The influence of stream geology on the distribution of the bilharzia host snails,Biomphalaria pfeifferiandBulinus (Physopsis)sp

Annals of Tropical Medicine & Parasitology, 1975
The Gladdespruit and Komati River surveys have shown that similar environmental conditions have developed where the watercourses flowed over particular rock types. In these watercourses a potentially useful association was found between the occurrence of permanent, lentic habitats produced by the weathering of bedrock with a hardness above 5 in Mohs ...

The symbiont Capsaspora owczarzaki, nov. gen. nov. sp., isolated from three strains of the pulmonate snail Biomphalaria glabrata is related to members of the Mesomycetozoea

International Journal for Parasitology, 2002
While investigating the resistance of some strains of Biomphalaria glabrata to infection with Schistosoma mansoni, a unicellular eukaryotic symbiont was noted in the snail haemolymph. It was similar in appearance to Nuclearia sp. reported from B. glabrata.

[Experimental study of the life cycle of Echinostoma togoensis n. sp., a larval parasite of Biomphalaria pfeifferi in Togo (author's transl)].

Annales de parasitologie humaine et comparee, 1982
The adult and larval stages of Echinostoma togoensis are described. E. togoensis develops into rediae in the ovotestis of Biomphalaria pfeifferi which is totally sterilized. The metacercariae were recovered either in the pericardial cavity of several aquatic Pulmonata, or in the kidney of amphibian tadpoles. The adult was experimentally obtained in the

[Life cycle of Clinostomum golvani n. sp. (Trematoda : Clinostomidae) a larval parasite of Biomphalaria glabrata, the snail vector of Schistosoma mansoni in Guadeloupe (author's transl)].

Annales de parasitologie humaine et comparee, 1981
The life cycle of a new species of Clinostomidae, Clinostomum golvani, described in Guadeloupe (French West Indies). The first intermediate host is the snail vector of Schistosoma mansoni in this island, Biomphalaria glabrata, which can be sterilized by this parasite. Poecilia reticulata (guppy) serves as the second intermediate host.

Immunodiffusion studies on Schistosoma mansoni and its intermediate host stage specific antigens. 3. Immunoelectrophoresis cross-reactions between S. mansoni stages and Biomphalaria sp. hepato-pancreas antigens.

Egyptian journal of bilharziasis, 1978
IMMUNOELECTROPHORESIS was applied for cross-wise checking of the different stages in the life cycle of schistosoma mansoni with extracts of hepato-pancreas from its intermediate host snails Biomphalaria glabrata and Biomphalaria alexandrina. Only few fractions were common to non infected snail organ and parasite development stage, while more ...
