Spirochetes Gram negative Long, thin, helical spirochete from Greek for“ coiled hair” Periplasmic flagella(axial fibrils or endoflagella),-mobile -differering numbers of endoflagella according to genus species Outer sheath encloses axial fibrils wrapped around protoplasmic cylinder A helical protplasmic cylinder with a peptidoglycan layer similar to G B outer membrane, cytoplasmic membrane, and cytoplasm axial filaments locomotion between peptidoglycan layer/outer membran
