Table 4 : Average Amount of AIEC colonies that survived under
sequential therapy (Set A)
The AIEC bacteria that were treated via sequential therapy in set b were
not able to replicate nearly as well as the bacteria that were treated
via combination therapy. This is because during sequential therapy,
specifically in set b, select antibiotics in sequential order were able
to the destroy DNA of AIEC bacteria and prevent them from multiplying
(10). Set b was also found to be more effective than set a because since
the strong antibiotics were applied first, this eliminated most
bacterial colonies before they have a chance to evolve. This was a much
more effective method than the weak-strong treatment and yielded a much
lower number of surviving colonies.
