Prevalence and diversity of spp. in free-range chickens in northeastern Brazil.

In tropical regions, family farming is a form of production and work that is highly present in rural areas. Because the production system for free-range chickens has a low level of technification, it frequently presents massive infection by coccidia. The objective of this study was to determine the prevalence and diversity of species in free-range chickens in northeastern Brazil.
