Internal Defenses of the Snail Biomphalaria glabrata

Journal of Invertebrate Pathology, 1999
Injection of foreign particles (zymosan, latex beads, living bacteria) and substances (ferritine, horseradish peroxidase) in Biomphalaria glabrata induces the rapid appearance of tubular double-helical filaments in the hemolymph. This rapid induction may be due to the polymerization of precursor proteins of the hemolymph.

Morphological characterization of hemocytes from Biomphalaria glabrata and Biomphalaria straminea

Micron, 2012
Biomphalaria glabrata and Biomphalaria straminea have been identified as intermediate hosts for Schistosoma mansoni. Several studies have found two cell types in the hemolymph of B. glabrata (hyalinocytes and granulocytes). However, there are no studies describing the hemocytes of B. straminea. With the aim of further describing the hemocyte subsets in

Glycogen metabolism in the snail, Biomphalaria glabrata

Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1977
1. The distribution of glycogen in different tissues of the snail, Biomphalaria glabrata was determined; the cephalopedal region contained 15-17 mg, the mantle region 23-29 mg, the hepatopancreas 31-45 mg, and the ovotestis 50 mg of glycogen/g wet wt. 2.

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.

Further Characterization of Acquired Resistance in Biomphalaria glabrata

The Journal of Parasitology, 1982
The albino strain of Biomphalaria glabrata is capable of developing an acquired resistance to echinostomes that is relatively specific, i.e., strong against Echinostoma lindoense, challenged by the homologous species, moderate or weak against closely related E. paraensei and E.

Manganese superoxide dismutase from Biomphalaria glabrata

Journal of Invertebrate Pathology, 2005
The investigation of the response of Biomphalaria glabrata snails to Echinostoma paraensei (digenea) at 2 days post-exposure by suppression subtractive hybridization yielded a partial sequence of the anti-oxidant enzyme manganese superoxide dismutase (MnSOD). Full-length MnSOD (669nt) from M line and BS-90 strains of B.

Monoamines and their metabolites in the freshwater snail Biomphalaria glabrata

Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 2000
Metabolism of the major monoamines and their functions were studied in the freshwater snail Biomphalaria glabrata. In both juvenile and adult snails, the plasma (cell-free hemolymph) appears to act as a reservoir for most of these monoamines and their metabolites including among others, L-dopa and dopamine as major constituents.

The galactan-degrading enzymes in the snail Biomphalaria glabrata

Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1991
1. Embryonic snails incorporate from the perivitelline fluid in which they are embedded a polysaccharide, called galactan, which is composed entirely of D-, or D- and L-galactose. In this investigation the p-nitrophenyl-beta-D-galactoside degrading enzyme of Biomphalaria glabrata which was assumed to be involved in the degradation of the galactans was ...

Embryonic development of the shell in biomphalaria glabrata (Say)

The International Journal of Developmental Biology, 1991
During embryogenesis of the fresh water snail Biomphalaria glabrata (Say) (Pulmonata, Basommatophora) shell formation has been studied by light and electron microscopical techniques. The shell field invagination (SFI), the secretion of the first shell layers, the development of the shell-forming mantle edge gland and spindle formation have been ...

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 ...
