Table 1 PCR-results with a total of 380 tissue samples obtained from non-infected (control) and N. caninum-infected calves without and with ponazuril therapy (1T = medication for one day; 6T = medication for 6 consecutive days). Bold numbers indicate the number of positive samples per total number of samples analyzed; – means that no sample was PCR-positive. Infected animals without therapy were euthanized on day 45 p.i. (nos. 1–3) and 90 p.i. (nos. 4–6)

From: An explorative study to assess the efficacy of Toltrazuril-sulfone (Ponazuril) in calves experimentally infected with Neospora caninum
