Abstract

Background: Streptomyces, a genus of Actinomycetes, are known for their ability to produce bioactive compounds, including antibiotics, with significant applications in medicine and agriculture.
Objective: This study’s aim is to investigate the effects of extracellular extracts from Streptomyces spp. on the inflammatory response, specifically interleukin-6 (IL-6), in various bacterial infection models.
Methods: Through 16S rRNA gene sequencing, the T2 strain was identified and shown to share a high similarity with S. actinomycinicus. Phylogenetic analysis confirmed its close evolutionary relationship with other species in the Streptomyces genus.
Results: The study found that IL-6 levels were significantly elevated in infections caused by both sensitive and resistant bacterial strains, with resistant strains showing the highest inflammatory response. Post-infection treatment with Streptomyces extracts effectively reduced IL-6 levels in sensitive bacterial infections, demonstrating the extract’s potential antimicrobial properties. However, the treatment had limited effectiveness in resistant infections, as indicated by persistent high IL-6 levels. The extract alone did not significantly alter IL-6 levels, suggesting anti-inflammatory properties without triggering an immune response.
Conclusion: Streptomyces extracts may reduce bacterial load and inflammation in infections, but limited effectiveness on resistant strains necessitates further research for more potent antibiotic-resistant treatments.
