Abstract

Introduction: The present work aimed to assess the anti-parasitic effects of limonene (LMN) against Giardia lamblia trophozoites and cysts.

Methods: Anti-Giardia activities of LMN (25, 50, and 100 µg/mL) were assessed against G. lamblia cysts and trophozoites for 15-360 minutes. The effects of LMN on the apoptosis stimulation G. lamblia parasites were determined by colorimetric protease assay.

Results: Giardia trophozoites were more sensitive to LMN than cysts. The best effect of LMN was seen at 100 μg/mL. LMN markedly triggered caspase-3 activity by 10.2%, 25.3%, and 36.1%, respectively (P<0.001).

Conclusion: We found the potent in vitro anti-giardia activity of LMN against G. lamblia parasites with the maximum activity at 50 and 100 µg/mL. However, additional surveys are necessary to reveal the specific efficacy, mechanisms, and safety of LMN.


Implication for health policy/practice/research/medical education:

This work revealed the potent in vitro anti-Giardia activity of limonene (LMN) against G. lamblia with the maximum activity at 50 and 100 µg/mL. We also showed that induction of apoptosis could be considered as one of the cellular mechanisms of action of limonene; nevertheless, additional surveys are necessary to consider it as a new drug.
