ACANTHAMOEBA CULBERTSONI PDF

Several species of Acanthamoeba, including A. culbertsoni, A. polyphaga, A. castellanii, A. astronyxis, A. hatchetti, A. rhysodes, A. divionensis. In order to define the mode by which amoebae recognize ECM components and process this recognition, we analyzed Acanthamoeba culbertsoni attachment. They have been implicated in human infections and disease, including Acanthamoeba culbertsoni, Acanthamoeba polyphaga, Acanthamoeba castellanii.
