Caracterización de histoplasma capsulatum en muestras biológicas mediante pruebas de laboratorio

Abstract

Histoplasma capsulatum is a dimorphic fungus found in the feces of birds and bats that infects people through its conidia when they are aspirated and the number of them will depend on the severity of the disease caused by the fungus, histoplasmosis. It usually infects people with HIV. Its yeasts are found in the liver, lungs, bronchoalveolar lavages, bone marrow, skin. Objective: To characterize Histoplasma capsulatum through bibliographic review for the identification of the fungus in biological samples. Method: The present investigation is based on a descriptive study, which was carried out through an exhaustive search for information in scientific articles that help to solve the question and provide a solution to the practical case. Conclusion: Histoplasma capsulatum was identified as small yeasts of 1 to 2 micrometers in diameter and for this, histological staining is required, associating its mycelial characteristic in the culture because it is a dimorphic fungus.
