Table 2 Haematological analyses in the five cats infected with Cytauxzoon sp. Results outside the reference interval are shown in bold font. Cases 1–3 were treated with azithromycin and atovaquone from day 1 to 10 and from day 77 to 86. Case 4 was treated with azithromycin from day 6 to 21 and from day 260 to 270 and with atovaquone from day 11 to 21
