In vitro screening of antifungal compounds able to counteract biofilm development

Area of Science:

• Mycology
• Microbiology
• Drug Discovery

Background:

• Fungal biofilms on inert surfaces and host tissues pose a significant risk for human infections.
• Current therapeutic options against fungal biofilms are limited, necessitating the discovery of new anti-biofilm agents.

Purpose of the Study:

• To describe rapid, 96-well microtiter plate-based methods for screening anti-biofilm compounds.
• To evaluate compounds for their efficacy against Candida spp. biofilms using both prophylactic and curative approaches.

Main Methods:

• Utilized 96-well microtiter plates for high-throughput screening of anti-biofilm compounds.
• Assessed compound activity against Candida biofilms formed on polystyrene surfaces and catheter sections.
• Employed both prophylactic (preventative) and curative treatment strategies.

Main Results:

• Detailed methods for rapid screening of anti-fungal biofilm activity are presented.
• The described methods allow for the evaluation of compounds against Candida biofilms.
• Both prophylactic and curative effects can be assessed on different surfaces.

Conclusions:

• Established robust screening methods for identifying novel anti-biofilm molecules against Candida yeasts.
• The described assays provide a foundation for discovering new therapeutic strategies against fungal biofilm infections.
• These methods facilitate the search for effective agents to combat challenging fungal biofilms.
