What are the types of phatogens?

Pathogens are classified into several main types: bacteria, viruses, fungi, parasites, and prions. Bacteria are single-celled organisms that can cause diseases like strep throat, while viruses, which require a host to replicate, are responsible for illnesses such as influenza. Fungi can cause infections like athlete's foot, and parasites, like protozoa and worms, live on or in a host and can lead to diseases such as malaria. Prions are misfolded proteins that can induce abnormal folding of normal proteins in the brain, leading to neurodegenerative diseases.
