New Research on Staphylococcus aureus Highlights the Potential of Probiotics in Skin Dysbiosis

Strategic Insights -

Researchers at Cracow University of Technology have made significant findings on the use of probiotics in managing skin dysbiosis, a condition associated with numerous skin conditions. According to the study, a novel probiotic formulation based on Lactobacillus casei ATCC 393 has shown antimicrobial activity against Staphylococcus aureus and Staphylococcus epidermidis. The study also explored the use of alginate-prebiotic encapsulated probiotic strain microspheres as active ingredients in a topical formulation, demonstrating its safety and efficacy in vitro.

Key Takeaways:

  • The study highlights the potential of probiotics in managing skin dysbiosis, a condition associated with numerous skin conditions.
  • The novel probiotic formulation based on Lactobacillus casei ATCC 393 has shown antimicrobial activity against Staphylococcus aureus and Staphylococcus epidermidis.
  • The use of alginate-prebiotic encapsulated probiotic strain microspheres as active ingredients in a topical formulation demonstrated safety and efficacy in vitro.
  • The formulation exhibited regenerative potential in the scratch test and reduced the survival of pathogenic strains compared to the base formulation.
  • The study suggests that probiotics may be used as modulators to restore microbial balance in the skin.
  • The research was conducted by Anna Letocha, Cracow University of Technology, Department of Organic Chemistry and Technology, Faculty of Chemical Engineering and Technology, along with Alicja Michalczyk, Ewa Bielecka, Tomasz Kantyka, Malgorzata Miastkowska, and Elzbieta Sikora.

Statistics:

  • The probiotic formulation resulted in a 0.81 and 0.99 log reduction of Staphylococcus aureus cells after 5 and 24 hours, respectively.
  • The zone of inhibition in the well diffusion assay was 5 mm, indicating the presence of active metabolites against Staphylococcus aureus.
  • The formulation containing MP reduced the survival of pathogenic strains (E. coli, S. aureus, C. albicans, C. neoformans) by 2.82 log compared to the base formulation.
