Bacillus Subtilis: How to Select the Best Probiotic for Dog's Microbiome

Introduction

Probiotics play a vital role in your dog's health. First, it maintains the balance of the intestinal microbial community. Dogs have a large number of microorganisms in their intestines, which interact with each other and work together to maintain the normal function of the intestines. When the intestinal microbial community is out of balance, it may lead to various health problems, such as diarrhea, constipation, indigestion and so on. Probiotics can restore the balance of the intestinal microbial community by increasing the number of beneficial bacteria and inhibiting the growth of harmful bacteria.

Secondly, probiotics can enhance your dog's immunity. The immune system of dogs is closely related to the intestines, and the beneficial bacteria in the intestines can stimulate the development and function of the immune system. Probiotics can promote the production of immune cells, enhance the activity of immune cells, and improve the dog's resistance to disease. For example, some studies have shown that probiotics can increase the level of immunoglobulins in dogs, thus enhancing their immunity.

In addition, probiotics promote nutrient absorption. A dog's intestinal tract is the main place where nutrients are absorbed, and probiotics can help break down the nutrients in food so that they can be more easily absorbed and utilized by the dog. For example, probiotics can produce a variety of digestive enzymes that help dogs digest nutrients such as proteins, fats and carbohydrates. At the same time, probiotics can promote the absorption of vitamins and minerals in the intestines and improve the utilization of nutrients.

In short, probiotics play a key role in the health of dogs, which can maintain the balance of intestinal microbial communities, enhance immunity, promote nutrient absorption and so on. Therefore, it is very necessary to supplement probiotics for dogs.

 

What is Bacillus Subtilis?

1.Classification and Name Origin

Bacillus subtilis holds a significant position within the realm of bacteria. It is a Gram-positive aerobic bacterium belonging to the genus Bacillus. This genus is highly diverse, currently comprising over 300 species. The Bacillus subtilis group, which is one of the crucial taxa within the genus, has undergone an evolution in its composition. Initially, it consisted of Bacillus subtilis, Bacillus licheniformis, and Bacillus sphaericus. However, as of 2019, it has expanded to include 22 validly described species and 3 subspecies.

The name Bacillus subtilis is derived from its propensity to colonize in the juice of a chytrid leachate. This bacterium exhibits a wide distribution pattern, being commonly found in soil and decaying organic matter. Its individual cells possess dimensions of (0.7 - 0.8) μm × (2 - 3) μm and display a uniform coloration. Notably, it lacks a pod membrane and flagellum, yet it is capable of movement. The Gram staining test reveals a positive result. The spores of Bacillus subtilis measure (0.6 - 0.9)μm × (1.0 - 1.5)μm and are located either in the center of the cell body or slightly off-center. Interestingly, the cell body does not expand after spore formation.

When it comes to colony characteristics, the surface of Bacillus subtilis colonies is rough and opaque, appearing dirty white or slightly yellow. In liquid media, it usually forms wrinkled walls. As an aerobic bacterium, it can utilize proteins and various sugars. It also breaks down tryptophan, which is an important aspect of its metabolic activity.

Bacillus subtilis has garnered significant attention due to its various beneficial properties. It is often used in the field of biotechnology and probiotics. In biotechnology, it can produce a range of valuable enzymes and metabolites. For example, it is a source of amylases, proteases, and lipases, which have applications in industries such as food processing, detergent manufacturing, and textile production. In the context of probiotics, Bacillus subtilis can help maintain the balance of the gut microbiota in animals and humans. It achieves this by competing with harmful bacteria for resources and space in the intestine, as well as by producing antimicrobial substances that inhibit the growth of pathogens.

Moreover, its spore-forming ability gives it an added advantage. The spores are highly resistant to harsh environmental conditions such as heat, desiccation, and radiation. This allows Bacillus subtilis to survive in unfavorable environments and remain viable until more suitable conditions are encountered. When the spores reach a favorable environment, they can germinate and resume their normal bacterial activities.

