Schistosoma mansoni and other Schistosoma sp. are multicellular parasitic helminths (worms) that infect humans and mammals worldwide. Infection by these parasites, which results in developmental maturation and sexual differentiation of the worms over a period of 5-6 weeks, induces antibodies to glycan antigens expressed in surface and secreted glycoproteins and glycolipids. There is growing int...

Abstract Schistosomes are parasitic flatworms causing one of the most prevalent infectious diseases from which millions people currently suffering. These parasites have high fecundity and their eggs both transmissible agents cause infection-associated pathology. Given its biomedical significance, schistosome germline has been a research focus for more than century. Nonetheless, molecular mechan...

Digenean trematodes are common and abundant in aquatic habitats and their free-living larvae, the cercariae, have recently been recognized as important components of ecosystems in terms of comprising a significant proportion of biomass and in having a potentially strong influence on food web dynamics. One strategy to enhance their transmission success is to produce high numbers of cercariae whi...

Bird schistosomes parasitize mammals as non-specific hosts. Neurotropic Trichobilharzia regenti migrates extravasally via nervous tissue in experimentally infected mice. The majority of successfully penetrated larvae remain in the skin; the rest migrate through peripheral nerves to the spinal cord and brain. The potential of schistosomula to leave the skin and enter the central nervous system v...

roteases, including cysteine-, serine-, threonine-, aspartate-, and metallo-proteases, are a group of enzymes that have the catalytic ability to hydrolyze or digest peptide bonds of proteins. Proteases play important roles in host invasion, hemoglobin degradation, transformation and immune invasion of schistosomes. The gut cathepsin B of all schistosomes including S. japonicum, S. mansoni and S...
