Photodynamic inactivation of four Candida species induced by photogem®

Abstract: This study evaluated the in vitro susceptibility of C. albicans, C. dubliniensis, C. tropicalis and C. krusei to photodynamic therapy (PDT) induced by Photogem®and light emitted diode (LED). Suspensions of each Candida strain were treated with three photosensitizer (PS) concentrations (10, 25 and 50 mg/L) and exposed to 18, 25.5 and 37.5 J/cm2 LED light fluences (λ ~ 455 nm). Control suspensions were treated only with PS concentrations, only exposed to the LED light fluences or not exposed to LED light or PS. … Show more

“…Nonetheless, non-albicans species, such as Candida glabrata, Candida tropicalis and Candida krusei, are also frequently associated with the development of infections. 25 Candida albicans sometimes exists in a mixture with other microbial species in this environment. 26 The virulence of C. albicans may be influenced not only by its own properties but also by its interactions with cohabitating oral microorganisms.…”

“…[34][35][36] The PDT inactivation experiments with Candida albicans were also performed to evaluate the effect of these PSs in a fungus cell, as it has a different cell wall when compared to bacteria. 37 We evaluated the PDT activity of both PSs at 20 and 30 μg mL Previous studies have reported the inactivation of Candida albicans with PDT using Photogem, 37 which presents the same complete inhibition with 50 μg mL −1 and a fluence of…”
