ABSTRACT
In the time from September 2003 to March 2004 feacal samples of 147 wild boars from north-west Poland were examined. The prevalence and intensity of the Coccidia and gastro-intestinal nematodes infection were determined by means of Willis-Schlaaf. The species were determined basing on morphology of oocysts (shape, colour, form index, presence or absence of micropyle and its cap, presence or absence of residual, polar and Stied bodies) and time of sporulation. Sporulation was performed in wet chamber at 24-26 degrees C in a 2.5% aqueous solution of potassium dichromate (K2Cr2O7) (Pellerdy, 1974). Oocysts from the genus Eimeria were found in 58.5% wild boars. Four coccidia species occurred in wild boars (E. deblecki, E. suis, E. perminuta, E. scabra). Gastro-intestinal nematodes were found in 83.67%. The following nematode species were found: Oesophagostomum dentatum, Metastrongylus sp., Trichuris suis and Ascaris suum.
