Candida albicans-Introduction, Morphology, Pathogenicity, Lab Diagnosis, Treatment, Prevention, and Keynotes

Yeast cells, budding yeasts, and pseudohyphae in KOH mount of sputum microscopic examination

Introduction Candida albicans is a common fungal pathogen in humans. It inhabits mucosal surfaces naturally and colonizes the gastrointestinal tract and genitourinary system frequently. The organism causes infections in both healthy and immunocompromised individuals and adapts quickly to environmental changes within the host. Clinicians report …
