Fungi can be harmful to global health, biodiversity and agriculture and they are responsible for life-threatening diseases, especially in individuals with a weakened immune system. Over the last decades, the number of invasive infections, mainly caused by fungi belonging to Candida, Cryptococcus, Aspergillus and Pneumocystis genera has increased and negatively affected the clinical outcomes of the patients. With regard to all these issues, this book focuses on the processes associated with fungal pathogenesis. The authors believe that this book will serve as a useful reference for consultations with specialists in the Mycology field since it contemplates the most important issues in the proposed area. The chapters are written by experts who actively contribute to international scientific literature. The editors also believe that the theme is a very attractive proposal and the compilation of interesting data will benefit readers in terms of identification, epidemiology, pathogenesis, and treatment of predominant fungal infections around the world. "The Book of Fungal Pathogens" contains 18 chapters, several pictures, diagrams, and tables that can be used in both undergraduate and postgraduate teaching as well as scientific lectures.
