Using penicillin-impregnated discs on two plates, students grow one lawn each of two common, naturally occurring pathogen bacteria.
- Students Compare Bacteria with and without Natural Resistance
- Two Common Bacteria Included
- Material for Five Lab Groups Included
- Instructions Included
- Penicillin-Impregnated Discs on Each Plate
The bacteria with natural resistance covers the entire plate with growth.
The bacteria without resistance shows a zone of inhibition (a ring of no growth around the disc).
Ordering information: It includes Escherichia coli and Staphylococcus epidermidis tube cultures, material for five lab groups, and instructions.
