Abstract

Nerolidol is a sesquiterpene present in the essential oils of many plants, approved by the U.S. FDA as a food flavoring agent. Nerolidol interferes with the isoprenoid biosynthetic pathway in the apicoplast of P. falciparum. In the present study, the in vitro growth of four Babesia species was significantly (P < 0.05) inhibited in the presence of nerolidol (IC50s values = 21 ± 1, 29.6 ± 3, 26.9 ± 2, and 23.1 ± 1 µM for B. bovis, B. bigemina, B. ovata, and B. caballi, respectively). Parasites from treated cultures failed to grow in the subsequent viability test at a concentration of 50 µM. Nerolidol significantly (P < 0.05) inhibited the growth of B. microti at the dosage of 10 and 100 mg/kg BW, while the inhibition was low compared with the high doses used. Therefore, nerolidol could not be used as a chemotherapeutic drug for babesiosis.
