Abstract
Background
Although Guiera senegalensis is used as a dewormer in ethnoveterinary health care in Nigeria, its anthelmintic potential has not been validated. Hence, this work investigated the in vitro anthelmintic potential of G. senegalensis extracts on two Caenorhabditis elegans strains: Bristol N2 (wild type/ivermectin susceptible) and DA1316 (ivermectin resistant).
Results
Aqueous and methanol extracts of G. senegalensis were tested against the motility of the L4 larvae at two exposure periods of 24 and 48 h and found to be active against the C. elegans strains. Motility of C. elegans DA1316 was reduced to 18.6% and 8.3% by aqueous and methanol extracts, respectively, at 2.0 mg/ml after 48 h, whereas that of C. elegans DA1316 treated with ivermectin (0.02 µg/ml) remained above 95%. The motility of C. elegans Bristol N2 was reduced to 16.6% and 7.2% by aqueous and methanol extracts, respectively, at 2.0 mg/ml after 48 h and ≤ 2.7% by ivermectin (0.02 µg/ml). Activity of the plant extracts was concentration and time dependent.
Conclusions
This work confirms the anthelmintic activity of G. senegalensis and its effectiveness against ivermectin-resistant nematodes, thus validating its ethnoveterinary use as an animal dewormer in Nigeria and pharmacological potential as a source of anthelmintic compounds against ivermectin-resistant nematodes. There is, however, the need for in vivo studies to confirm the in vitro efficacy of the extracts.
