An Innovative Method for Determining Amphotericin B Susceptibility in Leishmania infantum Isolates: A Modified Disk Elution Approach

The findings indicate that the modified disk elution method provides comparable reliability to the standard broth microdilution technique. Its low cost, ease of implementation, and visual interpretability make it a promising alternative for drug susceptibility testing, especially in resource-limited laboratories or field settings. Moreover, the use of commercially prepared AmpB disks could facilitate standardization and broader adoption. This study introduces an innovative approach that may simplify routine drug susceptibility screening in Leishmania isolates and support wider surveillance of anti-leishmanial resistance.
