It is known that about 400 plant species are used by semi-arid local communities for medical purposes. Based on ethnopharmacological reports, this study aims to screen 24 species from Caatinga regarding the ability to prevent biofilm formation and to inhibit the growth of Pseudomonas aeruginosa - a major opportunistic human pathogen and an important causative agent of morbidity and mortality.
The effects of aqueous extracts, at 0.4 and 4.0 mg mL-1, on biofilm formation and on growth of P.
aeruginosa ATCC 27853 were studied using the crystal violet assay and the OD600 absorbance, respectively.
