Fungal parasites are organisms that rely on a host to obtain nutrients, often harming the host in the process. They can infect plants, animals, and humans, leading to various diseases. Common examples include Candida, which can cause infections in humans, and Batrachochytrium dendrobatidis, a fungus that affects amphibians. These parasites reproduce by releasing spores, which can spread through the air, water, or direct contact. Once they find a suitable host, they invade tissues and absorb nutrients, weakening the host's health. Understanding fungal parasites is essential for managing their impact on ecosystems and human health.
