Inhibitory effect of essential oils against Trichosporon ovoides causing Piedra Hair Infection

Abstract

Piedra, is an asymptomatic fungal infection of the hair shaft, resulting in the formation of nodules of different hardness on the infected hair. The infection also known as Trichomycosis nodularis is a superficial fungal infection arising from the pathogen being restricted to the stratum corneum with little or no tissue reaction. The nodules are a concretion of hyphae and fruiting bodies of the fungus. Two varieties of Piedra may be seen, Black Piedra and White Piedra. The fungus Trichosporon ovoides is involved in the occurrence of both types of Piedras. The purpose of this study was to examine the effectiveness of selected essential oils for the control of growth of the fungus and to determine whether the antifungal effect was due to the major compounds of the oils. Two screening methods viz. Agar well diffusion assay and Minimum Inhibitory Concentration were adopted for the study. MIC and MFC were determined by tube dilution

Ocimum tenuiflorum L. and Ocimum basilicum L., two spices of Lamiaceae family with bioactive essential oils

“…thyrsiflora are able to inhibit the growth of Debariomyces hansenii and Candida albicans (Avetisyan et al, 2017). The growth of Trichosporon ovoides is inhibited by the presence of O. basilicum essential oil (Saxena et al, 2012), in addition, the oil is also able to inhibit the growth of other dermatophytic fungi (Bozin et al, 2006;Nardoni et al, 2015). Similarly, the essential oil of O. basilicum inhibits the growth of A. niger (Fitsiou et al, 2016;Shirazi et al, 2014) and C. albicans (López et al, 2005;Shirazi et al, 2014).…”

“…Some studies have addressed the antifungal properties of O. tenuiflorum (Balakumar et al, 2011;H Gopalkrishna et al, 2016;Joshi, 2013;Kalagatur et al, 2015;Amber Khan et al, 2010;Khan et al, 2014aKhan et al, , 2014bRao et al, 2011;Zomorodian et al, 2015) andO. basilicum (Abou El-Soud et al, 2015;Avetisyan et al, 2017;Cardoso et al, 2016;Císarová et al, 2016;Fitsiou et al, 2016;Joshi, 2014;López et al, 2005;Nardoni et al, 2015;Pozzatti et al, 2008;Saxena et al, 2012;Shirazi et al, 2014;Soares et al, 2015). However, few discuss the effect on virulence factors with only scarce reports on inhibition of biofilm formation by O. basilicum (Cardoso et al, 2016).…”

Efficacy of citronella and eucalyptus oils against Musca domestica, Cimex lectularius and Pediculus humanus

“…The differences may be due to difference in test models (Aedes mosquito) used for the evaluation of repellent potential of these oils. It is important to investigate scientifically those plants which have been used in traditional medicines as potential sources of novel antimicrobial compounds [33]. As a result, an integrated vector management (IVM) is a sustainable approach to manage insects that combines biological, cultural, physical and chemical tools in a way that minimizes economic, health and environmental risks [34].…”

Review of the Chemical Composition, Pharmacological Effects, Pharmacokinetics, and Quality Control of Boswellia carterii

“…An antimicrobial effect of B. carterii for bacteria (Gram-positive and Gram-negative) and fungi was associated with its essential oils and its smoke [ 68 , 69 , 89 , 90 ].…”
