In addition, the presence of multidrug-resistant (MDR) pathogens doubles the treatment problems. Lactobacillus plantarum (L. plantarum) is a well-known antibacterial and healing agent that could be used topically to treat burn wounds. Case Series Presentation:This clinical trial study (Case Series) was performed on 20 patients with deep second-degree burns. Patients had bilateral wounds; the wound on one side of the body was considered as control (treated with silver sulfadiazine) and the other side of the body as treatment (treated with bacteria-free supernatants (BFS) of L. plantarum). The wounds were evaluated by microbial assessments and assessments related to healing. Pseudomonas aeruginosa, Klebsiella pneumonia, and Staphylococcus aureus were isolated from 4 (22.2%), 0%, and 2 (11.1%) of wounds treated with L. plantarum on the fifth day of the treatment, respectively. Furthermore, 12 (66.7%) of wounds treated with L. plantarum were free from bacteria. The need for skin grafting was the same in both treatment and control groups, but graft rejection in the group treated with L. plantarum was (0%) (P=0.02). Conclusion:Regarding eliminating or reducing infection and wound healing, bacteria-free supernatants of L. plantarum can be considered a possible topical treatment option in the case of second-degree burn wounds.

Background: Microbial infections and the resistance to antibacterial drugs are on the rise, and scientists are in search of the safest and most effective approach to overcome them. Medicinal plants are potentially effective against many microorganisms. Therefore, this study was planned to examine the antibacterial properties and cytotoxicity of the extracts of Allium sativum and Myrtus communis against bacteria that cause nosocomial infections. Methods: A. sativum and M. communis were collected from the northern regions of Iran during the spring. After preparing the hydroalcoholic extracts of A. sativum and M. communis, the minimum inhibitory and bactericidal concentrations (MIC & MBC) were determined. The cytotoxicity of the extracts was asseyed in normal cells and Hu02 fibroblast cell line. Results: The MIC and MBC of A. sativum (62.5 mg/mL) against Salmonella enterica were similar. Also, the MIC of A. sativum and M. communis against Acinetobacter baumannii and Pseudomonas aeruginosa were similar (62.5 & 15.6 mg/mL), respectively. The viability percentage of skin fibroblasts after treatment for 48 hours with the extract of A. sativum was significantly higher than that of M. communis. Conclusion: Both extracts from A. sativum and M. communis demonstrated good antimicrobial properties. Based on the results, the safe antibacterial potential of the extracts may be used as alternative agents to fight against nosocomial bacterial infections.
