Definition
The Order Coccidia is a large group within the Apicomplexa phylum, comprising parasitic protozoans that infect a wide range of animals. They are characterized by their intracellular parasitic lifestyle, mainly within the intestinal tract. Think of them as a diverse gang of parasites causing trouble for various animals. They are distinct from other parasitic orders by their specific reproductive methods and host preferences. This order is like a criminal syndicate, each family (genus) specializing in different crimes (infections). They have significant impacts on animal health and agriculture.
