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

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

Ultrastructure of the Schistosoma mansoni cercaria

Micron, 2002
The cercaria of the schistosome parasite is a short-lived, free-swimming larval stage that is infective for the mammalian, definitive host. This atlas describes the ultrastructure of the cells that comprise the cercaria of Schistosoma mansoni, a leading causative agent of human schistosomiasis.

The Maintenance of Schistosoma Mansoni in the Laboratory

Journal of Infectious Diseases, 1956
maintained in this laboratory since 1950. Cercariae of S. mansoni in large numbers were required for our studies of their enzymatic activity (Lewert and Lee, 1954 and 1956) and, of necessity, simple and effective methods of maintaining a large colony of Australorbis glabratus were developed.

The Ultrastructure of the Schistosoma mansoni Egg

The American Journal of Tropical Medicine and Hygiene, 1988
Helminth eggs have resisted analysis by electron microscopy because fixatives, dehydrating agents, and embedding media penetrate these eggs poorly. Slam-freezing at liquid nitrogen temperature followed by freeze-substitution and Spurr's medium embedment provides preservation of the internal structure of the Schistosoma mansoni egg shell, developing ...

Ferrocenyl, Ruthenocenyl, and Benzyl Oxamniquine Derivatives with Cross-Species Activity against Schistosoma mansoni and Schistosoma haematobium.

ACS Infectious Diseases, 2017
Schistosomiasis is a parasitic disease that affects more than 250 million people annually, mostly children in poor, tropical, rural areas. Only one treatment (praziquantel) is available, putting control efforts at risk should resistance occur. In pursuit

Infarction of testicle and schistosoma mansoni

Urology, 1975
The first case of clinical involvement and infarction of the testes caused the Schistosoma mansoni is reported. Although a rare rhenomenon, one must consider this in the differential diagnosis of testicular disease in patients who have resided in endemic areas of S. mansoni.

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.

Labeling of the Schistosoma mansoni Tegument

2020
Schistosomes are deadly pathogens responsible for the neglected tropical disease schistosomiasis. The parasite's virulence is aided by a skin-like tissue called the tegument. The study of the tegument is hampered by a lack of tools suitable for visualizing the tissue.
