Enzymatic and hemolytic activities of Candida dubliniensis strains.
Candida dubliniensis is an opportunistic yeast that has been recovered from several body sites in many populations; it is most often recovered from the oral cavities of human immunodeficiency virus-infected patients. Although extensive studies on epidemiology and phylogeny of C. dubliniensis have been performed, little is known about virulence factors such as exoenzymatic and hemolytic activiti...
متن کاملAdherence to buccal epithelial cells, enzymatic and hemolytic activities of Candida isolates from HIV-infected individuals.
Candida spp., along with other microorganisms are usually found in the normal flora of the human oral mucosa. However in HIV-infected individuals these yeasts can become opportunistic pathogens and lead to mucosal infections. The transformation from a harmless commensal to a virulent pathogen under conditions of dysfunctional host defense system is attributable to an extensive repertoire of sel...
متن کاملComparison of Switching and Biofilm Formation between MTL-Homozygous Strains of Candida albicans and Candida dubliniensis.
Candida albicans and Candida dubliniensis are highly related species that share the same main developmental programs. In C. albicans, it has been demonstrated that the biofilms formed by strains heterozygous and homozygous at the mating type locus (MTL) differ functionally, but studies rarely identify the MTL configuration. This becomes a particular problem in studies of C. dubliniensis, given ...
متن کاملDifferences in extracellular enzymatic activity between Candida dubliniensis and Candida albicans isolates.
Twenty-six Candida dubliniensis and 27 Candida albicans oral strains isolated from patients infected by the human immunodeficiency virus (HIV) were tested for germ tube production and 21 extracellular enzymatic activities. Assessment of the enzymatic profile was performed by using the API-ZYM commercial kit system (bioMerieux, France), which tests 19 different enzymes. Protease activity was exp...
متن کاملIn vitro activities of antifungal agents alone and in combination against fluconazole-susceptible and -resistant strains of Candida dubliniensis.
In the present study we used two groups of Candida dubliniensis strains: one containing fluconazole-susceptible clinical isolates and another containing fluconazole-resistant laboratory derivative from the former to examine the changes on susceptibility accompanying the development of resistance to fluconazole. Our findings confirmed the ability of C. dubliniensis isolates to become resistant t...
