Spirochaetes are spiral or helical Gram-negative bacteria. They are motile organisms as they have endoflagella. They have lengths between 5 and 250 µm. They are sensitive to dessication and survive poorly in the environment.  

Spirochaetes are spiral or helical Gram-negative bacteria. They are motile organisms as they have endoflagella. The position of their flagella is used to distinguish this bacteria, they run length ways and cause a twisting motion. They have lengths between 5 and 250 µm. They are sensitive to dessication and survive poorly in the environment.
