Study of the Microbial Diversity of Outdoor Bioaerosols of Mexico City
Bioaerosols are defined as airborne dispersions of solid or liquid particles that contain whole or part of biological entities such as bacteria, viruses, dust mites, fungal hyphae or spores. The study and identification of airborne microorganisms in indoor and outdoor environments has received considerable attention in the last years in developed countries due to their potential to affect negatively animal and human health, especially in mega cities. However most of the studies in these cities are limited to the characterization of urban pollutant emission fluxes and ambient concentration. Although several methods of microbial characterization like flow cytometry claim to be faster and superior than the traditional culture and microscopy methods for Bioaerosol evaluation, they are still imprecise when the interest comes to determine the microbial community structure and identity all or selected members of the sample. In these cases an rDNA based fingerprinting method like DGGE is a suitable choice. The aim of this research work was to characterize the microbial diversity present in samples of Bioaerosol from Mexico City. Results obtained showed an interesting diversity in the composition of the airborne microbial population in samples. Organisms from the genera Bacilli, Lactobacilli, Planococcus, Pseudomonas, Acinetobacter, Pantotea and Enterobacter where identified.
