| cryptosporidium from tortoises: genetic characterisation, phylogeny and zoonotic implications. | cryptosporidiosis is a disease caused by apicomplexan parasites of the genus cryptosporidium, which affect the gastrointestinal tract of humans and animals worldwide. in the present study, cryptosporidium isolates from captive european tortoises (testudo graeca, testudo hermanni and testudo marginata) in italy were genetically characterised using gene/s encoding cryptosporidium oocyst wall protein (cowp) and/or the hypervariable segment internal to the ssu rdna. six isolates from t. graeca, t. h ... | 2008 | 18234467 |
