Ultraviolet B (UVB, 280-315nm) radiation is detrimental to both of larvae of the digenetic trematode Schistosoma mansoni and its snail intermediate host, Biomphalaria glabrata. We explored effects of UVB on three aspects of the interaction between host and parasite: survival of infected snails, innate susceptibility and resistance of snails to infection, and acquired resistance induced by irradiated miracidia. Snails infected for 1 week showed significantly lower survival than uninfected snails following irradiation with a range of UVB intensities. In contrast to known immunomodulatory effects in vertebrates, an effect of UVB on susceptibility or resistance of snails to infection could not be conclusively demonstrated. Finally, exposure of susceptible snails to UVB-irradiated miracidia failed to induce resistance to a subsequent challenge with nonirradiated miracidia, a result similar to that reported previously with ionizing radiation. |
