Course of PCV and Cytauxzoon sp. parasitaemia in Cases 1–3. The PCV (solid lines) and Cytauxzoon sp. parasitaemia (dashed lines) during 133 days following presentation are shown. The time-span during which the cats received medical therapy with atovaquone and azithromycin (days 1–10 and days 77–86) is indicated with a grey box. The Cytauxzoon sp. parasitaemia is represented by the cycle threshold (Ct) value of the real-time PCR. The Ct value is inversely proportional to the relative amount of target nucleic acid in the real-time PCR reaction
