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.

The snail (Biomphalaria glabrata) genome project
Trends in Parasitology, 2006In 2001, ideas for a snail genome project were discussed at the American Society of Parasitologists meeting (New Mexico) and a snail genome consortium was subsequently established (the first consortium meeting was held in 2005). A proposal for sequencing the snail genome was submitted to the National Human Genome Research Institute, and Biomphalaria ...

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

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.

Hemocytes of Biomphalaria glabrata: Factors affecting variability
Journal of Invertebrate Pathology, 1978Abstract Variability in the hemocyte number of two geographic strains of Biomphalaria glabrata was studied. In each strain a logarithmic increase in hemocyte number associated with increasing shell size was observed. A two fold increase in circulating hemocytes occurred 2 hr following the exposure of a susceptible strain of B.

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

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 ...

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.

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.

Schistosome sporocyst-killing amoebae isolated from Biomphalaria glabrata
Journal of Invertebrate Pathology, 1979Explants and swabs from the pericardium and mantle of three strains of Biomphalaria glabrata, two of them resistant to infection with Schistosoma mansoni, have yielded small amoebae, 3–5μm in diameter, in culture. These amoebae have been grown axenically through > 50 passages to date. The amoebae form cysts in dense cultures. When mixed with S. mansoni
