“…In this study, the features of our cercariae matched those displayed by the cercariae of L. nigrovenosus [19,34]; the chaetotaxy also fit with that of other representatives of Leptophallinae for which data are available (Metaleptophallus gracillimus, Macrodera longicollis (Abildgaard in Müller, 1789), Paralepoderma brumpti (Buttner, 1951), and Paralepoderma progeneticum (Buttner, 1951); details shown in Table I). Following the nomenclature proposed in [21], a chaetotaxical comparison between our cercariae and the ones mentioned above showed similarities, as noted by [34] among their cercariae. These similarities included the following: (a) the general distribution of papillae in the cephalic rings (C); (b) the AID composed of a transverse row of four median papillae, flanked on both sides by four sensilla; (c) dorsal (one PI and one PIII) and ventral (one AI, two AII, two AIII, one PI, one PII, and one PIII) body sensors, although the authors noted that sometimes PII and PIII were lacking; and (d) ventral sucker sensors (nine constant SI and a variable number of SII; zero to six papillae).…”

“…The chaetotaxic patterns of all of the above-mentioned species of leptophallids have been studied or reviewed [19,21,34]. In order to identify Leptophallus species, complementary information is needed, including a description of the entire life cycle, the chaetotaxic pattern of the cercariae, and the morphology and habitat of the adults, and molecular tools should also be used [35].…”

(1) Background: Leptophallus nigrovenosus, an esophageal parasite that primarily affects water snakes of the genus Natrix, has a known life cycle that involves snail and amphibian hosts. However, the biological aspects, chaetotaxic patterns, and pathogeny of this parasite in its hosts have not been fully elucidated. (2) Methods: Snails (Planorbarius metidjensis) were collected in Spain and examined for cercaria emergence. The larvae were used to experimentally infect Salamandra salamandra, and metacercariae were isolated. Their chaetotaxy was studied using microscopy and scanning electron microscopy. The eye histology was also examined. (3) Results: The cercariae displayed distinctive morphological characteristics. The results of this study revealed three types of ciliated sensory papillae on the cercarial teguments, suggesting an adaptation for host detection and orientation. The metacercariae isolated from subcutaneous tissues showed oval bodies covered in spines. The chaetotaxy patterns matched those of Leptophallinae species. This is the first report of the presence of L. nigrovenosus in the snail P. metidjensis. Additionally, this study detected metacercariae in the eyes of S. salamandra, emphasizing the need for further research on trematode infections in amphibian eyes. (4) Conclusions: Members of the genus Salamandra can serve as secondary intermediate hosts for L. nigrovenosus, and the presence of metacercariae in amphibian eyes may have implications for the survival and habitat management of these amphibians. Understanding this parasite’s prevalence, transmission dynamics, and impacts on host populations is crucial for conservation strategies.

“…(unpublished data from Genbank), also clustered with Psilochasmus oxyurus and Sphaeridiotrema globulus . Grabda-Kazubska et al (1991) stated that the morphological data and chaetotaxy of Echinochasmus cercaria also show that this genus appears more closely related to the Psilotrema (Odhner, 1913) and Sphaeridiotrema (Odhner, 1913) than to Echinostoma . The Psilostomidae, apart from the absence of a circumoral head-collar armed with spines, closely resemble the Echinostomatidae in their general morphology (Kostadinova 2005b).…”

“…Echinoparyphium mordwilkoi , that shows a separate position from Echinochasmus in the molecular analyses (Figs 2, 3), is restricted to the lower heterobranch Valvata piscinalis (Valvatoidea). Most of Psilostomidae species also admit for the first intermediate host a prosobranch snail (Grabda-Kazubska et al 1991), except those ones belonging to the genus Ribeiroia Travastos, 1939, which position in this family is questionable (Wilson et al 2005). The species of this genus originally have parasitized pulmonate snails.…”

The family Echinostomatidae Looss, 1899 exhibits a substantial taxonomic diversity, morphological criteria adopted by different authors have resulted in its subdivision into an impressive number of subfamilies. The status of the subfamily Echinochasminae Odhner, 1910 was changed in various classifications. Genetic characteristics and phylogenetic analysis of four Echinostomatidae species – Echinochasmus sp., Echinochasmus coaxatus Dietz, 1909, Stephanoprora pseudoechinata (Olsson, 1876) and Echinoparyphium mordwilkoi Skrjabin, 1915 were obtained to understand well enough the homogeneity of the Echinochasminae and phylogenetic relationships within the Echinostomatidae. Chromosome set and nuclear rDNA (ITS2 and 28S) sequences of parthenites of Echinochasmus sp. were studied. The karyotype of this species (2n=20, one pair of large bi-armed chromosomes and others are smaller-sized, mainly one-armed, chromosomes) differed from that previously described for two other representatives of the Echinochasminae, Echinochasmus beleocephalus (von Linstow, 1893), 2n=14, and Episthmium bursicola (Creplin, 1937), 2n=18. In phylogenetic trees based on ITS2 and 28S datasets, a well-supported subclade with Echinochasmus sp. and Stephanoprora pseudoechinata clustered with one well-supported clade together with Echinochasmus japonicus Tanabe, 1926 (data only for 28S) and Echinochasmus coaxatus. These results supported close phylogenetic relationships between Echinochasmus Dietz, 1909 and Stephanoprora Odhner, 1902. Phylogenetic analysis revealed a clear separation of related species of Echinostomatoidea restricted to prosobranch snails as first intermediate hosts, from other species of Echinostomatidae and Psilostomidae, developing in Lymnaeoidea snails as first intermediate hosts. According to the data based on rDNA phylogeny, it was supposed that evolution of parasitic flukes linked with first intermediate hosts. Digeneans parasitizing prosobranch snails showed higher dynamic of karyotype evolution provided by different chromosomal rearrangements including Robertsonian translocations and pericentric inversions than more stable karyotype of digenean worms parasitizing lymnaeoid pulmonate snails.

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.
