Ward’s Basic
Microbiological
Techniques
Lab Activity
Learn How to Identify
Bacteria Using Several
Different Staining
Procedures
By employing culturing and
staining techniques including
sterile transfer; streak plating;
and simple, Gram, and endospore
staining, students identify
the included “unknown” bacteria.
These procedures also familiarize students with sterile technique and preparation
of microscope slides. Tube cultures: Bacillus cereus and Escherichia coli.
You will also get enough materials for six setups, a teacher’s guide, and student
copymaster. Note: Coupon included for perishable materials. Redeem by mail,
fax, phone, or e-mail.

Ward’s Gram
Stain Kit
Easy and Fast with
No Chemical Mixing
Required
The simplified staining technique
allows you to stain your
cultures to identify Grampositive
and Gram-negative
bacteria, which is an important
initial method of identifying
bacteria. The kit contains all
necessary staining materials,
including Gram’s iodine solution, crystal violet stain, safranin O stain, ethyl alcohol,
and instructions.

Staining and
Bacterial
Morphology
Lab Activity
Classify Bacteria Using
Common Staining
Technique
The way bacteria respond to
Gram staining and their cellular
morphology are two
important steps in identifying
them. This lab activity includes
four cultures that can be stained to illustrate the differences among them.
Tube cultures: Aquaspirillum serpens, Bacillus cereus, Escherichia coli, and
Staphylococcus epidermidis. It comes with teacher’s manual and materials for
30 students. Note: Coupon included for perishable materials. Redeem by mail,
fax, phone, or e-mail.

Ward’s Identification of Bacteria:
Gram Staining Lab Activity
Introduce Gram Staining Method and
Use of Dichotomous Key
Students utilize two important methods of identifying bacteria with the materials
in this lab activity. After observing basic characteristics of a colony, students
Gram stain the specimens and observe the reaction under a microscope, then
determine what type of bacteria it is by following the included dichotomous
key. Freeze-dried cultures: Bacillus megaterium, B. subtilis, Escherichia coli, K.
rhizophila, K. rosea, Lactococcus lactis, Sarcina aurantiaca, Serratia marcescens,
Staphylococcus epidermidis, and Streptomyces violaceus. The kit includes
enough materials for six lab groups, teacher’s guide, and student copymaster. It
is also available in a demonstration size. Note: Coupon included for perishable
materials. Redeem by mail, fax, phone, or e-mail.

Ward’s Gram
Stain Bacterial
Suspension Kit
Culture Common
Gram-Positive and
Gram-Negative
Bacteria
Use this handy kit in conjunction
with our Gram Stain Kit
for a complete exercise that
covers culturing to Gramstaining
identification. With
this kit, students culture both
a Gram-positive rod and a
Gram-negative rod in preparation for staining. It comes with Bacillus megaterium
and Escherichia coli freeze-dried cultures, culture materials, and instructions.
Note: Coupon included for perishable materials. Redeem by mail, fax,
