A species of anaerobic bacteria, in the family Lachnospiraceae, found in RUMINANTS. It is considered both gram-positive and gram-negative.
A large group of anaerobic bacteria which show up as pink (negative) when treated by the Gram-staining method.
A family of gram-negative bacteria found primarily in the intestinal tracts and mucous membranes of warm-blooded animals. Its organisms are sometimes pathogenic.
The first stomach of ruminants. It lies on the left side of the body, occupying the whole of the left side of the abdomen and even stretching across the median plane of the body to the right side. It is capacious, divided into an upper and a lower sac, each of which has a blind sac at its posterior extremity. The rumen is lined by mucous membrane containing no digestive glands, but mucus-secreting glands are present in large numbers. Coarse, partially chewed food is stored and churned in the rumen until the animal finds circumstances convenient for rumination. When this occurs, little balls of food are regurgitated through the esophagus into the mouth, and are subjected to a second more thorough mastication, swallowed, and passed on into other parts of the compound stomach. (From Black's Veterinary Dictionary, 17th ed)
A genus of gram-positive, rod-shaped bacteria found in cavities of man and animals, animal and plant products, infections of soft tissue, and soil. Some species may be pathogenic.

One of the three domains of life (the others being Eukarya and ARCHAEA), also called Eubacteria. They are unicellular prokaryotic microorganisms which generally possess rigid cell walls, multiply by cell division, and exhibit three principal forms: round or coccal, rodlike or bacillary, and spiral or spirochetal. Bacteria can be classified by their response to OXYGEN: aerobic, anaerobic, or facultatively anaerobic; by the mode by which they obtain their energy: chemotrophy (via chemical reaction) or PHOTOTROPHY (via light reaction); for chemotrophs by their source of chemical energy: CHEMOLITHOTROPHY (from inorganic compounds) or chemoorganotrophy (from organic compounds); and by their source for CARBON; NITROGEN; etc.; HETEROTROPHY (from organic sources) or AUTOTROPHY (from CARBON DIOXIDE). They can also be classified by whether or not they stain (based on the structure of their CELL WALLS) with CRYSTAL VIOLET dye: gram-negative or gram-positive.
High molecular weight polysaccharides present in the cell walls of all plants. Pectins cement cell walls together. They are used as emulsifiers and stabilizers in the food industry. They have been tried for a variety of therapeutic uses including as antidiarrheals, where they are now generally considered ineffective, and in the treatment of hypercholesterolemia.
'Anaerobic Bacteria' are types of bacteria that do not require oxygen for growth and can often cause diseases in humans, including dental caries, gas gangrene, and tetanus, among others.

The Butyrivibrio fibrisolvens tet(W) gene is carried on the novel conjugative transposon TnB1230, which contains duplicated nitroreductase coding sequences. (1/20)

The Butyrivibrio fibrisolvens tet(W) gene is located on the conjugative transposon TnB1230. TnB1230 encodes transfer proteins with 48 to 67% identity to some of those encoded by Tn1549. tet(W) is flanked by directly repeated sequences with significant homology to oxygen-insensitive nitroreductases. The 340 nucleotides upstream of tet(W) are strongly conserved and are required for tetracycline resistance.  (+info)

Use of community genome arrays (CGAs) to assess the effects of Acacia angustissima on rumen ecology. (2/20)

