Lab Day 5

Lab Day 5

Results and Conclusions for Lab Day 4:
Selective and/or differentiation experiment:
Blood Agar: Negative (no hemolysis), therefore our unknown bacteria is Gamma-hemolytic

EMB plate: Negative,  therefore our unknown bacteria is gram-pos.

Mannitol Salt: Negative, therefore our unknown bacteria cannot tolerate 7.5%NaCl and is Non-pathoogenic.

MacConkey plate: Negative, therefore our unknown bacteria is gram-pos. and non-lactose fermenting.

PEA agar plate: Positive, therefore our unknown bacteria is gram-pos.

Antibiotics experiment:
Red
1. Neomycin-12mm, therefore it is resistant
2. Norobicin-14mm, therefore it is resistant
3. Penicillin-31mm, therefore it is sensitive
4. Streptomycin-16mm, therefore it is sensitive
Blue
1. Erythromycin-20mm, therefore it is intermediate
2. Tetracycline-30mm, therefore it is sensitive
3. Amoxocillin-25mm, therefore it is sensitive
