Antimicrobial from soaps promotes bacteria buildup in human noses
AMERICAN SOCIETY FOR MICROBIOLOGY

SHARE PRINT E-MAIL
An antimicrobial agent found in common household soaps, shampoos and toothpastes may be finding its way inside human noses where it promotes the colonization of Staphylococcus aureus bacteria and could predispose some people to infection. Researchers at the University of Michigan report their findings this week in a study published in mBio®, the online open-access journal of the American Society for Microbiology.

Triclosan, a man-made compound used in a range of antibacterial personal care products such as soaps, toothpastes, kitchen surfaces, clothes and medical equipment, was found in nasal passages of 41% of adults sampled. A higher proportion of subjects with triclosan also had S. aureus colonization. S. aureus could promote infection in some populations such as people undergoing surgery.

New class of antibiotic found in dirt could prove resistant to resistance

by Rachel Feltman


That's the promise of a study published Wednesday in Nature. But the antibiotic, called Teixobactin, is still a couple years away from human trials, and at least four years away from your medicine cabinet. And unfortunately, it doesn't treat some of the world's nastiest bugs. But it could still make a huge impact on health.

Along with his colleagues and the help of a biotech start-up called NovaBiotic Pharmaceuticals, Northeastern University professor Kim Lewis tapped into a largely unexplored treasure trove of new antimicrobials: The dirt.

Dirt from a grassy field in Maine, to be specific.

Most microbiologists only ever work with around 1 percent of microbes -- the ones that will grow politely in the lab. But the rest refuse to grow on traditional growth media, like petri dishes. But there are potential antibiotics all over the world being created by plants, fungi, and microorganisms. Lewis and his colleagues sandwiched soil between two semi-permeable membranes, effectively tricking soil microbes into growing in a "natural" environment that was actually a lab culture.

Among the 10,000 organisms and 25 antibiotics they grew in this new type of culturing method is Teixobactin. It successfully obliterated MRSA and drug-resistant TB in cell cultures and in mice, and did so without any signs that the bacteria might become resistant to it.


The world needs new antibiotics, and several new classes of them -- distinguished by unique chemistry and new methods of action against the microbes they fight -- are in the research pipeline. But because antibiotics are expensive to develop and don't make much money (after all, over-prescribing simply speeds up the formation of bacterial resistance), true innovation comes rarely. If Teixobactin makes it to the market, it could be the first new class of antibiotic in decades.

Joint Pain, From the Gut

Scientists don't know what causes rheumatoid arthritis, but many suspect that the microbiome—the bacteria that live in our gastrointesntial tracts—may be to blame.


DAVID KOHNJAN 12 2015,

Doctors aren’t entirely sure what triggers rheumatoid arthritis, a disease in which the body turns on itself to attack the joints, but an emerging body of research is focusing on a potential culprit: the bacteria that live in our intestines.

Several recent studies have found intriguing links between gut microbes, rheumatoid arthritis, and other diseases in which the body’s immune system goes awry and attacks its own tissue.

A study published in 2013 by Jose Scher, a rheumatologist at New York University, found that people with rheumatoid arthritis were much more likely to have a bug called Prevotella copri in their intestines than people that did not have the disease. In another study published in October, Scher found that patients with psoriatic arthritis, another kind of autoimmune joint disease, had significantly lower levels of other types of intestinal bacteria.


[quote In fact, these bacteria have a powerful vested interest in controlling how our bodies respond to interlopers. Blaser and others say that it appears that many of the bugs that live inside us have thrived by modulating the immune system to avoid being recognized—and attacked—as invaders; in essence, these organisms train immune cells not to be trigger-happy. A microbiome with the wrong sorts of bugs, or the wrong ratio of bugs—a situation known as dysbiosis—may unbalance this immune system, causing immune cells to assault not only bacteria, but also the body itself.

Microbes are especially influential in the gut, which houses two-thirds of the body’s immune cells. As the pathway for digestion, the gastrointestinal tract must deal with a constant stream of food-related foreign microbes, which must be monitored and, if they are harmful, destroyed. To do this, our intestines have developed an extensive immune system, whose effects reach far beyond the gut. Immune cells in the gut seem to be able to activate inflammatory cells throughout the body, including in joints.]

[/quote]
Scher puts more faith in modifying the microbiome through diet. He notes that some patients with rheumatoid arthritis have benefitted from cutting out meat, or adopting a Mediterranean diet (high in fish, olive oil, and vegetables, and low in meat and saturated fat), though scientists don’t know exactly why this helps. In a separate study, Finnish researchers found that a vegan diet changed the gut microbiome, and that this change was linked to an improvement in arthritis symptoms.

