Abstract
Objective: To observe the ultrastructure of bacterial endosymbiont of Acanthamoeba sp.CB/S1.Methods: The endosymbionts of Acanthamoeba CB/S1 isolated from soil of China were characterized by orcein-stain under transmission electron microscopic examination.Results: Double membrane bound and rod-shaped endosymbionts were randomly distributed in trophozoites of Acanthamoeba isolate.The bacterial cell walls of endosymbionts of Acanthamoeba CB/S1 were studded with host ribosomes.Conclusion: Rode-shaped endosymbionts were randomly distributed within the cytoplasm of trophozoite of Acanthamoeba sp.CB/S1.The endosymbionts have double membranes,and the bacterial cell surfaces are studded with a number of host cell ribosomes.No specific feature could be observed within the amoeba.
