Abstract:
The surface charge of Giardia lamblia trophozoites from axenic cultures of strains recently isolated in Mexico from human cases of symptomatic and asymptomatic giardiasis was studied by means of cellular microelectrophoresis and ultrastructural cytochemistry. It is concluded that ionogenic surface groups confer a negative surface charge on trophozoites of G. lamblia and that no significant differences exist between the surface charge of trophozoites of symptomatic and asymptomatic origin.
