A Study to Evaluate the Safety and Bioequivalence of Mupirocin Calcium Cream, 2% and Bactroban® Cream and Compare Both to a Vehicle in Treatment of Secondarily Infected Traumatic Skin Lesions.

The primary objective of this study is to determine the comparability of the safety and efficacy of Mupirocin Calcium Cream, 2% and Bactroban® Cream in subjects with secondarily infected traumatic skin lesions. It will also be determined whether the efficacy of each of the active treatments is superior to that of the vehicle cream (placebo).

* The laceration or sutured wound should not exceed 10 cm in length with surrounding erythema not more than 2 cm from the edge of the lesion. An abrasion should not exceed 100 cm2 in total area with surrounding erythema not more than 2 cm from the edge of the abrasion.
* Positive baseline culture for S. aureus and/or S. pyogenes from a sample taken from the secondarily infected traumatic skin lesion.
* Positive Gram stain or Wright stain for confirmation of white blood cells in the pus/exudate from the secondarily infected traumatic skin lesion.

* Secondarily infected bite or puncture wound.
* Systemic signs or symptoms of infection.
* Requirement for surgical intervention for treatment of the infection prior to study entry.
* A subject must not have received any topical corticosteroid, topical antibiotic, or antifungal agent for at least 48 hours (2 days) prior to baseline.
* A subject must not have received any systemic antibiotic or systemic corticosteroid for at least 7 days prior to baseline.