Amid the Murk of ‘Gut Flora,’ Vitamin D Receptor Emerges as a Key Player

Now scientists have found that the vitamin D receptor is a key player amid the gut bacteria – what scientists refer to matter-of-factly as the “gut flora” – helping to govern their activity, responding to their cues, and sometimes countering their presence. The work was published online recently in the American Journal of Pathology.

The findings deliver a new lead to scientists investigating how bacteria might play a role in the development of inflammatory bowel diseases such as Crohn’s disease or ulceractive colitis. The work complements studies suggesting that Salmonella infection can increase the risk of inflammatory bowel disease.


“Vitamin D deficiency is a known factor in the pathology of inflammatory bowel disease and colon cancer,” said microbiologist Jun Sun, Ph.D., of the University of Rochester Medical Center, “but there have been very few reports about how bacteria might play a role by targeting the vitamin D receptor. Our work suggests one possible mechanism, by working through the vitamin D receptor, a sensor and regulator for the majority of functions of vitamin D.”

Sun specializes in the actions of bacteria in the body and how their interactions within the body contribute to disease. She has shown that bacteria often found in the human intestine affect molecular signals known to contribute to inflammatory response and cell growth.

Antibiotics give rise to new communities of harmful bacteria
Date:

University of North Carolina at Chapel Hill
Summary:
Most people have taken an antibiotic to treat a bacterial infection. Now researchers reveal that the way we often think about antibiotics -- as straightforward killing machines -- needs to be revised. The work not only adds a new dimension to how we treat infections, but also might change our understanding of why bacteria produce antibiotics in the first place.

Widely Used Food Additive in Processed Foods May Cause Obesity

Catherine GriffinFirst Posted: Feb 26, 2015 06:59 AM EST

We all know that we should be careful about what we eat. But did you know that a widely used food additive may actually promote obesity? Scientists have found that emulsifiers, which are added to most processed foods to aid texture and extend shelf life, can promote colitis, obesity and metabolic syndrome.
Like Us on Facebook

But how exactly do emulsifiers do this? It all has to do with how they alter gut bacteria. "Gut microbiota" refers to the diverse population of 100 trillion bacteria that inhabit our intestinal tracts. When gut microbiota are disturbed, a person can develop inflammatory bowel disease (IBD) and metabolic syndrome. IBD, which includes Crohn's disease and ulcerative colitis, affects millions of people. Metabolic syndrome is a group of very common obesity-related disorders that can lead to type-2 diabetes, cardiovascular and/or liver diseases.
Emulsifiers have been shown to promote bacterial translocation across epithelial cells. In order to see if emulsifiers might affect gut microbiota to promote these inflammatory diseases, they turned to mice.[color=#FF0000]


polysorbate 80 and carboxymethylcellulsose

Is common food additive to blame for rising rates of bowel disease?
Melissa Healy

processed foods, promotes inflammatory bowel disease and a cluster of obesity-related diseases known as metabolic syndrome, and may have contributed to the sharp rise in these conditions over the last three decades, says a new study conducted on rats.

The emulsifiers carboxymethylcellulose, often referred to as cellulose gum, and polysorbate 80, also known as Tween 80, add bulk to foods and keep sauces smooth and frozen confections from separating. They plump up fast-food shakes, keep bottled salad dressings creamy, and prevent ice cream from dissolving into an unsightly soup when left out.


They're also used extensively in pharmaceuticals, to improve the consistency of gel capsules, to make pills come apart in the stomach, and to keep medication suspended in fluids.

But when fed to rats in volumes that mimic their widespread consumption in humans, both emulsifiers induced low-grade inflammation, increased weight gain and fat deposition, caused worrisome changes in metabolic function, and changed the mix of bacteria that colonized their digestive tracts, the authors reported.

.


In rats, the consumption of the two emulsifiers appeared to administer a one-two punch to the gut. The detergent-like molecules were found to erode the mucous membrane that lines the gut and provides a buffer between the delicate epithelial cells of the intestinal surface and the garden of microorganisms that flourish there.



http://en.wikipedia.org/wiki/Polysorbate_80

"In Europe and America, people eat about 100 mg of polysorbate 80 in foods per day on average.[9] Influenza vaccines contain 25 μg of polysorbate 80 per dose.[7]"

Hi Wellness Coach,

I posted the Dr. Stephanie Seneff material on GMOs and glyphosate on page two and three of this thread. A disagreement about her theories broke out. If you would like to take that up again, please start your own thread.
Thanks for your contribution.

