> The only reason a bacteria will be less prone to washing away is if its useful for our skin in some way and has a symbiotic relationship with it.
Why do you think that ability to produce glue that's resistant to soapy water might only come from some form of symbiosis with the host?
> In any case, is there any evidence that we do have some skin microbiota that sticks even after good soap wash?
Do you think soap producers wouldn't claim that their soap removes 100% of bacteria instead of 99,99% if it wasn't provably false?
And what do you mean by good soap wash? Do you know how surgeons wash their hands? And yet they still cover those thoroughly washed hands with sterile gloves.
Infection rates double if there is a hole in a glove despite the thorough washing. I think you may consider it to be evidence.
