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

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

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

Improving the success of external cephalic version (ECV) for breech presentation may help avoid some cesarean deliveries. The results of randomized trials comparing the success of ECV with neuraxial analgesia compared to control are inconsistent. We

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

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

Hearts of the snails Physa virgata and Biomphalaria glabrata were implanted into the hemocoel of B. glabrata. Implants either were microencapsulated in 2.5% agarose or were unencapsulated. Unencapsulated xenografts from P. virgata underwent complete

Helisoma spp. snails are not susceptible to infection with miracidia of Schistosoma mansoni because the miracidia do not penetrate them. However, in view of the phylogenetic proximity and histocompatibility between Helisoma spp. and the normal interm
