Reply to comment by PanickedPoodle in How our microbiome is shaped by family, friends, and even neighbors. Study of the gut and mouth microbiomes of thousands of people from around the world raises the possibility that diseases linked to microbiome dysfunction, including cancer, diabetes, and obesity, could be partly transmissible. by MistWeaver80

bacteria aren't battling though?? most microbes produce signaling molecules dependent on their environment and may shift their chemical output dependant on other microbes present. but it's not all out war all the time. it's just a bunch of little organisms excreting chemicals because substrates were available. we do contain colonies though

Bacteria produce antibiotics as a defense mechanism against neighboring microbes to secure their patch, so it’s a kind of all out chemical war for supremacy because they evolve so quickly.
