    Abstract:
    Candidiosis is a mycosis that is currently increasingly affecting the population in consequence of its frequency and the severity of its complications, especially among immunocompromised hosts. In this work, the in vitro anticandidal activities of two phenothiazines (PTZs), chlorpromazine (CPZ) and trifluoperazine (TFP), and their combinations with amphotericin B (AMB) were tested against 12 different Candida strains representing 12 species (Candida albicans, Candida glabrata, Candida guillermondii, Candida inconspicua, Candida krusei, Candida lusitaniae, Candida lypolitica, Candida norvegica, Candida parapsilosis, Candida pulcherrima, Candida tropicalis and Candida zeylanoides). When used alone, both tested PTZs exerted antifungal effects against these strains. In their combinations, these PTZs and AMB mainly acted antagonistically at higher concentrations, but additively and synergistically at lower concentrations as concerns the clinically most important species (C. albicans and C. parapsilosis). For C. albicans, only synergistic interactions were revealed between CPZ and AMB. Synergistic, additive or no interactions were demonstrated between the investigated compounds for the most PTZ-susceptible (C. glabrata to TFP and C. krusei to CPZ) and insusceptible strains (C. glabrata to CPZ and C. lypolitica to TFP).
