Oxygen Kills Candida – Myth #7
I’d like to welcome you back today for another one in our series of Candida myth videos.
Today’s Candida myth is “Oxygen kills Candida.”
The best way to dispel this myth is just to look at the basic physiology of the human
intestinal tract. The small intestine is approximately 20 feet in length, and the large intestine
is approximately 5 feet in length. Within this 25-foot tube exists 100 trillion bacterial
cells. These 100 trillion cells outnumber human cells by a factor of ten to one. Within
these 100 trillion cells, we know that 95 to 99 percent of them are anaerobic bacteria.
Anaerobic bacteria live in an oxygen-deprived environment, and it takes an oxygen-deprived
environment to create the ecosystem of the digestive tract.
Aerobic bacteria, which are commonly found in the environment, live in an oxygen-rich
environment. The air around you is an example of an oxygen-rich environment, and the air
in outer space would be an example of an oxygen-deprived environment. When discussing bacteria, we
wanna understand that there are bacteria that are either obligate aerobes or anaerobes,
or they are facultative aerobes or anaerobes. Obligate aerobes are obligated to live in
an oxygen-rich environment. Facultative aerobes can live either in an oxygen-rich or an oxygen-deprived
environment. Now, this is true also for obligate anaerobes.
Obligate anaerobes are obligated to live in an oxygen-deprived environment; whereas, facultative
anaerobes can live in either an oxygen-rich or an oxygen-deprived environment. So when
we’re discussing Candida, it’s important to note that Candida is classified as a facultative
anaerobe. That means it can live in an oxygen-deprived environment, such as the intestinal tract
and much of the human tissues of the body, or it can live in an oxygen-rich environment,
such as the surface of your skin or tongue. An example of an aerobic fungal Candida infection
would be thrush or some type of fungal skin condition.
Most of the initial research that was done with Candida involved Candida in an aerobic
state, so most people are aware of thrush or fungal skin infections. And ask anybody
who has a thrush infection; this is a very difficult infection to get rid of. And many
times, fungal Candida skin infections are the same way. It wasn’t until later years
that they started to actually investigate Candida as a facultative anaerobe and looking
into anaerobic environments, such as the intestinal tract.
So from the basic physiology, we can see that Candida, as a facultative anaerobe, can live
either in an oxygen-rich environment or an oxygen-deprived environment. This alone dispels
the myth that oxygen kills Candida. If we take it further, we find that Candida is very
adaptive, and almost instantaneously adaptive, in its anaerobic environment in the digestive
tract. Some of our earlier videos demonstrate the
effects of white blood cells in trying to destroy Candida. When a white blood cell,
such as a macrophage or a neutrophil, consumes a bacteria – and we have videos that are
on our site that demonstrate this – you’ll see that within a few seconds, the bacteria
dissolves inside the white blood cell. © Copyright 2010-2011, All Rights Reserved,

consume Candida, the Candida survives. So it’s important to look at what’s happening
in a white blood cell. When a substance is consumed by a white blood
cell, the white blood cell forms a little sac around the bacteria, or the Candida, and
then, inside the white blood cell, there will be another sac that is filled with oxygen.
These two sacs will meet, the oxygen will be released into the sac containing the microorganism,
and it’ll cause dissolution, or dissolving of that organism, spontaneously. But when
you see videos of Candida being consumed by white blood cells, you see the Candida inside
the white blood cells accumulate more and more because the oxygen has no effect against
the Candida. Another place to look is back to the research.
Candida contains a molecule called a quorum-sensing molecule called farnesol. Farnesol enables
Candida to survive high levels of oxygen if it’s ever exposed to that within the digestive
tract. A quorum-sensing molecule like farnesol plays a role in determining whether Candida
becomes a yeast form or a fungal form, and that’s what quorum-sensing molecules do.
They have an effect on the genetics and how the genetics function inside the cells.
So based on our understanding of the physiology, based on what we know about Candida as a facultative
anaerobe, and based on what research studies continue to show us, it’s easy to see that
Candida is not affected by oxygen, and, in fact, seems to grow even hardier in an oxygen-rich
