Abstract Biomphalaria snails are instrumental in transmission of the human blood fluke Schistosoma mansoni . With World Health Organization's goal to eliminate schistosomiasis as a global health problem by 2025, there is now renewed emphasis on snail control. Here, we characterize genome glabrata, lophotrochozoan protostome, and provide timely important information biology. We describe aspects phero-perception, stress responses, immune function regulation gene expression that support...
Three hypotheses concerning potential genetic benefits of female multiple mating behaviour are evaluated for the common shrew. In a high-density population, many successful copulations took place between individuals estimated to be close relatives (e.g. full or half siblings). Juveniles resulting from such matings tended relatively small at weaning, and were generally less likely survive sexual maturity than more outbred individuals. Multiple paternity was discovered in eight nine litters...
Restriction analysis had revealed only Mus domesticus mtDNA in house mouse populations northern Denmark, Sweden, and Finland, where the nuclear genomes are musculus. The goals of present study were to (1) test proposal that these Scandinavian musculus mice arose by a series founder island-hopping events from one or few near domesticus-musculus hybrid zone on East Holstein Peninsula Germany (2) see whether more than two types detected restriction existed among populations. Sequences 1...
Abstract Highly migratory, cosmopolitan oceanic sharks often exhibit complex movement patterns influenced by ontogeny, reproduction, and feeding. These elusive species are particularly challenging to population genetic studies, as representative samples suitable for inferring structure difficult obtain. Our study provides insights into the one of most abundant wide‐ranging shark species, blue Prionace glauca, sampling least mobile component populations, i.e., young‐of‐year small juveniles...
The west European subspecies of house mouse (Mus musculus domesticus) has gained much its current widespread distribution through commensalism with humans. This means that the phylogeography M. m. domesticus should reflect patterns human movements. We studied restriction fragment length polymorphism (RFLP) and DNA sequence variations in mitochondrial (mt) throughout British Isles (328 mice from 105 localities, including previously published data). There is a major mtDNA lineage revealed by...
The outcome of infection in the host snail Biomphalaria glabrata with digenean parasite Schistosoma mansoni is determined by initial molecular interplay occurring between them. mechanisms which schistosomes evade immune recognition to ensure survival are not fully understood, but one possibility that internal defence system manipulated schistosome enabling establish infection. This study provides novel insights into nature resistance and susceptibility B. at transcriptomic level...
Nuclear receptors (NRs) are transcription regulators involved in an array of diverse physiological functions including key roles endocrine and metabolic function. The aim this study was to identify nuclear the fully sequenced genome gastropod snail, Biomphalaria glabrata, intermediate host for Schistosoma mansoni compare these known vertebrate NRs, with a view assessing snail's potential as invertebrate model organism function, both prospective new test elucidate fundamental genetic...

Abstract Background Biomphalaria glabrata is an intermediate snail host for Schistosoma mansoni , one of the important schistosomes infecting man. B. glabrata/S. provides a useful model system investigating intimate interactions between and parasite. Examining differential gene expression S. -exposed schistosome-resistant susceptible lines will identify genes pathways that may be involved in defences. Results We have developed 2053 element cDNA microarray containing clones from ORESTES (Open...
Beta-N-Acetylglucosaminidase has been purified from an acetone extract of Aspergillus niger. The protein a Mr = 149,000. It contains neither Mn2+, Zn2+, nor cysteine and exhibits no cation requirement for activity. Isoelectric focusing separates two isozymes; the major isoenzyme pI 4.4. Both isozymes exhibit beta-N-acetylgalactosaminidase beta-glucosidase, as well glucosaminidase mechanism action this enzyme studied in detail using variety substrate structure/activity kinetic experiments....
Male common shrews (Sorex araneus) adopt two discrete mating tactics. The most successful males, in terms of number offspring fathered, are those that establish large overlapping home ranges areas high female density early the breeding season. An alternative, less tactic is to travel long distances search opportunities. This study an investigation correlates reproductive success for males adopting these different Reproductive under natural conditions was assessed using DNA fingerprinting,...
Trematode parasites share an intimate relationship with their gastropod intermediate hosts, which act as the vehicle for development and transmission. They represent enormous economic medical burden in developing countries, stimulating much study of snail–trematode interactions. Laboratory-maintained systems vitro cell cultures are being used to investigate molecular dialogue between host parasite. These dynamic finely balanced antagonistic relationships, strongly influence physiology host,...
Biomphalaria glabrata is the major intermediate snail host for Schistosoma mansoni, one of important schistosomes infecting man. Much remains to be discovered concerning specific molecules mediating defence events in these hosts, triggered by invading schistosomes. An expressed sequence tag (EST) gene discovery strategy known as ORESTES has been employed identify transcripts that might involved snail–schistosome interactions order examine expression patterns infected B. glabrata. Over 3930...
Population genetic perturbations of intermediate hosts, often a consequence human pressure on environmental resources, can precipitate unexpectedly severe disease outbreaks. Such disturbances are set to become increasingly common following range changes concomitant with climate shifts, dwindling natural resources and major infrastructure such as hydroprojects. Construction the Diama dam in Senegal River Basin (SRB) reduced river salinity, enabling freshwater snail host Biomphalaria pfeifferi...
The provenance of white sharks ( Carcharodon carcharias ) in the Mediterranean is both a conundrum and an important conservation issue. Considering this species's propensity for natal philopatry, any evidence that stock has little or no contemporary immigration from Atlantic would suggest it extraordinarily vulnerable. To address issue we sequenced mitochondrial control region four rare sharks. Unexpectedly, juvenile sequences were identical although collected at different locations times,...
Estimating the demographic parameters of contemporary populations is essential to success elasmobranch conservation programmes, and understanding their recent evolutionary history. For benthic elasmobranchs such as skates, traditional fisheries-independent approaches are often unsuitable data may be subject various sources bias, whilst low recapture rates can render mark-recapture programmes ineffectual. Close-kin (CKMR), a novel modelling approach based on genetic identification close...
