Climate change may affect the internal defense system (IDS) of freshwater snails, and as a result their capacity to transmit disease. We examined effects of short-term exposure to supra- and sub-optimal temperatures or starvation on 3 parameters of t

The anterior pericardial wall or amebocyte-producing organ (APO) is a site of hemocyte formation in the schistosome-transmitting snail Biomphalaria glabrata. Histological sections of the APOs of adult schistosome-resistant Salvador strain snails, and

Several genes have recently been shown to affect the innate resistance of laboratory strains of Biomphalaria glabrata to infection with Schistosoma mansoni, including Hsp90, the expression of which following a brief exposure to elevated temperature c

Albino strains of Biomphalaria glabrata that are compatible with Schistosoma mansoni are commonly used to investigate snail-schistosome interactions, but whether they are all equally compatible is not known. In this study, compatibility with the Nava

Lipopolysaccharide (LPS) is a pathogen associated molecular pattern (PAMP) to which the internal defense system (IDS) of both vertebrates and invertebrates responds. We measured the mitotic response of the hematopoietic tissue of the schistosome-tran

The laboratory BS-90 strain of the freshwater pulmonate snail Biomphalaria glabrata, progeny of snails collected from Salvador, Brazil, is resistant to infection with Schistosoma mansoni as juveniles or adults, which rapidly kill primary sporocysts w

Although Schistosoma mansoni occurs mainly in the tropics, where intense levels of solar radiation are present, the impact of ultraviolet (UV) light on schistosome transmission is not known. The purpose of this study was to investigate potential effe

Heart xenografts from the pulmonate snail Helisoma trivolvis survive in Biomphalaria glabrata, whereas xenografts from most other pulmonate snail genera are rejected within 3 to 15 days. To test whether xenografts from snails closely related to H. tr

Adult Salvador (schistosome-resistant) strain Biomphalaria glabrata snails were injected with 5 μl of 10 mg/ml solutions of the sulfated polysaccharides λ carageenan, dextran sulfate, fucoidan, and heparin, the nonsulfated polysaccharide laminarin,

We examined a potential mechanism for adoptively transferred resistance against Schistosoma mansoni in schistosome-susceptible snails receiving allografts of the hematopoietic amebocyte-producing organ (APO) from a schistosome-resistant strain of Bio
