Antimicrobial and Immunomodulatory Effects of Punicalagin and Meropenem in a Murine Model of Sublethal Sepsis.

Punicalagin (Pg), a major ellagitannin derived from pomegranates, possesses antimicrobial, antioxidant, and immunomodulatory properties, suggesting its potential as an adjunctive therapy for sepsis. This study investigated the synergistic effects of punicalagin and meropenem in a murine model of sublethal sepsis induced by cecal ligation and puncture (CLP). Mice were treated with punicalagin and meropenem, and multiple parameters were analyzed, including hematological indices, bacterial burden, lymphoid organ cellularity, cytokine profiles (IL-2, IL-4, IL-6, IL-10, IL-17, IFN-γ, TNF-α), nitric oxide (NO) production, and organ histopathology.

Antioxidant and Antimicrobial Properties of Probiotics: Insights from In Vitro Assays.

Probiotics are microorganisms that provide health benefits at adequate doses and exhibit notable antioxidant and antimicrobial activities. These properties play crucial roles in combating chronic diseases linked to oxidative stress and antimicrobial resistance. This review aimed to summarize the antioxidant and antimicrobial properties of probiotics determined in in vitro studies and discuss mechanistic actions and analysis methods.

Therapeutic Potential of and Isolated Compounds: Evidence-Based Advances to Treat Bacterial Infections.

Linn has been known for its nutritional and medicinal value since ancient times and is used in the treatment of various pathologies owing to its antibacterial properties. This review reports the results of the most recent studies on the antibacterial effects of and its isolated compounds on bacteria of clinical interest. A search in the PubMed, Scopus, Science Direct, and Science Citation Index Expanded (Web of Science) databases was performed, which included articles that evaluated the antibacterial activity of extracts and excluded articles that analyzed other microorganisms or nonpathogenic bacteria, as well as theses, dissertations, duplicate articles, and those not fully available.
