Beautiful Bacteria

The images above are some examples of rotex fractal growth found in colonies of Bacillus subtilis. The varying branching patterns are caused by changes in the environmental conditions of the bacteria as they grow.

Prokaryote Shapes:

Bacilli- rod shaped; ex: Escherichia coli

Cocci- spherical

1. Staphylococci- “clumps” in clusters like grapes; ex: Staphylococcus aureus
2. Streptococci- “chains” of bacteria; ex: Streptococcus sp.
3. Diplococci – 2 cocci adhered to one another; ex: Neisseria gonnorheae

Spirilla– spiral-shaped with external flagella.

Spirochaetes– spiral-shaped with internal flagella, gives them a boring action; ex: Treponema pallidum (Syphilis).

Vibrio– comma-shaped bacteria; ex: Vibrio cholerae.
