Establishment of Fascioloides magna in a new region of Hungary: case report.

During the monitoring of red deer (N = 124) and fallow deer (N = 13) populations in four neighbouring areas, the presence of Fascioloides magna was confirmed in southwestern Hungary. The prevalence and the mean intensity of the infection within the host populations ranged between 0 and 100% and 0-36.3, respectively. The determined prevalences are similar to that observed earlier in other European natural foci. The authors hypothesise that the appearance of F. magna in this region should have been a partly natural- and partly human-influenced process.
