ABSTRACT
Objective: The aim of this work was to assess the antifungal and post-antifungal effects of chlorhexidine, fluconazole,chitosan and its combinations on virulence factors of Candida albicans. Study Design: Ten isolated strains of Candida albicans obtained from 10 patients with oral candidiasis and acollection strain of C. albicans were treated with antifungal agents in different concentrations or combinationsof them. Virulence factors analyzed were the cell surface hydrophobicity, the germinative tube development, the phospholipase activity and the post-antifungal effect of that exposure. Results: Virulence factors of the isolated strains obtained from patients together with the collection strain showed significant decreases with the different antifungal treatments, except for hydrophobicity and phospholipase activity.The development of germinative tube was the most sensitive factor to all the antifungal agents used. Untreated strains as well as the ones treated with antifungal agents showed a positive correlation among the virulence factorsanalyzed. No synergic effects arose from the combinations of the used drugs. Conclusions: C. albicans isolated strains from patients showed high phospholipase activity and germinative tubeproduction, which corroborates their capacity to infect the oral mucosa and the high prevalence of species. Asa whole, our results imply that short exposures to sub-inhibitory concentrations of the antifungal agents underanalysis, isolated or combined, can modulate the way virulence factors get manifested, thus decreasing their pathogenicity (AU)
