Coccidia have been implicated as another of the many pathogens responsible for scours in baby pigs. The clinical syndrome begins at about 5 days to 3 weeks of age and is similar to other enteritides of neonatal swine. The pigs begin to scour and do not grow well. In some cases, a mortality of up to 50% of those affected has been noted. Negative response to antibiotics normally employed in baby pig scours is often observed as another feature of the disease.
