Resumo(s)
Embora tudo leve a crer que não há diferença entre a biologia do Schisfosoma haematobium do Sul de Portugal e a mesma espécie de África, muito interessa estudar a susceptibilidade do Planorbis metidjensis do País às diversas espécies do Schistosoma.
Este estudo é feito perante o Schistosoma haematobium da Guiné Portuguesa. Importando avaliar a sua susceptibilidade ao Schistosoma mansoni, procedeu- se à esses estudos e a partir da estirpe parasitária de Moçambique.
Embora dispondo de pouco tempo e de insuficientes dados concretos, julgamos poder indicar as seguintes· conclusões:
a) Parece não haver susceptibilidade do Planorbis metidjensis, var. dufouri para o Sch. mansoni.
b) Notou-se susceptibilidade do mesmo Planorbis à infecção com ovos do Sch. haematobium da Guiné, proveniente de doentes.
e) A maior mortalidade do Planorbis metidjensis em face do Sch . mansoni do que em· face do Sch. ·haematobium faz-nos prever que ela seja devida à acção do parasita.
Although we are convinced that there is no difference between the biology of the Schistosoma haematobium of the South of Portugal and the sarne species of Africa, it is very interesting to study the susceptibility of the Planorbis metidjensis of the country to the various species of the Schistosoma. This study is made by comparing the Schistosoma haematobium of Portuguese Guinea. A it is important to appreciate its susceptibility to the Schistosoma mansoni, we have proceeded with these studies from the parasitic strain of Mozambique. We find that although disposing of a short time and insufficient and inconcrete data, we can point out the following conclusions: a) There does not seem to be any susceptibility of the Planorbis metidjensis, var. dufouri to the Schistosoma mansoni. b) We have noted susceptibility of the sarne Planorbis to the infection with eggs of Schistosoma haematobium from Guinea, obtained from patientes. e) We are obliged to foresee that the greater mortality of Planorbis-.metidjensis in view of the Schistosoma mansoni more than in view of the Schistosoma haematobium, is due to the action of the parasite.
