Abstract
HERNANDEZ-VELANDIA, David Ricardo and LIZARAZO-FORERO, Luz Marina. Aerobiological cetermination and comparison in three archives of the Empresa de Energia de Boyacá, Tunja (Colombia). Salud, Barranquilla [online]. 2015, vol.31, n.3, pp.537-547. ISSN 0120-5552. https://doi.org/10.14482/sun.31.3.5311.
In indoor and outdoor environments there great quantities of particles suspended in the air, they are the atmospheric aerosol. Between particles of biological origin are bacteria, fungal spores, algae, viruses, protozoa, pollen grains. Many researchers believe that fungi are indicators of the level of bio-pollution and are associated with nonspecific clinical symptoms in stays indoors or sick building syndrome Objective: Therefore, the purpose of this study was to determine the variations in the composition and concentration of the agents aerobiological present in three archives the Boyacá Power Company (EBSA), which could be causing respiratory allergies personnel working in these areas Materials and methods: A gravimetric method was used to perform the microbiological sampling of the air using potato dextrose agar, and agar nutrient, recording temperature and humidity data during each sampling, and collected dust samples for the cultivation of fungi and mites. Also surveyed workers in order to record respiratory symptoms suggestive and sampled the nostrils Results: We isolated an average 470.2 UFC/m3 of microorganisms in the three archives sampled. 29 genera were identified among bacteria, fungi and yeasts, and one non identified structure of fungi, prevalence the more diversity in fungal forms. The predominant fungal genera were Cladosporium, Mucor, Penicillium and Alternaria and to a lesser proportion yeast forms, mainly Rhodotorula genera . Among the bacteria, the most abundant genera corresponded to Pseudomonas, Neisseria, and Staphylococcus. In the samples nostrils were isolated the genera Penicillium, Cladosporium, Aspergillus, Mucor and Alternaria. Not observed mites in the analysis the dust samples. No statistically significant correlation was found between mean colony forming units with temperature and relative humidity. Conclusions: The significant presence of fungi and bacteria in the environment and in nostrils are able to affect the health of working in the archives and special genera of fungi that may have important implications because of the potential increase in the release of allergens of their spores and pathogenicity in immunocompromised individuals.