In conclusion, Bacillus subtilis is a remarkable bacterium with a wide range of characteristics and applications. Its prevalence in nature, unique morphological and physiological features, and beneficial properties make it a subject of extensive research and utilization in multiple fields. Whether it is in enhancing industrial processes or promoting health, Bacillus subtilis continues to play an important role and holds great potential for further exploration and development.

2.Magic Spores

Bacillus subtilis in the growth of poor environmental conditions, lack of nutrients and other unsuitable environments will enter the spore dormancy, and the formation of spores with a strong anticorrosive effect. The spores are able to survive in extreme environments such as high temperature, drought, acid and alkali.

During the formation of spores, the bacterial cell first undergoes a series of morphological and physiological changes. The cell wall thickens, forming the budding wall, while the cytoplasm is concentrated and the chromosomes are condensed. Subsequently, the bacterial cell gradually shrinks to about 1/10 of its original size, forming an oval or cylindrical spore.

The spore wall is mainly composed of peptidoglycan, protein and lipid, which gradually accumulate during the formation of spores, forming a solid barrier to protect the spores from the external environment.

With characteristics such as resistance to high temperature and drought, the bacillus has a great advantage in animal nutrition. For example, Bacillus subtilis is added to animal feed in the form of spores, which are living cells in a dormant state, able to withstand the adverse environment during feed processing, and stable and easy to store after preparation into bacteriophage. After entering the animal intestinal tract, the bacterial spores can be rapidly revived and reproduced, and play its beneficial properties, including improving the intestinal flora of the animal, enhancing the immunity of the body, and providing a variety of enzymes required by the animal, which can make up for the lack of enzymes in the body of the animal, and promote the growth and development of the animal.

In addition, after Bacillus subtilis has been treated with germination and microcapsule encapsulation, it has good stability in the state of germination, and is resistant to oxidation, extrusion, and high temperature, and can withstand high temperature for a long period of time up to 60°C, and can survive for 20 minutes at a temperature of 120°C; it is resistant to acid and alkali, and can maintain its activity in an acidic gastric environment, and can withstand the attack of saliva and bile, and it is the live bacterium among the microorganisms that can be directed to the large and small intestine for 100% of the time.

How Does Bacillus Subtilis Probiotic?

1. Create An Environment for Other Probiotics

Bacillus subtilis, being an aerobic bacterium, assumes a highly significant role within a dog's intestinal tract. It actively participates in shaping the gut environment to foster the growth and activity of other beneficial probiotics.

One of the primary mechanisms through which Bacillus subtilis exerts its influence is by absorbing oxygen. In the dog's intestine, the presence of oxygen can limit the colonization and functionality of certain probiotics. Lactobacillus, a bacterium that is partially anaerobic, benefits greatly from the oxygen reduction. In an anaerobic environment, Lactobacillus is able to produce lactic acid. This lactic acid serves as a natural inhibitor, impeding the growth and proliferation of harmful bacteria such as Escherichia coli and Salmonella. These pathogenic bacteria can cause a host of intestinal issues, including diarrhea, vomiting, and infections. By creating an environment conducive to Lactobacillus growth, Bacillus subtilis indirectly helps in controlling the population of harmful microbes.

Bifidobacteria, which are strictly anaerobic, also rely on the oxygen-depleted environment created by Bacillus subtilis. In the low-oxygen conditions, Bifidobacteria can thrive and multiply. The presence of a healthy population of Bifidobacteria is associated with numerous benefits for the host dog. They contribute to improved digestion and nutrient absorption, enhance the immune system, and help maintain the integrity of the intestinal lining.

Beyond oxygen consumption, Bacillus subtilis further modifies the intestinal environment in ways that are favorable to other probiotics. It actively lowers the intestinal pH through the secretion of various substances during its growth. Organic acids are among the metabolites released by Bacillus subtilis. These acids not only contribute to the reduction in pH but also have antimicrobial properties, directly targeting harmful bacteria. A lower pH environment is more suitable for the survival and growth of many probiotics. It inhibits the growth of acid-sensitive pathogens while providing an ideal setting for beneficial bacteria to establish and expand their populations.

