  5. Aug 31, 2023 · There are three basic shapes of bacteria: coccus, bacillus, and spiral. Based on planes of division, the coccus shape can appear in several distinct arrangements: diplococcus, streptococcus, tetrad, sarcina, and staphylococcus. The bacillus shape can appear as a single bacillus, a streptobacillus, or a coccobacillus.

  6. Jan 1, 2008 · E. coli is Gram-negative and its envelope has three layers: cytoplasmic membrane, peptidoglycan, and outer membrane. The peptidoglycan is rigid determining the rod shape. To a good approximation, the E. coli cell has hemispherical caps and a cylindrical section in between.
