Inclusion Criteria

1. Male or female patients aged more than 18 years.
2. Patients with a history of cardiothoracic / related leg or abdominal surgery, occurred within 30 days and no implant is left in place, and a diagnosis of SSI according to the CDC definition1, namely:
- Superficial Incisional Surgical Site Infection, involving only skin and subcutaneous tissue of the incision, and at least one of the following local findings:
· purulent drainage from the superficial incision;
· organisms isolated from an aseptically obtained culture of fluid or tissue from the superficial incision;
· superficial incision is deliberately explored by surgeon AND the patient has at least one of the following signs or symptoms of infection:
* pain or tenderness,
* localized swelling,
* redness or heat;
· diagnosis of superficial incisional SSI made by the Investigator.
Or
- Deep Incisional Surgical Site Infection, involving deep soft tissues (e.g. fascia and muscle layers) at the incision site and at least one of the following findings:
· purulent drainage from the deep incision but not from the organ / space component of the surgical site;
· a deep incision spontaneously dehisces or is deliberately opened by a surgeon when the patient has at least one of the following signs or symptoms of infection:
* fever (> 38 °C),
* localized pain or tenderness;
· an abscess or other evidence of infection involving the deep incision is found on direct examination, during reoperation, or by histopathologic or radiologic examination;
· diagnosis of deep incisional SSI made by the Investigator.
3. The severity of infection requires an IV treatment and patient hospitalization according to the Investigator’s judgment.
4. Females participating in the study must be either:
· Females of non-childbearing potential, defined as any woman who underwent surgical sterilization or is more than 2 years post-menopausal;
· Females of childbearing potential provided that they have a negative pregnancy test at Screening and are routinely using an effective method of birth control resulting in a low failure rate (i.e. hormonal contraception, intrauterine device, condoms in combination with a spermicidal cream, male partner sterilization – vasectomy– or total sexual abstinence) and continue up 30 days after last dose of study treatment.
5. Males participating in the study must agree either to abstain from sexual intercourse or to use an effective method of contraception as sterilization – vasectomy – or condom in combination with a spermicidal cream up 30 days after last dose of study treatment.

Exclusion Criteria
