Final answer:
Mebendazole is used to treat cestode infections by interfering with microtubule formation. It can affect protozoa, fungi, and viruses, but not bacteria or human cells.
Step-by-step explanation:
Mebendazole is used to treat cestode infections by interfering with microtubule formation, which leads to a reduction in glucose uptake in the intestinal cells of the worms.
While its primary target is helminths, it can also affect other organisms such as protozoa, fungi, and viruses.
However, mebendazole would not affect bacteria or human cells since they have different cellular structures and processes.
