Comparative Effects of Hycanthone in Schistosoma Mansoni and Schistosoma Japonicum

The American Journal of Tropical Medicine and Hygiene, 1977
After in vitro hycanthone treatment followed by a 20-hour incubation in drug-free medium, Schistosoma mansoni were still resistant to labeling by a fluorescent analog of acetylcholine. S. japonicum, in contrast with the hycanthone sensitive species, showed prompt reversal of the blocking effects of hycanthone on fluorescent labeling.

Schistosoma mansoni antigen detects Schistosoma mekongi infection

Acta Tropica, 2015
Northern Cambodia and Southern Laos are highly endemic for Schistosoma mekongi. However, there is currently no immunological assay available that is specific for this form of schistosomiasis. We have validated Schistosoma mansoni antigens to detect S. mekongi-directed antibodies in human sera collected from a highly S.

Schistosoma mansoni and Schistosoma japonicum: Utilization of amino acids

International Journal for Parasitology, 1972
Abstract Bruce J. I. , Ruff M. D. , Belusko R. J. and Werner J. K. 1972. Schistosoma mansoni and Schistosoma japonicum : utilization of amino acids. International Journal for Parasitology 2: 425–430. The production of 14 CO 2 from 12 labeled amino acids by S. mansoni and S. japonicum was studied.

Molecular phylogenetic position of Schistosoma sinensium in the genus Schistosoma

Journal of Helminthology, 2001
The status of Schistosoma sinensium (samples from Thailand and from Sichuan, China) relative to other species of the genus Schistosoma was investigated using DNA sequences from the mitochondrial cytochrome c oxidase subunit 1 (CO1) gene (partial) and the nuclear ribosomal DNA second internal transcribed spacer 2 (ITS2).

Phosphomonoesterases of Schistosoma mansoni

Experimental Parasitology, 1963
Abstract 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 ...

Schistosoma mansoni and Schistosoma japonicum: Oxygen uptake by miracidia

Experimental Parasitology, 1971
Abstract The respiration of miracidia of Schistosoma mansoni and the Japanese, Philippine, and Formosan strains of S. japonicum was measured in the presence and absence of 0.001 m glucose at 1 and 5 hr after hatching. Aging increased the oxygen consumption of miracidia of S. mansoni and the Japanese and Formosan strains of S. japonicum when

The Integument of Schistosoma Mansoni

The American Journal of Tropical Medicine and Hygiene, 1969
Abstract 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.

Immunoregulation by Schistosoma mansoni

Immunopharmacology, 1981
Schistosoma 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.

A comparison of some isoenzymes of schistosoma mansoni and schistosoma haematobium

Comparative Biochemistry and Physiology, 1970
Abstract 1. 1. The electrophoretic separation is described for acid phosphatase, non-specific esterase, leucine amino peptidase, lactase, malate, α-glutamate, glucose-6-phosphate and 6-phosphogluconate dehydrogenases from adults of four populations of Schistosoma mansoni and one population of S. haematobium. 2. 2.

Production of Schistosoma haematobium and Schistosoma mansoni cercariae in Tanzania

Experimental Parasitology, 1967
Abstract Few Schistosoma haematobium cercariae emerged in darkness, but large numbers did emerge when snails were illuminated after a period in darkness, and the pattern of output was modified in response to alterations in the cycle of illumination. A rise in temperature from 23 °–30 °C stimulated the cercariae to emerge, but the effect of heat was
