- Non-purulent infections (cellulitis and erysipelas) are most frequently caused by Streptococcus pyogenes and other β-hemolytic streptococci (BHS).1-3
- Purulent infections (abscesses and wound infections) are most frequently caused by Staphylococcus aureus including Methicillin-resistant Staphylococcus aureus (MRSA).4
- Wound infections may also be caused by Gram-negative or anaerobic bacteria.1,5,6
which include cellulitis and erysipelas, are most frequently caused by Streptococcus pyogenes and other (BHS).1-3 Cellulitis is the most common type of skin and soft tissue infection in patients who are hospitalized for treatment, accounting for close to 60% of cases.2
such as abscesses and wound infections are frequently caused by Staphylococcus aureus, including MRSA. Wound infections may also be caused by Gram-negative or anaerobic bacteria.1,5,6
MRSA accounts for nearly half (46%) of all S. aureus related SSTIs.3,6 Strains are often resistant to older antibiotics, such as macrolides, fluroquinolones and clindamycin,7 and MRSA is associated with longer hospital stays and higher healthcare costs than methicillin-sensitive S. aureus pathogens.8,9
