Why do we use urban microbiome to study microbes? Urban microbiomes have an abundance of microbes. So, there's more microbia diversity found in cities than other microbiomes A variety of species richness is found in just a single microbial community of a city. Also, since cities keep changing, microbial habitats in cities also evolve as microbes keep mutating Too see if there's any change in these microbial communities over time like if there's an increase in the number of bacteria or species richness, we can use microbes from these communities Urban microbiomes also serve as a reservoir for human pathogens which is a significant aspect in human life. So we can use microbes from these communities to get a better insight about disease & pathogenicity or virulence & how to target them All of the above