Moreover, the metabolites of Bacillus subtilis serve as a source of nutrition for other probiotics. They supply essential compounds that are required for the growth and reproduction of Lactobacillus, Bifidobacteria, and other beneficial microbes. This mutualistic relationship among the different probiotics helps in creating a stable and healthy intestinal microecosystem.

In summary, Bacillus subtilis acts as a key regulator of the intestinal microenvironment in dogs. Through its oxygen-absorbing capabilities and the production of beneficial metabolites, it paves the way for the success of other probiotics like lactobacilli and bifidobacteria. This, in turn, leads to a more balanced gut microbiota, where the number of pathogenic bacteria is kept in check. The reduction in pathogenic bacteria translates into a decreased risk of intestinal diseases, ensuring the overall well-being and health of the dog. By understanding and appreciating the role of Bacillus subtilis, pet owners and veterinarians can make more informed decisions regarding the use of probiotics to maintain and enhance the health of a dog's intestinal tract.

2.Competitive Exclusion of Pathogenic Bacteria

Bacillus subtilis, as a beneficial bacterium, plays a crucial role in maintaining the health of an animal's intestine by effectively reducing the colonization of pathogenic bacteria. When Bacillus subtilis and other good bacteria establish themselves as the dominant intestinal flora, they employ a remarkable mechanism known as competitive exclusion.

Take the example of poultry farming. In the context of antimicrobial-free farming, necrotizing enterocolitis poses a significant threat. The main culprit behind this disease is Clostridium perfringens. Research has demonstrated that Bacillus subtilis has the capacity to counteract Clostridium perfringens. By colonizing the intestine and becoming the dominant microbiota, Bacillus subtilis outcompetes Clostridium perfringens for resources and attachment sites. This "first come, first served" principle is fundamental. Once Bacillus subtilis has firmly established its presence in the gut, it creates an environment that is inhospitable for pathogenic bacteria. It monopolizes the available niches and nutrients, leaving little opportunity for Clostridium perfringens to gain a foothold.

Moreover, Bacillus subtilis not only occupies space but also actively safeguards the integrity of the intestinal barrier. The intestinal barrier is the first line of defense against pathogenic invaders. When Bacillus subtilis dominates, it helps maintain the structural and functional integrity of this barrier, preventing pathogenic bacteria from breaching and causing damage. This protection is essential as a compromised intestinal barrier can lead to a cascade of health issues, including increased susceptibility to infections and inflammation.

In addition to competitive exclusion, Bacillus subtilis has another weapon in its arsenal - the secretion of antimicrobial substances. These substances are produced as part of its metabolic activities. For instance, its metabolites include surface-active elements. These elements have a direct and potent effect on pathogenic bacteria. They target the cell membrane of pathogenic bacteria, disrupting its structure and function. By damaging the cell membrane, the pathogenic bacteria lose their ability to maintain homeostasis and carry out essential cellular processes. This ultimately leads to their death, thereby achieving a sterilization effect.

The ability of Bacillus subtilis to secrete antimicrobial substances further reinforces its role as a guardian of the intestinal ecosystem. It provides an additional layer of defense against pathogenic bacteria, ensuring that the balance of the gut microbiota is maintained. This dual mechanism of competitive exclusion and antimicrobial secretion makes Bacillus subtilis a valuable asset in promoting animal health, especially in the context of preventing diseases caused by pathogenic bacteria.

In conclusion, Bacillus subtilis is a powerful ally in the fight against pathogenic bacteria in the animal intestine. Its ability to reduce the colonization of pathogens through competitive exclusion and direct inhibition via antimicrobial substances is of great significance. Understanding and harnessing these mechanisms can have far-reaching implications for improving animal health and welfare, whether in poultry farming or other livestock industries.

Selection Criteria for Dog Probiotics

1. Activity and Viability of the Strain

Choosing a probiotic strain with high activity and good viability is essential for your dog's health. As we have learned from many sources, probiotics play an important role in the intestinal tract of dogs, and their activity and viability directly affect their effectiveness.

