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

Fungal infections are currently a serious health concern. Life-threatening conditions that occur mainly in immunocompromised patients are largely caused by representatives of the genus Candida. The most common causative agent is the yeast Candida albicans, but in recent years there has been a significant shift towards Candida glabrata and other so-called non-albicans Candida yeasts (e.g. Candida tropicalis or Candida parapsilosis). Invasive infections caused by the multidrug-resistant yeast Candida auris are associated with high mortality. There are several differences between C. glabrata and other causative agents of candidiasis in biological characteristics and virulence factors. The innate increased resistance to azoles along with the ability to rapidly acquire resistance to other groups of antifungal agents is a dangerous combination which makes it difficult to manage Candida infections. A better understanding of the virulence factors and mechanisms of resistance to antifungal agents can benefit the management of Candida infections. Equally important is the search for new target sites for antifungal therapy. The present work briefly summarizes the existing knowledge in this area.
