| cryptosporidium tyzzeri and cryptosporidium muris originated from wild west-european house mice (mus musculus domesticus) and east-european house mice (mus musculus musculus) are non-infectious for pigs. | three and 8 week old pigs were inoculated with cryptosporidium muris hz206 (mus musculus musculus isolate), cryptosporidium tyzerri cr2090 (m. m. musculus isolate) or c. tyzzeri cr4293 (isolate from a hybrid between mus musculus domesticus and m. m. musculus) at a dose of 1 × 10(7) oocysts per animal. inoculated pigs showed no detectable infection and no clinical symptoms of cryptosporidiosis during 30 days post infection (dpi), and no macroscopic changes were detected in the digestive tract fol ... | 2012 | 22465334 |
| coevolution of cryptosporidium tyzzeri and the house mouse (mus musculus). | two house mouse subspecies occur in europe, eastern and northern mus musculus musculus (mmm) and western and southern mus musculus domesticus (mmd). a secondary hybrid zone occurs where their ranges meet, running from scandinavia to the black sea. in this paper, we tested a hypothesis that the apicomplexan protozoan species cryptosporidium tyzzeri has coevolved with the house mouse. more specifically, we assessed to what extent the evolution of this parasite mirrors divergence of the two subspec ... | 2013 | 23791796 |
| the detection of cryptosporidium serpentis in snake fecal samples by real-time pcr. | infection by cryptosporidium serpentis occurs in reptiles, particularly in snakes. this disease is characterized by chronic infection with the presence of hypertrophic gastritis. the objectives of this study were to use real-time polymerase chain reaction (pcr) targeting the heat shock protein 70 (hsp70) gene for the detection of c. serpentis in fecal samples from snakes and to determine the analytical and epidemiological specificity and sensitivity of this approach relative to the gold standard ... | 2014 | 24880646 |
| genetic diversity of cryptosporidium spp. including novel identification of the cryptosporidium muris and cryptosporidium tyzzeri in horses in the czech republic and poland. | faecal samples were collected from 352 horses on 23 farms operating under six different management systems in the czech republic and poland during 2011 and 2012. farms were selected without previous knowledge of parasitological status. all faecal samples were screened for cryptosporidium spp. presence using microscopy, following aniline-carbol-methyl violet staining and pcr analysis of the small-subunit (ssu) rrna and the 60-kda glycoprotein (gp60) genes. cryptosporidium muris-positive samples w ... | 2015 | 25722018 |

| cryptosporidium tyzzeri n. sp. (apicomplexa: cryptosporidiidae) in domestic mice (mus musculus). | the cryptosporidium in the small intestine of domestic mice (mus musculus) was initially described as cryptosporidium parvum. recent genetic and biologic characterization of cryptosporidium isolates indicate that domestic mice are infected with several morphologically indistinguishable intestinal cryptosporidium parasites with different host specificities, including c. parvum sensu stricto, mouse genotype i, and mouse genotype ii. in this study, the morphological, biological, and genetic charact ... | 2011 | 21803038 |

| human cryptosporidiosis caused by cryptosporidium tyzzeri and c. parvum isolates presumably transmitted from wild mice. | we report a case of severe human cryptosporidiosis caused by cryptosporidium tyzzeri and c. parvum with an unusually high frequency of liquid stools. wild mice were the most likely source of infection, demonstrating the potential for wild-mouse-borne cryptosporidium to infect humans and highlighting the health risks associated with synantropic rodents. | 2013 | 23100342 |
