Gram Positive Rod-Shaped Bacteria Vs Gram-Negative Rod Shaped Bacteria
Some gram positive and gram negative bacteria difference are given below:
Characteristics | Gram-Positive Bacteria | Gram-Negative Bacteria |
---|---|---|
Retention of Crystal Violet Dye | Retains the dye. | Does not retain the dye. |
Colour observed |
Violet or blue under microscope. |
Red or pink under microscope. |
Cell Wall Composition | Thick peptidoglycan layer. | Thin peptidoglycan layer in periplasmic space, additional outer lipid membrane (lipopolysaccharide). |
Endotoxin Presence | Absent | Present |
Resistance to Antibacterial Treatments | Generally less resilient | More resilient due to protective outer membrane. |
Outer Membrane Permeability | Not present | Selectively permeable |
Additional Structures | May have surface appendages (e.g., pili) | Often equipped with pili or fimbriae for adhesion to host cells |
Rod-Shaped Bacteria
Rod-shaped bacteria, as the term suggests, have a cylindrical structure. They belong to the category of bacilli in bacterial classification. Characteristics of rod-shaped bacteria show their ability to form spores, which gives them an advantage in surviving harsh environments. Rod-shaped bacteria are classified as either Gram-positive or Gram-negative.
There are certain kinds of diseases caused by rod-shaped bacteria like Typhoid, etc. The rod-shaped bacteria examples are Salmonella typhi, Streptobacilluls, Brucella, etc. In this article, we will read about rod-shaped bacteria, their types, examples, and the significance of rod-shaped bacteria.
