Fungal pathogens are microorganisms that can cause diseases in plants, animals, and humans. They belong to the kingdom Fungi and can thrive in various environments. Some common examples include Candida species, which can lead to infections in humans, and Aspergillus, known for causing respiratory issues. These pathogens can enter the body through cuts, inhalation, or ingestion. Once inside, they can multiply and disrupt normal biological functions. Fungal infections can range from mild to severe, depending on the individual's immune system and the type of fungus involved. Proper hygiene and medical treatment are essential for prevention and management.
