The 18S rDNA sequences of the six most common European Lymnaeidae species (Mollusca:Gastropoda:Basommatophora) have been obtained by direct PCR cycle sequencing and silver staining methods. The sequence alignment and secondary structures of the 18S rRNA gene of Lymnaea stagnalis, L. auricularia, L. peregra, L. palustris, L. glabra, and L. truncatula are analyzed. This gene proves to be a good m...

objective: lymnaea palustris was previously found in mazandaran province but there was not any report about its parasitologic aspects. this study was conducted to finding ecological and parasitological aspects of snail in mazandaran province, north of iran. materials and methods: in this descriptive study, more than 181 locations, were checked, in 36 locations, colonies of the snail were found...

background: human echinostomiasis is an intestinal disease caused by the members of family echinostomatidae parasites. the aim of present research was to identify echinos­tomatidae cercariae emitted by lymnaea palustris snails from mazandaran province in the north of iran based on the morphological and morphometrical charac­teristics of the different stages of experimental parasite life cycle. ...

The problem of the effects of isolation in relation to the establishment of subspecies and local races has been studied by many workers since the time of DARWIN and WALLACE, but in most instances it has been attacked only from the standpoint of geographical speciation. Little attention has been paid to the relationship existing between the type of variation in any one circumscribed locality, an...

Aquatic snails were collected at 148 sites from various wetland habitats in central Minnesota between May and September, 1988. These data were used to determine the distribution, environmental preference and parasite-intermediate host relationships of lymnaeid snails found within the study area. Lymnaeids generally preferred still water of near neutral pH with a small particle size substrate. H...

Transmission patterns of Fasciola hepatica were investigated on beef cattle (n=3) and sheep (n=3) farms in Sweden between 2011 and 2012. The dynamics of fluke infection, particularly estimated time of infection, were screened each grazing season by ELISA detection of antibodies in lambs (n=94) and first grazing season calves (n=61). Colostral transfer of F. hepatica antibodies from seropositive...
