Coccidia of feral swine from Florida.

Fecal samples from 251 free-ranging feral swine (Sus scrofa) in Florida were examined for coccidia. Ten species of coccidia were recovered. In descending order with respect to prevalence, they were Eimeria porci, E debliecki, E neodebliecki, E scarbra, E suis, E cerdonis, E polita, E perminuta, Isospora suis, and E spinosa. Of the swine examined, 87% were passing oocysts and 82% of the infected individuals were shedding at least 2 species of coccidia. All age classes included infected individuals. Statistically significant differences in the prevalence were found among study sites.
