First record of Cathaemasia hians (Trematoda: Cathaemasiidae) in a new bird host, the Eastern Imperial Eagle (Aquila heliaca)

2023

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.
