Journal Article}, pages = {356-8}, abstract = {The cercarial emergence rhythms of Schistosoma mansoni were analyzed for mixed infection of the snail Biomphalaria glabrata with two chronobiological strains, one with an early shedding pattern and the other with a late shedding pattern. Under these conditions, each parasite strain kept its own circadian cercarial emergence pattern. When the chronobiological variants were of the same species, no interference between the trematode larvae occurred during the cercarial emergence process. These results confirm that within the host-parasite system the parasite component is directly responsible for the cercarial emergence pattern.}, keywords = {*Periodicity, Animal, behaviour, Biomphalaria/*parasitology, cercaria, Comparative Study, Oman, Schistosoma mansoni/classification/physiology, Schistosomiasis mansoni/*parasitology, Species Specificity, Support, Non-U.S. Gov{\textquoteright}t}, author = {Th{\'e}ron, A. and Mouahid, G. and Mon{\'e}, H.} }
