Abstract

Worldwide, Staphylococcus aureus (S. aureus) infection recurrences are still occurring, and the sharp rise in antibiotic resistance makes treating these infections more challenging. Epidemics of S. aureus pose risks to public health and place a financial strain on medical expenses globally. Laboratory experiment conducted assessed and contrasted five of botanical extracts as antibacterial that have been proposed in the past as having antibacterial qualities against S. aureus to respond to the current demand for efficient treatments against this pathogen. In short, the minimum inhibitory concentration (MIC) was established after S. aureus cultures were exposed to specific botanical extracts. That study was conducted to assess antimicrobial activity of five plant extracts i.e., Salvia officinalis, Nigella sativa, Syzygium aromaticum, Myristica fragrans, Salvia rosmarinus were investigated against Staphylococcus aureus bacteria activity, using agar disc diffusion technique. The results showed that there was a large variation in the rates of inhibiting the activity of S. aureus bacteria by using these various plant extracts. The largest zone of inhibition of S. aureus bacteria activity (9.14 mm) was recorded by using Salvia rosmarinus extract, while the lowest inhibition rate was recorded (4.67 mm) by Myristica aromatic extract.
