Sarcocystosis is regarded as one of the most important protozoal infections buffaloes. This study was conducted to determine prevalence Sarcocystis spp. in water buffaloes (Bubalus bubalis) slaughterhouses Sharkia province, Egypt. In addition, effect age and sex on infection rates reported. Therefore, isolates were identified morphologically using macroscopic, microscopic histopathological exam...

A Hawaiian monk seal (Monachus schauinslandi) died in captivity at the National Marine Fisheries Service, Kewalo Basin Facility in Honolulu, Hawaii. The animal was icteric, and the liver was friable. Microscopic lesions were detected in the colon and liver. Colonic lesions included multifocal, necrohemorrhagic colitis associated with gram-negative bacilli. The liver lesions included random hepa...

The different genera currently classified into the family Sarcocystidae include parasites which are of significant medical, veterinary and economic importance. The genus Sarcocystis is the largest within the family Sarcocystidae and consists of species which infect a broad range of animals including mammals, birds and reptiles. Frenkelia, another genus within this family, consists of parasites ...

A study was designed to develop an experimental model to produce Sarcocystis neurona encephalitis in horses. Sarcocystis neurona, isolated from the spinal cord of an ataxic horse, was placed in continuous culture using bovine turbinate cells, and the cultured S. neurona merozoites were used to infect lymphocytes. A horse that was subsequently experimentally infected with 100,000 of the S. neuro...

Seven members of a 15-man U.S. military team that had operated in rural Malaysia developed an acute illness consisting of fever, myalgias, bronchospasm, fleeting pruritic rashes, transient lymphadenopathy, and subcutaneous nodules associated with eosinophilia, elevated erythrocyte sedimentation rate, and elevated levels of muscle creatinine kinase. Sarcocysts of an unidentified Sarcocystis spec...

In January 1998 and 1999, two mass strandings of dolphins occurred in Wellfleet, Massachusetts. The strandings were composed of 97 and 53 animals, respectively. Tissues from 35 Atlantic white-sided dolphins (Lagenorhynchus acutus) from the 1998 stranding and 52 from the 1999 stranding were examined histologically. In the 1998 stranding, unidentified protozoal tissue cysts were seen in skeletal ...

Sarcocystis neurona are apicomplexan parasites that can cause mortality in domestic and wild animals. Twelve antigen types are described for S. neurona, however just two phenotypes (SnSAG 1 and SnSAG 5) represent the majority of those that are associated with disease. A novel S. falcatula gene, antigenically indistinct from SnSAG 6, was cloned into an expression vector and the recombinant prote...

An unidentified isolate of a Sarcocystis falcatula-like parasite was obtained from the lungs of budgerigars (Melopsittacus undulatus) fed sporocysts from a naturally-infected South American opossum, Didelphis albiventris from Brazil. Four captive budgerigars fed sporocysts from the opossum intestine died of acute sarcocystosis 8, 10, and 12 days after oral inoculation (DAI); one budgerigar was ...
