From the above information, let us categorize the given 8 microbes as a,b,c,d,e,f,g and h, respectively.
a -Streptococcus aureus
b -Streptococcus pyrogens
c -Mycoplasma pneumoniae
d -Clostridiumbotulinm
e -Escherichia coli
f -Pseudomonas aeruginosa
g -Campylobacter fetus
h -Listeria monocytogens
Note:After microscopical experiments if it is Gram negative comma shaped bacteria ,we can directly confirm it is g, i.e Campylobacter fetus
Table of diagnostic tests and bacterial characteristics "+" means positive for that test or characteristic "-"...

The chart below describes the biochemical reactions of six
different Gram-positive bacteria for the indicated tests. Following
the example your instructor presented at the beginning of the lab
period, construct a dichotomous key to identify the six bacteria
listed below. IMPORTANT: do not start your key with the same test
your instructor used to start the example in class. Draw your chart
by hand on the next page titled “Dichotomous Key.” Your key should
include all the tests needed to...

A: The Disturbing Discharge You are working in a gynecologist's office. Your first patient is a 19-year old woman who complains that she has experienced vaginal itching and a frothy greenish-white vaginal discharge with a strong odor for the past several days. When you examine her, you observe inflammation of the genital region. When you ask your patient if she is sexually active, she tells you she has had two sexual partners in the past 4 months. You swab the...
5. Why are simple stains able to "stick” to bacteria? Explain the chemical properties of the stain and bacteria surface. 3-Preparation of Bacterial Smears and Simple Stains Introduction Microbial cultures are handled using aseptic technique. Aseptie technique is a set of procedures used to minimize contamination of materials by microorganisms from the environment, and to minimize the spread of cultures around the laboratory. In this experiment, you will be using an inoculating loop to transfer bacteria from a culture tube...
