Summary Fascioloidosis of wild and domestic ruminants is caused by giant liver fluke, Fascioloides magna (Trematoda; Fasciolidae). In Slovakia, the parasite is present in the Danube floodplain forests permanent focus for almost 30 years. Here we provide data on 11-year survey of F. magna acquired from 137 red deer ( Cervus elaphus ) hunted in the southwestern hunting grounds (districts Komárno and Dunajská Streda). Almost 47 % of all examined deer, including males, females and fawns, were infected with F. magna . During the studied period, the prevalence ranged between 33.3 % (2009) and 63.6 % (2007). Prevalence of fascioloidosis varied between sexes and age categories; while the lowest overall prevalence was detected in females (33.3 %), higher values were documented for red deer males (50.6 %) and fawns (43.3 %). A presence of giant liver fluke in studied regions of southwestern Slovakia deserves future attention and ongoing monitoring due to a possible threat of F. magna infection of domestic ruminants in overlapping regions.
