Effect of Leptospermum petersonii volatiles on Aspergillus fumigatus hyphae. Unlike L. petersonii oil treatment, however, C. albicans requires ≥ 3 h exposure to these compounds to show an increase in PI permeability [53,55]. Product categories. Conversely, 10 × MIC100 of L. petersonii (0.5% v/v) resulted in complete inhibition of A. fumigatus within 1 h and 1 × MIC100 (0.05% v/v) caused complete inhibition within 3 h. Morphological examination of C. albicans cells following exposure to L. petersonii oil showed that the treated cells displayed morphological changes similar to those seen following exposure to membrane disrupting drugs or ATP synthase inhibiting drugs such as amphotericin B and polygoidal [36–38]. Wor1-regulated ferroxidases contribute to pigment formation in opaque cells of Candida albicans. If L. petersonii does target the fungal cell membrane, rapid lysis of spheroplasts would be expected to occur post-exposure [51–53] and in fact, only 10 min of exposure to 10 × MIC100 of the oil resulted in a rapid cell lysis. The leaves are gathered from the wild for use as a medicine and a tea and to extract an essential oil. Price £154.20 (£185.04 incl. 285-372-4. Propidium iodide uptake: percentage viability of Candida albicans following exposure to Leptospermum petersonii essential oil. 1 Cosmetics Ingredients containing LEPTOSPERMUM PETERSONII OIL. Membrane damaging compounds such as amphotericin B, nystatin, natamycin, chitosan and ethanol are known to induce cellular leakage of 260 nm absorbing material within 1 h of exposure of susceptible fungi [47–49]. The susceptibility of spheroplasts to L. petersonii oil was also examined. Agar plates were inoculated with a 6mm fungal plug taken from the periphery of an established colony and incubated at 25°C until the colony radius reached 20 mm. Plant essential oils comprise many bioactive components that are biodegradable and selective in their activity, thereby their application would be environmentally acceptable and compatible with an IPM program (Isman 2000, Koul et al. Aspergillus test isolates were maintained on Sabouraud dextrose agar (SAB: Oxoid) or malt extract agar plates, with and without 5% glucose (Oxoid). in 1918 (Brophy et al., 2000) and described to have a “pleasant lemon scented odour” due to its principle components citronellal and citral (Penfold et al., 1948, Brophy et al., 2000).

Candida albicans (oral isolate) was provided by S. Wheeler, Charles Sturt University. When L. petersonii oil vapour was allowed to absorb onto agar prior to fungal inoculation, A. fumigatus was the most susceptible while A. flavus was noted to be the least susceptible (Table 2). These results would again imply that the oil is damaging the cell membrane similar to compounds like echinocandin, amphotericin and ibuprofen. Clinical isolates of Aspergillus niger, A. fumigatus, A. flavus, A. terreus and A. nidulans were provided by D. Ellis, Adelaide. All assays were performed in triplicate on separate occasions.
