tea and tree and oil

Abstract: This study investigates the in vitro activity of tea tree oil TTO against a range of wild strains of microorganisms isolated from clinical specimens of leg ulcers and pressure sores. The antimicrobial effectiveness of TTO is determined in terms of minimum inhibitory concentration MIC and minimum bactericidal concentration MBC or minimum fungicidal concentration MFC. The isolates include methicillin-resistant Staphylococcus aureus MRSA, S.

aureus, faecal streptococci, BETA-haemolytic streptococci, coagulasenegative staphylococci, Pseudomonas spp. and coliform bacilli.

Eleven Candida spp. isolates from skin and vaginal swabs also are tested.

Using an agar dilution assay, the MICs of TTO in 88 out of 90 isolates was 0.5-1.0% vv, whilst with P. aeruginosa it was >2% vv.

A broth microdilution method was used to determine MIC and minimum cidal concentration MCC of 80 isolates. In 64 isolates, TTO produced an inhibitory and cidal effect at 3% and 4% vv, respectively.

S. aureus and Candida spp.

were the most susceptible to TTO, with MICs and MBCs of 0.5% and 1%, respectively. P.

aeruginosa and the faecal streptococci isolates, with MICs and MBCs of >8%, were resistant to TTO. Key words: Tea tree oil.

Clinical isolates. Minimum inhibitory concentration.

Minimum cidal concentration. Introduction Increasing interest in naturally occurring, protective pounds is the result of growing disillusionment with certain aspects of orthodox biomedicine, such as the increase in allergic reactions, the toxic effects of certain antibiotics, and the increase in resistance of microorganisms to antibiotics.2 Tea tree oil TTO is a frequently used topical preparation,3 derived from the Australian plant Melaleuca alternifolia and reported to have antibacterial, antiviral and antifungal activity.
