There is a wide range of bacteria that may cause skin infections. The majority of skin infections are bacterial and they are not contagious to humans. A scratch or cut on the skin can also increase the risk of skin infection.

If you have any reptiles in the surroundings, they may also get skin infections if contagious. Therefore, you have to diagnose and treat them as quickly as possible. Read more on crested gecko care.

Treatment of skin infections in crested geckos:

Some crested gecko owners try to treat minor skin infections at home by gently rubbing the infected area with a dilution of chlorhexidine solution or povidone-iodine.

The other way is to cut away seriously infected areas and to drain the blistered ulcers of the skin. Your vet will recommend a course of antibiotics after minor surgery. This minor surgery is based on the severity of the skin infection that your reptile has.

If the skin infection is more severe and it leads to fungal infections, then your vet will recommend a major surgery. The dead tissues of the skin will be removed in this surgery. This is done under anesthetic and an antibiotic will be prescribed by your vet.
