IN-VITRO ANTIBACTERIAL ACTIVITY OF PSIDIUM GUAJAVA L. LEAF EXTRACTS AGAINST CLINICALLY IMPORTANT PATHOGENS Staphylococcus aureus AND Escherichia coli.

Microbiology

Today, around 80% of the world's population uses plants that have been used for thousands of years to cure a variety of diseases due to their effectiveness, availability, and lack of adverse effects. The crude extract of the psidium guajava leaves exhibited antibacterial and antifungal properties. In this work, p.guajava linn leaf extract was tested for its ability to combat both gram-positive and gram-negative bacteria. Guava plants that have been used for the treatment of various diseases for thousands of years due to their effectiveness, availability, and lack of side effects. These plants are used to link the activity of bacteriostatic and fungistatic strains using the turbidity method and to link that activity to the plants components. P.guajava water extract is has antibacterial action against Escherichia coli and staphylococcus aureus. It indicates via Minimum Bactericidal Concentration (MBC), Minimum Inhibitory Concentration (MIC), and Antibacterial Sensitivity (ABST) techniques. Guava leaf extract is an important source of antibacterial agent since it is effective against Staphylococcus aureus and Escherichia coli.
