Abstract The hatchability of Schistosoma mansoni eggs exposed to ultraviolet (UV) radiation and the activity of die hatched miracidia were examined. Hatchability decreased with die increasing exposure to irradiation. The difference in hatchability of eggs irradiated for 15 and 30 minutes were highly significant (P < 0.01. da = 3.07 and 3.24) compared with hatchability of the non-irradiated eggs. The mean motility rates of the hatched m iracidia were found to be radiation dose-dependent. There...
Abstract Merozoite surface protein-119 (MSP-119) specific antibodies which include processing inhibitory, blocking and neutral antibodies have been identified in individuals exposed to Plasmodium falciparum. Here we intend to look at the effect of single and multiple amino acid substitutions ofMSP-119 on the recognition by polyclonal antibodies from children living in Igbo-Ora, Nigeria. This would provide us with information on the possibility of eliciting mainly processing inhibitory antibod...
