Abstract
The aqueous and alcoholic extracts of 15 plant species, all of them used in folk medicine as vulnerary, were tested for antibacterial activity.
The bacteria used were Enterococcus faecalis (resistant to oxacillin, penicillin-G, rifampicin and cephalothin), Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeuruginosa (resistant to nalidixic acid, ampicillin, cephalothin, nitrofurantoin, cefotaxime), Serratia marcescens (resistant to nalidixic acid, cephalothin, nitrofurantoin, ampicillin, gentamicin). Staphylococcus aureus (Penicillin-G resistant), Streptococcus agalactiae, Streptococcus pyogenes. The extracts tested showed several degrees of antimicrobial activity against Gram-positive and Gram-negative microorganisms.
