How many types of pathogenic bacteria are there?
In total, there are ∼1,400 known species of human pathogens (including viruses, bacteria, fungi, protozoa and helminths), and although this may seem like a large number, human pathogens account for much less than 1% of the total number of microbial species on the planet.
What are the four types of pathogen?
Pathogen types. There are different types of pathogens, but we’re going to focus on the four most common types: viruses, bacteria, fungi, and parasites. Viruses are made up of a piece of genetic code, such as DNA or RNA , and protected by a coating of protein. Once you’re infected, viruses invade host cells within your body.
