The Caenorhabditis elegans egg hatching methodology is a valuable tool for assessing the anthelmintic activity of drugs and compounds and evaluating anthelmintic drug efficacy.Isolated eggs from gravid adults are exposed to different concentrations of selected drugs and the percentage of egg hatching is determined with respect to the control condition. The assay allows the construction of concentration-response curves and determination of EC50 or EC90 values for egg hatching inhibition. Also, it allows measurements of inhibition as a function of time of exposure.This approach addresses the urgent need for new anthelmintics, as resistance to current treatments poses a significant challenge in parasitic nematode infection. This resistance not only affects humans but also animals and plants, causing significant economic losses in livestock farming and agriculture.By using the free-living nematode C. elegans as a parasitic model organism, researchers can efficiently screen for potential treatments and assess drug combinations for synergistic effects. Importantly, this assay offers a cost-effective and accessible alternative to traditional methods, eliminating the need for specialized infrastructure, hosts, and trained animal maintenance personnel. Additionally, the methodology closely mimics natural conditions, providing insights into egg development and potential therapeutic targets.This method allows for evaluating the direct negative impact of drugs on egg hatching, which correlates with long-term anthelmintic effects, offering advantages in preventing or reducing the transmission and spread of worm infections by eggs.Overall, this approach represents a significant advancement for anthelmintic discovery, offering both practical applications and avenues for further scientific research. • The C. elegans egg hatching assay is a robust and effective method for assessing the anthelmintic potential of various drugs and compounds, allowing the generation of concentration-response curves. • By leveraging the free-living nematode C. elegans as a parasitic model organism, this method facilitates efficient screening of potential treatments and evaluation of drug combinations. • The method addresses the urgent need for new anthelmintics, offering a cost-effective and accessible alternative to traditional approaches. |
