Abstract

|
|
Objectives：In this study, the in vitro antibacterial spectrum of methanol extract of Rhus verniciflua Stokes bark was determined. Antibacterial activities of the extract against clinical isolates of Staphylococcus aureus including methicillin-resistant S. aureus were also evaluated.
Methods：Agar dilution method was used to determine minimum inhibitory concentration of the extract for standard strains of Gram-positive and Gram-negative bacteria and clinical isolates of S. aureus.
Results：The extract showed activities against all standard strains tested in the minimum inhibitory concentration range 0.031-0.5 mg/ml for Gram-positive bacteria and 0.031-1 mg/ml for Gram-negative bacteria. Against methicillin-susceptible and-resistant S. aureus, the extract also showed good activity.
Conclusions：Methanol extract of R. verniciflua Stokes bark had broad antibacterial spectrum and good activity against clinical isolates of methicillin-resistant S. aureus.
