Abstract:
Growing rates of immunodeficiency diseases, immunosuppression after transplantation, cancer, and cancer therapy are all contributing to the rise in fungal infections. They are widespread and may produce minor infections or more serious, deeply ingrained diseases that are fatal. Numerous virulence factors that support the survival and duration of the fungal infection cause tissue damage and illness within the host, these virulence factors are covered in this review. These elements include the capacity to cling to the tissues of hosts, the generation of tissue-damaging enzymes, and the direct disruption of host defense mechanisms. Mannitol and catalases are two substances produced by pathogenic fungi that offer protection against reactive oxygen species (ROS). Certain fungi such as Candida. albicans and dimorphic fungi are capable of changing their morphology. In a mammalian host, thermotolerance of at least 37°C is essential for life and aids in spread. Several pathogenic fungi synthesize melanin, which protects from extreme elements including UV rays, high temperatures, and ROS, another virulence determinant is the capacity of the host to access iron (Fe) in the storage or transport forms, and calcineurin functions as a pathogenic fungal sensor.
