Schistosoma mansoni Infections in Neonatal Biomphalaria glabrata Snails

The Journal of Parasitology, 1992
In areas endemic for schistosomiasis, the population dynamics of the snail intermediate hosts have a direct effect on parasite transmission. The present study focused on the potential for neonatal Biomphalaria glabrata snails to become infected with Schistosoma mansoni and to produce cercariae under various conditions. It was found that snails as small

Superinfection of Biomphalaria glabrata with Schistosoma mansoni

The Journal of Parasitology, 1975
Biomphalaria glabrata 2 to 12 mm in diameter were exposed to 1 miracidium of Schistosoma mansoni and after 15, 30, or 60 days were reexposed to the homologous strain. The criterion of superinfection was the subsequent escape of cercariae of both sexes.

Schistosoma mansoni Modulation of Phagocytosis in Biomphalaria glabrata

The Journal of Parasitology, 1990
Both short-term (3 hr) exposure of Biomphalaria glabrata snails (M-line and 13-16-R1) to Schistosoma mansoni (PR1) miracidia and in vitro incubation of parasite sporocysts with host hemolymph components altered host phagocytic ability. Hemocytes obtained from susceptible (M-line) snails that had been exposed to parasite miracidia for 3 hr showed ...

Biosystematics of Biomphalaria spp. with an Emphasis on Biomphalaria glabrata

2010
We review the characters and approaches that have been used to build the systematics of the genus Biomphalaria with special emphasis on Biomphalaria glabrata. Shell characters can be used to distinguish groups of species, but are of limited use for separating closely allied species because of wide ecophenotypic variation.

Adaptation of Biomphalaria glabrata to foreign invaders

Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 2009
In their natural environment, organisms are constantly fighting against multiple invaders such as viruses, bacteria, fungi, or hel- minths thanks to one of the most remarkable evolutionary adaptation that is immunity. Aquatic molluscs are particularly exposed to tre- matode infections since the 6000 known trematode species use molluscs as first ...

Genetic studies on amebocytic accumulations in Biomphalaria glabrata

Journal of Invertebrate Pathology, 1980
Abstract Four types of spontaneous amebocytic accumulations have been reported in Biomphalaria glabrata . Results of crosses involving snails with and without accumulations suggest that the formation of the amebocytic accumulations is controlled by a polygenic system of inherited factors.

Edema-horn, an abnormal mutant of Biomphalaria glabrata

Journal of Invertebrate Pathology, 1980
Abstract An abnormal condition is reported in the pulmonate gastropod Biomphalaria glabrata involving body edema and flaring of the shell aperture. Selection and selfing of isolated snails suggested this character is inherited. Crossing experiments indicated the character is inherited as a simple recessive.

Bulbous head growths of Biomphalaria glabrata: Genetic studies

Journal of Invertebrate Pathology, 1973
Abstract Two different types of abnormal growths, median head bulb and bulbous tentacle, are described from the mollusk Biomphalaria glabrata . Both bulbous growths are rythmically contractile. Bulbous tentacle is typically unilateral. Both abnormalities are determined before emergence of the snails from the egg capsues.