Upsetting the Bugs in Our Belly
Why would PPIs make the digestive tract below the stomach more vulnerable to damage? The answer appears to be in the bacteria living in the small intestine. Acid-suppressing drugs change the ecology of the gut.

The bugs in our belly are supposed to live in harmony. PPIs apparently disturb the balance of different types of bacteria, reducing the protection they normally provide to the intestinal lining. This worsens the damage caused by pain relievers.

Scientists believe that stomach acid normally kills off swallowed bacteria. By reducing acid levels in the stomach, the digestive tract is exposed to germs that would not normally survive. Several serious GI infections have been associated with PPI therapy, including the hard-to-treat germ C. diff (Expert Review of Clinical Pharmacology, Jul., 2013).

Another complication of bacterial overgrowth in the intestines is pneumonia. Regular use of PPIs has been linked to lung infections, especially in older people (Drugs & Aging, Jan. 2015).

Viruses Lurking in Gut May Contribute to Disease
Scientists have found novel viruses associated with Crohn's disease and ulcerative colitis.


The People's Pharmacy January 29, 2015 Default

Changes in the microbiome have been liked to a range of health conditions, including autoimmune diseases, allergy and even obesity. Inflammatory bowel disease seems to be associated with reduced diversity in the bacteria of the gut.

Now scientists have found evidence that viruses also play a role. A study of patients with Crohn’s disease and ulcerative colitis turned up DNA from previously unknown viruses that will warrant more research. Because some of these viruses are bacteriophages that attack bacteria, they might be responsible for the decreased diversity of bacteria in the colon in these conditions. It is unknown at this point how such viruses might colonize the digestive tract or how they could possibly be brought under control.

Study: Environment trumps genetics in shaping immune system


Associated Press By LAURAN NEERGAARD
January 15, 2015

[quote]When the researchers gave flu vaccine to participating twins, they found no sign that genetics determined how many flu-fighting antibodies were produced.

Most intriguing, the researchers found infection with a virus so common that most adults unknowingly carry it had a dramatic effect. Cytomegalovirus, or CMV, is dangerous to those with weak immune systems but harmless for most people, and prior research has shown it can rev up parts of a healthy immune system. Sure enough, the Stanford team examined 16 pairs of identical twins where only one had CMV, and found big differences in nearly 60 percent of the components studied.

Does that mean we should try to prime the immune system, rather than working so hard to avoid germy situations?

"I'm a strong believer in the power of dirt," Davis said with a laugh, but this study actually can't offer health advice.

"This just says the environment plays a huge role in shaping what your immune system looks like," he explained.[/quote]

http://www.askdoctork.com/are-poop-pill ... 1503217594

Now there’s an easier way to deliver the dose: poop pills. Researchers at Harvard-affiliated Massachusetts General Hospital have used capsules containing frozen fecal extracts from healthy people to successfully treat diarrhea caused by C. diff.

Disgusting as it sounds, the donor feces are processed so only bacteria remains in the pill. The pill that is swallowed is clean and odorless. It is, essentially, a probiotic pill. And its protective gel cover does not dissolve until it is deep in the digestive tract.

Hopefully, the clean and odorless poop pill will prove as effective as the original ways of delivering good bacteria into the gut. They weren’t pretty, but they worked.


instead of fecal transplant there is poop pills.
the wonders of modern medicine :eek: :lol:

Could Fixing Gut Bacteria Help Cure Autism?
By Peter R-

After news of a father improving his son's autism symptoms with antibiotics went viral, a new study has shown a link between gut bacteria and autism.


According to Fox News, the study involving 45,000 Norwegian children showed that infants with autism were two and half times more likely to experience gastrointestinal problems during both early and late infanthood.


The study comes after news of antibiotics improving autism symptoms surfaced.John Rodakis' son showed was able to make eye-contact and showed speech improvements after a course of amoxicillin prescribed for throat infection.


Rodakis' search for an explanation led him to many parents who prescribed antibiotics to their autistic children routinely, to bring improvements. He also met Dr. Richard Frye who heads the Autism Research Program at Arkansas Children's Hospital Research Institute.

Summary:
Can the consumption of fatty foods change your behavior and your brain? High-fat diets have long been known to increase the risk for medical problems, including heart disease and stroke, but there is growing concern that diets high in fat might also increase the risk for depression and other psychiatric disorders. A new study raises the possibility that a high-fat diet produces changes in health and behavior, in part, by changing the mix of bacteria in the gut, also known as the gut microbiome.
