[Bacteriology and disinfection of porcine skin]

Abstract:
The microbial flora and counting were studied in split porcine skin. The results indicated that the routine method for the preparation of porcine heterograft could not reduce the indigenous flora in the dermal appendages efficiently. The indigenous flora of porcine skin consists of not only Gram positive cocci and Gram negative rods, fungus are the another predominant ones, the later may contribute to the frequent complication of fungal infection and the early rejection of porcine heterograft. A tincture of iodine compound was prepared and used for the purpose of disinfection, a better result was obtained.
Insights
Routine preparation of porcine skin grafts fails to eliminate microbes. A novel iodine compound disinfection method effectively reduced microbial flora, improving graft suitability and reducing rejection risks.
Area of Science:
- Microbiology
- Biomaterials Science
- Dermatology
Background:
- Porcine heterografts are used in transplantation but face challenges with microbial contamination.
- Indigenous microbial flora in porcine skin can lead to infections and graft rejection.
- Current preparation methods are insufficient for complete microbial reduction.
Purpose of the Study:
- To investigate the microbial flora of split porcine skin.
- To evaluate the efficacy of routine preparation methods in reducing microbial load.
- To develop and assess an improved disinfection method for porcine skin grafts.
Main Methods:
- Studied microbial flora and conducted microbial counts in split porcine skin samples.
- Evaluated the effectiveness of standard porcine heterograft preparation techniques.
- Prepared and applied a tincture of iodine compound for disinfection.
Main Results:
- Routine porcine skin preparation did not efficiently reduce indigenous microbial flora, including Gram-positive cocci, Gram-negative rods, and fungi.
- Fungal presence was identified as a potential contributor to infection and early graft rejection.
- The developed tincture of iodine compound demonstrated improved disinfection results.
Conclusions:
- Standard porcine skin graft preparation is inadequate for eliminating diverse microbial contaminants.
- Fungal flora in porcine skin poses a significant risk for heterograft complications.
- Iodine compound disinfection offers a more effective approach to preparing porcine skin for transplantation.
