Gut Microbes Benefit Pregnancy

More and more science points out how critical and essential the intestinal flora (microbiome) is for health in the body. We are “Super-organisms.” The current point of view is that we consist of host cells (human cells) and support cells (bacteria, parasites, viruses, yeasts, fungi, etc.). Over thousands of years, we have co-evolved into a cohesive and co-dependent unit, where the presence and health of all the parts (human and non-human alike) constitutes the health of the whole. This recent research article demonstrates how the intestinal flora, or gut microbiota, play a regulatory role in creating a healthy pregnancy.

Hydrochloric Acid and Health

Hydrcochloric acid (HCL) is produced in the stomach to aid in activating digestion of foods and protection of the intestinal flora. Excess stomach acid (HCL) has traditionally been treated as a result of low HCL levels that creates cycles of over- and under-production. With the advent of direct-to-consumer marketing by pharmaceutical companies, the public was entrained to believe that this was purely an excess HCL problem that needed to be suppressed with antacids, leaving behind the science, physiology, and wisdom of the body.

Tryptophan Reduces Intestinal Inflammation

It’s always nice to see good research that helps to clarify simple principles that demonstrate what effectively works and doesn’t work for our bodies. Researchers from Japan, Switzerlan, Germany, Austria, and the Netherlands have discovered the effectiveness of the natural amino acid, Tryptophan in controlling inflammation of the intestinal tract. Such inflammation is associated with malnutrition, diarrhea, Crohn’s, IBS, IBD, and Colitis – http://www.sciencedaily.com/releases/2012/07/120725132133.htm

More than one billion people in poor countries are starving, and malnutrition remains a major problem even in rich countries, making it a leading cause of death in the world. For over a hundred years, doctors have known that a lack of protein in the diet or low levels of amino acids, the building blocks of proteins, can lead to symptoms like diarrhoea, inflamed intestines and other immune system disorders, which weaken the body and can be fatal. However, the molecular mechanism which explains how malnutrition causes such severe symptoms has been largely unexplored.

Now a research group led by Josef Penninger, the director of the Institute of Molecular Biotechnology (IMBA) in Vienna, Austria, in cooperation with Philip Rosenstiel, University of Kiel, Germany, has found a molecular explanation for the increased susceptibility to intestinal inflammation in malnutrition.  The researchers were studying an enzyme which helps to control blood pressure, kidney failure in diabetes, heart failure and lung injury, called the Angiotensin Converting Enzyme 2, or ACE2.  This enzyme was identified as the key receptor for SARS virus infections, but the researchers also discovered an entirely new function.  ACE2 controls the way our intestines take in amino acids from our food, via amino acid transporters, and in particular the uptake of the essential amino acid tryptophan.

Too little tryptophan alters our natural immune system, which changes the types of bacteria which can live in our bowels and guts, leading to higher sensitivity and eventually diarrhoea and inflamed intestines.  Increasing the intake of tryptophan in their diet provided relief for mice suffering from intestinal inflammation. The mixture of bacteria returned to normal, the inflammation died down, and the mice also became less susceptible to new attacks.

“The research shows how the food we eat can directly change the good bacteria in our intestines to bad bacteria and so influence our health”, says Thomas Perlot, the first author of the study. “Our results might also explain nutritional effects that have been known for centuries and provide a molecular link between malnutrition and the bacteria living in our intestines. This discovery could be used in the future to treat patients with a simple regulated diet or by taking tryptophan as a food supplement.  And there is hardly any risk of side effects from artificially increasing an amino acid found in the normal diet.”

Josef Penninger, the lead author, says “I have studied ACE2 for more than 10 years and was completely stunned by this novel link between ACE2 and amino acid balance in the gut. Biology continues to surprise me. Up to a billion people in the world are malnourished, especially the poor and disadvantaged. In Austria alone, around 80,000 people suffer from a chronic inflammatory bowel disease like ulcerative colitis or Crohn’s disease. I hope that our findings have opened a door to a better molecular understanding how malnutrition affects human health. Whether simple tryptophan diets can indeed cure the effects of malnutrition in humans now needs to be carefully tested in clinical trials.”

