Occurence of Echinococcus multilocularis in red foxes (Vulpes vulpes) in southern Poland

Abstract The prevalence of Echinococcus multilocularis in 214 red foxes (Vulpes vulpes) in the southern part of Poland (Małopolskie voivodship) was evaluated post mortem in 2005. Infected foxes were found in 8 districts within 17 examined, with the prevalence from 10.0 % to 63.9 % (a mean 20.1 % in the whole study area). The highest prevalence (41.2 % and 63.9 %) was revealed in two districts, in the south and the east of the province, respectively. The high prevalence of E. multilocularis in red foxes in the region previously recognised as that of low parasite endemicity provides evidence for the need of regular screening of the current epidemiological situation in foxes as well as the monitoring of humans from risk groups for early recognition of possible AE cases.
