Internal Defenses of the Snail Biomphalaria glabrata
Journal of Invertebrate Pathology, 1999Injection 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.

5-Hydroxytryptamine and Dopamine in Biomphalaria glabrata
The Journal of Parasitology, 19745-hydroxytryptamine (5-HT) and dopamine (DA) have been isolated and identified in the tissues of the snail, Biomphalaria glabrata. The brain contained approximately 15 tAg, the cephalopedal region 2 ,ug, and the mantle region 1 jug of 5-HT per gram of fresh weight. The concentrations of DA in the brain and the cephalopedal region were of the same order

Biosystematics of Biomphalaria spp. with an Emphasis on Biomphalaria glabrata
2010We 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.

Morphological characterization of hemocytes from Biomphalaria glabrata and Biomphalaria straminea
Micron, 2012Biomphalaria 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, 19771. 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, 1975Biomphalaria 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, 1982The 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, 2005The 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, 2000Metabolism 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.

Amebocytic Accumulations in Biomphalaria Glabrata: Fine Structure
Developmental & Comparative Immunology, 1982Internal pathologic conditions in four stocks of Biomphalaria glabrata involve amebocytes. Most snails exhibiting these conditions are also nonsusceptible to infection with Schistosoma mansoni. Fine structure studies reveal that periaortic and atrial amebocytic accumulations show two responses that involve heart tissue: a generalized response in which ...
