Candida glabrata - basic characteristics, virulence, treatment, and resistance

Area of Science:

• Medical Mycology
• Infectious Diseases
• Antimicrobial Resistance

Background:

• Fungal infections, particularly candidiasis, pose a significant threat, especially to immunocompromised individuals.
• Candida albicans remains common, but non-albicans Candida species (e.g., Candida glabrata, Candida auris) are emerging as major pathogens.
• Invasive Candida auris infections are associated with high mortality due to multidrug resistance.

Purpose of the Study:

• To summarize current knowledge on virulence factors and antifungal resistance mechanisms in Candida species.
• To highlight the challenges in managing candidiasis due to emerging resistant strains.
• To emphasize the need for novel antifungal therapeutic targets.

Main Methods:

• Literature review of recent studies on Candida biology and antifungal resistance.
• Analysis of epidemiological trends in fungal infections.
• Synthesis of information on genetic and biochemical mechanisms of azole and multidrug resistance.

Main Results:

• A notable shift in causative agents of candidiasis from Candida albicans to non-albicans Candida species.
• Candida glabrata exhibits inherent azole resistance and a propensity for acquiring resistance to other antifungals.
• Candida auris presents a critical challenge due to its multidrug resistance and high mortality rates.

Conclusions:

• Understanding the distinct biological characteristics and virulence factors of non-albicans Candida is essential.
• The increasing antifungal resistance in Candida species necessitates urgent development of new therapeutic strategies.
• Identifying novel drug targets is paramount for effective management of life-threatening fungal infections.
