Can you tell me how e. coli reated to science?

I'm not sure what: you are wanting to know. Escherichia coli is a bacterium found predominantly in intestines of warm blooded animals including humans. It is not usually harmful in its body environment but can cause cause infections, commonly in the urinary tract or gut. It is transmitted by fecal contamination, so hand washing after a BM is important. Women particularly should wipe front to back after a BM.
