Abstract
Oral candidiasis is a fungal infection mostly common in people infected with HIV and the recurrent episodes occur in patients with AIDS. Aiming at searching, a new and efficacious drug against resistant strains, the antifungal activity of essential oil from Melaleuca alternifolia at different concentrations was assessed on yeasts isolated from oral candidiasis. The experiment was performed by using agar diffusion
technique; and the antifungal effect was evaluated on the standard strains of Candida albicans ATCC 10231, Candida tropicalis ATCC 157, Candida glabrata ATCC 30070, Candida krusei ATCC 6258 and Candida dubliniensis ATCC 778 157, and on the isolated from the oral cavity of HIV positive pregnant women,
being seven C. albicans, one C. tropicalis, one C glabrata and one C. krusei. The essential oil was analyzed in quantities of 20 and 50 μL at 10-100% concentrations, ranging from 10 to 10%. All of the tested strains were susceptible to the M. alternifolia essential oil at concentrations of 70% and 50% in volumes of 20 μL and 50 μL, respectively. The antifungal activity of essential oil from M. alternifolia holds one´s attention in manufacturing new and effective drugs.