This research developed a community genome array (CGA) to assess the effects of Acacia angustissima on rumen microbiology. A. angustissima produces non-protein amino acids as well as tannins, which may be toxic to animals, and CGA was used to assess the effects of this plant on the ecology of the rumen. CGAs were developed using a 7.5 cmx2.5 cm nylon membrane format that included up to 96 bacterial genomes. It was possible to separately hybridize large numbers of membranes at once using this mini-membrane format. Pair-wise cross-hybridization experiments were conducted to determine the degree of cross-hybridization between strains; cross-hybridization occurred between strains of the same species, but little cross-reactivity was observed among different species. CGAs were successfully used to survey the microbial communities of animals consuming an A. angustissima containing diet but quantification was not precise. To properly quantify and validate the CGA, Fibrobacter and Ruminococcus populations were independently assessed using 16S rDNA probes to extracted rRNA. The CGA detected an increase in these populations as acacia increased in the diet, which was confirmed by rRNA analysis. There was a great deal of variation among strains of the same species in how they responded to A. angustissima. However, in general Selenomonas strains tended to be resistant to the tannins in the acacia while Butyrivibrio fibrisolvens was sensitive. On the other hand some species, like streptococci, varied. Streptococcus bovis-like strains were sensitive to an increase in acacia in the diet while Streptococcus gallolyticus-like strains were resistant. Strep. gallolyticus has independently been shown to be resistant to tannins. It is concluded that there is significant variation in tannin resistance between strains of the same species. This implies that there are specific molecular mechanisms at play that are independent of the phylogenetic position of the organism.  (+info)

A new strain of Butyrivibrio fibrisolvens that has high ability to isomerize linoleic acid to conjugated linoleic acid. (3/20)

A new strain of Butyrivibrio fibrisolvens (TH1) that has high potential to produce conjugated linoleic acid (CLA) was isolated. Strain TH1 had higher LA isomerase (LA-I) activity, and was much more tolerant to linoleic acid (LA) than other strains examined. However, high CLA reductase (CLA-R) activity resulted in the temporary accumulation of CLA and subsequent conversion to trans-vaccenic acid (t-VA). When LA was added to growing TH1 cultures in a solution with dimethylsulfoxide (LA/DMSO), CLA produced was greater than when LA was added in a mixture with bovine serum albumin (BSA). The number of viable cells decreased upon addition of LA/DMSO, but then increased as the CLA decreased upon its conversion to t-VA. This result suggests that B. fibrisolvens can resume growing by the removal of CLA from the cells. Most CLA was released from B. fibrisolvens cells by gentle washing with BSA, suggesting that CLA bound to the cells might be removed in the rumen and large intestine. Thus, CLA production by B. fibrisolvens in the digestive tract could be increased by a reduction in CLA-R activity without accompanying an overall decrease in the cell number of B. fibrisolvens. Fatty acids (FAs) with 18 carbon backbone inducted LA-I activity, whereas unsaturated FAs induced CLA-R activity, suggesting that FAs stimulate the synthesis of LA-I and CLA-R. Providing a diet with a low ratio of unsaturated to saturated FAs may favor CLA production.  (+info)

Horizontal transfer of erythromycin resistance from Clostridium difficile to Butyrivibrio fibrisolvens. (4/20)

This study demonstrates for the first time the in vitro transfer of the erythromycin resistance gene erm(B) between two obligate anaerobes, the human spore-forming pathogen Clostridium difficile and the rumen commensal Butyrivibrio fibrisolvens, suggesting that this event might occur also in the natural environment.  (+info)

Oral administration of butyrivibrio fibrisolvens, a butyrate-producing bacterium, decreases the formation of aberrant crypt foci in the colon and rectum of mice. (5/20)

Butyrivibrio fibrisolvens, a butyrate-producing ruminal bacterium, was evaluated for use as a probiotic to prevent colorectal cancer. Oral administration to Jcl:ICR mice of a new strain of B. fibrisolvens (MDT-1) that produces butyrate at a high rate (10(9) cfu/dose) increased the rate of butyrate production by fecal microbes, suggesting that MDT-1 can grow in the gut. The number of colorectal aberrant crypt foci (ACF), putative preneoplastic lesions induced by 1,2-dimethylhydrazine, was reduced after MDT-1 administration (10(9) cfu/dose, 3 times/wk for 4 wk). The number of aberrant crypts (ACs), number of foci having 3 or 4 ACs per focus, and the percentage of mice having 3 or 4 ACs per focus were also reduced, suggesting that the progress of lesions was suppressed by MDT-1. Interestingly, the MDT-1 cell homogenate did not have a similar beneficial effect. MDT-1 had low beta-glucuronidase activity, and administration of MDT-1 reduced the beta-glucuronidase activity in the colorectal contents. The numbers of natural killer (NK) and NKT cells in the spleen were markedly enhanced in response to MDT-1. Decreased beta-glucuronidase activity and increased numbers of NK and NKT cells and butyrate production may explain in part why MDT-1 administration suppressed ACF formation. These results suggest that colorectal cancer may be prevented or suppressed by the utilization of MDT-1 as a probiotic. Administration of MDT-1 had no harmful effect on the health of mice at least for 3 mo.  (+info)

