Occurrence of snail vectors of schistosomiasis in a dam of the semi-arid region of Pernambuco State, Brazil

[摘要] : The semi-arid region of Pernambuco state is not an endemic or focal area for schistosomiasis. The present work registers the occurrence of Biomphalaria straminea in a local dam with favorable chemical-physical characteristics to the proliferation of these mollusks. This observation gets the attention for the possibility of the introduction of the disease in this semi-arid region due to the growing multiplication of these dams.
