F.  aInfection of Fasciola hepatica (DigenabFasciolidae) with Nosema algerae (Microscoporida: Nesomatidae) during development in Lymnaea cubensis (Basommatophora: Lymnaeidae).  aGainesville: University of Floridac1978  a96p.  aTese Mestrado  aThe present experimental work was designed to investigation the degree of susceptibility of the snail, Lymnaea cubensis, and of the intrasnail larval stages of E. hepatica to infection by N. algerae, a microsporidian pathogen originally describe in mosquitoes. A second objective was to measure the influence of F. hepatica infection on the susceptibility of L. cubensis to the microsporidian infection. In this connection, a modified method for laboratory colonization of L. cubensis was developed and evaluated, based on snail mortality and metacercariae production. Because the snail colony was formed with snails originally collected from two georgraphic areas in Florida, the susceptibility of these snails to F. hepatica was also compared.  aMamífero  aMolusco  aTrematódeo  aControl  aControle  aMammal  aMollusk  aTrematode
