I AM TRYING TO IDENTIFY THIS UNKNOWN.
IMAGE 1 HAS TWO PICTURE OF CATALASE TEST AND BLOOD AGAR TEST.
I believe it is one of the following:
1) S. pyo.
2)S. agal .
3)S.pneu.
4)E. faecalis
5)S. aureus
6)S epi.
7)S. sapro.
8)M. luteus
Please let me know which test will i need out of the table to justify your reason of picking up the unknown and also how that test justifies it? what characteristics of that test made you pick the unknown?
In product testing, no colonies appeared.
Interpretation:
Rationale:
Why is Muller Hinton Agar (MHA) ideal for antibiotic susceptibility testing
