They are important so that one can manipulate objects without infecting the worker or contaminating the environment.
By improperly handling of the bacteria, or by doing any or all steps of the aseptic technique incorrectly.
Short answer is Koch's postulates. Long answer you can't ascribe any scientific data you may gather to a bunch of bacteria on a plate or in a culture, as you won't know which of the bacteria gave you the result you observed. So if you are trying to figure out which bacteria causes a disease, inoculating a mix of bacteria won't tell you which one causes the disease. Isolating each one using aseptic technique and then inoculating individually and finding the disease in one animal will tell you which bacteria caused to disease.
The adjectives are partly synonymous, but something that is antiseptic kills bacteria, while something aseptic is "surgically clean or sterile."
The terms sterile and aseptic mean the same thing. And you are supposed to use a sterile/aseptic technique. From what I have read, many visiting nurses do not do that if they are from the doctors' office. But they do it in the hospital. It is always best to do this using a technique that will not infect the patient.

to warm the tube and create warm air convection currents up and away from the opening, to prevent the entrance of dust particles upon which contaminating bacteria reside.
