In vitro anti-parasitic effects of different exposure periods and different drug concentrations. For different exposure period, parasites were exposed for 20, 40 and 60 min with formalin-H₂O₂ or formalin-bronopol combinations a. For different concentrations, parasites were exposed for 30 min with formalin-H₂O₂ and formalin-bronopol at 5, 10 or 20 ppm of total drug concentrations b. The ratios in both tests were 4:1 ppm. n = 3
