<span>When a body's host defenses are overwhelmed by contaminate, we start seeing biological responses to the invading bacteria. We may notice redness, swelling, oozing, pus, foul odor or warmth at the site of the wound. The host may also have an systemic fever, delirium or other responses when overwhelmed with bacteria.</span>
If we put a plastic bag over a branch of a tree, it should fill with the water vapor that the tree is releasing. If there is enough water vapor in the bag, it will condense into the liquid form of water, and we will be able to see it.
