| systematic position and phylogenetic relationships of the family omphalometridae (digenea, plagiorchiida) inferred from partial lsrdna sequences. | the phylogenetic relationships and systematic position of the digenean genus omphalometra looss, 1899 and several other closely related genera, have always been controversial and opinions of different authors on the systematic rank and content of this group have varied greatly. molecular analysis based on the partial sequences of the large subunit ribosomal dna gene of representatives of the genera omphalometra, rubenstrema and neoglyphe as well as previously published sequences of members of fi ... | 2001 | 11165275 |
| the neuro-muscular system in continuously swimming cercariae from belarus. i xiphidiocercariae. | the neuromuscular system (nms) in cercariae of neoastiotrema trituri, plagiorchis elegans, omphalometra flexuosa, skrjabinoeces similis and prosthogonimus ovatus was studied with immunocytochemical methods and confocal scanning laser microscopy. the patterns of f-actin in the musculature, 5-ht immunoreactive (ir), fmrfamide-ir neuronal elements and α-tubulin-ir sensory receptors were investigated, and they were found to be rather similar in all the cercariae studied. four species have seven pair ... | 2012 | 22868890 |