Molecular analysis of tet(W) gene-mediated tetracycline resistance in dominant intestinal Bifidobacterium species from healthy humans. (6/20)

tet(W) was found responsible for tetracycline resistance (MICs, 4 to > or =32 microg ml(-1)) in dominant bifidobacterial species from the gastrointestinal tracts of healthy humans. The gene from Bifidobacterium longum H66 proved to be identical over a 2.6-kbp region to the recently described tet(W) determinant of Butyrivibrio fibrisolvens.  (+info)

Effect of oral administration of Butyrivibrio fibrisolvens MDT-1 on experimental enterocolitis in mice. (7/20)

Butyrivibrio fibrisolvens MDT-1, a butyrate-producing strain, was evaluated for use as a probiotic to prevent enterocolitis. Oral administration of the MDT-1 strain (10(9) CFU/dose) alleviated the symptoms of colitis (including body weight loss, diarrhea, bloody stool, organic disorder, and mucosal damage) that are induced in mice drinking water that contains 3.0% dextran sulfate sodium. In addition, myeloperoxidase (MPO) activity levels in colonic tissue were reduced, suggesting that MDT-1 mitigates bowel inflammation. The addition of MDT-1 culture supernatant inhibited the growth of nine clinical isolates of Campylobacter jejuni and Campylobacter coli that could potentially cause enterocolitis. Infection of mice with C. coli 11580-3, one of the isolates inhibited by MDT-1 in vitro, resulted in diarrhea, mucosal damage, increased MPO activity levels in colonic tissue, increased numbers of C. coli in the cecum, and decreased body weight gain. However, administration of MDT-1 to mice, prior to and during C. coli infection, reduced these effects. These results suggest that Campylobacter-induced enterocolitis can be alleviated by using B. fibrisolvens as a probiotic.  (+info)

Isolation and characterization of putative Pseudobutyrivibrio ruminis promoters. (8/20)

Novel plasmids were constructed for the analysis of DNA fragments from the rumen bacterium Pseudobutyrivibrio ruminis. Five previously unidentified promoters were characterized using a novel primer extension method to identify transcription start sites. The genes downstream of these promoters were not identified, and their activity in expression of genomic traits in wild-type P. ruminis remains putative. Comparison with promoters from this and closely related species revealed a consensus sequence resembling the binding motif for the RNA polymerase sigma(70)-like factor complex. Consensus -35 and -10 sequences within these elements were TTGACA and ATAATATA respectively, interspaced by 15-16 bp. The consensus for the -10 element was extended by one nucleotide upstream and downstream of the standard hexamer (indicated in bold). Promoter strengths were measured by reverse transcription quantitative PCR and beta-glucuronidase assays. No correlation was found between the composition and context of elements within P. ruminis promoters, and promoter strength. However, a mutation within the -35 element of one promoter revealed that transcriptional strength and choice of transcription start site were sensitive to this single nucleotide change.  (+info)

Butyrivibrio is a genus of gram-positive, anaerobic bacteria that are commonly found in the gastrointestinal tracts of animals, including ruminants and humans. These bacteria play an important role in the digestion of plant material by producing enzymes that break down complex carbohydrates into simpler sugars, which can then be fermented to produce butyrate, a short-chain fatty acid that serves as an energy source for the host animal.

The name Butyrivibrio is derived from the Latin word "butyrum," meaning butter, and the Greek word "vibrios," meaning rod-shaped. This reflects the fact that these bacteria are known to produce butyrate, which is a fatty acid that is commonly found in butter and other dairy products.

