Treponema pallidum. Illustration based on a Scanning Electron Micrograph (SEM) of T. pallidum,the bac- teria that causes syphilis. T. pallidum is a long thin,spiral-shaped bacteria,classed as gram- negative. The white line running along its length is a whip-like organ called a flagellum,which allows the bacteria to move. In this species the flagellum is enclosed within the cell's outer en- velope,and is called a periplasmic flagellum. Although once common,the sexually transmitted disease syphilis has declined thanks to the use of penicillin. Magnification unknown | |