Candida Linked To Arthritis, Multiple Sclerosis, Psoriasis, and Other Autoimmune Conditions

In this recent study, Candida albicans was shown to cause inflammatory and autoimmune reactions that lead to arthritis, psoriasis and other skin rashes, multiple sclerosis, and many other conditions and diseases – http://candidaplan.com/blog/620/candida-linked-to-arthritis-multiple-sclerosis-psoriasis-and-other-autoimmune-conditions/

Can You Eat Too Many Healthy Fruits and Veggies?

Is it possible to overeat healthy foods? I guess that would depend on the context. The point of the article below is that it is possible to consume too many calories and gain weight, regardless of whether the food is healthy or not. Contrary to this type of logic however, when doing Dr. McCombs Candida Plan – http://candidaplan.com/, we find that eating plenty actually helps to increase weight loss. This is due to the fact that detoxifying the body takes lots of energy and you need to fuel this process. Many people comment that they “haven’t eaten this much in years and they’re still losing weight,” which brings us back to context. Here’s the short article anyway – http://www.sciencedaily.com/releases/2012/07/120724144423.htm

It may make you scratch your head, but in fact it is possible to overeat healthy foods, according to Loyola University Health System registered dietitian Brooke Schantz.

“While fruits are nutritious, too much of even a healthy food can lead to weight gain,” Schantz said. “The key is to remember to control the portion sizes of the foods you consume.”

Schantz reported that overeating healthy foods is easy to do, but the same rules apply to healthy food as junk food. Weight fluctuates based on a basic concept — energy in versus energy out. If your total caloric intake is higher than the energy you burn off in a day, you will gain weight. If it is lower, you will lose weight.

“I have had many patients tell me that they don’t know why they are not losing weight,” Schantz said. “Then they report that they eat fruit all day long. They are almost always shocked when I advise them to watch the quantity of food they eat even if it is healthy.”

Schantz said that one exception applies. Nonstarchy vegetables are difficult to overeat unless they are accompanied by unnecessary calories from sauces, cheeses and butter. This is due to the high water and fiber content of these vegetables coupled with the stretching capacity of the stomach. The vegetables she suggested limiting are those that are high in starch, such as peas, corn and potatoes. Foods that are labeled as fat-free or low-fat are another area of concern.

“People tend to give themselves the freedom to overeat ‘healthy’ foods,” Schantz said. “While the label might say that a food or beverage is low-fat or fat-free, watch the quantity you consume and refrain from eating an excessive amount. Foods that carry these health claims may be high in sugar and calories.”

Context, context, context!

Does Candida Know When To Attack

There is always a wealth of information coming forth that helps to provide greater clarity on how candida becomes problematic in the body. This recent study, as reported in Science Daily, provides some good information and some confusing information. I’ll add some editorial throughout the article – http://www.sciencedaily.com/releases/2012/07/120724153651.htm

The opportunistic fungal pathogen Candida albicans inconspicuously lives in our bodies until it senses that we are weak when it quickly adapts to go on the offensive. The fungus, known for causing yeast and other minor infections, also causes a sometimes-fatal infection known as candidemia in immunocompromised patients An in vivo study, published in mBio, demonstrates how C. albicanscan distinguish between a healthy and an unhealthy host and alter its physiology to attack. [There are several factors that cause the conversion of the normal yeast form of candida to its pathogenic, problematic fungal form – pH, temperature, antibiotics, bacterial cell wall components, etc., The phrase, “senses we are weak” isn’t something that I have ever seen in scientific studies, but it may be another way to state immunsuppression. Even so, I have yet to see that listed as a trigger for yeast-to-fungal conversion. Immunosuppression can play a role in the spread of candida, but some studies indicate that it isn’t a pre-requisite for this to happen. Candidemia is another term for fungal sepsis, or blood-borne fungal infection. Sepsis is one of the top 10 or 11 leading causes of death in the United States, depending on year of reference, and fungal candida causes over 50% of that].

