Demonstrates effective antibacterial properties of guava leaf extract against Staphylococcus aureus and Escherichia coli, suggesting its potential in treating wound infections.

Key Points

To determine the effectiveness of different concentrations of guava leaf extract as an antimicrobial agent.
Extracted dried guava leaves at concentrations of 50%, 75%, and 95%.
Cultured Staphylococcus aureus and Escherichia coli on Mueller–Hinton agar.
Incubated cultures at 37°C for 24 hours to observe zones of inhibition.
The 95% guava leaf extract showed a 22.33 mm zone of inhibition against Escherichia coli.
The 50% guava leaf extract exhibited a 15.67 mm zone of inhibition against Staphylococcus aureus.
