%X Nootka rose (</span><i><span style=\"font-family:Verdana;\">Rosa
nutkana </span></i><span style=\"font-family:Verdana;\">C. Presl) and stinging nettle (</span></span><i><span style=\"font-family:Verdana;\">Urtica dioica </span></i><span style=\"font-family:Verdana;\">L.</span><span style=\"font-family:&quot;\"><span style=\"font-family:Verdana;\">) have been traditionally used in the treatment of
skin infection by Indigenous peoples of Vancouver Island, British Columbia,
Canada. The main objective of this study was to examine the antibacterial
efficacy of extracts of Nootka </span><span style=\"font-family:Verdana;\">rose and
stinging nettle against the common pathogenic skin bacteria</span> </span><i><span style=\"font-family:Verdana;\">Staphylococcus aureus</span></i><span style=\"font-family:&quot;\"><span style=\"font-family:Verdana;\">,</span><i><span style=\"font-family:Verdana;\"> Micrococcus
luteus</span></i><span style=\"font-family:Verdana;\">, and </span><i><span style=\"font-family:Verdana;\">Pseudomonas aeruginosa</span></i> </span><span style=\"font-family:Verdana;\">using </span><span style=\"font-family:Verdana;\">Indigenous science and
standard methods of analysis. The Indigenous science method of plant extraction
by steeping as advised by the Traditional Knowledge keeper</span><span style=\"font-family:Verdana;\"> was performed to examine minimum inhibitory concentration </span><span style=\"font-family:Verdana;\">(MIC) </span><span style=\"font-family:Verdana;\">values and minimum
bactericidal concentrations </span><span style=\"font-family:Verdana;\">(MBC) by serial dilution and
bacterial population counts. </span><span style=\"font-family:Verdana;\">Soxhlet extractions and Kirby Bauer disc sensitivity
testing showed that Nootka rose </span><span style=\"font-family:Verdana;\">extracts
possessed antibacterial effectiveness against all three bacterial species while
stinging nettle extracts were effective against </span><i><span style=\"font-family:Verdana;\">M. luteus</span></i><span style=\"font-family:&quot;\"><span style=\"font-family:Verdana;\">. Results for MIC and MBC
indicated antibacterial activity against </span><i><span style=\"font-family:Verdana;\">M.
luteus</span></i><span style=\"font-family:Verdana;\"> and </span><i><span style=\"font-family:Verdana;\">S. aureus</span></i><span style=\"font-family:Verdana;\"> for the </span></span><span style=\"font-family:Verdana;\">Nootka rose when using </span><span style=\"font-family:&quot;\"><span style=\"font-family:Verdana;\">full-strength solutions; all
three bacterial species
