Nearly all vertebrate animals host one or more species of the protozoan parasites that produce the infection referred to as coccidiiasis or coccidiosis. Thousands of coccidian species of herbivorous, omnivorous, and carnivorous animals have been described, and many more exist that remain unnamed.
Pasteurellosis is a zoonotic disease. It is caused by infection with bacteria of the Pasteurella genus.

P. multocida is found worldwide.
