ABSTRACT
Background and Purpose:
Taurolidine is active against a wide variety of micro-organisms, including bacteria and fungi. Mucormycosis is one of the life-threatening opportunistic fungal infections, especially in immunocompromised patients. Currently, the emergence of Mucormycosis during the COVID-19 pandemic raises public health concerns regarding untoward morbidity and mortality among SARS-CoV-2 patients. It is well-known that delayed and inappropriate antifungal therapy leads to increased morbidity and mortality. This study aimed to investigate the in-vitro antifungal activity of taurolidine to evaluate its effects against clinical isolates of Mucorales. Materials andMethods:
This study included previously collected clinical Mucorales isolates. The minimum in vitro inhibitory concentration (MIC) of amphotericin B, caspofungin, voriconazole, posaconazole, and itraconazole was determined using the broth microdilution method.Results:
All clinical isolates showed full sensitivity to amphotericin B. Posaconazole MIC range from 8 µg/mL to 0.032 µg/mL. The MIC range of voriconazole and caspofungin were determined to be 2-8 µg/mL and 0.5-16 µg/mL, respectively. Growth of the isolates was entirely inhibited in 1000 µg/mL concentration of taurolidine. In microscopic observations, morphological effects on hyphal growth were observed at 500 µg/mL concentration.Conclusion:
In conclusion, this is an updated experience of using taurolidine against Mucorales. However, our in-vitro findings need to be confirmed in well-designed clinical trials aimed at treating invasive Mucormycosis infections.
