Evaluation of antimicrobial activity of psidium guajava species

Background The Psidium guajava, commonly known as the apple guava, has shown various biological activities related to its main constituents, such as flavonoids, carotenoids, terpenoids and phenolic compounds. Studies emphasize antispasmodic and antimicrobial properties in the treatment of diarrhea and dysentery. It also has hypoglycemiant, antioxidant, hepatoprotective, anti-allergic, antimicrobial, antigenotoxic, antispasmodic and anti-inflammatory action [1]. In the light of so many activities, it is suggested that this plant can help in controlling health-related infection, especially in areas of high microbiological risk, such as in the hospital environment. This work’s objective, therefore, was to evaluate the antimicrobial activity of the Psidium guajava.
