“…Prosobranch and pulmonate snail species of the families Planorbiidae and Lymnaeidae may serve as the first intermediate hosts ( Szidat, 1939 ; Zhytova & Korol, 2012 ). In Central Europe, larval development of the parasite occurs specifically in great pond snail Lymnaea stagnalis and ram’s horn snail Planorbis planorbis ( Grabda-Kazubska et al , 1990 ; Faltýnková et al , 2008 ; Zhytova & Korol, 2012 ), which are commonly found in permanent swamps often visited by storks. Cercariae develop in typical echinostomatid rediae in snails and penetrate the second intermediate hosts, amphibian tadpoles.…”

Summary An injured young individual of the Eastern Imperial Eagle (Aquila heliaca; Accipitridae) from the Protected Bird Area „Medzibodrožie” in the south-eastern Slovakia was subjected to the complete clinical examination at the Clinic for Birds and Exotic Animals of the University of Veterinary Medicine and Pharmacy. Adult trematodes were isolated from the pharynx of the eagle after oesophagoscopy. The morphological and molecular identification of the flukes confirmed a trematode Cathaemasia hians (Cathaemasiidae), the obligate parasite of black storks (Ciconia nigra) and white storks (Ciconia ciconia). This finding represents the first documented case of C. hians in new bird host species and indicates broader spectrum of definitive hosts of the fluke.

“…In contrast, Black storks feed on frogs, salamanders, amphibians, fi sh and molluscs, which live in the swamps and slow-fl owing waters (Merino et al, 2001;Liptovszky et al, 2012;Zhytova & Korol, 2012). The life cycle of C. hians (Rudolphi, 1809) involves molluscs of the family Planorbidae and Lymnaeidae, representing the fi rst intermediate hosts, however in Central Europe cercaria of C. hians have been confi rmed only in the great pond snail Lymnaea stagnalis and the ram's horn snail Planorbis planorbis in Poland, the Czech Republic and Ukraine (Grabda-Kazubska et al, 1990;Faltýnková et al, 2008;Zhytova & Korol, 2012). Flukes can elicit irreversible altera tions in the tissues of digestive system of defi nitive hosts thus lowering the fi tness of the birds.…”

Cathaemasia hians infection in Black stork in Slovakia: morphological and histopathological study

et al. 2015

SummaryCathaemasia hians is an obligate trematode parasite of Black storks that are on the List of protected birds in Europe. In the present study, adult trematodes were isolated from the Black stork post mortem and morphological study revealed C. hians species. In total, 10 worms were found in the oesophagus and the ventriculus of the bird. Histopathological examination of the tissue samples of oesophagus, proventriculus and ventriculus was performed on paraffi n sections using a set of staining procedures. The sporadic lesions were seen in the tela submucosa of oesophagus containing connective tissue mast cells, eosinophils and heterophils and some foci were surrounded by the fi brous tissue. In addition, a few infl ammatory nodules had larval-like material inside, probably being of the same species. There were no visible morphological alterations in the epithelial layer of lamina propria mucosae of proventriculus, rich in goblet cells as well as in the tela submucosa. Majority of trematodes were localized in the ventriculus, where the lamina propria mucosae was damaged or disrupted sporadically. In these sites, in the tela submucosa, a various food-originated inorganic/organic material and eggs of C. hians were deposited, stimulating a weak infl ammatory response. Nodules containing larvae were not observed in any of ventriculus tissue layers. This study demonstrated, for the fi rst time, infection with adults of C. hians trematode in the Black stork nesting in Slovakia. The presence of larvae and eggs in the tissues of the upper gastrointestinal tract of bird was associated with mild infl ammatory response but feeding behaviour of adult worms in the ventriculus probably contributed to the enhanced susceptibility of the lamina propria mucosae to mechanical damage by inorganic material. Although larval stages have not yet been documented in the intermediate hosts in Slovakia, our report indicates that the life cycle of C. hians might occur in Central Europe.