Butyrivibrio species are generally considered to be beneficial members of the gut microbiota, as they help to maintain a healthy balance of microorganisms in the digestive tract and contribute to the breakdown and absorption of nutrients from food. However, like all bacteria, they can potentially cause disease if they enter other parts of the body or if they overgrow and disrupt the normal balance of the gut microbiota.

Gram-negative anaerobic bacteria are a type of bacteria that do not require oxygen to grow and are characterized by their cell wall structure, which does not retain crystal violet dye in the Gram staining procedure. This is because they lack a thick peptidoglycan layer in their cell walls, which is typically stained dark purple in Gram-positive bacteria. Instead, gram-negative bacteria have an outer membrane that contains lipopolysaccharides (LPS), which can be toxic to human cells and contribute to the pathogenicity of these organisms.

Examples of gram-negative anaerobic bacteria include Bacteroides fragilis, Prevotella species, and Porphyromonas species. These bacteria are commonly found in the human mouth, gastrointestinal tract, and genitourinary tract, and can cause a variety of infections, including abscesses, wound infections, and bacteremia.

It's important to note that while gram-negative anaerobic bacteria do not require oxygen to grow, some may still tolerate or even prefer oxygen-rich environments. Therefore, the term "anaerobe" can be somewhat misleading when used to describe these organisms.

Bacteroidaceae is a family of gram-negative, anaerobic or facultatively anaerobic, non-spore forming bacteria that are commonly found in the human gastrointestinal tract. They are rod-shaped and can vary in size and shape. Bacteroidaceae are important breakdowners of complex carbohydrates and proteins in the gut, and play a significant role in maintaining the health and homeostasis of the intestinal microbiota. Some members of this family can also be opportunistic pathogens and have been associated with various infections and diseases, such as abscesses, bacteremia, and periodontal disease.

The rumen is the largest compartment of the stomach in ruminant animals, such as cows, goats, and sheep. It is a specialized fermentation chamber where microbes break down tough plant material into nutrients that the animal can absorb and use for energy and growth. The rumen contains billions of microorganisms, including bacteria, protozoa, and fungi, which help to break down cellulose and other complex carbohydrates in the plant material through fermentation.

The rumen is characterized by its large size, muscular walls, and the presence of a thick mat of partially digested food and microbes called the rumen mat or cud. The animal regurgitates the rumen contents periodically to chew it again, which helps to break down the plant material further and mix it with saliva, creating a more favorable environment for fermentation.

The rumen plays an essential role in the digestion and nutrition of ruminant animals, allowing them to thrive on a diet of low-quality plant material that would be difficult for other animals to digest.

"Eubacterium" is a genus of Gram-positive, obligately anaerobic, non-sporeforming bacteria that are commonly found in the human gastrointestinal tract. These bacteria are typically rod-shaped and can be either straight or curved. They play an important role in the breakdown of complex carbohydrates and the production of short-chain fatty acids in the gut, which are beneficial for host health. Some species of Eubacterium have also been shown to have probiotic properties and may provide health benefits when consumed in appropriate quantities. However, other species can be opportunistic pathogens and cause infections under certain circumstances.

"Gram-positive asporegenous rods" is a term used to describe a specific shape and staining characteristic of certain types of bacteria. Here's the medical definition:

Gram-positive: These are bacteria that appear purple or violet when subjected to a Gram stain, a laboratory technique used to classify bacteria based on their cell wall structure. In this method, a primary stain (crystal violet) is applied, followed by a mordant (a substance that helps the dye bind to the bacterial cell). Then, a decolorizer (alcohol or acetone) is used to wash away the primary stain from the Gram-negative bacteria, leaving them unstained. A counterstain (safranin or fuchsin) is then applied, which stains the decolorized Gram-negative bacteria pink or red. However, Gram-positive bacteria retain the primary stain and appear purple or violet.

Asporegenous: These are bacteria that do not form spores under any conditions. Spores are a dormant, tough, and highly resistant form of bacterial cells that can survive extreme environmental conditions. Asporegenous bacteria lack this ability to form spores.

