Sporocysts of Sarcocystis were obtained from intestinal scrapings of three out of five opossums (Didelphis aurita) trapped in the southeastern region, of the State of Rio de Janeiro, Brazil. Fifteen caged budgerigars (Melopsittacus undulatus) received, orally, twenty-six sporocysts in 500 mL PBS, but only five belonging to one of the groups developed clinical signs, that consisted of anorexia, ...

BACKGROUND From the 17th to 19th January 2012, a group of 92 college students and teachers attended a retreat in a hotel located on Pangkor Island, off the west coast of Peninsular Malaysia. Following the onset of symptoms in many participants who presented to our institute, an investigation was undertaken which ultimately identified Sarcocystis nesbitti as the cause of this outbreak. METHODO...

Pathologic changes were studied in 27 interferon-gamma gene knockout mice 34-54 days after being fed graded doses of Sarcocystis neurona sporocysts derived from a naturally infected opossum. The target tissue for S. neurona infection was the central nervous system. Characteristic histopathologic changes present in all mice consisted of an inflammatory infiltrate consisting of mostly neutrophils...

fish is one of the important nutrient sources in many parts of the world. consumption of fish like other parts of the world is high in khoozestan province. the role of fish in transmission of some parasitic agents to human is investigated by many researchers. this study aims to investigate internal and external zoonosis parasites and the importance of these parasites in transferring disease in ...

Sarcocystis neurona is the most important cause of a neurologic disease of horses, equine protozoal myeloencephalitis (EPM). Cats and other carnivores can act as its intermediate hosts and horses are aberrant hosts. Little is known of the sero-epidemiology of S. neurona infections in cats. In the present study, antibodies to S. neurona were evaluated by the S. neurona agglutination test (SAT). ...

Diclazuril is a benzeneacetonitril anticoccidial that has excellent activity against the extraintestinal stages of Toxoplasma gondii and Neospora caninum. It also is highly active against intestinal coccidia of poultry. The present study examined the efficacy of diclazuril in inhibiting merozoite production of Sarcocystis neurona and Sarcocystis falcatula in bovine turbinate cell cultures. Dicl...

Sarcocystosis, in recent times has been recognized as a disease in animals and man. With the attention of scientists on this problem all over the world, work on prevalence, morphology, life cycle, transmission, pathogenesis, immunology, biochemistry and prophylaxis of this parasite has been initiated in domestic animals in India.

Objective The aim of this study was to determine the status intestinal parasitic infections in immunocompromised patients Bushehr province, southwest Iran by conventional and molecular methods. Methods A total 201 stool samples were collected from kidney transplant recipients, AIDS under chemotherapy. Samples healthy people as control group. specimens tested using various Polymerase chain react...

In 2004, three wild sea otters were diagnosed with putative Sarcocystis neurona-associated meningoencephalitis by histopathology and immunohistochemistry. Schizonts, free merozoites and tissue cysts were observed in the brains of all three infected animals. Tissue cysts walls from sea otter 1 (SO1) stained positively using anti-S. neurona polyclonal antiserum. However, positive staining does no...
