Amebae were characterized on the basis of morphologic criteria (cyst morphology and trophozoite shape and motility) (5).
can cause severe infections, amebae also carry pathogenic microorganisms (4).
Some of these mycobacteria already had been shown to survive in free-living amebae
and to be implicated in human diseases, such as M.
