SIZE OF BACTERIA. Bacteria are very small in size. cocci are approx. 0.5 to 1.0 μm in diameter. rods range from 2 to 5 μm in length by 0.5 to 1.0 μm in width. Spirochetes are longer (up to 20 μm) and narrower (0.1 to 1.0 μm) varies with the medium and growth phase.

Classical microbiology uses both gross and microscopic morphology to identify microbes. Gross morphology includes colony shape, size, and surface features (Fig. 2.1 ). For example, Bacillus atropheu s strain globigii produces an orange-pigmented colony on tryptic soy agar but produces small white colonies on other media.
