Members of the genus Trichobilharzia are parasitic in visceral or nasal body parts of their avian hosts. The examination of water snails in South Bohemia revealed a schistosome infection in Radix peregra snails. The experimental infection of ducklings (Anas platyrhynchos, Cairina moschata) confirmed that a new Trichobilharzia species - T. regenti n. sp. - was found. The adults, eggs and larvae (miracidia and cercariae) of the species were morphologically characterized. The adults occupy the nasal blood vessels where they lay the eggs; the miracidia hatch from the eggs directly in the tissue and leave the host during drinking/feeding of the infected birds.
Résumé
Les membres du genre Trichobilharzia parasitent les régions viscérale et nasale de leurs hôtes aviaires. L'examen de mollusques d'eau douce en Bohème du Sud a montré une infestation par schistosome de Radix peregra .L'infestation expérimentale de canetons (Anas platyrhynchos, Cairina moschata) confirme la découverte d'une nouvelle espèce de Trichobilharzia, T. regenti n. sp. Les formes adultes, les oeufs et les larves (miracidies et cercaires) de l'espèce sont caractérisés sur le plan morphologique. Les adultes occupent les vaisseaux sanguins nasaux où ils déposent leurs œufs; les miracidies éclosent directement dans les tissus et quittent l'hôte quand les oiseaux infectés boivent ou s'alimentent.
