When viewed under light microscope, most bacteria appear in variations of three major shapes: the rod (bacillus), the sphere (coccus) and the spiral type (vibrio). They measure about 0.25 Âµ and are the smallest cells known so far. 2  They were formerly known as pleuropneumonia-like organisms (PPLO). 3  Mycoplasma gallicepticum, with a size of approximately 200 to 300 nm are thought to be the world smallest bacteria.
