Quantitative study of metal present in the hemolymph of Biomphalaria glabrata (Gastropoda), infected and uninfected with Schistosoma mansoni

We conducted a preliminary study to quantify and compare two concentrations of the same metals present in the hemolymph of snail Biomphalaria glabrata. In this context, we used Induction Coupled Plasma Optical Emission Spectroscopy technique (ICP-OES), to analyze the metals in the two samples (snails infected and not infected with Schistosoma mansoni). The metals studied were: aluminum, calcium, cadmium, cobalt, chromium, copper, iron, potassium, magnesium, manganese, lead and zinc. Preliminary results showed that such metals are not involved in the defense of these organisms against the parasite, when present in their tissues.