First of all, stomach acid tolerance is one of the most important measures of probiotic activity. The pH value of gastric acid in dogs is much lower than that of humans, and it is difficult for common probiotics to survive in such a highly acidic environment. Only probiotics that are resistant to stomach acidity can remain active when passing through the dog's stomach and reach the intestines smoothly.

Secondly, high temperature resistance is also key. Probiotics are generally suitable for survival in a low temperature environment, and the storage temperature should not exceed 36℃. However, during the processing, transportation and storage of probiotic products, they often experience higher temperatures, especially in summer, when the temperature can even reach 60℃. This requires probiotics to be temperature resistant to ensure that they remain active in all environments.

It is also important that the probiotic is antibiotic resistant. Dogs are often given antibiotics during illness, and probiotics and antibiotics should not normally be used at the same time as their effects will cancel each other out. Choosing antibiotic-resistant probiotics can regulate the intestinal environment without delaying the treatment of your dog's disease.

2.Tolerance to the Internal Environment

The environment in the dog's body is a severe test for probiotics, especially the acidic environment in the stomach. Only those probiotics that can tolerate the dog's internal environment can work in the dog's intestinal tract.

As mentioned earlier, probiotics with stomach acid tolerant properties will be able to survive the acidic environment of your dog's stomach. In addition, probiotics need to be able to tolerate other internal environmental factors such as bile. Probiotics for dogs and cats have to pass through the mouth, esophagus, stomach to reach the intestines, and a good probiotic for dogs and cats must be able to withstand the acidity and bile salts of the gastric fluid of dogs and cats ph1.5 - 2.

3. Adhesion and Colonization Ability

Probiotic strains possessing excellent adherence and colonization abilities are of utmost importance in optimizing the health of a dog's intestinal tract. These abilities enable the probiotics to establish a stable and long-term presence, thereby conferring a multitude of benefits.

Take the case of Small Pet Gastrointestinal Probiotics. The unique formulation of this product, consisting entirely of fermented probiotics, sets it apart. Notably, it refrains from incorporating additional taste masking agents or other auxiliary substances. One characteristic that indicates the presence of live bacteria is its incomplete solubility in water. This property is significant as it implies that the probiotics are in a viable state. Live bacteria have a greater propensity to adhere to the inner lining of the dog's intestine. Once attached, they can commence the process of colonization. Through colonization, they create a favorable microenvironment that promotes the growth of other beneficial bacteria and suppresses the growth of harmful pathogens. This, in turn, helps to maintain a balanced and healthy intestinal microbiota, which is essential for proper digestion, nutrient absorption, and overall gut health.

Another exemplary product is the Pampered Puppy Intestinal Lobo Dog Probiotic. This probiotic contains an intestinal mucosal care agent as a key component, along with highly efficient probiotics. The intestinal mucosal care agent plays a crucial role in repairing and promoting the regeneration of the intestinal mucosa. A healthy intestinal mucosa is vital as it serves as a physical barrier against harmful substances and pathogens. By enhancing the integrity of the mucosa, the probiotic not only protects the intestine but also improves the rate of probiotic immobilization. When probiotics are better able to adhere and colonize, they can more effectively carry out their functions. They can rapidly adjust the intestinal and gastrointestinal functions, ensuring that the digestive process runs smoothly. This leads to enhanced nutrient absorption, which is crucial for the dog's growth, development, and overall well-being.

The enhanced adherence and colonization abilities of these probiotics also have implications for the dog's immune system. A healthy gut microbiota, supported by well-adhered and colonized probiotics, can interact with the immune cells in the intestine. This interaction helps to train and regulate the immune system, making it more responsive to threats while also preventing overactive immune responses that could lead to inflammation or allergies.

In conclusion, probiotics with good adherence and colonization capabilities are essential for a dog's intestinal health. Products like Small Pet Gastrointestinal Probiotics and Pampered Puppy Intestinal Lobo Dog Probiotic exemplify how these properties can be harnessed to provide comprehensive care for a dog's gut. By maintaining a healthy intestinal microbiota, repairing the intestinal mucosa, and promoting nutrient absorption, these probiotics contribute to the overall health and vitality of our canine companions. Pet owners and veterinarians should be aware of the significance of these factors when selecting probiotics to ensure the best possible care for their dogs.

