Overview
Impetigo is usually caused by Staphylococcus aureus. Streptococci (e.g. Streptococcus pyogenes) have been associated with the non-bullous form of impetigo and ecthyma.Streptococci can either infect individually or co-infect with Staphylococcus aureus. Non-bullous impetigo makes 70% of all the caess of impetigo.[1][2][3][4]
Causes
It was previously believed that non-bullous impetigo is caused by group A streptococci whereas Staphylococcus aureus causes the bullous subtype of impetigo. Both bullous and non-bullous subtypes of impetigo are now understood to be primarily caused by S. aureus. Streptococci have been associated with the non-bullous form and ecthyma.[3][5][6][7]
Common causes
The common causes of impetigo include:[8][9][10][11]
- Staphylococcus aureus
- Methicillin-resistant Staphylococcus aureus (MRSA)
- Gentamicin-resistant Staphylococcus aureus
Bullous Impetigo
Non-bullous Impetigo
Ecthyma
Drug Induced
