Isolation of from the Oral Cavity of Immunocompetent Young Adults from the North of Mexico.

UNLABELLED

The human oral cavity is normally colonized by microorganisms including bacteria, fungi, archaea, viruses and protozoa. The aim of this study was to determine the frequency of spp., in de oral cavity in a group of medical students from the north of Mexico. Oral sample were obtained from 240 healthy students. The specimens were analyzed by traditional microbiology cultures and DNA sequencing. spp., grew in Sabouraud dextrose agar from 57 samples and subsequently were isolated and phenotyped. The definitive identification to the species level was done by sequence analysis. The yeasts were identified as follow: 28 , 20 , 5 and 4 . Our findings revealed that 23.75% of the healthy population has a potential pathogen in their mouth. Surprisingly, is not the predominant yeast; instead other non- species are the colonizers of the oral cavity as normal microbiota. is considered an emerging opportunistic pathogen in immunosuppressive patients. This paper pretends to highlight the presence of this yeast in the oral cavity in immunocompetent young adults.
