| cryptosporidium xiaoi n. sp. (apicomplexa: cryptosporidiidae) in sheep (ovis aries). | a new species, cryptosporidium xiaoi, is described from sheep. oocysts of c. xiaoi, previously identified as the cryptosporidium bovis-like genotype or as c. bovis from sheep in spain, tunisia, united kingdom, and the united states are recorded as such in genbank (eu408314-eu408317, eu327318-eu327320, ef362478, ef514234, dq991389, and ef158461). oocysts obtained from naturally infected sheep were infectious for a lamb and oocysts from that lamb were infectious for three other lambs. the prepaten ... | 2009 | 19501967 |
| cryptosporidium infection in non-human hosts in malawi. | of 1346 faecal samples from the chikwawa and thyolo districts of malawi, analysed for the presence of cryptosporidium oocysts between october 2001 and may 2003, 61.3% were from cattle (29.8% of these were from calves <6 months old). cryptosporidium oocysts were detected during all three seasons studied in chikwawa and thyolo. in chikwawa, 13.6% of adult cattle and 11.7% of calves were infected, compared to 28.9% of adult cattle and 36.7% of calves in thyolo. dependent on season, between 7.8% and ... | 2009 | 21344786 |
| cryptosporidium ryanae n. sp. (apicomplexa: cryptosporidiidae) in cattle (bos taurus). | a new species, cryptosporidium ryanae, is described from cattle. oocysts of c. ryanae, previously identified as the cryptosporidium deer-like genotype and recorded as such in genbank (ay587166, eu203216, dq182597, ay741309, and dq871345), are similar to those of cryptosporidium parvum and cryptosporidium bovis but smaller. this genotype has been reported to be prevalent in cattle worldwide. oocysts obtained from a calf for the present study are the smallest cryptosporidium oocysts reported in ma ... | 2008 | 18583057 |
| detection and molecular characterization of cryptosporidium bovis-like isolate from a newborn lamb in spain. | species of cryptosporidium infect a broad variety of animals. because morphological features of the secreted oocysts are not useful in identifying the parasite at the species level, molecular tools were used to accomplish this task, leading to discovery of new cryptosporidium species. with the use of this approach, cryptosporidium bovis has recently been described as a new species infecting bovines and several other hosts, but clearly distinct from c. parvum. in this report, we present a descrip ... | 2007 | 18314710 |
| cryptosporidium bovis n. sp. (apicomplexa: cryptosporidiidae) in cattle (bos taurus). | a new species of cryptosporidium, c. bovis, is described. oocysts of c. bovis, previously identified as cryptosporidium genotype bovine b (genbank ay120911), are morphologically indistinguishable from those of c. parvum. they are excreted fully sporulated and contain 4 sporozoites, but lack sporocysts. oocysts measure 4.76-5.35 microm (mean = 4.89 microm) x 4.17-4.76 microm (mean = 4.63 microm), with a length-to-width ratio of 1.06 (n = 50). oocysts were not infectious for neonatal balb/ c mice, ... | 2005 | 16108557 |
