Red LED and demodex -- Just a thought   Message List  
Reply | Forward Message #91558 of 105078 |
Re: Red LED and demodex -- Just a thought

Did a little more research. Unfortunately without more background knowledge it’s
only speculation, but seems to be heading somewhere.

There is a gram negative bacteria found within the Demodex Mite called Bacillus
Oleronius.


The following is an article on LLLT and Gram Negative Bacteria. It mentions two
other types of Bacteria, being the Gram Negative Pseudomonas aeruginosa and the
Gram Positive Staphylococcus aureus.

They classify the difference as follows. Gram-negative bacteria are those that
do not retain crystal violet dye in the Gram staining protocol. Gram-positive
bacteria will retain the dark blue dye after an alcohol wash, whereas
Gram-negative bacteria do not. In a Gram stain test, a counterstain is added
after the crystal violet, which colors all Gram-negative bacteria a red or pink
color. The test itself is useful in classifying two distinctly different types
of bacteria based on structural differences in their cell walls.

Here is a quote…

“All energy densities of Ar ion laser showed a proliferative effect on
Pseudomonas aeruginosa and inhibitory effect on Staphylococcus aureus.
Similarly, SHG Nd:YAG and He-Ne lasers with chosen energy densities were again
proliferating for Pseudomonas aeruginosa and inhibitory for Staphylococcus
aureus“

http://www.springerlink.com/content/e072158g52487462/

This shows that LLLT definitely has an affect on Gram-Negative/Positive
bacteria.

Unfortunately you have to purcahse the article to see it in its entirety. If you
look at the google search though it mentions something about Gram negative
Bacteria with higher amounts of porphyrins, so it gives a teaser to possibly
releasing some information there.

http://www.google.com.au/search?hl=en&q=gram-negative+bacteria+respiratory+chain\
+porphyrin&meta=



This article mentions Bacillus, Porphyrin and respiratory chain but there was
soo much medical jargon it was hard to put it all together. Maybe Dan could
decipher this one for us if he has a spare minute?

This article from the Rosacea Archives relates a possible cause to Bacillus
Oleronius also.

Hmm, All I can add is that LLLT definitely has an affect on bacteria. But for
Bacillus Oleronius specifically though, I am unsure.

Hi Matt,

Thanks for your contribution to the discussion on this topic, which was of
course rather more detailed than the snippet above. ;)

I wonder if anyone else might like to take up the challenge and locate a study
with this information? You never know, someone might have a bit of time on their
hands and want to demonstrate their superior abilities with search engines. No
harm in cautious optimism, is there? :)

Kind regards,

Aurelia
