Another Method: Destroying the Enemy by
There are many
other micro-organisms that live within the human body
which cause us no harm. What are these organisms that
continue with their own life without doing us any harm,
and what is their purpose in living within our body?
groups of micro-organisms, which are gathered in certain
parts of the body, are called the normal microbial flora
of the body. They do no damage and even have some benefits
for the human body.
These micro-organisms provide
external support for the defence army against microbes.
They benefit the body by preventing foreign microbes
from settling in it, because the entry of any microbe
into the body is a threat to their own housing site.
Since they do not want to be displaced by the invaders,
they fight a fierce battle against them. We can think
of these micro-organisms as "professional soldiers"
fighting for the body. They try to protect the site
they live in for their own benefit. In so doing, they
complement the fully equipped army in our body.
How do these "professional soldiers"
settle in our bodies?
The human embryo has met no enemy
during the gestation period in the mother's womb. Following
the birth of the child, it makes contact with the environment,
and numerous microbes are introduced to the child through
the intake of food and by way of the respiratory tract.
Some of these microbes die right away, while others
are discharged before having the chance to settle down
in the body. Some, however, settle in various parts
of the body such as the skin, skin ridges, mouth, nose,
eyes, upper respiratory tract, digestive tract, and
genital organs. These microbes form permanent colonies
at these locations and constitute the microbial flora
of the human body.
