Background: Cytauxzoonosis is an emerging and life-threatening tick-borne feline disease caused by haemoprotozoan parasites of the genus Cytauxzoon. Information regarding epidemiological and clinical presentation of infections by species other than Cytauxzoon felis is scant. A case of Cytauxzoon sp. infection is described in a 2-year-old mixed breed male domestic cat from Portugal, presenting a history of acute lethargy, anorexia and pyrexia. Results: Complete blood count revealed a severe anaemia, leucocytosis and thrombocytopenia. A pleural effusion was noticed on thoracic radiograph, and marked splenomegaly and free abdominal fluid were visualized by ultrasound. A molecular screening for the detection of causative agents of infectious anaemia was performed, and a positive result for Piroplasmorida was obtained. DNA sequencing of a 743 bp amplicon of the 18S rRNA gene (GenBank accession no. KU710344) revealed 99.9 % identity with Cytauxzoon manul. Conclusions: This is the first report of Cytauxzoon sp. (clustering together with C. manul) in a felid from Portugal. Clinical manifestations along with molecular analysis suggest the hypothesis that domestic cats might be infected with and serve as a reservoir host for C. manul.
