The available drugs against piroplasmosis are insufficient and faced with several challenges, such as drug-resistant parasites and toxicity to treated animals. Therefore, the discovery of new drug compounds is necessary for the effective control of babesiosis and theileriosis. Methanolic Peganum harmala seed extract (MPHSE) and ethanolic Artemisia absinthium leaf extract (EAALE) have several medicinal properties. In the present study, the growth-inhibition effects of MPHSE and EAALE were evaluated in vitro and in vivo. The half-maximal inhibitory concentration (IC50) values for MPHSE against Babesia bovis, B. bigemina, B. divergens, B. caballi, and Theileria equi were 24.9 ± 1.2, 77.1 ± 2.3, 61.1 ± 2.9, 80.8 ± 4.1, and 11.3 ± 2.1 μg/mL, respectively. EAALE exhibited IC50 values of 43.3 ± 3.1, 39.2 ± 2.7, 38.5 ±3.7, 50.3 ± 2.1, and 28.2 ± 2.1 μg/mL against B. bovis, B. bigemina, B. divergens, B. caballi, and T. equi, respectively. The toxicity assay on Madin–Darby bovine kidney (MDBK), mouse embryonic fibroblast (NIH/3T3), and human foreskin fibroblast (HFF) cell lines showed that MPHSE affected the viability of MDBK, NIH/3T3, and HFF cell lines with half maximum effective concentration (EC50) values of 611.7± 10.9, 870 ± 22, and ˃1500 μg/mL, respectively, while EAALE exhibited EC50 values of 340.7 ± 8.5, 736.7 ± 9.3, and 1371.5 ± 17.3 μg/mL against MDBK, NIH/3T3, and HFF cell lines, respectively. In the in vivo experiment, MPHSE and EAALE oral treatments at 150 mg/kg inhibited the growth of Babesia microti in mice by 60% and 55.1%, respectively. These findings suggest that MPHSE and EAALE have the potential to be alternative remedies for treating piroplasmosis.

Development and spread of chloroquine (CQ) resistance led to its withdrawal in most malaria endemic countries. In Kenya, this occurred in 1998 when clinical efficacy dropped below 50%. Less than a decade after CQ was removed from routine use in Malawi, the drug has reversed to activity and is again effective for first-line treatment of uncomplicated malaria. There is a probability of a similar reversed activity in Kenya for more 10 years of its absence in uncomplicated Plasmodium falciparum malaria treatment. The present study was aimed at establishing the CQ resistance status in the country, 10 years after its withdrawal, by looking at high malaria transmission zone, Mbita, a malaria endemic area and some malaria epidemic areas of the Kenyan highlands. The prevalence of T76 and Y86 P. falciparum molecular markers for CQ resistance in Pfcrt and Pfmdr1 genes were investigated by PCR-RFLP and dot blot analysis in 64 samples collected in March to May 2007 in the endemic area and 38 samples collected in April to July the same year in the epidemics. The study shows that 67.3% of field isolates from the endemic site still harbor Y86 mutation in Pfmdr1 while 32.7% have the wild type allele N86 compared to the 94% and 6 % prevalence observed in Mwea, an endemic area, in 2004 (χ 2 =10.08, P=0.00015, 95% CI=2.085-27.8). In the epidemics 75% of field isolates from the epidemic sites still harbor Y86 mutation in Pfmdr1 while 25% have the wild type allele N86 compared to the 91.6% and 8.4% prevalence observed in an epidemic area in 1997 (χ 2 =1.585, P=0.208, 95% CI=0.701-19.176). From the study there is a significant change in the proportions of the resistant genotypes in the endemic areas while in the epidemics, there was also a noticeable shift though not significant. This therefore indicates a slow but steady re-emergence of P. falciparum CQ sensitive strains in the country. Though does not warrant the reintroduction of CQ for malaria treatment.
