Could Germ Toxicity Be an Environmental Effect?

Listeria becomes nasty when starved of oxygen, reported EurekAlert.  “Limiting oxygen produces bacteria up to 100 times more invasive than similar bacteria grown with ample oxygen supplies.”

Could this imply that a world with different atmospheric or soil conditions could have been less prone to disease?  Could the bacteria we fear most have been placid or even beneficial in such an environment?
    One instance doesn’t make the case, but this surprising finding is food for thought.  Pasteurize before consuming.
