When do we use a needle and when do we use a loop?
Give this one a try later!
LOOP is for LIQUID, NEEDLE is for solid
Were your cultures consistent in appearance? How could you confirm your culture
was a pure culture? Where during the process of aseptic transfers could contaminants
, be introduced?

Yes, the cultures were consistent in appearance. The culture was pure
because they had the same color, transparency, elevation and edge. The
test tube cap is a source of contamination as well as not sterilizing the loop
before and after transfer
Describe and draw the growth of your organism on the Petri dish; be sure to include
the organism' names

Micrococcus luteus; yellow color with smooth, buttery texture
In the case file, the organism responsible for the patient's death is a normal member
of the human microbiota. How do you explain it causing the death of this patient?
Give this one a try later!
It was introduced into an area where the microbiota is not found. The
microbiota is normally found in the oral cavity and intestinal tract
Jeffrey, Jane's partner, inoculated a tryptone broth tube with E. coli. When he
examined his broth tube during the next lab period, there was no growth at all. What
could have gone wrong with his experiment?
