Answer: This is an extremely drug resistant bacteria that must have inherited genes against this drug resistant from a parent bacteria that was exposed to the drug or substance. The parent bacteria went through a mutation to survive this environmental pressure and transferred that gene or mutation to its offspring.

Through natural selection and horizontal gene transfer this bacteria is able to survive in the presence of a molecule that is supposed to kill it and has developed extreme resistance against.