“The ability of the fungus to sense the immune status of its host may be key to its ability to colonize harmlessly in some people but become a deadly pathogen in others,” said Jessica V. Pierce, BA, PhD student in the molecular microbiology program at the Sackler School of Graduate Biomedical Sciences at Tufts. [This is an interesting quote from an author in the study. It can be taken a couple of different ways. It might be interpreted that she is stating that it spreads throughout the body in its fungal form in the presence of an intact immune system, but doesn’t create any imbalances. That would be ignoring a lot of other research that demonstrates how the fungal form of candida creates many imbalances within the body. It has been shown to spread through the body without the immune system being compromised. A second interpretation and the one that I believe she is stating is that as a fungus, it colonizes the digestive tract harmlessly or pathogenically depending on the host immune status. That would ignore the fact that candida colonizes the intestinal tract in its yeast form. It may not be much of a differentiation, but it can be misleading as the fungal form is problematic and the yeast form isn’t.]

“Effective detection and treatment of disease in immunocompromised patients could potentially work by targeting the levels of a protein, Efg1p, that we found influenced the growth of Candida albicans inside the host,” she continued. [As stated before, there are several factors that cause the conversion of yeast-to-fungus. Efg1 has been identified previously as part of the internal mechanism that regulates the yeast-to-hyphal conversion and back again. It’s not the only part and its presence may not be a good indicator of fungal infections, as it can exist in the yeast form also.]

The researchers knew from previous research that Efg1p influences the expression of genes that regulate how harmful a fungal cell can become. Surprisingly, the investigators found that lower Efg1p levels allow the fungal cells to grow to high levels inside a host. Higher levels of the protein result in less growth. [Would the high levels be associated with it’s yeast form and the low levels with its fungal form. That can be a good reason for differentiating between yeast and fungus and not referring to both forms as though they were fungal.]

To examine how the immune status could affect the growth of C. albicans within a host, the researchers fed both healthy and immunocompromised mice equal amounts of two fungal strains containing two different levels of the Efg1p protein.

Fecal pellets from the mice were tested to determine which strain of fungi thrived. In a healthy host, the fungal cells with higher levels of the protein predominated.

In immunocompromised mice, the fungal cells with lower levels of the protein flourished. The researchers noted that lack of interactions with immune cells in the intestinal tract most likely caused the necessary environmental conditions favoring fungal cells that express lower levels of the protein, resulting in fungal overgrowth and setting the stage for systemic infection.

“By having a mixed population with some high Efg1p cells and some low Efg1p cells, the fungus can adjust its physiology to remain benign or become harmful when it colonizes hosts with varying immune statuses. These findings are important because they provide the first steps toward developing more effective methods for detecting and treating serious and stubborn infections caused by Candida albicans, such as candidemia,” said Carol A. Kumamoto, PhD, professor of molecular biology and microbiology at Tufts University School of Medicine and member of the molecular microbiology and genetics program faculties at the Sackler School of Graduate Biomedical Sciences.

The immune system and “good bacteria” within the body act to regulate the size of C. albicans fungal populations in healthy individuals. When the immune system is compromised, the fungus can spread throughout the body. Candidemia, i.e. blood-borne Candida, is the fourth most common blood infection among hospitalized patients in the United States and is found in immunocompromised patients such as babies, those with catheters, and the critically ill. [Here we see the authors state that it is the immune system and the “good bacteria” that help to regulate the candida populations. This would be a very strong statement against the use of antibiotics, as antibiotics destroy the “good bacteria” and suppress the immune system. With Sepsis being one of the top causes of death in the United States and over 50% of that being due to fungal candida, much of that can be prevented by not using antibiotics. That would eliminate sepsis as a leading cause of death and fungal candida as the 4th leading cause of hospital infections. Throughout this article I didn’t see any differentiation between the yeast and fungal forms of candida and I didn’t find it mentioned in the original abstract either. Many studies seem to be limited in the breadth of understanding of candida and the vast amount of past research. Through other studies, it has already been established that immunosuppression is not necessary for the spread of candida. For more research on this, view the Candida Facts Sheet article.  Tests can only serve as indicators, not absolute measures of function in the body. Targeting something like Efg1 doesn’t seem to be a promising advancement in the understanding or treatment of candida. If the purpose is to create another target for antifungal medications, it must be remembered that all medications contain far more harmful effects than beneficial effects. One common effect of antifungal medications  is immunosuppression.

