A lab cannot possibly even come close to reproducing all the conditions or factors in the real world that could cause bacterial mutations.
We can't discount the possibility of *new-found strains* being erroneously perceived as newly *evolved* strains.
The point is that when studies are none in the lab, they start with one strain of bacteria. There is no source for an erroneously percieved strain. They are indeed new strains that did not exist before. The lab doesn't have to create conditions or factors that cause mutations, only selective pressure to select ones with the right RANDOM mutations. The conditions in the lab don't cause the mutations, selective pressure only causes mutations that allow the strain to survive to become prevalent in the population.
In nature, there are probably new strains coming out all the time due to random mutation and selective pressure. Man made biotics only increase the ability for mutations that give resistence to them to become dominant in a population.
