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 ...

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 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.

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.

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.

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.

Mating of Schistosoma mansoni in Vitro

Experimental Parasitology, 1969
Abstract Sexually mature female Schistosoma mansoni maintained in vitro without males laid eggs, a small percentage of which matured as evidenced by production of viable miracidia. The rates of oviposition and maturation of eggs were significantly increased by mating.
