dc.description.abstractBackground: Anti-microbial resistance has become a major problem in clinical practice making it necessary to search for newer molecules. Acalypha wilkesiana, is a herb commonly used traditionally in Nigeria to treat gastrointestinal disorders, wounds and skin infections like impetigo. Objectives: To determine the in-vitro anti-bacterial activity of crude extracts of 2 cultivars of Acalypha wilkesiana (Macrophylla & Hoffmanii) Methods: In-vitro antibacterial activity was investigated by agar diffusion and micro-broth dilution techniques. Bacterial isolates tested were Escherichia coli, Methicillin Resistant Staphylococcus aureus, Staphylococcus aureus, Salmonella paratyphi, Pseudomonas aeruginosa and Klebsiella pneumoniae. Results: The ethanol extract of both cultivars were more active than the ethyl acetate and n-hexane extracts having diameter zones of inhibition against all the bacteria tested at a range of 12.00-22.00 mm. The lowest MIC of the crude ethanol extract was seen with E. coli (1000 µg/ml) and S. aureus(1000 µg/ml; 2000 µg/ml) while the most active fractions (R2, R4, G3 and G4) of the crude ethanol extract of both cultivars had greatest activity against MRSAand P. aeruginosa (156 µg/ml). Conclusion: This study shows that Acalypha wilkesiana has good broad spectrum anti-bacterial activity with the potential for development as lead compounds to combat multi-drug resistant organisms like MRSA.en_US
