: The study were carried out in the years 2006-2007 on 57 semi-free living hares. The faeces of these animals were examined by the flotation and McMaster methods. All hares were infected with coccidia. Following six Eimeria species were found: E. leporis, E. europaea, E. robertsoni, E. semisculpta, E. townsendi and E. hungarica. The invasion of the species E. leporis, E. europaea and E. robertsoni were characterized of the highest intensity.
