Does our body create its own bacteria?

Answer 1

First, you need to consider what bacteria are. Once you've established that, you can consider whether or not your body can make bacteria.

We can start with the cell theory of life. The cell theory states that all life is composed of 1 or more cells and that all cells must originate from pre-existing cells.

Bacteria are a certain type of cell called prokaryotic. This means that bacterial cells do not have a separate compartment for their DNA. Contrast this to our own cells, which have a nuclear compartment for our DNA and are defined as eukaryotic. Prokaryotic means "before nucleus," and eukaryotic means "true nucleus."

Both prokaryotic and eukaryotic cells are living things.

Prokaryotic cells can only produce and be produced by other prokaryotic cells. Likewise, eukaryotic cells can only produce and be produced by other eukaryotic cells.

Since we are eukaryotic, we can only produce more of our own human eukaryotic cells. We cannot manufacture bacterial cells.

All of the bacteria that live in and on us come from our external environment.
