Abstract:

The leaves of Guava is used in the treatment of the Acute diarrheal diseases, Bronchitis, asthma attacks, cough, pulmonary diseases could be also treated with guava teas and could also be useful as anti-inflammatory and haemostatic agent. Aim of the Research work was to find out the antibacterial and antifungal activity of guava leaves extract. This work was carried out in the Laboratory of Microbiology Department, Hazara University Manshera, Khyber Pakhtoonkhwa, Pakistan, during the month of January 2013.The methanol, acetone and N, N-dimethyl formamide (DMF) fractions of leaves of Psidium guajava L. were evaluated for antibacterial and antifungal activity. Piperacillin and gentamicin were used as standards for antibacterial assay, while nystatin and flucanazole were used as standards for antifungal assay. Twenty three (23) important microorganism was used were used for the study which were unidentified isolates as well as identified strains. The antibacterial activity was more pronounced against fungal strains. Moderate activity was shown against the gram-negative bacterial strains studied.
