Parasite culture growth at 24 h (purple bars), 48 h (blue bars) and 72 h (yellow bars) without and after addition of different concentrations of endochin-like quinolone-300 (ELQ-300). a Babesia bovis, b B. bigemina c B. caballi, d Theilera equi. “0” represents parasites in the absence of ELQ-300. Assays were carried out in triplicate, and the error bars indicate standard error deviation for each ELQ-300 concentration tested. Asterisk (*) represents statistically significant difference between cultures grown without and with ELQ-300 at P < 0.05, using Student’s t-test. nRBC Non-infected erythrocytes, PPE percentage of parasitized erythrocytes
