  1. S. pyogenes (Group A)
  2. S. agalactiae (Group B)
  3. Enterococci (Group D)
  4. S. viridans.
  5. S. pneumoniae.

Why is the Gram stain considered a complex stain?

Why is the gram stain considered a differential stain? It differentiates gram-positive and gram-negative cell walls based on staining. Gram-positive bacteria have a thicker layer of peptidoglycan that retains the crystal violet-iodine complex.

What does E coli bacteria look like under a microscope?

When viewed under the microscope, Gram-negative E. Coli will appear pink in color. The absence of this (of purple color) is indicative of Gram-positive bacteria and the absence of Gram-negative E.

Is gram negative bacteria treatable?

What are the benefits of Gram positive bacteria?

Gram-positive microorganisms have several advantages for surface display applications, since their cells have only a single membrane, there is a common mechanism for surface anchoring, and bacteria can withstand rigorous manipulation conditions due to the thicker cell wall.
