Ajoene is a sulfur-containing compound derived from garlic (Allium sativum) and has been studied for its antimicrobial properties, including activity against Staphylococcus aureus, a common cause of staph infections. Scientific studies have demonstrated that ajoene exhibits antibacterial effects, with some research indicating it can inhibit the growth of both methicillin-sensitive and methicillin-resistant Staphylococcus aureus (MSSA and MRSA). The mechanism is believed to involve disruption of bacterial cell membranes, inhibition of quorum sensing (thus interfering with bacterial communication and virulence), and synergistic effects when used in combination with conventional antibiotics.

For example, a study published in "Antimicrobial Agents and Chemotherapy" (2002) showed that ajoene inhibited the growth of S. aureus in vitro. Another study in "Journal of Applied Microbiology" (2014) found that ajoene could enhance the efficacy of antibiotics against MRSA biofilms. However, most research to date has been conducted in vitro (test tube/laboratory settings) or in animal models, and there is a lack of robust clinical studies in humans evaluating ajoene as a treatment for staph infections. While the laboratory evidence is promising and supports its potential use, more clinical trials are needed before ajoene can be recommended as a mainstream or adjunctive therapy for staph infections.

In summary, there is scientific validation for the antibacterial activity of ajoene against S. aureus, but clinical evidence in humans is limited, warranting a moderate evidence rating.
