**Preface to "***Candida albicans***: A Major Fungal Pathogen of Humans"**

Despite the tremendous advances being achieved in our understanding of the molecular mechanisms that underpin host–pathogen interactions, *Candida albicans* continues to be the most prevalent of life-threatening fungal pathogens. Exquisitely fine-tuned environmental sensing combined with genetic plasticity and the ability to rapidly adapt to the multiple niches of the human body make *C. albicans* a major adversary in medical mycology.

This book aims to highlight the increasing global threat posed by *C. albicans* and raise awareness of ongoing research which aims to combat *C. albicans* infections. Review articles and primary research are combined to showcase the current state of play regarding morphological switching, nutrient sensing and metabolism, and the impact of *C. albicans* infections on neonates. Current research investigating antifungal host responses and strategies toward the development of antifungal agents is also presented.

This Special Issue is aimed at those interested in *Candida albicans* biology, host–pathogen interactions, and medical mycology. I would like to thank all of the authors who contributed to this Special Issue. Your dedication and expertise are appreciated.
