Case report: The clinical and laboratory findings in an orphanedjuvenile female platypus (Ornithorhynchus anatinus) that presentedwith a severe anaemia and tick infestation are reported. The animaldeveloped a terminal septicaemia and died. Antemortem clinicalpathology, postmortem histopathology and 18S rDNA sequencingsupported a diagnosis of extravascular haemolytic anaemia secondaryto Theileria ornithorhynchi infection. Conclusion: Although T. ornithorhynchi infection is common inthe platypus, this is the first case in which it has been shown tocause a haemolytic anaemia in this species and molecularcharacterisation of the organism has been described. A review ofthe previous literature concerning T. ornithorhynchi and possibletreatment options for future cases are discussed.
