| The in vitro inhibitory effect of fosmidomycin was evaluated against the asexual growth of bovine Babesia parasites (Babesia bovis and Babesia bigemina). In the cultures with these parasites, severe reduction of parasite growth was observed by the addition of 1.25 μg/ml of the final drug concentration. Under these conditions, B. bigemina was completely cleared until the third day of cultivation. On the other hand, B. bovis was completely eliminated on the fourth day when the concentration was 6.25 μg/ml in the culture. These parasites failed to grow again when a drug-free medium was substituted for the subsequent cultivation. The IC50 values of fosmidomycin against B. bovis were determined as 0.88 and 0.63 μg/ml in the in vitro cultures with... |

| Apicidin, a histone deacetylase inhibitor, has a broad spectrum of anti-protozoal activities against apicomplexan parasites. In the present study, we evaluated the inhibitory effect of apicidin on the asexual growth of bovine Babesia parasites (B. bovis and B. bigemina) in vitro, as well as on the in vivo growth of B. microti in mice. The growth of B. bovis and B. bigemina was significantly inhibited in the presence of 3 ng/ml apicidin. Complete inhibition of B. bovis and B. bigemina growth was achieved on the fourth and third days, respectively, after treatment with 729 ng/ml apicidin. These parasites failed to grow again even when drug-free medium was substituted. The 50% inhibitory concentrations of apicidin against B. bovis and B. bigemina were... |
