theileria ornithorhynchi mackerras, 1959 in the platypus, ornithorhynchus anatinus (shaw). | blood smears from 54 platypuses in southeastern australia were examined by light microscopy. protozoa were found in erythrocytes in 53 platypuses; all infections were sparse. a few parasites were found in leukocytes. intraerythrocytic forms examined by electron microscopy contained vacuoles, micronemes, rhoptries and cytostomes with double unit membranes. merozoites were identified in leukocytes. the parasites were identified as theileria ornithorhynchi mackerras, 1959. | 1986 | 3951057 |
haemolytic anaemia associated with theileria sp. in an orphaned platypus. | the clinical and laboratory findings in an orphaned juvenile female platypus (ornithorhynchus anatinus) that presented with a severe anaemia and tick infestation are reported. the animal developed a terminal septicaemia and died. antemortem clinical pathology, postmortem histopathology and 18s rdna sequencing supported a diagnosis of extravascular haemolytic anaemia secondary to theileria ornithorhynchi infection. | 2014 | 25123825 |
deep-sequencing to resolve complex diversity of apicomplexan parasites in platypuses and echidnas: proof of principle for wildlife disease investigation. | the short-beaked echidna (tachyglossus aculeatus) and the platypus (ornithorhynchus anatinus) are iconic egg-laying monotremes (mammalia: monotremata) from australasia. the aim of this study was to demonstrate the utility of diversity profiles in disease investigations of monotremes. using small subunit (18s) rdna amplicon deep-sequencing we demonstrated the presence of apicomplexan parasites and confirmed by direct and cloned amplicon gene sequencing theileria ornithorhynchi, theileria tachyglo ... | 2017 | 28919547 |
first molecular characterization of theileria ornithorhynchi mackerras, 1959: yet another challenge to the systematics of the piroplasms. | piroplasms, tick-transmitted apicomplexa of the genera theileria, babesia and cytauxzoon, are blood-borne parasites of clinical and veterinary importance. the order piroplasmida shows a puzzling systematics characterized by multiple clades, soft polytomies and paraphyletic/polyphyletic genera. in the present study, screening of platypuses (ornithorhynchus anatinus), was performed to infer the parasite molecular phylogeny. dna was extracted from blood, ectoparasites and tick eggs and the 18s rrna ... | 2015 | 26599724 |
