Cryopreservation of Schistosoma mansoni Sporocysts
The Journal of Parasitology, 1984Studies 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.

Schistosoma mansoni: Cryopreservation of schistosomules
Experimental Parasitology, 1979Abstract 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 ...

Occurrence of an agglutinin in Schistosoma mansoni
International Journal for Parasitology, 1976Abstract A membrane-associated component found in Schistosoma mansoni agglutinates untreated mouse and rat erythrocytes and seems to be a host-independent worm membrane receptor. Its possible role in the host-parasite adaptation mechanism is discussed.

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 ...

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: Cercaria to Schistosomule
1974Publisher Summary This chapter discusses the cercaria-schistosomule development of Sclzistosoma mansoni. The characteristic features of embryonic and emerged cercariae and of schistosomules are closely compared and contrasted in respect of tegument, glycocalyx, and tegumentary spines, sensory papillae, nerves and muscle, secretory cells, digestive ...

Mating of Schistosoma mansoni in Vitro
Experimental Parasitology, 1969Abstract 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.
