The two under-sampled presumably rare species, Echinostoma sp. Perhaps the most important result of our study is that the integration of echionstoma and molecular data from both experimental and wildlife infections clarified the status of E.

Recent advances in the biology of Echinostoma species in the ‘revolutum’ group. The life history of Echinostoma paraensei sp. Tkach V, Pawlowski J. Laboratory Diagnosis Laboratory Diagnosis Microscopic identification of eggs in the stool.

The occurrence and identification of Echinostoma revolutum from North American Lymnaea elodes snails. December 28, Page last updated: The head collar had a total edhinostoma 37 collar spines arranged in 2 alternating rows, including 5 corner spines on each side. Results Infections in natural host populations The large-scale screening of natural snail populations in Europe revealed infections with five Echinostoma spp.

The best-fitting models of nucleotide substitution were estimated prior to BI analyses with jModelTest 2. Guindon S, Gascuel O.

Phylogeny-based species delimitation Both NJ and BI analyses resulted in consensus trees with similar topologies. Echinostomatidae on the basis of experimental completion of its life-cycle. Genetic characterization of Echinostoma revolutum and Echinoparyphium recurvatum Trematoda: D, Detwiler et al. The provenance of this isolate is not annotated in GenBank but is clearly identified i.

The head collar of the adult was distinct, bearing 37 collar spines arranged in 2 alternating rows, including 5 corner spines on each side. The minima for sequence divergence 0. There was a taxonomic problem in identifying our specimens because of the complexity in wchinostoma systematics of collar-spined echinostomes, the so-called ‘ revolutum ‘ group [ 89 ]. Cercariae were examined live and identified using the data from the relevant primary sources e.

The day old adult flukes were elongated, ventrally curved, and 5. Adults of Echinostoma echonostoma. Sequencing of isolates from wild mammalian hosts within Europe may contribute to resolving the natural definitive hosts in the life-cycles of E. Contribution to the distribution and the life history of Echinostoma revolutum in Central Europe.

Find articles by Byoung-Kuk Na. This gap in our knowledge was addressed in the present study through an integration of morphological and molecular approaches in the investigation of a dataset with larger taxonomic and geographical coverage. The size of metacercariae may vary depending on the amount of pressure placed echinostkma the cover slip. s

SG carried out echinkstoma major part of the sequencing, performed the phylogenetic analyses and prepared the first draft of the MS. Table 1 Characteristic features of the collar-spined Echinostoma belonging to the ‘ revolutum ‘ group. Methods Sample collection More than 20, freshwater snails belonging to 16 species [ Lymnaea stagnalis L. Methods More than 20, freshwater snails belonging to 16 species were collected during — from various localities in eight countries in Europe.

New cryptic species of the ‘ revolutum ‘ group of Echinostoma Digenea: Recently, metacercariae of Echinochasmus japonicus were reported from a species of freshwater fish, Labeo rohita in Vietnam [ 24 ].

National Center for Biotechnology InformationU. Depending on the species, several animals may serve as the second intermediate host, including other snails, bivalves, fish, and tadpoles.


Echinostoma are internal digenean trematode parasites which infect the intestines and bile duct [3] of their hosts.

However, a barcode gap i. Support Echniostoma Support Center.

Identification of birds through DNA barcodes. Combining morphological and molecular evidence from different life-cycle stages, we can confidently restore the validity of this species.
