The first report of sparganosis (Spirometra sp.) in Eurasian badger (Meles meles).

Spirometra sp. is a diphyllobothriid cestode which reproduces mainly in cat-like carnivores and canids. Several animal species that are not definitive hosts function as paratenic hosts, in which plerocercoids migrate to other tissues causing sparganosis. In this paper we describe the first case of sparganosis (Spirometra sp.) in Eurasian badger (Meles meles). It was found in an adult female Eurasian badger killed on the road in the Białowieża Primeval Forest (north-eastern Poland) in April 2013. At necropsy, 128 complete and 40 fragments of plerocercoids (spargana) were found and were located subcutaneously, mainly on the hind legs and along the spine. The average length of spargana was 87±38mm. No adult Spirometra sp. tapeworms were found in the animal intestine, indicating that the investigated badger was a paratenic host for Spirometra sp. Analysis of 18S rRNA gene sequences combined with morphological examination confirmed affiliation of the concerned plerocercoids to genus Spirometra.
