Steve Moss asked the Naked Scientists:
   
For what reason(s) must you always complete a course of antibiotics?

What do you think?

Main reason: To be sure all bacteria are dead.
If you bring bacteria in contact with Antibiotics, but not in sufficient quantities or for a long enough period, there's a chance that there will be selection of the bacteria with a resistance for the taken Antibiotic.
Then, this one bacteria that underwent this selection might multiply in your body and next time, the Antibiotic you've taken before will not work anymore.

Yes, as Nizzle says, it is to ensure that all of the bacteria are killed and that none survive to build up and pass on a tolerance to the antibiotic, which would render it useless.
...And its claws are as big as cups, and for some reason it's got a tremendous fear of stamps! And Mrs Doyle was telling me it's got magnets on its tail, so if you're made out of metal it can attach itself to you! And instead of a mouth it's got four arses!
