Venn diagram detailing the number of differentially expressed proteins in trophozoites of wild-type (WT) and nitro drug-resistant (RES) strains. Trophozoites of the resistant strains were grown in the presence of metronidazole (MET) or nitazoxanide (NTZ; both 50 μM) and subjected to MS shotgun analysis as described in Materials and methods.