4.Anti-microbial Ability

When it comes to safeguarding the intestinal health of our canine companions, probiotics that possess the ability to fend off harmful microorganisms are a top priority in our selection process.

Bacillus subtilis is a prime example of such a beneficial probiotic. It has a remarkable mechanism for combating pathogenic bacteria. Through the secretion of specific antibacterial substances, it actively targets and curbs the growth of harmful microbes. The metabolites of Bacillus subtilis include surface active agents, which are potent weapons in its antibacterial arsenal. These substances can directly interact with the cell membranes of pathogenic bacteria, causing structural damage and ultimately leading to the death of the pathogens. This sterilization effect is crucial in maintaining a healthy balance within the dog's intestine. By reducing the population of harmful bacteria, Bacillus subtilis creates an environment that is more conducive to the growth and activity of beneficial microbiota, thereby promoting proper digestion and nutrient absorption.

Another noteworthy product is the Bilbao Bilbao Bilbao Shake & Shake Probiotic Dog Food. This dog food is fortified with Lactobacillus acidophilus and Bifidobacterium animalis, which together contain a staggering 100 billion active probiotics. These probiotics work in harmony to protect the dog's intestine. They have a multi-faceted approach to inhibiting harmful bacteria. Firstly, they can effectively seize the oxygen that is essential for the survival of harmful bacteria. In an anaerobic environment, many harmful bacteria struggle to thrive, and this gives the beneficial probiotics an upper hand. Secondly, they generate lactic acid as a byproduct of their metabolism. Lactic acid is known to have inhibitory properties against a wide range of harmful bacteria. It can lower the pH of the intestinal environment, making it less hospitable for pathogens. Lastly, these probiotics are adept at occupying the adhesive positions in the intestinal tract that harmful bacteria would otherwise use to colonize. By doing so, they prevent the attachment and proliferation of harmful microbes, effectively restoring the healthy intestinal micro-ecological environment of the dog.

A healthy intestinal micro-ecosystem is not only vital for digestion but also has far-reaching implications for the dog's overall health. The intestine is a major site of immune activity, and a balanced microbiota helps to train and regulate the immune system. When harmful bacteria are kept in check by effective probiotics, the risk of various diseases is significantly reduced. These diseases can range from simple digestive disorders such as diarrhea and vomiting to more serious conditions that may affect other organs due to the translocation of harmful bacteria from the intestine.

In conclusion, choosing probiotics that can actively resist harmful microorganisms is a crucial step in ensuring the well-being of our dogs. Pet owners and veterinarians alike should be vigilant in selecting the most suitable probiotics to promote the long-term health and vitality of our beloved canine friends.

Moreover, probiotics enhance the dog's immune system. They stimulate the production of antibodies and immune cells, enabling the dog to better defend against pathogens such as viruses, bacteria, and parasites. This strengthened immune response can reduce the frequency and severity of infections and diseases. Additionally, a balanced gut microbiota has been associated with improved overall well-being, including better skin and coat condition, as well as enhanced behavior and cognitive function.

Bacillus subtilis belongs to the phylum Firmicutes in the bacterial kingdom. It is named "subtilis" because it is commonly found and thrives in grassy environments. This bacterium has a unique life cycle and characteristics that make it a valuable probiotic option for dogs.

Bacillus subtilis has the remarkable ability to form spores. The spore formation process is a survival mechanism that allows the bacterium to withstand harsh conditions. When environmental conditions become unfavorable, such as during periods of nutrient depletion or extreme temperatures, the bacterium transforms into a spore. The spore is highly resistant to heat, drought, and other stressors. It can survive in a dormant state for extended periods until it encounters more favorable conditions, at which point it can germinate and resume its normal bacterial activity. This spore-forming ability gives Bacillus subtilis an advantage in animal nutrition applications. It can survive the manufacturing processes of probiotic products, as well as the acidic environment of the dog's stomach, and reach the intestines intact, where it can then exert its beneficial effects.

