Tea tree oil, an important oil from the Australian plant Melaleuca alternifolia, has broad antimicrobial exercise and is integrated into a various vary of pharmaceutical and beauty merchandise (2, 3). Blackwell (1) described a affected person with typical indicators and signs of bacterial vaginosis (BV) who handled herself with tea tree oil vaginal pessaries. After remedy, the affected person was symptom free and the vaginal flora comprised predominantly gram-positive bacilli. It was recommended that using tea tree oil for the remedy of BV be additional assessed. Due to this fact, the purpose of this examine was to guage the actions of tea tree oil towards lactobacilli and a variety of organisms related to BV.

Reference (n = 9) and saved medical (n = 24) isolates had been obtained from the tradition collections of the Western Australian Centre for Pathology and Medical Analysis (PathCentre) and the Division of Microbiology at The College of Western Australia. Current medical isolates (n = 69) had been recovered from vaginal swabs submitted to PathCentre and recognized in response to the Wadsworth Anaerobic Bacteriology Guide (5). Three isolates of Gardnerella vaginalis had been kindly offered by Helen MacDonald of the Ladies’s and Kids’s Hospital, Adelaide, Australia.

Organisms had been examined towards doubling dilutions of tea tree oil (batch 93/04, Australian Plantations Pty. Ltd., Wyrallah, Australia) ready in agar or broth medium. Bacteroides, Prevotella, fusobacteria, and anaerobic gram-positive cocci had been examined in supplemented brucella laked-blood agar (5), with 0.5% (vol/vol) Tween 20 added to boost oil solubility. G. vaginalis and Mobiluncus spp. had been examined in Columbia agar base supplemented with 1% Proteose Peptone 3 and 5% chocolatized sheep blood. Lactobacilli (n = 26) had been examined by the broth microdilution methodology utilizing de Man-Rogosa-Sharpe (MRS) broth (Unipath Ltd., Basingstoke, United Kingdom). Chosen BV isolates (n = 13) had been examined by a broth macrodilution methodology (5) utilizing mind coronary heart infusion broth (BHIB) supplemented with 1 μg of vitamin Okay and 5 μg of hemin per ml, with a remaining take a look at quantity of two ml. A remaining focus of 0.001% (vol/vol) Tween 80 was added to each MRS and supplemented BHIB, to boost oil solubility. Preparation of inocula, inoculation of susceptibility assessments, incubations, and willpower of MICs and/or MBCs had been carried out as described elsewhere (5).

Desk ​Table11 lists MIC knowledge obtained by the agar dilution assay. As well as, for 5 G. vaginalis isolates tea tree oil MICs had been 0.06%, and for 3 of the 4 Mobiluncus isolates the MICs had been 0.03%, with 0.06% for the fourth. By broth macrodilution, MICs for all six Bacteroides isolates had been 0.06%. The MBCs for 5 isolates had been 0.06%, whereas the MBC for the remaining isolate was 0.12%. MICs and MBCs for 2 Prevotella isolates had been 0.03%. The MICs for 4 of the 5 Peptostreptococcus anaerobius isolates had been 0.06%, with 0.03% for the fifth. MBCs had been 0.03% for one isolate, 0.06% for 3 isolates, and 0.12% for the remaining isolate. MICs for the lactobacilli ranged from 0.12 to 2.0% and the MIC at which 90% of isolates had been inhibited (MIC90) was 2.0%. MBCs for lactobacilli ranged from 0.25 to 2.0%, and the MBC90 was 2.0%.

These MIC knowledge are much like these obtained in earlier research which indicated that a wide range of anaerobic and cardio micro organism had been prone to tea tree oil (2-4). The info additionally present that each one lactobacilli examined had been appreciably extra immune to tea tree oil than organisms recognized to be related to BV, with no less than a twofold distinction in MIC90 outcomes. Due to this fact, the medical success reported by Blackwell (1) could also be due, partly, to the susceptibility of BV-associated organisms to tea tree oil and the relative resistance of commensal lactobacilli. This distinction in susceptibility could enable formulation of merchandise that may selectively kill or inhibit sure organisms whereas having a minimal impact on the commensal lactobacilli. Acceptable trials at the moment are urgently wanted to find out whether or not these theoretical advantages will translate into medical follow.