Rods: This term refers to the shape of the bacteria. Rod-shaped bacteria are also known as bacilli. They are longer than they are wide, and their size may vary from 0.5 to several micrometers in length and about 0.2 to 1.0 micrometer in width.

Examples of Gram-positive asporegenous rods include species from the genera Listeria, Corynebacterium, and Bacillus (some strains). These bacteria can cause various diseases, ranging from foodborne illnesses to severe skin and respiratory infections.

Xylosidases are a group of enzymes that catalyze the hydrolysis of xylosides, which are glycosides with a xylose sugar. Specifically, they cleave the terminal β-1,4-linked D-xylopyranoside residues from various substrates such as xylooligosaccharides and xylan. These enzymes play an important role in the breakdown and metabolism of plant-derived polysaccharides, particularly hemicelluloses, which are a major component of plant biomass. Xylosidases have potential applications in various industrial processes, including biofuel production and animal feed manufacturing.

Hydrogenation, in the context of food science and biochemistry, refers to the process of adding hydrogen atoms to certain unsaturated fats or oils, converting them into saturated fats. This is typically done through a chemical reaction using hydrogen gas in the presence of a catalyst, often a metal such as nickel or palladium.

The process of hydrogenation increases the stability and shelf life of fats and oils, but it can also lead to the formation of trans fats, which have been linked to various health issues, including heart disease. Therefore, the use of partially hydrogenated oils has been largely phased out in many countries.

Xylans are a type of complex carbohydrate, specifically a hemicellulose, that are found in the cell walls of many plants. They are made up of a backbone of beta-1,4-linked xylose sugar molecules and can be substituted with various side groups such as arabinose, glucuronic acid, and acetyl groups. Xylans are indigestible by humans, but they can be broken down by certain microorganisms in the gut through a process called fermentation, which can produce short-chain fatty acids that have beneficial effects on health.

Bacteroides are a genus of gram-negative, anaerobic, rod-shaped bacteria that are normally present in the human gastrointestinal tract. They are part of the normal gut microbiota and play an important role in breaking down complex carbohydrates and other substances in the gut. However, some species of Bacteroides can cause opportunistic infections, particularly in individuals with weakened immune systems or when they spread to other parts of the body. They are resistant to many commonly used antibiotics, making infections caused by these bacteria difficult to treat.

Butyrates are a type of fatty acid, specifically called short-chain fatty acids (SCFAs), that are produced in the gut through the fermentation of dietary fiber by gut bacteria. The name "butyrate" comes from the Latin word for butter, "butyrum," as butyrate was first isolated from butter.

Butyrates have several important functions in the body. They serve as a primary energy source for colonic cells and play a role in maintaining the health and integrity of the intestinal lining. Additionally, butyrates have been shown to have anti-inflammatory effects, regulate gene expression, and may even help prevent certain types of cancer.

In medical contexts, butyrate supplements are sometimes used to treat conditions such as ulcerative colitis, a type of inflammatory bowel disease (IBD), due to their anti-inflammatory properties and ability to promote gut health. However, more research is needed to fully understand the potential therapeutic uses of butyrates and their long-term effects on human health.

Xylan Endo-1,3-beta-Xylosidase is an enzyme that breaks down xylan, which is a major component of hemicellulose in plant cell walls. This enzyme specifically catalyzes the hydrolysis of 1,3-beta-D-xylosidic linkages in xylans, resulting in the release of xylose units from the xylan backbone. It is involved in the process of breaking down plant material for various industrial applications and in the natural decomposition of plants by microorganisms.

'Clostridium' is a genus of gram-positive, rod-shaped bacteria that are widely distributed in nature, including in soil, water, and the gastrointestinal tracts of animals and humans. Many species of Clostridium are anaerobic, meaning they can grow and reproduce in environments with little or no oxygen. Some species of Clostridium are capable of producing toxins that can cause serious and sometimes life-threatening illnesses in humans and animals.

