Abstract:   (2130 Views)
Aims: Burn infections are one of the most common causes of mortality in the world. On the other hand, microbial resistance to antibiotics has caused concern in the medical community. Therefore, controlling burn infections is very important, and using alternative therapies instead of antibiotics could be a good solution to this problem.
Materials & Methods: Lactobacillus plantarum 299v strains were used in the experiments. Fifty male Wistar rats were prepared, and burn was induced in animals. The burn wounds were inoculated with clinical strains of MDR Pseudomonas aeruginosa in all animals and then treated daily with an eucerin ointment containing different compositions, including NaCl, imipenem, probiotic cell pellet, probiotic supernatant, and probiotic cell pellet + probiotic supernatant. The wound healing process was evaluated in animals after 7 days of treatment. Comparisons between different groups were performed using One-way ANOVA and Turkey’s post hoc tests.
Findings: After 7 days of treatment, the mean wound size in the probiotic cell pellet group was significantly lower than in the control and imipenem groups. Also, the mean wound size in the probiotic supernatant group was significantly lower than in the imipenem group. Histological parameters related to skin repair in the probiotic cell pellet group was better than in the control and antibiotic groups. Also, inflammation in the probiotic cell pellet group was less than in the control and imipenem groups.
Conclusion: The macroscopic results of this study supported the microscopic results and showed that the mean size of the burn wounds in the probiotic cell pellet group was less than in the control and imipenem groups after 7 days of treatment.
