Abstract
During 2006-2008, fresh faecal samples of European ground squirrels (Spermophillus citellus) from all available localities in the Czech Republic and several localities in Slovakia were collected and examined for the presence of endoparasites. Oocysts of the genus Eimeria (Apicomplexa: Eimeriorina: Eimeriidae) were found in all examined samples (prevalence 100%).
Three different Eimeria species were recorded. Furthermore, Trichuris eggs (Nematoda: Enoplida) and oocysts of psedoparasites of the genus Adelina were found in some samples.
Stains for Cryptosporidium were negative in all samples.
