Skin infection or bacterial skin infection is a disease caused by harmful bacteria that attack the skin and related structures, this disease can be classified into:

Impetigo; Small skin abscess. Meanwhile, acute skin infections and skin structure infections are more complex bacterial skin infections, including:
Cellulitis ; erysipelas ; Wound infection; Large skin abscesses (skin over 75cm2 edematous, hard and red). Patients with skin and soft tissue infections are mainly caused by two types of bacteria, streptococcus (Streptococcus) and staphylococcus (Staphylococcus), including methicillin-resistant staphylococcus (MRSA). MRSA is a group of bacteria that are resistant to many antibiotics. Therefore, the antibiotic recommended for the treatment of soft tissue skin infections will depend largely on the local morphological prevalence and antibiotic resistance patterns of MRSA.
