ABSTRACT Sarcocystis tissue cysts from the Siberian roe deer (Capreolus pygargus) were studied by light and electron microscopy. Seven out of eight roe deer were infected (85 % ) . Cysts were macroscopically visible measuring 1-4 mm in length and 0.1-0.5 mm in width. They contained typical Sarcocystis merozoites 10.8 fim in length and 2.4 /xm in width. The taxonomic relation of Sarcocystis sibi...
Water buffaloes (Bubalus bubalis) are intermediate hosts for 4 species of Sarcocystis , i.e., Sarcocystis fusiformis and Sarcocystis buffalonis with cats as definitive hosts; Sarcocystis levinei with dogs as definitive hosts; and Sarcocystis dubeyi with an unknown definitive host but thought to be zoonotic. Currently, the latter species has been identified with certainty only from Vietnam. In t...
Sarcocystis sporocysts were found in intestinal scrapings from 24 (54.5%) of 44 opossums (Didelphis virginiana). The number of sporocysts varied from a few (< 10,000) to 245 million. Sporocysts from 23 of 24 opossums were fed to captive budgerigars (Melopsittacus undulatas), and the inocula from 21 opossums were infective, indicating the presence of Sarcocystis falcatula. Sporocysts from 24 opo...
introduction: hamburger is a popular type of fast foods consumed all over the world. sarcocystis spp. is a zoonotic parasitic pathogen which endangers safety of meat and meat products. the present study describes the prevalence rate of sarcocystis spp. in hamburgers in yazd, iran using pcr-rflp. materials and methods: raw hamburger samples (100 traditional and 90 industrial) from central region...
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 spp., Neospora spp., and Toxoplasma gondii are Apicomplexa protozoa that can infect horses. This study aimed to investigate the occurrence of antibodies against Sarcocystis spp., Neospora spp., and T. gondii in horses slaughtered in southern Brazil. The presence of histological lesions, tissue cysts, and Sarcocystis spp. DNA in the hearts of these horses was also investigated. A tot...
Immunoglobulin subclass responses of wild brown rats (Rattus norvegicus) from southeastern Asia to the endemic cyst-forming coccidian Sarcocystis singaporensis were characterised. The antibody response of brown rats to wild-type parasites (high reproductive capacity) showed a Th1 profile during acute infection, namely elevated concentrations of parasite-specific IgG2b and IgG2c and absence of I...
An emaciated white-tailed sea eagle (Haliaeetus albicilla) from Western Norway was found and nursed briefly before it died. The necropsy revealed that the principal cause of death was an inflammation and occlusion of the bile ducts. A secondary finding was the presence in the intestinal mucosa of numerous sporulated Sarcocystis oocysts measuring 21.8-22.8 × 16.0-17.0 μm. The aim of this study w...
Sarcocystis neurona is an important cause of equine protozoal myeloencephalitis (EPM) in horses in the Americas. An EPM-like neurological disease also has been reported from other mammals but it is difficult to induce this disease in the laboratory. A 4-month-old male domestic cat developed neurological signs 3 days following castration. The cat was euthanized 12 days later because of paralysis...
