Gram-positive vs. gram-negative bacteria

Streptococcus bacteria

Ever wondered why the scratch on your arm turned leaky and began to hurt? Ever wondered why that lesion on your skin started secreting yellow pus from it? This is because of the contamination of the skin by bacteria. Now these bacteria are of two types’ gram-positive and gram-negative. The gram-positive bacteria appear blue and the gram-negative bacteria appear pink in color as seen under the microscope. In this article, we’ll discover the differences of Gram-positive vs. Gram-negative bacteria.


The gram-positive bacteria, between the two, is normally living on the surface of our skin and just live about their lives causing no harm to us. This is their natural habitat and everybody on this planet has these bacteria on their skins. These bacteria may come either from the air, dust, or during contact with a dirty thing or they just might be living on the skin naturally. To have a comparison between the two types of bacteria and their infections caused in the skin, the gram-positive bacteria are more important to be aware of.

The need to know this technical thing is that you must be aware of the type of bacteria that is infecting your skin. Based on that different treatment options can be utilized which would otherwise be a confusing thing to ascertain.

How bacteria causes a skin infection

Skin problems arise when bacteria get access to the skin due to skin damage. These bacteria then enter the layers of the skin as small evil soldiers with weapons and ammunition ready inflict damage. Fortunately, most of this damage in the form of infections is fought off with the help of our immune system. The immune system and its components in your body acts as the friendly soldiers who are equipped with latest technology and defense equipment to fight off the bad soldiers of the bacteria.

Resultantly, the immune cells in our blood cordons off the bacteria contamination in our skin and keeps it localized.

Gram-positive vs. Gram-negative bacteria

Common gram-positive infections

Examples of such infections are:

  • Impetigo
  • Ecthyma
  • Folliculitis
  • Furunculosis
  • Carbuncle

Folliculitis is when there is an infection of the skin right at the root of the hair on your skin.  Impetigo is a skin infection in children mostly. Ever seen a honey-colored crusted rash on the skin of a child? That’s impetigo caused by gram-positive bacteria. Sometimes the gram-positive bacteria reach the deeper layers of the skin causing widespread skin infections like cellulitis and necrotizing fasciitis.

Common gram-negative infections

Gram-negative bacteria normally do not live on the surface of the skin as a part of their natural flora like the gram-positive bacteria do. Hence the only way for gram-negative bacteria to reach your skin is that the germs to enter the skin from external sources. These bacteria can also infect the skin causing small pustules or breaks in the skin with bleeding and blackening of the skin.

Imagine the above different examples of skin infections with the help of the following analogy. Suppose there are various soldiers of various body types with different weapons. Each soldier having a specific ability to inflict attack on your skin. Now it is up to the defense mechanism and defense equipment of your skin that will determine whether it will resist the attack of the bacteria successfully or will succumb to those nasty little infectious soldiers.

Skin infection and awareness

If you ever feel that there is redness on your skin which is tender and hot to the touch, you should think of a cutaneous skin infection caused by gram-positive or gram-negative bacteria. The differentiating factor of Gram-positive vs. Gram-negative bacteria infection lies in diagnostic investigations that a dermatologist would like to order on your skin. The dermatologist might take a sample of the infected skin and observe it under a microbe to see the type of bacteria.
