March 10, 2010
When we initially started the bacteria antibiotic experiment on February 10, 2010 our team
selected e-coli and Rifampicin (Rb5) to find out the level of resistance e-coli would build
towards this antibiotic. When we first checked our agar dish on February 15, 2010 we noticed
two circles for the zone of inhibition the small circle was 1.5 cm and the medium circle was 3.00
cm. Two days later when we checked it again the small circle had stayed the same at 1.5 cm but
the medium circle was 3.02 cm. The changes were minimal during that first week. Week two
however on February 24, 2010 the small circle had become smaller it was now 1.3 cm and the
