Immunological Parameters of the Pomacea lineata Spix, 1827 (Mollusca: Caenogastropoda) Exposed to Schistosoma mansoni Sambon, 1907

Introduction Pomacea lineata acts as the natural biological controller of Biomphalaria glabrata, the intermediate host of Schistosoma mansoni, as they are found in the same environment. However, there are no studies reporting an infection in P. lineata due to S. mansoni. Thus, this work investigated parameters related to the immunity of P. lineata after exposure for 24 and 48 h to S. mansoni under experimental conditions.
