title: Sewage stabilization pond: The effects on Schistosoma Mansoni transmission.
abstract: The "facultative" sewage-stabilization pond was investigated with respect to transmission of S. mansoni. The results of field and laboratory experiments suggest that the ecologic factors i.e., physical and chemical play important roles in a combined interplay affecting the hatchability of S. mansoni eggs, infectivity of miracidia of S. mansioni and the potential existence of the planorbid snails host, B. glabrata. The results seem to indicate the successful reduction of S. mansoni transmission in the pond itself. If the pond is designed properly in terms of depth, detention time, etc., it will serve as an efficient barrier for transmission of S. mansoni. It is expected that the same would be true for other human schistosomes.
