Streptococcus thoraltensis in a Postoperative Wound Infection and a Therapeutic Regimen Associated with Successful Eradication

Background: Streptococcus thoraltensis is commonly isolated from swine and rabbits; however, over the past decade, it has caused various infections in human beings. The treatment of these infections is typically complex because of an association with antibiotic resistance. Case Presentation: A 20-year-old female patient presented with a postoperative surgical site infection and a positive culture for Streptococcus thoraltensis , representing a clinical combination not previously described. A favorable response was achieved by implementing a treatment regimen based on surgical wound cleansing with an isotonic and stabilized 0.057% sodium hypochlorite antimicrobial solution, followed by the application of a gel of the same composition, broad-spectrum antibiotic therapy, and the use of a Negative Pressure Wound Therapy. Conclusion: The relevance of this case lies in its presentation of a new clinical manifestation of the infection, marking the third report and fifth case described within the Mexican population. Above all, it outlines a therapeutic protocol that achieved favorable outcomes, providing a valuable reference for future cases.
