Abstract
Skin and soft tissue infections vary widely in their nature and severity, and their nomenclature is complex. Most are readily recognized and easily treated, but more severe infections may masquerade in forms similar to those of more innocent infections, causing delay in diagnosis and treatment that may result in loss of limb or life. Antimicrobial therapy is clearly beneficial for both recovery from these infections as well as preventing disease progression. The fluoroquinolones are potent broad-spectrum antimicrobial agents. The older fluoroquinolones mainly have excellent in vitro activity against gram-negative bacilli and borderline activity against clinically important gram-positive organisms, but newer fluoroquinolones were developed to have enhanced activity against both gram-positive and anaerobic organisms while retaining broad-spectrum anti-gram-negative activity. Several comparative trials using fluoroquinolones suggest that the efficacy of these agents is similar to that ofà-lactam antimicrobial agents. Additional clinical trials are necessary to determine the overall role of newer fluoroquinolones as alternatives for skin and soft tissue infections.
