During a 3 year period, 186 eastern cottontails (Sylvilagus floridanus) were trapped from two areas and examined for helminth and protozoan parasites. Fecal samples from 139 were evaluated for coccidia and helminth ova. Nine species of coccidia were identified: Eimera audubonii, E. azul, E. environ, E. honessi, E. maior, E. minima, E. neoirresidua, E. neoleporis, and E. sylvilagi. Ova from 5 helminth species were found: Cittotaenia sp., Hasstilesia tricolor, Passalurus sp., a trichostrongyle-type nematode species, and Trichuris sp. Five helminths were recovered from stomachs and small intestines: Cittotaenia sp. H. tricolor, Obeliscoides cuniculi, Passalurus ambiguus, and Trichostrongylus calcaratus.
