In vitro research demonstrates that peptides from Hirudo verbana reduce biofilm formation in Staphylococcus aureus, indicating potential for antibiotic-synergistic activities.
Key Points
The peptides from Hirudo verbana show significant antimicrobial effects against Staphylococcus aureus, including MRSA.
HvAMP2 exhibits MIC values of 8-16 µg/mL, inhibiting over 70% of biofilm formation at 1× MIC.
This in vitro analysis followed CLSI/EUCAST guidelines to test the peptides' activity against bacterial strains.
Findings suggest that Hirudo verbana peptides interfere with peptidoglycan synthesis and may enhance antibiotic efficacy.
