azole-resistant Candida glabrata
Case report-Subjects-Three cases are described oflong-standing vaginal candidosis due to Candida glabrata. These had failed to respond to local and systemic antifungals. In each case the infecting strain appeared resistant to a range of azole drugs in vitro. Clinical course-Case one-This patient recovered following prolonged treatment with oral itraconazole in combination with oral and vaginal ...
متن کاملMolecular biological characterization of an azole-resistant Candida glabrata isolate.
Two isolates of Candida glabrata, one susceptible and one resistant to azole antifungals, were previously shown to differ in quantity and activity of the cytochrome P-450 14alpha-lanosterol demethylase which is the target for azole antifungals. The resistant isolate also had a lower intracellular level of fluconazole, but not of ketoconazole or itraconazole, than the susceptible isolate. In the...
متن کاملNucleotide substitutions in the Candida albicans ERG11 gene of azole-susceptible and azole-resistant clinical isolates.
One of the mechanisms of Candida albicans resistance to azole drugs used in antifungal therapy relies on increased expression and presence of point mutations in the ERG11 gene that encodes sterol 14α demethylase (14DM), an enzyme which is the primary target for the azole class of antifungals. The aim of the study was to analyze nucleotide substitutions in the Candida albicans ERG11 gene of azol...
متن کاملExpression of Efflux Pumps and Fatty Acid Activator One Genes in Azole Resistant Candida Glabrata Isolated From Immunocompromised Patients.
Acquired azole resistance in opportunistic fungi causes severe clinical problems in immunosuppressed individuals. This study investigated the molecular mechanisms of azole resistance in clinical isolates of Candida glabrata. Six unmatched strains were obtained from an epidemiological survey of candidiasis in immunocompromised hosts that included azole and amphotericin B susceptible and azole re...
متن کاملOccurrence of killer Candida glabrata clinical isolates
In this work we characterized the occurrence of killer activity in 64 Candida glabrata clinical isolates under different conditions. We found that only 6.25 % of the clinical isolates tested were positive for killer activity against a Saccharomyces cerevisiae W303 sensitive strain. Sensitivity of killer activity to different values of pH and temperatures was analyzed. We found that the killer a...
