Implication

This study develops an in vitro model using electrical impedance to evaluate antifungal efficacy and cytotoxicity of Aspergillus fumigatus on human cell lines.

Key Points

Higher conidial concentrations of Aspergillus fumigatus led to quicker decreases in electric impedance, indicating more cytotoxicity.
The time for electrical impedance to fall by half was 31.5 hours for low infection levels and 14.1 hours for high levels in macrophages.
Azoles and amphotericin B inhibited electric impedance changes above their minimum inhibitory concentrations, showcasing antifungal efficacy.
This method demonstrates a reliable approach for continuously monitoring interactions between fungi and human cells in vitro.
