Erysipelas is primarily caused by Streptococcus bacteria. This bacterial infection commonly occurs when these bacteria enter the skin through a break or crack.
Understanding the Primary Culprit: Streptococcus Bacteria
The most common pathogen responsible for erysipelas is a type of Streptococcus bacteria. These bacteria are widespread and can cause various infections, but in the context of erysipelas, they specifically affect the superficial layers of the skin and the lymphatic vessels within them.
How the Infection Develops
The development of erysipelas hinges on the entry of Streptococcus bacteria into the skin. This typically happens when the skin's protective barrier is compromised, allowing the bacteria to penetrate. Potential entry points include:
- Minor cuts or abrasions: Even small nicks or scrapes can provide an opening.
- Insect bites: Punctures from insect bites can break the skin.
- Surgical incisions: Healing wounds can be susceptible to bacterial invasion.
- Skin conditions: Existing skin issues like eczema, athlete's foot, or psoriasis that cause cracks or open sores can facilitate bacterial entry.
- Ulcers or sores: Any open wound provides a direct pathway for infection.
Once the bacteria gain access, they multiply and spread, leading to the characteristic symptoms of erysipelas, such as a bright red, swollen, and warm rash with a distinct raised border. The infection can affect individuals of all ages, including both adults and children.
