Table: Some Typical Shapes, Sizes, and Arrangements of Bacteria

Keynotes

Bacteria are prokaryotic, unicellular microbes lacking chlorophyll pigments and the cellular structure is simpler than that of other microorganisms due to no nucleus or membrane-bound organelles.
The shape of a bacterium is maintained by its rigid cell wall.
Borrelia is corkscrew-shaped and is larger than the Treponema and they are visible under the microscope in Giemsa or Wright stained smears.
Treponema is only visible by a darkfield microscope.
Sizes of Microbes

Bacteria: Cocci 0.5-1.0 µm while bacilli 1-10 µm×3-10µm
Viruses: Smallest-Parvo virus-20 nm while largest –Pox virus-300 nm
Parasites: Most protozoa around 50µm in size except Balantidium coli ≥100µm. Helminthes sizes are variable-Cestodes 1mm to several meters in length while nematodes vary in size from 5mm to even 1 meter.
Fungus: Yeast-like appearance 2-30 µm, mold appearance 2-5 µm, and spherical-like appearance 5-300µm.
