Ward’s Antibiotic
Resistance Kit
Compare Bacteria With and
Without Natural Resistance
Using two types of common, naturally
occurring, nonpathogenic bacteria,
students grow a lawn of each with
penicillin-impregnated discs on each
plate. The bacteria with natural resistance
should completely cover the
plate with growth, while the bacteria
without resistance will show a zone of
inhibition (a ring of no growth around
the disc). It comes with Escherichia coli
and Staphylococcus epidermidis tube cultures, materials for five lab groups, and
instructions. Note: Includes perishable materials. Please specify delivery date.
