Candida.

Area of Science:

• Mycology and Infectious Diseases
• Medical Microbiology
• Antimicrobial Resistance

Background:

• Fungal infections are a major global health concern, especially for immunocompromised individuals.
• Invasive candidiasis, primarily caused by Candida albicans and emerging species like Candida auris, leads to significant mortality.
• Candida species are classified as critical threat pathogens by the World Health Organization due to their public health importance.

Purpose of the Study:

• To review the biological characteristics of Candida species that facilitate their dual role as commensals and pathogens.
• To focus on the pathogenic mechanisms of Candida albicans and Candida auris.
• To summarize current antifungal therapies and the evolution of resistance mechanisms.

Main Methods:

• Literature review and synthesis of existing research on Candida species biology.
• Analysis of virulence factors, morphological diversity, genotypic plasticity, and stress response pathways.
• Summary of clinical data on invasive candidiasis and antifungal treatment outcomes.

Main Results:

• Candida species possess adaptable traits, including morphological plasticity and robust stress responses, enabling survival in diverse host environments.
• Candida albicans and Candida auris exhibit significant pathogenic potential, contributing to high rates of hospital-acquired infections and mortality.
• Antifungal drug resistance is an evolving challenge, necessitating continuous research into novel therapeutic strategies.

Conclusions:

• Candida species represent a critical threat in human health due to their adaptability and increasing drug resistance.
• Further research into Candida biology is essential for developing effective treatments against invasive infections.
• Addressing antifungal resistance is paramount to improving patient outcomes and public health.
