Today we checked all of our plates that we made yesterday!
First off, we checked Lauren’s strep plate. Our plate showed
alpha hemolysis (partial) so that means that her throat is negative for strep
throat.
Then, Christina’s nose… negative for staph auereus because
there was no yellow growth. 1 in 3 people do have staph auereus in their
nose.
Our plate that we spread our unknown bacteria over and
placed disks of antibiotics on it showed that our bacteria is : Non sensitive
to Penicillin, Intermediate to Tetracycline, Resistant to Erythromycin,
Susceptible (Positive) to Chloramphenicol.
The Manitol plate of our bacteria was negative because there
was no discoloration, which means there is no S. aureus.
The blood agar plate of our bacteria had partial alpha
hemolysis due to the green hint of growth.
Next we evaluated all of our bacteria results to find out
what unknown bacteria we had! We followed a flow chart depicted below:
We believe that we have Escherichia
Coli (E Coli), but we are performing one more test to make sure! We are
going to do a bacteria plate on an EMB plate to double check.
