Estudio de la micota ambiental de tres edificios de la universidad Santiago de Cali, Colombia

Abstract

The quantification of the environmental load in the indoors of the buildings (1, 3 and 4) of the University Santiago De Cali, Colombia and in their corresponding responses to the results to obtain a load value. A volumetric method and Dicloran Bengal chloramphenicol (DRBC) and CHROMagar Cándida culture media were used for sampling. The identification of the fungi was carried out based on macro and microscopic characteristics. Parallel to the sampling the relative humidity and temperature of each space studied was determined. This study was conducted for quarterly periods during twelve months (March 2018 to march 2019). In the study of environments of the three buildings was detected a total of 82393 colony forming units (CFU/m3) of which 60053 CFU/m3correspond to indoor environment. The results obtained showed that it was not possible to establish a correlation between the temperature and the CFU/m3 found inside the three buildings, but for the relative humidity in relation to building 4.The genera Cladosporium, Fusarium, Penicillium and Aspergillus were identified as the most prevalent allergenic fungi in this study. The results in the quantification revealed that the fungal burden exceeds the limits accepted for internal environments (500 CFU/m3) according to the World Health Organization (WHO).
