- ÍtemSolo MetadatosDiversidad de levaduras cultivables que colonizan ambientes extremos domésticos en los andes ecuatorianos(Universidad Católica de Cuenca., 2023) Ortega Arana, Grecia Marcela; Zamora García, María Elissa; 0301785127; 0106649403; Yarzábal Rodriguez, Luis AndrésIntroduction: Within domestic environments, there are habitats that present unfavorable (extreme) conditions for the growth and development of various microorganisms, both pathogenic and non-pathogenic. Moreover, a group of extremophilic microorganisms is capable of multiplying in these extreme conditions. General Objective: To determine the composition of culturable yeast communities that colonize extreme domestic environments. Methodology: Yeasts were isolated from extreme domestic environments using Sabouraud Dextrose medium. The isolates were characterized morphologically, physiologically, and biochemically. It was also evaluated the expression of different virulence factors. Molecular techniques were used to identify the species to which they belong. Results: One hundred one microbial strains were isolated from five departments. From these, twelve yeasts that express different virulence factors were selected, including the production of hemolysins, proteases, and the ability to penetrate agar-based medium. The strains belong to ten species, with the genus Candida being the most frequent, followed by the genus Rhodotorula. Conclusion: The extreme domestic environments of homes in the city of Cuenca, particularly dishwashers, are colonized by potentially pathogenic yeasts.
