Abstract
Abstract Antibiotics have shown less efficiency against resistance of pathogenic microorganisms. As a result, research centers have sought therapeutic alternatives against multidrug resistance of bacteria to antibiotics, one of which is using plant extracts. Bamboo extracts are used for several medicinal purposes. This study aimed to evaluate the antibacterial potential of hydroalcoholic extracts of culms and leaves of the species Guadua aff. lynnclarkiae on strains of Staphylococcus aureus, Streptococcus pneumoniae, and Klebsiella pneumoniae. We evaluated the minimum inhibitory concentration (MIC) and the minimum bactericidal concentration (MBC). Only the leaves of G. aff. lynnclarkiae showed a bactericidal effect for all tested strains with MBC ranging from 1.55 mg ml-1 to 25 mg ml-1. The culms had bacteriostatic action with MIC ranging from 1.55 mg ml-1 to 6.25 mg ml-1, and bactericidal action at the concentration of 6.25 mg ml-1 only for S. aureus. This study provides bases for the use of this Amazonian native bamboo in bioprospecting.
