“Photodynamic therapy (PDT) is a minimally invasive approach, in which a photosensitiser compound is activated by exposure to visible light. The activation of the sensitiser drug results in several chemical reactions, such as the production of oxygen reactive species and other reactive molecules, whose presence

in the biological site leads to the damage of target cells. Although PDT has been primarily developed to combat cancerous lesions, this therapy can be employed for the treatment of several conditions, including infectious diseases. learn more A wide range of microorganisms, including Gram positive and Gram negative bacteria, viruses, protozoa and fungi have demonstrated susceptibility to antimicrobial photodynamic therapy. This treatment might consist of an alternative to the management of fungal infections. Antifungal photodynamic therapy has been successfully employed against Candida albicans and other Candida species and also against dermatophytes. The strain-dependent antifungal effect selleck screening library and the influence of the biological medium are important issues to be considered. Besides, the choice of photosensitiser to be employed in PDT should consider the characteristics of the fungi and the medium to be treated, as

well as the depth of penetration of light into the skin. In the present review, the state-of-the-art of antifungal PDT is discussed and the photosensitiser characteristics are analysed. “
“Fifty-three soil samples were collected from various

sites L-NAME HCl in the vicinity of Vedanthangal Water Bird Sanctuary and screened for the presence of keratinophilic fungi using the hair baiting techniques for isolation. Twenty-eight isolates were recovered and identified by recognition of their macro- and micromorphological features. Seven species related to five genera were recorded viz. Auxarthron conjugatum (1.89%), Chrysosporium fluviale (3.77%), Chrysosporium indicum (20.75%), Chrysosporium tropicum (7.55%), Chrysosporium state of Ctenomyces serratus (5.66%), Gymnoascus petalosporus (1.89%) and Microsporum gypseum complex (11.32%). The study shows that migratory birds harbour a variety of keratinophiles and may be a potential source of transfer of these fungi from one location to another. “
“Candida albicans is the predominant causal agent of candidiasis. Its ability to form hyphae and biofilm has been suggested to be key virulence factors. In this study, we investigated the effect of major licorice compounds licochalcone A, glabridin and glycyrrhizic acid on growth, biofilm formation and yeast-hyphal transition of C. albicans. The synergistic effect of licorice compounds with the antifungal drug nystatin was also evaluated. Minimal inhibitory concentrations (MICs) for C.
