Prevalence of species of Sarcocystis in muscle of 36 caribou, Rangifer tarandus terraenorae, shot in Newfoundland, Canada, was 53%. A greater percentage of infected animals were obtained from the central part of the island. The highest concentration of microscopic sarcocysts, 1/mm2 of tissue, was observed in a 5-year old animal. Although widely distributed throughout the body, cysts were more p...

Partial changes of color (greenish to brownish) were found in prime marbled beef of Japanese black cattle. The disseminated lesions of the skeletal muscles were histopathologically examined in relation to Sarcocystis infection. The lesions in the muscles showed granulomas with inflammatory cell infiltration. The sarcocysts had a distinct wall, which was radically striated by palisading villar p...

Sarcocystis sporocysts from the intestines of 2 opossums (Didelphis albiventris) from Argentina were fed to gamma-interferon knockout (KO) and nude mice. Protozoal schizonts were seen in brain, liver, spleen, and adrenal glands of mice examined 33-64 days after feeding sporocysts. Sarcocysts were seen in skeletal muscles of KO mice 34-71 days after feeding sporocysts. Schizonts and sarcocysts w...

Alternanthera tenella Colla extracts are used in Brazilian traditional folk medicine to treat a variety of infectious diseases as well as inflammation and fever. In this work, the immunomodulatory, anti-inflammatory and potential toxic effects of cold (CAE) and hot (HAE) aqueous extracts of A. tenella were investigated in vivo. In addition, we analyzed the phytochemical properties of both extra...

The major histocompatibility (B) complex influence on resistance, susceptibility, and immunity to Eimeria tenella was examined in UCD B complex congenic chicken lines. In Experiment 1, 6-wk-old chicks from 12 UCD congenic lines were weighed and assigned to either challenge or control groups. The challenge group received a dose of 10,000 E. tenella oocysts. Response to challenge was evaluated by...

Excellent book is always being the best friend for spending little time in your office, night time, bus, and everywhere. It will be a good way to just look, open, and read the book while in that time. As known, experience and skill don't always come with the much money to acquire them. Reading this book with the PDF adolescents in psychiatric residential treatment and 5 years later acta psychia...

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. ...

Coccidiosis in chickens is caused by 7 species of Eimeria. Even though coccidiosis is a complex disease that can be caused by any combination of these species, most of the molecular research concerning chicken coccidiosis has been limited to Eimeria tenella. The present study describes the first large-scale analysis of expressed sequence tags (ESTs) generated primarily from second-stage merozoi...
