摘      要：Bacteria in the air present patterns in space and time produced by different sources and environmental *** studies have focused on the link between airborne pathogenic bacteria in densely populated cities,and the risk to the population’s *** associated with particulate matter(PM)were monitored from the air of Mexico City(Mexico).We employed a metagenomic approach to characterise bacteria using the 16S rRNA *** bacteria sampling was carried out in the north,centre,and south of Mexico City,with different urbanisation rates,during *** added to the particles were sampled using high-volume PM_(10) *** ascertain significant differences in bacterial diversity between zones and seasons,the Kruskal-Wallis,Wilcoxon tests were done on alpha diversity ***-three air samples were collected,and DNA was sequenced using next-generation *** results indicated that the bacterial phyla in the north and south of the city were Firmicutes,Cyanobacteria,Proteobacteria,and Actinobacteria,while in the central zone there were more *** were no differences in the alpha diversity indices between the sampled *** to the OTUs,the richness of bacteria was higher in the central *** diversity was higher in the rainy season than in the dry season;the Shannon index and the OTUs observed were higher in the central zone in the dry *** bacteria such as Kocuria,Paracoccus,and Micrococcus predominated in both seasonal times,while Staphylococcus,Corynebacterium,and Nocardioides were found during the rainy season,with a presence in the central zone.
