Electrophoretic protein patterns and numerical analysis of Candida albicans from the oral cavities of healthy children
The aim of this research was to evaluate the protein polymorphism degree among seventy-five C. albicans strains from healthy children oral cavities of five socioeconomic categories from eight schools (private and public) in Piracicaba city, São Paulo State, in order to identify C. albicans subspecie...
