Chiroptera are not only important for their great terrestrial diversity, but also for playing ecological roles as prey and predator, arthropod suppression, soil fertility and nutrient distribution, and recycling (
ResumenIntroducción: Candida sp puede encontrarse como comensal en equilibrio en la cavidad bucal humana; pero, en la población pediátrica y adolescente con un sistema inmune inmaduro las condiciones de la levadura se tornarían favorables para su patogenia. Objetivo: Determinar la presencia de Candida albicans en secreción faríngea y nasal en alumnos de educación secundaria. Diseño: Estudio descriptivo transversal. Lugar: Instituto de Medicina Tropical, Universidad Nacional Mayor de San Marcos, Lima, Perú. Participantes: Alumnos del 4° (52) y 5° (50) años de secundaria. Intervenciones: En octubre del 2007, las muestras nasales y faríngeas de 102 estudiantes de 14 a 17 años fueron colectadas en medios de transporte y luego cultivadas en los laboratorios del Instituto de Medicina Tropical, en agar sabouraud y CHROMOagar Candida. Se identificó las colonias sospechosas de Candida sp mediante el estudio de clamiodoconidias, tubo germinativo y pruebas metabólicas. Principales medidas de resultados: Identificación de levaduras de Candida sp. Resultados: Se aisló levaduras del género Candida en 11 de los escolares (10,8%). El 36,4% de las levaduras presentó resistencia moderada al antimicótico fluconazol. Conclusiones: Es recomendable continuar con estudios de vigilancia epidemiológica sobre las levaduras de importancia médica en portadores nasofaríngeos, con el fin estar preparados ante eventuales cuadros infecciosos. Palabras clave: Candida albicans, escolares, fluconazol. Abstract Objective: To determine the presence of Candida albicans in throat and nasal secretion in high school students. Design: Crosssectional study. Setting: Institute of Tropical Medicine, Universidad Nacional Mayor de San Marcos, Lima, Peru. Participants: High school students from San Juan Macias School in Santa Anita, Lima, Peru. Interventions: Nasal and throat samples were collected from 102 14-17 year-old students. Samples were grown on sabouraud agar and Candida CHROMOagar and identified by chlamydospores study and metabolic tests. Main outcome measures: Identification of C. albicans yeast. Results: Candida yeast was isolated from 11 students (10.8%). A significant percentage of yeast (36.4%) developed moderate resistance to fluconazole. Conclusions: Continuous surveillance of medically important yeasts in nasopharyngeal carriers is suggested in order to be prepared for eventual infectious conditions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