As an aerobic bacterium, Bacillus subtilis consumes oxygen in the dog's intestine. This reduction in oxygen levels creates a more favorable anaerobic environment for other beneficial bacteria such as lactobacilli and bifidobacteria. These anaerobic probiotics are essential for maintaining a healthy gut microbiota. By promoting the growth and activity of these beneficial bacteria, Bacillus subtilis helps to crowd out harmful pathogens and reduce the risk of intestinal diseases.

When Bacillus subtilis and other beneficial bacteria establish themselves as the dominant microbiota in the dog's intestine, they can competitively exclude pathogenic bacteria. They do this by occupying the available attachment sites on the intestinal lining and competing for nutrients. This makes it more difficult for pathogenic bacteria to colonize and cause infections, thereby protecting the dog's intestinal health.

The viability and survival ability of the probiotic strain are of utmost importance. A high-quality probiotic product should contain live and active Bacillus subtilis strains. The strains should be able to survive the manufacturing process, storage, and transit through the dog's digestive system. This ensures that a sufficient number of viable bacteria reach the intestines to exert their beneficial effects.

Probiotics must be able to tolerate the harsh internal environment of the dog's body. The stomach, in particular, has a highly acidic pH that can kill many bacteria. A good probiotic strain should have mechanisms to resist the acidic environment and survive until they reach the intestines. Additionally, they should be able to adapt to the different conditions in the intestine, such as changes in pH, bile salts, and the presence of other digestive enzymes.

The ability of the probiotic strain to adhere to the intestinal lining and colonize is crucial. Only when the bacteria can attach to the intestinal wall can they establish a long-term presence and interact with the host's immune system and gut microbiota. Strains with strong adhesion and colonization abilities are more likely to provide lasting benefits to the dog's intestinal health.

A good probiotic should possess antimicrobial capacity to combat harmful microorganisms. Bacillus subtilis can produce antimicrobial substances such as antibiotics and bacteriocins that can inhibit the growth of pathogenic bacteria. This helps to maintain a healthy balance in the gut microbiota and protect the dog from infections.

There are several types of Bacillus subtilis probiotic products available for dogs. One common form is capsules. Capsules are designed to protect the probiotic bacteria from the acidic environment of the stomach and release them in the intestine. They are convenient for dosing and can ensure the delivery of a precise amount of probiotics. Another type is tablets. Tablets are more stable and easier to store than some other forms. However, they may require a more elaborate manufacturing process to ensure the viability of the bacteria. Additionally, there are powdered probiotics that can be mixed with the dog's food. This form is often more palatable for dogs and allows for easy incorporation into their diet.

Bacillus subtilis is generally considered safe and does not cause infections under normal circumstances. However, in dogs with compromised immune systems, such as those with underlying diseases or undergoing immunosuppressive treatments, there is a slightly increased risk of infection. It is important to note that if the probiotic product is of poor quality or used incorrectly, it may also introduce unwanted bacteria or contaminants that could lead to infections.

Although Bacillus subtilis itself may not be inherently drug-resistant, there is a concern that it could carry and transfer resistance genes to other bacteria. This could potentially contribute to the development of antibiotic-resistant bacteria, which would make treating infections more challenging. To minimize this risk, it is crucial to select high-quality probiotic products from reputable manufacturers and use them according to the recommended guidelines.

Under normal conditions, the metabolites produced by Bacillus subtilis are usually harmless. However, if a probiotic product is contaminated or stored improperly, it could produce harmful metabolites. For example, if the product is exposed to high temperatures or moisture, it may lead to the growth of unwanted microorganisms or the production of toxic substances. Therefore, proper storage and handling of probiotic products are essential to ensure the safety of the dog.

In conclusion, Bacillus subtilis can be a valuable probiotic for maintaining the health of a dog's microbiome. However, when selecting a probiotic product, it is important to consider various factors such as the strain's viability, tolerance to the internal environment, adhesion and colonization ability, and antimicrobial capacity.
