Figure 3: Results of effect in vitro, percentage of inhibition of two strains (P-I and WB ) of Giardia intestinalis axenically cultured treated with different concentrations of kramecyne (K), LD502 value = 40 μg/mL for both strains. Percentages of inhibition of P-I and P-I(r) are also observed (LD501 = 12 and LD503 = 70 μg/mL, resp.).
