|Title:||Miracidial Attraction By Biomphalaria Tenagophila Genetically Selected For Susceptibility [atração Miraxonal Exercida Por Biomphalaria Tenagophila Selecionada Geneticamente Para O Caráter Susceptibilidade.]|
de Carvalho J.F.
|Abstract:||The attraction of Schistosoma mansoni miracidea by snails genetically selected for susceptibility to infection is considered. Miracidea were exposed to snails or to snail conditioned water in a specially devised three-chamber glass apparatus. Ten miracidea were used for each test and were deposited in the middle chamber (a passage); after 15 minutes, them in each of the number of the three chambers were recorded. In one of the chambers, chosen randomly at each trial, either snails or SCW were used. The snails and the SCW were chosen from either selected snails (highly susceptible) or unselected. The miracidea were of two groups: they came either from susceptible snails in previous generation or were of unselected traits. The results show that only snail generation has importance for the attraction: selected molluscs of susceptible traits do attract the miracidea more.|
