The Microbiome, Bacteria
& More!
Microorganisms and other related science stuff!
Overview
Our
Relationship to microorganisms… The
Human Microbiome…you are more microbe
then humane!
Distinguishable
Uses
The
YAY
features (prokaryotic)
of Bacteria
symbiotic relationships of human-bacteria.
SCIENCE!!
Project Description
There are millions of
microbes per square inch
on your body
Thousands of different species
on the skin alone
Some thrive on dry patches of
the elbow, others thrive in moist
environment of armpit
It is estimated that there are more
microbes in your intestine than there
are human cells in your body!
What is the Human Microbiome?
Microbe: tiny living organism, such as
bacterium, fungus, protozoan, or virus
Microbiome: collectively all the microbes in
the human body; a community of microbes
Biofilm: a community of microbes that live
together on a surface
Microbes in the Human Microbiome include
species from each major domain:
Archaebacteria
Bacteria
Fungi
Prokaryotic Cells = Bacteria!!!
Bacteria
have
no nucleus or
membrane
bound
organelles.
Bacteria
come
in a variety of
sizes and shapes
just like
eukaryotic cells.
When do we get our first bacteria?
As
a baby passes
through the birth
canal it is coated
with bacteria and
are included in
breast milk and
other bacteria.
You are never alone….

Each person is unique
and so is the microbial
communities in our
bodies!
There
are even
different microbial
communities on and
in different parts of our
bodies!
Microbes are normally found in and on the
human body
There are different habitats on
our bodies for different types
of microbial communities like:
On
our skin,
In
our mouths
In
our nose
In
our guts
Other
places etc. etc.
BUT WHAT DO THEY DO?!
 Bacteria
help to educate your
immune system
 Gut
flora assist with digestion
…metabolism... Even vitamin
production.
 Ward
off bad bacteria and
produce natural
antibiotics…fighting off infections
 Signaling
cells
Good Bacteria VS Bad Bacteria
“Bad” bacteria are traditionally
defined as pathogenic bacteria,
which means they may cause
infection, make us sick or, in
some cases, even kill us! Bad
bacteria come from external
influences such as food,
environmental toxins and even
the effects of stress on our
bodies.
Antibiotics and Antimicrobials
Antibiotics
Kills infectious bacteria
but also disrupts natural
flora.
Antimicrobial
Many products kill germs and bacteria to “reduce
infections”.
 Natural Exposure? What problems could arise?
Probiotics vs Antibiotics
Probiotics are the opposite of
antibiotics. Antibiotics kill
bacteria, while
probiotics are bacteria.
Probiotics help repopulate the
good bacteria in the gut—the
bacteria that keep you healthy.
Antibiotics Kill Bacteria and
Can Cause Stomach
Problems.
3 Types of Symbiotic Relationships
1.
Mutualism – Both the human host and bacteria
benefit. (Ex. E Coli in the Lg. Intestine)
2.
Parasitism- Only the bacteria benefit: Human
host harmed. (Ex Pathogenic Bacteria)
3.
Commensalism-Only the bacteria benefit:
Human host not harmed. (Unaffected)
Domestic/Commercial Use of Bacteria
Yoghurt,
milk, cheese
etc.
Beer & Wines
Vinegars
Pickles
Nail Polish Remover
Aquarium additives
Medical Uses of Bacteria
Medicines can be made by
specially-modified bacteria,
called transgenic bacteria.
These single-celled organisms
have foreign genes along side
their own DNA. They live and
reproduce like ordinary
bacteria, but they also do a
bit of extra duty, and produce
human proteins for medicines
and vaccines.
Bacteria and the Environment
Bioremediation is a waste
management technique that involves the use of
organisms to remove or
neutralize pollutants from contaminated site.