More on Bacillus subtilis

Here’s a list of antibiotics that Bacillus subtilis is used with. It’s effects are against aerobic and non-aerobic bacteria. There is no differentiating between good and bad bacteria, as some people are lead to believe. That differentiation is something put out by the pharmaceuitical companies and MDs. The warrior model of destroying this and that as used in medicine, is antiquated and has been so many decades. The “holistic” approach used by many people is just a variation on the medical warriot model, whereby medications are substituted with something else to bring about destruction. The approach to destroying anything in the body, fails to consider that in doing so, we are destroying ourselves in the process. It’s okay if you want to support those groups, it’s just that the information is misleading.

All bacteria in a balanced system benefit the system. Create the balance and you also create the safeguards against anything that shouldn’t be there. Destroy that balance and you’ll see health start to slip away as the ecosystem starts to collapse into chaos.

As you’ll see below, Bacillus subtilis has been associated with food poisoning, disease conditions, and has been tested for biological applications as a biolgical agent.

Bacillus subtilis is the basis for many antibiotics due to its strong antibacterial function. This antibacterial function will create imbalance within the body by destroying bacteria. It also has a strong antifungal effect and is the basis for antifungal medications, but these, as we know, create other imbalances.

You’ll see below this list of B. subtilis-based antibiotics some more information on B. subtilis. It’s not a risk-free choice. Whatever your decision, make it an informed choice.


B. subtilis
does produce an extracellular toxin known as subtilisin. Although subtilisin has very low toxigenic properties (Gill, 1982), this proteinaceous compound is capable of causing allergic reactions in individuals who are repeatedly exposed to it (Edberg, 1991). Sensitization of workers to subtilisin may be a problem in fermentation facilities where exposure to high concentration of this compound may occur. Exposure limits to subtilisin are regulated by Occupational Safety and Health Administration (OSHA) (29 CFR 1900, et seq.)Biotechnology Program Under Toxic Substances Control Act (TSCA)

Bacillus subtilis Final Risk Assessment

III. HAZARD ASSESSMENT

A. Human Health Hazards

1. Colonization

B. subtilis is widely distributed throughout the environment, particularly in soil, air, and decomposing plant residue. It has shown a capacity to grow over a wide range of temperatures including that of the human body (Claus and Berkeley, 1986). However, B. subtilis does not appear to have any specialized attachment mechanisms typically found in organisms capable of colonizing humans (Edberg, 1991). Given its ubiquity in nature and the environmental conditions under which it is capable of surviving, B. subtilis could be expected to temporarily inhabit the skin and gastrointestinal tract of humans, but it is doubtful that this organism would colonize other sites in the human body (Edberg, 1991).

2. Gene Transfer

The transfer of gene sequences between strains of B. subtilis has been demonstrated when the strains were grown together in soil (Graham and Istock, 1979). In addition, Klier et al. (1983) demonstrated the ability of B. subtilis and B. thuringiensis to exchange high frequency transfer plasmids. Other studies have shown that B. subtilis has the ability to express and secrete toxins or components of the toxins that were acquired from other microorganisms through such transfers of genetic material. B. subtilis expressed subunits of toxins from Bordatella pertussis (Saris et al., 1990a, 1990b), as well as subunits of diphtheria toxin (Hemila et al., 1989) and pneumolysin A pneumococcal toxin (Taira et al., 1989). Although B. subtilis does not appear to possess indigenous virulence factor genes, it is theoretically possible that it may acquire such genes from other bacteria, particularly from closely related bacteria within the genus.

3. Toxin Production

A review of the literature by Edberg (1991) failed to reveal the production of toxins by B. subtilis. Although it has been associated with outbreaks of food poisoning (Gilbert et al., 1981 and Kramer et al., 1982 as cited by Logan, 1988), the exact nature of its involvement has not been established. B. subtilis, like other closely related species in the genus, B. licheniformis, B. pumulis, and B. megaterium, have been shown to be capable of producing lecithinase, an enzyme which disrupts membranes of mammalian cells. However, there has not been any correlation between lecithinase production and human disease in B. subtilis.

