What’s happening: Typically, the percent of the highly resistant bacteria
(dimes and quarters) will increase while the less resistant ones decrease in
percentage. This is exactly what happens in real life if you don’t take all the
antibiotic. The bacteria that are hardest to kill stay and reproduce. This
makes it harder to cure the disease caused by the bacteria. If you had gone
through all the cards to begin with, you would have killed all the bacteria for
sure. Now one deck won’t do it. To avoid needing more medication, or
stronger medication, later on, the best thing to do is take all the antibiotic
the first time around.
