtained from muscle tissues of 2 students. Our findings indicate emergence of S. nesbitti infections in humans in Malaysia.
Koudela B., L. Steinhauser: Evaluation of Vitality of Sarcocysts in Beef by the DAPI Fluorescence Test. Acta vet. Brno, 53,1984: 193-197. Vitality of Sarcocystis sp. cystozoites in beef was evaluated by means of the DAPI fluorescence test. Results were verified by biological assays in definitive hosts. Sarcocysts remained vital in beef kept at refrigerator temperature over a period of 20 days a...
In continuation our effort to research the chemical space of aryloxy-naphthoquinones as potential anti-Chagas agents, we synthesized nine derivatives and these compounds were evaluated in vitro against epimastigote trypomastigote forms Mexican strains Trypanosoma cruzi (T. cruzi). Most are highly active (IC50 < 1.0 µM) compared reference drug benznidazole (Bzn). Then on trypomastigotes, which i...
BACKGROUND Through 2 international traveler-focused surveillance networks (GeoSentinel and TropNet), we identified and investigated a large outbreak of acute muscular sarcocystosis (AMS), a rarely reported zoonosis caused by a protozoan parasite of the genus Sarcocystis, associated with travel to Tioman Island, Malaysia, during 2011-2012. METHODS Clinicians reporting patients with suspected A...
sarcocystis is a coccidia protozoan develops obligatory in two hosts consisting of the herbivores as an intermediate host (prey) and the carnivores as a host (predator). depend on species, the size of cysts and structure of cyst wall in intermediate hosts are different. the ultrastructure of sarcocystis cysts (sarcocysts) could be a good indication for diagnosis of the parasite species. in the ...
The prevalence of Toxoplasma gondii in free-range chickens from Campos dos Goytacazes, Rio de Janeiro State, Brazil, was examined to evaluate environmental contamination by oocysts. Antibodies against T. gondii were assayed by the modified agglutination test
The development of Sarcocystis falcatula merozoites in bovine turbinate (BT) cell cultures is described and compared with development of Sarcocystis neurona merozoites. Merozoites of S. falcatula entered BT cell cultures and increased in size until 3 days post-inoculation when the nucleus of some merozoites developed lobes. Developing schizonts present at 4 days contained a lobed nucleus or app...
The ox-cat cycle of Sarcocystis hirsuta was studied by killing 18 calves between 7 and 110 days after inoculation (DAI) with sporocysts from cats. At 7 DAI, sporozoites were found free and within leukocytes in the lumen of arteries associated with mesenteric lymph nodes and in endothelial cells of mesenteric arteries. First-generation meronts were found 7-23 DAI in arteries associated with mese...
