The increasing occurrence of hospital‐acquired infections and the emerging problems posed by antibiotic‐resistant microbial strains have both contributed to the escalating cost of treatment. The presence of infection at the wound site can potentially stall the healing process at the inflammatory stage, leading to the development of a chronic wound. Traditional wound treatment regimes can no longer cope with the complications posed by antibiotic‐resistant strains; hence, there is a need to…

Promising Antibacterial Effects of Silver Nanoparticle-Loaded Tea Tree Oil Nanoemulsion: a Synergistic Combination Against Resistance Threat
TLDR
Results of the antibacterial assays showed promising ability of the designed nanosystem for eradication of Gram-positive and Gram-negative bacteria and it was shown that introducing colloidal Ag NPs to the TTO NE exerted a synergistic effect against Escherichia coli.

TLDR
Results of this study showed that all oral streptococci exhibited biofilm formation with varying degrees and cinnamon, clove, eucalyptus, followed by tea tree oil not only had a distinctive antibacterial activity against oral Streptococcal isolates, but also possessed anti-biofilm activity.
Antimicrobial Silver Nanoparticles for Wound Healing Application: Progress and Future Trends
TLDR
This review aims at providing the reader with an overview of the most recent progress in silver nanotechnology, with a special focus on the role of silver in the wound healing process.
Antibacterial Activity and Mode of Action of β-caryophyllene on Bacillus cereus
TLDR
The results revealed that β-caryophyllene was able to alter membrane permeability and integrity of B. cereus, leading to membrane damage and intracellular content leakage, which eventually caused cell death.
Comparison of the efficacy of tea tree (Melaleuca alternifolia) oil with other current pharmacological management in human demodicosis: A Systematic Review
TLDR
TTO (especially T4O) is found to be the most effective followed by metronidazole, ivermectin and permethrin in managing the Demodex mite population and the related symptoms and further research needs to be focused on the efficacy and drug delivery technology in order to develop alternative treatments with better side-effects profiles, less toxicity, lower risk of resistance and are more cost-effective.
Treatment Strategies for Infected Wounds
TLDR
This paper presents an overview of the most prominent antibiotic-embedded wound dressings, as well as the limitations of their use, and highlights recent advances in using nanoparticles as platforms to increase the effect of pharmaceutical formulations aimed at wound healing.
Silver complex of salicylic acid and its hydrogel-cream in wound healing chemotherapy.
Bacterial resistance to antibiotic alternatives: a wolf in sheep’s clothing?1
TLDR
This review focuses on phage, essential oils, direct-fed microbials and bacteriocins, metals and minerals, and organic acids, which use very different approaches to regulate both commensal and pathogenic bacterial populations.
The theoretical substantiation of the composition of a wound-healing ointment with active components of plant origin
Aim. To theoretically substantiate the composition of a wound healing ointment with active substances of plant origin for the therapy in the second and third phases of the wound process. Materials…
Can the tea tree oil (Australian native plant: Melaleuca alternifolia Cheel) be an alternative treatment for human demodicosis on skin?
TLDR
Although current treatments other than TTO and T4O are relatively effective in controlling the demodex mite population and the related symptoms, more research on the efficacy and drug delivery technology is needed in order to assess its potential as an alternative treatment with minimal side-effect profile, low toxicity and low risk of demodEx resistance.

Antimicrobial efficacy of liposome‐encapsulated silver ions and tea tree oil against Pseudomonas aeruginosa, Staphylococcus aureus and Candida albicans
TLDR
Treatment of suspension cultures of Pseudomonas aeruginosa, Staphylococcus aureus and Candida albicans using liposome‐encapsulated TTO, Ag+ and TTO plus Ag+ in combination resulted in an enhanced loss of viability compared to treatment with individual agents.
Antimicrobial activity of clove and rosemary essential oils alone and in combination
TLDR
The time‐kill curves of clove and rosemary essential oils towards three strains showed clearly bactericidal and fungicidal processes of 1/2 × MIC, MIC, MBC and 2 × MIC.

The mode of antimicrobial action of the essential oil of Melaleuca alternifolia (tea tree oil)
TLDR
The ability of tea tree oil to disrupt the permeability barrier of cell membrane structures and the accompanying loss of chemiosmotic control is the most likely source of its lethal action at minimum inhibitory levels.
Potential application of plant essential oils at sub-lethal concentrations under extrinsic conditions that enhance their antimicrobial effectiveness against pathogenic bacteria
TLDR
Clove, oregano, bay and cinnamon essential oils were tested against Salmonella typhimurium, Escherichia coli, Bacillus cereus and Listeria innocua and it is suggested that EOs can be combined with NaCl at low concentrations overcome organoleptic effects in food and inhibit growth of pathogenic bacteria.
