Wild plants are always the promising sources to explore novel therapeutic agents. Kingdom of Saudi Arabia (KSA) has a wide collection from wild and medicinal plants that contains hundreds of precious species. Staphylococcus aureus is from the most clinically dangerous bacterial pathogens that could acquire many resistance types toward numerous chemical antibiotics. Seven wild KSA plants, e.g. Bassia eriophora, Blepharis ciliaris, Ducrosia anethifolia, Pulicaria crispa, Rumex vesicarius, Tamarix aphylla and Teucrium oliverianum, were extracted with 70% ethanol solution and screened for their antibacterial activity against various S. aureus strains, including reference, methicillin susceptible (MSSA) and resistant (MRSA) strains. Most of screened extracts exhibited remarked antibacterial activity against the entire S. aureus strains; the most powerful extracts were those from B. eriophora and T. oliverianum, using different antimicrobial quantification assays. These extracts were applied onto cotton textiles as finishing agents, for the production of anti-Staphylococcus aureus fabrics; treated textiles showed powerful antibacterial activity against all examined S. aureus strains, including MRSA isolates. Extract-treated textiles could preserve most of their antibacterial activities after two laundering cycles. The present work showed that the antibacterial potentiality of KSA wild plant extracts could be proposed for the control of resistant S. aureus strains and fabrication of anti-S. aureus textiles.
