Identification of Candida dubliniensis among oral yeast isolates from an Italian population of human immunodeficiency virus-infected (HIV+) subjects
2002
Candida dubliniensis, an emerging oral pathogen, phenotypically resembles Candida albicans so closely that it is easily misidentified as such. The aim of the present study was to evaluate the usefulness of two phenotypic methods, growth at 45 degrees C and 2,3,5-triphenyltetrazolium chloride (TTC) reduction, for confirming presumptive identification of C. dubliniensis and C. albicans by colony color on CHROMagar Candida (CAC) medium. A combination of these methods was used to establish the prevalence of oral C. dubliniensis in an Italian population of 45 human immunodeficiency virus (HIV)-infected subjects. Twenty-two samples (48.9%) were positive for yeasts on CAC medium producing a total …
Carbohydrate assimilation profiles of the first Italian Candida dubliniensis clinical isolates recovered from an HIV-infected individual.
2001
A total of six Candida dubliniensis isolates were obtained during 1 year of monitoring by monthly swabs from the oral cavity of an asymptomatic human immunodeficiency virus-infected individual in Catania, Italy. To the authors' knowledge, this constitutes the first recovery of C. dubliniensis from a human in Italy. Our identification procedure was based on colony color on CHROMagar Candida and carbohydrate assimilation profiles obtained by two commercial systems: API ID 32C and API 20C AUX. Karyotyping by pulsed-field gel electrophoresis confirmed the phenotypic identification. The biocodes obtained with API 20C AUX and with API ID 32C were 6172134 and 7142140015, respectively, for all six …

Aislamiento de Candida dubliniensis en un adolescente con estomatitis protésica
2005
Objetivos: Utilizar varios métodos que permiten la diferenciación entre Candida albicans y Candida dubliniensis en un intento de conocer si C. dubliniensis puede ser aislada de la cavidad oral de adolescentes con prótesis ortopédicas orales. Materiales y métodos: Se aislaron 12 cepas de género Candida procedentes de mucosa palatina y de soporte de prótesis de 12 pacientes adolescentes portadores de prótesis ortopédicas orales. Para la diferenciación entre C. albicans y C. dubliniensis se utilizaron varias pruebas fenotípicas (la asimilación de fuentes de carbono con el método comercial ID 32C, el crecimiento en agar glucosado de Sabouraud a 45 ºC, la producción abundante de clamidosporas en…
