Abstract
Human oral cavity is normally colonized for microorganisms including bacteria, fungi, archaea, viruses and protozoa. The aim of this study was to determine the frequency of Candida albicans in de oral cavity in a group of medicine students from the north of Mexico. 240 oral samples from healthy students were analyzed by traditional microbiology cultures and DNA sequencing. 57 samples grew in media cultures. Sequence analysis identified the yeast as follow: 28 Clavispora lusitaniae, 20 Candida albicans, 5 Pichia kudriavzevii and 4 Candida parapsilosis. Our finding revealed that 23.75% of healthy population has a potential pathogen in its mouth. Surprisingly Candida albicans is not the predominant yeast, instead of others non-Candida species are the colonizers of the oral cavity in immunocompetent individuals. Oral cavity is colonized by potential pathogen yeast being Clavispora lusitaniae, Candida albicans, Pichia kudriavzevii and Candida parapsilosis.
