BACKGROUND New chemotherapeutic agents against Schistosoma mansoni, an etiological agent of human schistosomiasis, are a priority due to the emerging drug resistance and the inability of current drug treatments to prevent reinfection. Proteases have been under scrutiny as targets of immunological or chemotherapeutic anti-Schistosoma agents because of their(More)
The clumping parameter related to the distribution of schistosome parasites is obtained by fitting a negative binomial distribution to data collected from patients in a village in Brazil; the natural uninfected and parasite-induced snail host mortality rates are obtained from laboratory data. These values are used in a schistosomiasis model proposed earlier(More)
Transposable elements (TEs) are mobile genes with an inherent ability to move within and among genomes. Theory predicts that TEs proliferate extensively during physiological stress due to the breakdown of TE repression systems. We tested this hypothesis in Schistosoma mansoni, a widespread trematode parasite that causes the human disease schistosomiasis.(More)
Parasites can profoundly impact their hosts and are responsible for a plethora of debilitating diseases. To identify global changes in host gene expression related to parasite infection, we sequenced, assembled, and annotated the liver transcriptomes of Balb/cj mice infected with the trematode parasite Schistosoma mansoni and compared the results to(More)
Parasite genetic variation has been used to delineate and enumerate species, describe host–par-asite associations, and observe the distribution of lineages among hosts and throughout the environment. Mechanisms or pathways inferred by these studies have often been carried forward in a predictive manner to inform assumptions about the organism's biology, its(More)
