“The minimum inhibitory concentration (MIC) of the extract was 4-16 mg/ml while its bactericidal action (MBC) was exerted at higher doses (16-64 mg/ml).”
“The extract (5 mg/ml) produced antimicrobial action in agar diffusion assays against standard strains of Gram-positive bacteria including Bacillus subtilis, Staphylococcus aureus, and Streptococcus faecalis while exerting only slight action against Escherichia coli, Serratia marcescens, Candida utilis, and Aspergillus niger.”
“The extract therefore, appears to possess a narrow spectrum of antimicrobial activity, being effective against only the Gram-positive bacteria used in our study.”
