Project description:Differential transcriptomic responses of Biomphalaria glabrata (Gastropoda, Mollusca) to bacteria and metazoan parasites Schistosoma mansoni and Echinostoma paraensei (Digenea, Platyhelminthes). Transcriptional profiling of Biomphalaria glabrata comparing control uninfected M-line B. glabrata with five experimental groups. The experimental groups are: wounded but not infected M-line, Escherichia coli infected, Micrococcus luteus infected, Echinostoma paraensei infected and Schistosoma mansoni infected at 12 hours time point post infection. Seven groups of samples: two controls, wounded, two bacterial- and two trematode-infected B. glabrata were analyzed in triplicate, using universal RNA reference.

Project description:Time series analysis of the transcriptional responses of Biomphalaria glabrata throughout the course of intramolluscan development of Schistosoma mansoni and Echinostoma paraensei. Time series transcriptional profiling of Biompharlia glabrata comparing control uninfected M line B.glabrata with trematdoe infected groups. The experimental groups are: Echinostoma paraensei infected and Schistoma mansoni infected at 12 hours(0.5day), 1 day, 2 days, 4 days, 8 days, 16 days adn 32 days post infection. Samples: control and two trematode infected B.glabrata in a time series: 0.5, 1, 2, 4, 8, 16 and 32 days post exposure were analyzed in triplicate Stress and immune response

Project description:During its life cycle, the helminth parasite Schistosoma mansoni uses the freshwater snail Biomphalaria glabrata as an intermediate host to reproduce asexually generating cercariae for infection of the human definitive host. Following invasion of the snail, the parasite develops from a miracidium to a mother sporocyst and releases excretory secretory products (ESPs) that likely influence the outcome of host infection. To better understand molecular interactions between these ESPs and the host snail defence system, we determined gene expression profiles of haemocytes from S. mansoni resistant or -susceptible strains of B. glabrata exposed in vitro to S. mansoni ESPs (20ug/ml) for 1 h, using a 5K B. glabrata cDNA microarray.

Project description:Schistosomiasis is one of the most socioeconomically harmful neglected tropical diseases in the world. It occurs following infection from parasites of the Schistosoma genus, such as Schistosoma mansoni, which must transition within a molluscan and mammalian host to survive. Previous chemical analyses of schistosome-molluscan interactions indicate that schistosomes orientate towards potential hosts partially through chemosensation, displaying a preference for naïve (uninfected) hosts. Recent advances in proteomic techniques enable sophisticated comparative analyses between infected and naïve snail host proteins. This study aimed to compare the snail-conditioned water (SCW) released by F1 resistant, infected and naïve Biomphalaria glabrata to identify potential attractants and deterrents.
