Skin protects the human body from microorganisms and several environmental hazards. There are millions of bacteria that live on the skin. These bacteria don’t cause any kind of infection since the skin stops them from entering the tissues and causing further harm by releasing harmful toxins. Nevertheless, when such bacteria do manage to enter the skin through a cut, minor injury or burn, it can cause skin infections. Let’s take a look at some of these skin infections caused by bacteria and some of the symptoms and treatments.

Skin Infection by bacteria

There are 2 main types of bacteria that have been identified to cause skin infections. These bacteria include the Staphylococcus and Streptococcus species.

Circumstances such as, diabetes, skin damage because of wounds or sunburn, autoimmune diseases and AIDS make an individual a lot more prone to bacterial skin infections.
