| [clinical, parasitological and serological investigations in sarcosporidiosis (sarcocystis suihominis) of man (author's transl)]. | eight medical students ate for a test raw meat from a pig experimentally infected with sporocysts of sarcocystis suihominis. the meat had been officially controlled before and was found free of trichinella and qualified for consumption. 6 to 24 hours after the meal all persons suffered from acute clinical symptoms, above all diarrhoea and vomiting, coldness and sweating which decreased, however, within 12 to 24 hours. clinical-chemical investigations made during this time suggested an acute infe ... | 1978 | 98426 |
| [light and electron microscopic studies to the development of muscle cysts of sarcocystis suicanis in experimentally infected pigs (author's transl)]. | six young pigs were experimentally infected with 100000 sporocysts of sarcocystis suicanis and killed on the 32nd, 47th, 55th, 64th, 81th and 90th day p.i. the ultrastructure of sarcocysts in the muscle cells was studied. light microscopical preliminary examination on the 32nd day p.i. showed cysts which lay in muscle fibres and were surrounded by a fine membran. on the 55th day p.i. the cyst wall showed radial light and dark stripes of 2.6 micrometer thickness, which reached a thickness of 3.2 ... | 1978 | 103340 |
| electron microscopical study on gamogony of sarcocystis suihominis in human tissue cultures. | sexual stages and oocysts of sarcocystis suihominis were developed in human tissue cultures and studied with the electron microscope. this development was extremely rapid, being completed about 18--22 h post infection and there were no preceding schizogonic processes, thus confirming the earlier observations that schizogony is obligatorily restricted to the intermediate host in the sarcosporidian life cycle. micro- and macrogamonts could be distinguished about 12 h post infection and were situat ... | 1979 | 107669 |
| transmission of sarcocystis suihominis from humans to swine to nonhuman primates (pan troglodytes, macaca mulatta, macaca irus). | sporocysts of sarcocystis suihominis obtained from human feces were used to infect swine. heart, tongue, and skeletal muscle from experimentally infected and noninfected control swine were fed via stomach tube to nonhuman primates including chimpanzees (pan troglodytes), rhesus monkeys (macaca mulatta), and cynomolgus monkeys (macaca irus). all primates fed infected swine tissues shed sporocysts beginning 13 to 15 days postinfection and were still shedding sporocysts at the conclusion of the exp ... | 1979 | 113949 |

| sarcocystis suihominis detected for the first time from pigs in japan. | sarcoystis suihominis was detected for the first time in japan from the heart and diaphragm of 5 out 600 older culled breeding pigs slaughtered in saitama prefecture, japan. fresh cysts were 1,080-2,040 x 106-170 microns in size. bradysoites measured 15 x 4 microns on average. the cyst wall was usually observed thick, 4-6 microns, and striated, but occasionally thin and smooth according to the difference in sectioning angle and in portion of cysts. scanning electron microscopy showed that many p ... | 1998 | 9560777 |
| identification of sarcocystis hominis-like (protozoa: sarcocystidae) cyst in water buffalo (bubalus bubalis) based on 18s rrna gene sequences. | dna templates were extracted from isolates of sarcocystis hominis-like cysts collected from cattle and water buffalo, as well as from sarcocystis fusiformis cysts and sarcocystis suihominis cysts. the 18s rrna genes were amplified using dna from a single cyst as the templates. approximately 1,367-1,440 bp sequences were obtained. the sequence difference in isolates of sarcocystis hominis-like cysts from water buffaloes, and isolates of s. hominis cysts from cattle were very low, only about 0.1%, ... | 2001 | 11534667 |

| prevalence of enteric protozoan oocysts with special reference to sarcocystis cruzi among fecal samples of diarrheic immunodeficient patients in iran. | the genus sarcocystis is not usually considered as an important enteric pathogen in immune compromised patients. it might be expected that species for which humans are the final host (sarcocystis hominis and sarcocystis suihominis as well as possibly others) would be encountered increasingly often in immunodeficient persons. this study aimed to address how to detect and differentiate sarcocystis oocysts and/or sporocysts from enteric protozoans in the diarrheal samples of immunodeficient patient ... | 2016 | 27417091 |
| human infections with sarcocystis species. | recurrent outbreaks of muscular sarcocystosis among tourists visiting islands in malaysia have focused international attention on sarcocystosis, a disease once considered rare in humans. sarcocystis species require two hosts, definitive and intermediate, to complete their life cycle. humans can serve as definitive hosts, with intestinal sarcocystosis for two species acquired from eating undercooked meat: sarcocystis hominis, from beef, and sarcocystis suihominis, from pork. symptoms such as naus ... | 2015 | 25715644 |
| detection of zoonotic protozoa toxoplasma gondii and sarcocystis suihominis in wild boars from spain. | food safety regulations require the control of the presence of protozoa in meats destined for human consumption. wild boar (sus scrofa) meat may constitute a source of zoonoses. a 23.8% (688/2881) seroprevalence of anti-toxoplasma gondii antibodies and 72.2% (662/910) sarcocystis sarcocysts prevalence were detected among wild boars hunted in southwestern areas of spain. identity of sarcocystis spp. was performed by rflp-pcr and sequencing, detecting s. miescheriana (7/8) and the zoonotic s. suih ... | 2016 | 26604045 |
| unraveling sarcocystis miescheriana and sarcocystis suihominis infections in wild boar. | sarcocystis species are worldwide spread cyst-forming protozoa that can infect wild boar but little is known about the prevalence of these parasites. in this study we assessed the prevalence of sarcocystis spp. infections in wild boars from northeastern portugal, for which novel pcr testing assays targeting sarcocystis genus, s. miescheriana and s. suihominis were implemented, and risk factors potentially associated with these infections were evaluated. samples from muscle tissue, namely diaphra ... | 2015 | 26319199 |
| in the united states, negligible rates of zoonotic sarcocystosis occur in feral swine that, by contrast, frequently harbour infections with sarcocystis miescheriana, a related parasite contracted from canids. | transmission of pathogens between domestic and wild life animals plays an important role in epidemiology. feral pig populations are increasing and expanding in the usa, and may constitute a risk to non-biosecure domestic pig facilities by serving as reservoirs for pathogens. we surveyed, for sarcocystis infection, the myocardium of 1006 feral pigs (sus scrofa) trapped or hunted in 29 states during the comprehensive feral swine disease surveillance program of the usda's animal and plant health in ... | 2015 | 25363485 |
| morphological and molecular characterization of sarcocystis miescheriana from pigs in the central region of china. | sarcocystosis is an important food-borne parasitosis in humans and various animals. sarcocystis miescheriana and sarcocystis suihominis are pathogenic to pigs; s. suihominis is also distinctly pathogenic to humans. intermediate and final hosts can harbor more than one sarcocystis species, so the exact identification for sarcocystis infection in various hosts is essential to control sarcocystosis in humans and important economic animals including pigs. in this study, four isolates of sarcocysts f ... | 2013 | 23224613 |

| unusual case presentation of intestinal sarcocystis hominis infection in a healthy adult. | sarcocystosis is mainly a veterinary problem; however, humans can serve as the definitive host for at least two species (sarcocystis hominis and sarcocystis suihominis). intestinal infections occur in the definitive host after ingesting the intramuscular cysts (sarcocysts) in the intermediate host, which initiate sexual stages in the intestine that terminate in oocysts excreted in the faeces. | 2014 | 28663816 |
