2. We live among a
huge number of
different
microorganisms.
They live in soil,
water, our mucous
membranes and in
ourselves
3. Single-celled organisms
that can quickly multiply.
One bacterium in just 10
hours can escalate to 1
billion bacteria! They can
survive on almost any
surface in any climate of
the Earth.
4. For the survival of the
bacteria obtain nutrients
from the environment. In
some cases this environment
is the human body. Bacteria
can reproduce outside or
inside the body, causing
infection and causing pain
in throat, dental caries,
pneumonia, ear infections,
etc.
5. Viruses by their structure are
simpler than bacteria and are
usually not even considered
living organisms. They are
like bacteria clone themselves
and multiply very quickly.
Viruses can only survive at
the expense of the host cell in
another organism. So they are
constantly in search of the
object (human or animal) for
later infection
6. The infected cell loses the
ability to function
normally and is forced to
synthesize viral proteins
and create more clones of
the virus has infected her.
After that the virus causes
the host cell to release all
viral particles to infect
other cells, thereby begins
to develop a particular
disease
7. The human body
contains about 2-3 kg of
bacteria
In the human intestine
from 300 to 1000
species of bacteria.
They help to digest
carbohydrates,
synthesize vitamins,
displace pathogenic
bacteria, etc.
8. During a cough or
sneeze the bacteria
can spread to a
distance of a meter
and land on the
surface, which can
be transmitted to
humans within three
days
9. The average mobile
phone, headphone and
microphone contain up
to 1,400 bacteria
Keep the restaurant
menu away from the
bowl, germs can linger
on it for 18 hours
10. Our skin loses at least 10
million cells every day.
Some of them with hands
transferred to surrounding
us, with whom we are in
contact daily (beds,
remotes, phones, doors
etc.) Just imagine: if you
touch one of these things,
and then put your fingers
in your mouth, you will
literally eat someone else's
dead skin
11. Conventional computer
mouse is three times
dirtier than the toilet
seat
96% doorway rugs
contain traces of fecal
bacteria that is
transferred into the
house on shoes
12. Office Desk with which
you work, are home to
about 20,000 bacteria
per 6 square
centimeters. Workplace
400 times more germs
than the toilet
Flu viruses, once on
banknotes can live for
up to 17 days
13. Thousands of years
people have used lactic
acid bacteria for the
production of cheese,
yogurt, kefir, vinegar,
and pickling Developed
methodology for using
plant pathogenic
bacteria as a safe
herbicide,
entomopathogenic
instead of insecticides
14. In agriculture use of
bacterial fertilizers
Bacteria are used
extensively in scientific
research in molecular
biology, genetics,
genetic engineering and
biochemistry
15. A promising direction is
the enrichment of ores
by sulphide-oxidizing
bacteria, purification of
bacteria contaminated
by oil products or
xenobiotics soil and
water
16. Bacteria and viruses are always present in our lives.
They bring harm and benefit. Personal hygiene and
healthy lifestyle will largely help to be friends with
them
