Avirulence of Candida albicans auxotrophic mutants in a rat model of oropharyngeal candidiasis.
The virulence of Candida albicans strain SC5413 and two isogenic derivatives have been investigated in a rat model of oropharyngeal candidiasis. The results demonstrate that both mutant strains are avirulent in this animal model while the parental strain readily initiates infection. Avirulence is not related to altered growth characteristics or the inability of the strains to undergo yeast-to-h...
متن کاملAvirulence of Candida albicans CaHK1 mutants in a murine model of hematogenously disseminated candidiasis.
Deletion of both alleles of the Candida albicans CaHK1 gene, which causes cells to flocculate when grown at pH 7.5, a pH comparable to that of mammalian blood, abolishes the ability of the yeast to establish a successful infection in a murine model of hematogenously disseminated candidiasis. Within 72 h all mice inoculated with the parental C. albicans strain had died. The mice infected with ei...
متن کاملNew model of oropharyngeal candidiasis in mice.
We established a straightforward murine model of oropharyngeal candidiasis. Mice were immunosuppressed with cortisone acetate, anesthetized, and then inoculated by placing cotton wool balls saturated with Candida albicans sublingually for 2 h. A prolonged, reproducible infection was induced. This model may be useful for antifungal screening or pathogenesis studies.
متن کاملOropharyngeal candidiasis in children with lymphohematopoietic malignancies in Mashhad, Iran
Background and Purpose: Over the past years, the role of fungi as a cause of nosocomial infections in hospitalized patients has been accentuated. Candida species constitute an important group of fungi causing diseases in immunocompromised patients. Oropharyngeal candidiasis continues to be a prevalent infection in immunodeficient patients. In this study, we aimed to determine the incidence of o...
متن کاملOropharyngeal candidiasis: a new treatment option.
In this issue of Clinical Infectious Diseases, Vazquez et al. [1] demonstrate in a well-conceived and well-conducted multicenter trial that posaconazole is equivalent in efficacy to fluconazole in the treatment of oropharyngeal candidiasis in HIV-infected patients. Patients given posaconazole also experienced fewer clinical relapses of oro-pharyngeal candidiasis than did patients given fluconaz...
