Immunoregulation by Schistosoma mansoni
Immunopharmacology, 1981Schistosoma mansoni is known to release an inhibitory factor of lymphocyte proliferation elicited in vitro. The effect of this dialyzable schistosome incubation product (DSIP) was tested in vivo on different aspects of the cell-mediated immune response.

Phosphomonoesterases of Schistosoma mansoni
Experimental Parasitology, 1963Abstract Extracts of adult Schistosoma mansoni were shown to contain high concentrations of both acid and alkaline phosphomonoesterases. In vitro investigations of the enzymes were made with regard to pH optima in different buffers, rates of hydrolysis of and affinities for several phosphomonoesters, stability, and response to activators and ...

The Integument of Schistosoma Mansoni
The American Journal of Tropical Medicine and Hygiene, 1969Abstract The structure of the integument of Schistosoma mansoni is described by histochemical and electron-microscopical study, and the effects of incubating adult schistosomes in buffered saline, thyoglycollic acid, horse-radish peroxidase, normal and immune serum are described.

Carbohydrate Metabolism of Schistosoma Mansoni. [PDF]
Journal of General Physiology, 1950 1. Schistosoma mansoni utilizes in 1 hour an amount of glucose equivalent to one-sixth to one-fifth of its dry weight. Over 80 per cent of the metabolized glucose is converted to lactic acid by this organism. 2. The rates of glucose utilization and of lactic acid production by S.

Is Schistosoma mansoni Replacing Schistosoma haematobium in the Fayoum?
The American Journal of Tropical Medicine and Hygiene, 1993Schistosoma mansoni is progressively replacing S. haematobium along the Nile River in Egypt. This change has occurred in the past 15-20 years following construction of the Aswan High Dam in the 1960s. The cause is a shift in relative abundance of the snail vectors Biomphalaria alexandrina and Bulinus truncatus.

Schistosoma mansoni and Schistosoma haematobium: Differences in development
Experimental Parasitology, 1981Abstract Growth and maturation of the Puerto Rico strain of Schistosoma mansoni in mice and the Ghana strain of Schistosoma haematobium in hamsters were compared beginning 19 days after infection. In S. mansoni, optimum development was determined, with copulation first observed on Day 25, egg shell protein formation observed on Day 28, and ...

Underestimation of Schistosoma mansoni prevalences
Parasitology Today, 1992Field methods used for detecting Schistosoma mansoni infection miss a certain proportion of the infections. Prevalences of infection appear to be far under-estimated by faecal screening, with important consequences for control and research. Sake de Vlos and Bruno Gryseels investigate how the number of undetected infections can be statistically inferred