4. Measure of the Degree of Virulence

B. subtilis appears to have a low degree of virulence to humans. It does not produce significant quantities of extracellular enzymes or possess other virulence factors that would predispose it to cause infection (Edberg, 1991). There are a number of reports where B. subtilis has been isolated from human infections. Earlier literature contains references to infections caused by B. subtilis. However, as previously stated,the term B. subtilis was synonymous for any aerobic sporeforming bacilli, and quite possibly, many of these infections were associated with B. cereus. In a recent British review article, Logan (1988) cites more recent cases of B. subtilis infections in which identification of the bacterium appeared reliable. Infections include a case of endocarditis in a drug abuse patient; fatal pneumonia and bacteremia in three leukemic patients; septicemia in a patient with breast cancer; and infection of a necrotic axillary tumor in another breast cancer patient. Isolation of B. subtilis was also made from surgical wound-drainage sites, from a subphrenic abscess from a breast prosthesis, and from two ventriculo-atrial shunt infections (as cited by Logan, 1988).

Reviews of Bacillus infections from several major hospitals suggest that B. subtilis is an organism with low virulence. Idhe and Armstrong (1973) reported that Bacillus infections were encountered only twelve times over a 6-1/2 year period. Species identification of these Bacillus infections was not made. In another hospital study over a 6-yr. period, only two of the 24 cases of bacteremia caused by Bacillus (of a total of 1,038 cases) were due to B. subtilis (as cited by Edberg, 1991). Many of these patients were immunocompromised or had long term indwelling foreign bodies such as a Hickman catheter.

B. subtilis has also been implicated in several cases of food poisoning (Gilbert et al., 1981 and Kramer et al., 1982 as cited by Logan, 1988).

As previously mentioned, B. subtilis produces a number of enzymes, including subtilisin, for use in laundry detergent products. There have been a number of cases of allergic or hypersensitivity reactions, including dermatitis and respiratory distress after the use of these laundry products (Norris et al., 1981).

5. Conclusions

B. subtilis is not a human pathogen, nor is it toxigenic like some other members of the genus. The virulence characteristics of the microorganism are low. According to Edberg (1991) either the number of microorganisms challenging the individual must be very high or the immune status of the individual very low in order for infection with B. subtilis to occur.

B. Environmental Hazards

3. Hazards to Other Microorganisms

B. subtilis has been shown to produce a wide variety of antibacterial and antifungal compounds (Katz and Demain, 1977; Korzybski et al., 1978). It produces novel antibiotics such as difficidin and oxydifficidin that have activity against a wide spectrum of aerobic and anaerobic bacteria (Zimmerman et al., 1987) as well as more common antibiotics such as bacitracin, bacillin, and bacillomycin B (Parry et al., 1983). The use of B. subtilis as a biocontrol agent of fungal plant pathogens is being investigated because of the effects of antifungal compounds on Monilinia fructicola (McKeen et al., 1986), Aspergillus flavus and A. parasiticus (Kimura and Hirano, 1988), and Rhizoctonia (Loeffler et al., 1986).

Although B. subtilis produces a variety of antibiotic compounds in culture media, the importance of antibiotic production in the environment is unknown (Alexander, 1977).

B. subtilisis not a frank human pathogen, but has on several occasions been isolated from human infections. Infections attributed to B. subtilis include bacteremia, endocarditis, pneumonia, and septicemia. However, these infections were found in patients in compromised immune states. There must be immunosuppression of the host followed by inoculation in high numbers before infection with B. subtilis canoccur. There also have been several reported cases of food poisoning attributed to large numbers of B. subtilis contaminated food. B. subtilis does not produce significant quantities of extracellular enzymes or other factors that would predispose it to cause infection. Unlike several other species in the genus, B. subtilis is not consider toxigenic. B. subtilis does produce the extracellular enzyme subtilisin that has been reported to cause allergic or hypersensitivity reactions in individuals repeatedly exposed to it.

In conclusion, the use of B. subtilis in fermentation facilities for the production of enzymes or specialty chemicals has low risk. Although not completely innocuous, the industrial use of B. subtilis presents low risk of adverse effects to human health or the environment.
