Antifungal Susceptibility Profile In Vitro Fungal Air in a Hospital Environment

Abstract

Purpose: The aim of this study was to isolate and identify potentially patho-genic airborne fungi from Hospital das Clínicas Samuel Libânio in the city of Pouso Alegre-MG and evaluate their susceptibility to natural and industrial products. Methods: The air collection was performed by passive sedimenta-tion in the morning during the autumn and winter seasons. Petri dishes were open as the location of air conditioning. The isolates were subjected to patho-genicity test. The identification of the fungi was performed according to the macroscopic evaluation and micromorphology. Potentially pathogenic isolates were susceptibility tested by disc diffusion method. The agents used were insecticides and industrial cleaning products and essential oils of citronella plants, lemon grass, eucalyptus and Melaleuca extracted by steam distillation method. Results: We obtained a total of 356 fungal isolates. The inside door environments were 126 (35.39%) and the outside environments were 230 (64.6%) isolates. The 22 (6.18%) isolates from the inside and 25 (6.18%) outside the hospital showed pathogenic potential. This isolates were identified as
