Last week biologists announced that several studies have solidified that fact that most cases of bad breath are caused by bacteria. Shocking? Not for anyone who understands the Marshall pathogenesis for chronic disease in which nearly all conditions can be attributed to the presence of L-form bacteria, biofilm bacteria, or other persistent forms of bacteria (collectively called the Th1 pathogens).

The culprit behind bad breath – Solobacterium moorei, which uses the tongue as a base on which to brew its halitosis-provoking fatty acids and malodorous compounds.

Two studies helped researchers confirm the findings. One, by the Buffalo School of Dental Medicine, probed 21 people with chronic bad breath and 36 without and found S. moorei in every patient that had halitosis. S. moorei was found in four of the comparison group, and while they were not yet polluting the air with foul emissions, all had periodontitis, an infection of the gums that can also lead to chronically bad breath. The biologists presented their findings at the annual meeting of the American Association for Dental Research in Dallas.

A previous study of of eight subjects with halitosis and five without found that S. moorei was “always found in patients with halitosis and never in patients who did not have the problem”. Dr. Violet I. Haraszthy, who participated in both studies, told Reuters Health “A number of other studies have also found this bacterium in halitosis patients.”

Haraszthy admits that “not much is known about this particular organism”, although Buffalo School of Dental Medicine student Betsy Clark concluded, “As we identify and find out more about the bacteria that cause bad breath, we can develop treatments to reduce their numbers in the mouth.”

Little does she know that such a treatment already exists. Patients on the Marshall Protocol report bad breath as a symptom of immunopathology. Odds are they effectively kill S. moorei and probably other bacteria yet to be detected that contribute to a foul smell from the mouth. After all, while the Buffalo researchers are content with the popular “one bacteria causes one condition” hypotheses, biomedical researcher Trevor Marshall’s work has confirmed that a diverse microbiota of bacteria are generally behind one affliction. When horizontal gene transfer is factored into the equation, it becomes increasingly obvious that an illness or condition is rarely caused by a single pathogen. Biofilms, which are often made up of over 30 or 40 species of bacteria, are common in the mouth, and can no doubt harbor pathogens besides S. mooreithat also contribute to bad breath.

I find it interesting that mainstream researchers have little problem implicating bacteria in conditions that affect the mouth. Perhaps it’s because of the fact that bacteria have been recognized as a cause of cavities for decades. Also, companies intent on creating products that might endow people with brighter smiles have spent enough money on research to realize that the “goo” that often covers teeth is made up of bacterial biofilms. But tell the same researchers that bacterial biofilms and persistent pathogens may also be causing infections in other areas of the body and they often respond with skepticism.
