SEM morphology assessment of T. b. brucei GUTat 3.1 strains cultured in vitro with various treatment protocols. a Non-treated control, b suramin-treated, c vitamin D3, and d epigallocatechin gallate (an analog of green tea extract)-treated. Suramin-treated parasites showed detachment of the flagella from the body and surface damage. In cases of vitamin D3 or polyphenon-60 treatment, slight changes of the cell surface showing irregular knot-formation, there was apparent damage in the flagella structure. Arrow head showed flagella damage, and Arrow showed damaged cell membrane
