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.

Acidic vesicles of Schistosoma mansoni

Parasitology Research, 2001
The fluorescent probe LysoTracker Red was used to examine for the presence of acidic vesicles in cercariae and schistosomula of Schistosoma mansoni. Acidic vesicles were widely distributed throughout the body of freshly transformed schistosomula and 24-h-old schistosomula but were absent from cercariae. The vesicles of freshly transformed schistosomula

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.

Surface antigens of Schistosoma mansoni

Molecular and Biochemical Parasitology, 1981
Abstract The outer tegument membrane of 18 h artificially prepared schistosomula of Schistosoma mansoni was labelled using the non-permeant diazonium salt of [ 125 I]iodosulphanilic acid. Eight iodinated surface proteins were identified by SDS-polyacrylamide gel electrophoresis.

Purine metabolism in Schistosoma mansoni

International Journal for Parasitology, 1972
Abstract Schistosoma mansoni has been found to have a spectrum of purine nucleotides which is similar, but not identical to mammalian cells. The principal component of this system is ATP, which is present at a level of about 5·5 × 10 −9 moles/mg worm pairs.

Cryopreservation of Schistosoma mansoni Sporocysts

The Journal of Parasitology, 1984
Studies utilizing schistosomes are greatly hindered by the unavailability of genetically uniform schistosome material. We have routinely maintained 5 male and 5 female clones of Schistosoma mansoni by serial microsurgical transplantation of sporocysts into Biomphalaria glabrata snails for 2.5 years (Cohen and Eveland, 1984, Expl Parasit.

Underestimation of Schistosoma mansoni prevalences

Parasitology Today, 1992
Field 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

Schistosoma mansoni: Cryopreservation of schistosomules

Experimental Parasitology, 1979
Abstract Conditions were established for recovery of active schistosomules of Schistosoma mansoni after cryopreservation and storage in liquid nitrogen (−196 C). Schistosomules prepared from cercariae by a shear pressure technique were subjected to a two-step cooling process consisting of a slow cooling rate to an intermediate temperature, followed ...

[Schistosoma mansoni schistosomiasis].

La Revue du praticien, 2002
Schistosomosis are parasitic diseases caused by blood flukes of the Schistosoma genus. The pathology of schistosomosis is mostly brought about by ova trapped in the tissues. In the liver, granuloma around ova eventually trigger periportal fibrosis and portal hypertension. In S.