Some notable species of Clostridium include:

* Clostridium tetani, which causes tetanus (also known as lockjaw)
* Clostridium botulinum, which produces botulinum toxin, the most potent neurotoxin known and the cause of botulism
* Clostridium difficile, which can cause severe diarrhea and colitis, particularly in people who have recently taken antibiotics
* Clostridium perfringens, which can cause food poisoning and gas gangrene.

It is important to note that not all species of Clostridium are harmful, and some are even beneficial, such as those used in the production of certain fermented foods like sauerkraut and natto. However, due to their ability to produce toxins and cause illness, it is important to handle and dispose of materials contaminated with Clostridium species carefully, especially in healthcare settings.

Linoleic acid is an essential polyunsaturated fatty acid, specifically an omega-6 fatty acid. It is called "essential" because our bodies cannot produce it; therefore, it must be obtained through our diet. Linoleic acid is a crucial component of cell membranes and is involved in the production of prostaglandins, which are hormone-like substances that regulate various bodily functions such as inflammation, blood pressure, and muscle contraction.

Foods rich in linoleic acid include vegetable oils (such as soybean, corn, and sunflower oil), nuts, seeds, and some fruits and vegetables. It is important to maintain a balance between omega-6 and omega-3 fatty acids in the diet, as excessive consumption of omega-6 fatty acids can contribute to inflammation and other health issues.

Bacteria are single-celled microorganisms that are among the earliest known life forms on Earth. They are typically characterized as having a cell wall and no membrane-bound organelles. The majority of bacteria have a prokaryotic organization, meaning they lack a nucleus and other membrane-bound organelles.

Bacteria exist in diverse environments and can be found in every habitat on Earth, including soil, water, and the bodies of plants and animals. Some bacteria are beneficial to their hosts, while others can cause disease. Beneficial bacteria play important roles in processes such as digestion, nitrogen fixation, and biogeochemical cycling.

Bacteria reproduce asexually through binary fission or budding, and some species can also exchange genetic material through conjugation. They have a wide range of metabolic capabilities, with many using organic compounds as their source of energy, while others are capable of photosynthesis or chemosynthesis.

Bacteria are highly adaptable and can evolve rapidly in response to environmental changes. This has led to the development of antibiotic resistance in some species, which poses a significant public health challenge. Understanding the biology and behavior of bacteria is essential for developing strategies to prevent and treat bacterial infections and diseases.

Pectins are complex polysaccharides that are commonly found in the cell walls of plants. In the context of food and nutrition, pectins are often referred to as dietary fiber. They have a variety of important functions within the body, including promoting digestive health by adding bulk to stools and helping to regulate bowel movements.

Pectins are also used in the medical field as a demulcent, which is a substance that forms a soothing film over mucous membranes. This can be helpful in treating conditions such as gastroesophageal reflux disease (GERD) and inflammatory bowel disease (IBD).

In addition to their use in medicine, pectins are widely used in the food industry as a gelling agent, thickener, and stabilizer. They are commonly found in jams, jellies, and other preserved fruits, as well as in baked goods and confectionery products.

Anaerobic bacteria are a type of bacteria that do not require oxygen to grow and survive. Instead, they can grow in environments that have little or no oxygen. Some anaerobic bacteria can even be harmed or killed by exposure to oxygen. These bacteria play important roles in many natural processes, such as decomposition and the breakdown of organic matter in the digestive system. However, some anaerobic bacteria can also cause disease in humans and animals, particularly when they infect areas of the body that are normally oxygen-rich. Examples of anaerobic bacterial infections include tetanus, gas gangrene, and dental abscesses.

Bacillaceae is a family of Gram-positive bacteria that are typically rod-shaped (bacilli) and can form endospores under adverse conditions. These bacteria are widely distributed in nature, including in soil, water, and the gastrointestinal tracts of animals. Some members of this family are capable of causing disease in humans, such as Bacillus anthracis, which causes anthrax, and Bacillus cereus, which can cause foodborne illness. Other genera in this family include Lysinibacillus, Paenibacillus, and Jeotgalibacillus.

