Inroduction The spirochetes are a large heterogenous group of bacteria In some respects, this microorganism is similar to bacteria and protozoa. They have cell wall and propagate by binary fission and move vigorously by the rotation and twisting of the endoflagella. They are sensitive to antibiotic
