Abstract:
One billion people worldwide are affected by fungal pathogens, of which 1.6 million succumb to fungal infections per year. This review discusses the emergence and evolution of fungal pathogenesis in humans in the form of opportunistic commensal and environmental fungi. We explore the attributes that contribute to their success as pathogens and the scenarios which may have caused the evolutionary selection of virulence factors. This includes antivirulence and avirulence genes, notions that are new for fungal pathogens of humans but which are based on well established concepts in bacterial pathogens and phytopathogenic fungi. These ideas will ultimately help us to better understand the pathogenicity of fungi that infect humans: from the emergence to the finer adjustment of virulence to promote pathogen persistence.
Insights
Fungal infections impact a billion people globally each year. This review explores how fungi evolve to cause disease, focusing on virulence factors and pathogen persistence.
Area of Science:
- Medical Mycology
- Evolutionary Biology
- Pathogenomics
Background:
- Fungal pathogens affect one billion people globally, causing 1.6 million deaths annually.
- Human fungal infections arise from opportunistic commensals and environmental fungi.
- Understanding fungal pathogenesis is crucial due to its significant public health impact.
Purpose of the Study:
- To review the emergence and evolution of fungal pathogenesis in humans.
- To explore attributes contributing to fungal pathogen success and virulence factor evolution.
- To introduce concepts of antivirulence and avirulence genes in human fungal pathogens.
Main Methods:
- Literature review of fungal pathogenesis, evolution, and virulence factors.
- Analysis of established concepts from bacterial and plant pathogenic fungi.
- Exploration of genetic factors influencing fungal pathogenicity.
Main Results:
- Fungi possess specific attributes enabling them to become successful human pathogens.
- Evolutionary pressures may drive the selection of virulence factors in fungi.
- Antivirulence and avirulence genes offer new perspectives on fungal pathogenicity.
Conclusions:
- Understanding fungal evolution, including antivirulence, enhances knowledge of human fungal infections.
- This framework aids in comprehending fungal pathogenicity from emergence to persistence.
- Further research into fungal virulence and avirulence mechanisms is warranted.

Infection
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...

Phagocytes
Phagocytes are the frontline soldiers of the immune system. They include neutrophils and macrophages. Neutrophils are the most abundant type of white blood cell and are quickly mobilized to the site of infection. Macrophages are larger cells that patrol...
