Study of antimicrobial, antifungal and healing properties of Kefir

Introduction. Kefir is a symbiotic association of microorganisms prepared from Kefir grains. Objective. The antibacterial, antifungal, and healing activity of Kefir was evaluated. Material and methods. Antibacterial and antifungal properties was carried out against some pathogenic microbial species, such as Staphylococcus aureus, Pseudomonas aeruginosa, Eschirichia-coli, Salmonella typhi, enterobacterococcus faecalis, Klebsiella pneumoniae, and Candida albicans, by the agar disk diffusion method and by well. Healing experiments were carried out in adult Wistar rats, with skin burns, using a topical application of two milk, and fruit kefir gels, and silver sulfadiazine. Results. Kefiran, an exopolysaccharide of Kefir, had antibacterial anti Staphylococcus activity and anti-candidal antifungal activity. Kefir gels had better wound healing compared to silver Sulfadiazine, with a protective effect on skin, and connective tissue, after a 15-day treatment ofrats. Conclusion. Kefir is a natural probiotic with multiple virtues. Indeed, Kefiran has an anti staphylococcus activity, and an anti candidias activity. Healing activity of Kefir gel is an effective therapeutic approach to improve healing, after a severe burn, compared to a conventional treatment with silver Sulfadiazine.
