Protozoal Infections FAQ

What is a protozoan infection?

Protozoan infections are responsible for a wide range of different diseases that affect not only humans but animals and plants as well.

What are common protozoan infectious diseases?

Common protozoan infectious diseases include malaria, giardia, and toxoplasmosis. Less common diseases include African trypanosomiasis and Amoebic dysentery. Each condition affects the body differently. Unlike other pathogens, cultures do not identify protozoa.

What is a protozoan pathogen?
