(Rathke, 1862) as a vector of potentially pathogenic fungi in aquatic ecosystems.

The aim of the study was to check the integument and alimentary tract of for the occurrence of fungi. Moreover, the mycological purity of water sources from which leeches were collected was analyzed. The potential role of the duck leech in transmitting pathogenic fungi has not been studied until now.

Sucking of human blood by (O. F. Müller, 1846) (Hirudinida: Glossiphoniidae): Case study with notes on body form.

Four events of sucking human blood are described.Human blood was sucked by both adult and juvenile specimens of . .

New record of the fish leech (Annelida: Hirudinida: Piscicolidae) - DNA barcoding and phylogeny.

The aim of this study was to confirm the taxonomic status of Bielecki, 1994 found on Salmonidae fish. The fish leech was identified based on a diligent morphological analysis as well as COI gene sequence (DNA barcoding). The phylogenetic relationship with other piscicolid leeches was analyzed as well.
