Zizyphus joazeiro Mart. Tree fairly widespread in northeastern Brazil, used as oral hygiene agent, to replace commercial products. It is used in the fruit disorders of the stomach and the shells in wound healing, fevers and infections of the lungs. The present study aims to evaluate the antimicrobial activity in vitro of different extracts of Zizyphus joazeiro Mart opposite the microorganisms, including yeasts, Gram-positive, Gram-negative and Mycobacterium bovis. The extracts were prepared using the aerial parts (stem bark, leaves and fruits) of Zizyphus joazeiro Mart. These were tested for their antimicrobial activity against yeasts and bacteria using the agar diffusion method. All extracts showed antimicrobial activity. The microorganisms used only Bacillus subtilis, Staphylococcus aureus and Candida albicans were susceptible. None of the tested extracts showed activity on Mycobacterium bovis. These results may partly explain the use Zizyphus joazeiro Mart. for the treatment of infectious diseases in traditional medicine.
