investigations of intermediate host specificity help to elucidate the taxonomic status of trichobilharzia ocellata (digenea: schistosomatidae).the avian schistosomatid trichobilharzia ocellata plays an important role as causative agent of cercarial dermatitis of humans in europe. in order to improve the taxonomic knowledge on this parasite, studies of miracidial chemo-orientation as well as experimental infections of different snail species were conducted using strains of t. ocellata and t. franki. both schistosomes exhibited a high intermediate host specificity. the miracidia clearly preferred the scw (snail-conditioned water) of the ...200111467784
new cryptic species of the 'revolutum' group of echinostoma (digenea: echinostomatidae) revealed by molecular and morphological data.the digenean species of echinostoma (echinostomatidae) with 37 collar spines that comprise the so-called 'revolutum' species complex, qualify as cryptic due to the interspecific homogeneity of characters used to differentiate species. only five species were considered valid in the most recent revision of the group but recent molecular studies have demonstrated a higher diversity within the group. in a study of the digeneans parasitising molluscs in central and northern europe we found that radix ...201323497579
integrative taxonomic approach to the cryptic diversity of diplostomum spp. in lymnaeid snails from europe with a focus on the 'diplostomum mergi' species complex.recent molecular studies have discovered substantial unrecognised diversity within the genus diplostomum in fish populations in europe and north america including three species complexes. however, data from the first intermediate host populations are virtually lacking. this study addresses the application of an integrative taxonomic approach to the cryptic species diversity of diplostomum spp. in natural lymnaeid snail populations in europe with a focus on the 'd. mergi' species complex.201526036245
equations for describing growth of the schistosome host snail biomphalaria glabrata.biomphalaria glabrata and stagnicola palustris were raised in aquaria under crowded and uncrowded conditions. measurements of greatest shell diameter were taken at regular intervals. von bertalanffy and logistic growth curves were fitted by least squares and maximum likelihood methods. the resulting parameter estimates produced better fits for the logistic equation than for the von bertalanffy equation.19846737172
molecular identification of first putative aquaporins in snails.aquaporins (aqps), also known as water channel proteins, are members of a large protein family termed major intrinsic proteins (mip). the mammalian aqps have been most comprehensively described, while knowledge about aqps in invertebrates is limited mainly to insects. not a single aqp protein has been described in snails to date. consequently, we decided to search for the proteins in gastropod representatives, namely lymnaea stagnalis, catascopia occulta, and stagnicola palustris (mollusca; gast ...201424445747
