O objetivo deste artigo foi caracterizar os aspectos biológicos de cepas de C. albicans orais em crianças com síndrome de Down. Estas leveduras foram analisadas quanto aos seus aspectos macromorfológicos e enzimáticos e foram testadas quanto a sua suscetibilidade in vitro a drogas antifúngicas, usando a microdiluição em caldo para a determinação da concentração inibitória mínima (CIM). A morfotipagem revelou que todos os isolados de C. albicans orais de crianças com síndrome de Down induziram à formação de franjas independente do tamanho, enquanto o grupo controle teve franjas menores. Todas as cepas de C. albicans orais produziram proteinase, mas aquelas com atividade fosfolipidolítica mostraram maior capacidade enzimática no grupo teste. A suscetibilidade in vitro mostrou que todos os isolados de C. albicans orais foram sensíveis a drogas empregadas.

The aim of this article is to characterize the biological aspects of oral strains of C. albicans in children with Down's syndrome. These yeasts were analyzed as to their macromorphological and enzymatic aspects and were tested as to their in vitro susceptibility to antifungal drugs using broth microdilution to determine the minimum inhibitory concentration (MIC). The morphotyping revealed that all oral C. albicans isolates from children with Down's syndrome promoted the formation of fringes regardless of size, while the control group presented smaller fringes. All oral C. albicans strains produced proteinase, but those with phospholipolytic activity showed greater enzyme capacity in the test group. In vitro susceptibility showed that all oral C. albicans isolates were sensitive to the drugs used.
