There it would live, feeding off me, even earning its keep by keeping disease organisms, infections, and the like in check.

There are also biological controls, such as disease organisms that attack particular insect species.

Historically, down through the centuries, they've already tried a number of times to use disease organisms against us.

Some disease organisms, such as that for Tuberculosis, are difficult to sample from patients and slow to be grown in the laboratory.

There's some kind of disease organism all through its tissues.

These in turn would cause disease organisms to evolve new strains that were resistant to them.

If there are any disease organisms around, they're probably terrestrial ones, and the antibiotics should deal with them.

Their blood was tested, found to be free of disease organisms, and sent out for donation.

This in turn reduces the bodily functions which are under attack from the disease organism.

The problem isn't just the direct ability of disease organisms to enter the wound, although that plays a part.