Stearic acid is not typically considered a medical term, but rather a chemical compound. It is a saturated fatty acid with the chemical formula C18H36O2. Stearic acid is commonly found in various foods such as animal fats and vegetable oils, including cocoa butter and palm oil.

In a medical context, stearic acid might be mentioned in relation to nutrition or cosmetics. For example, it may be listed as an ingredient in some skincare products or medications where it is used as an emollient or thickening agent. It's also worth noting that while stearic acid is a saturated fat, some studies suggest that it may have a more neutral effect on blood cholesterol levels compared to other saturated fats. However, this is still a topic of ongoing research and debate in the medical community.

Fermentation is a metabolic process in which an organism converts carbohydrates into alcohol or organic acids using enzymes. In the absence of oxygen, certain bacteria, yeasts, and fungi convert sugars into carbon dioxide, hydrogen, and various end products, such as alcohol, lactic acid, or acetic acid. This process is commonly used in food production, such as in making bread, wine, and beer, as well as in industrial applications for the production of biofuels and chemicals.

Tetracycline resistance is a type of antibiotic resistance where bacteria have developed the ability to survive and grow in the presence of tetracyclines, a class of antibiotics used to treat a wide range of bacterial infections. This resistance can be mediated through various mechanisms such as:

1. Efflux pumps: These are proteins that actively pump tetracyclines out of the bacterial cell, reducing the intracellular concentration of the antibiotic and preventing it from reaching its target site.
2. Ribosomal protection proteins (RPPs): These proteins bind to the ribosomes (the sites of protein synthesis) and prevent tetracyclines from binding, thus allowing protein synthesis to continue in the presence of the antibiotic.
3. Enzymatic modification: Some bacteria produce enzymes that modify tetracyclines, rendering them ineffective or less effective against bacterial growth.
4. Mutations in target sites: Bacteria can also acquire mutations in their genome that alter the structure of the target site (ribosomes), preventing tetracyclines from binding and inhibiting protein synthesis.

Tetracycline resistance has become a significant public health concern, as it limits the therapeutic options for treating bacterial infections and contributes to the emergence and spread of multidrug-resistant bacteria. The primary causes of tetracycline resistance include the misuse and overuse of antibiotics in both human medicine and agriculture.

Volatile fatty acids (VFA) are a type of fatty acid that have a low molecular weight and are known for their ability to evaporate at room temperature. They are produced in the body during the breakdown of carbohydrates and proteins in the absence of oxygen, such as in the digestive tract by certain bacteria.

The most common volatile fatty acids include acetic acid, propionic acid, and butyric acid. These compounds have various roles in the body, including providing energy to cells in the intestines, modulating immune function, and regulating the growth of certain bacteria. They are also used as precursors for the synthesis of other molecules, such as cholesterol and bile acids.

In addition to their role in the body, volatile fatty acids are also important in the food industry, where they are used as flavorings and preservatives. They are produced naturally during fermentation and aging processes, and are responsible for the distinctive flavors of foods such as yogurt, cheese, and wine.

Bacterial DNA refers to the genetic material found in bacteria. It is composed of a double-stranded helix containing four nucleotide bases - adenine (A), thymine (T), guanine (G), and cytosine (C) - that are linked together by phosphodiester bonds. The sequence of these bases in the DNA molecule carries the genetic information necessary for the growth, development, and reproduction of bacteria.

Bacterial DNA is circular in most bacterial species, although some have linear chromosomes. In addition to the main chromosome, many bacteria also contain small circular pieces of DNA called plasmids that can carry additional genes and provide resistance to antibiotics or other environmental stressors.

Unlike eukaryotic cells, which have their DNA enclosed within a nucleus, bacterial DNA is present in the cytoplasm of the cell, where it is in direct contact with the cell's metabolic machinery. This allows for rapid gene expression and regulation in response to changing environmental conditions.

Glycoside hydrolases are a class of enzymes that catalyze the hydrolysis of glycosidic bonds found in various substrates such as polysaccharides, oligosaccharides, and glycoproteins. These enzymes break down complex carbohydrates into simpler sugars by cleaving the glycosidic linkages that connect monosaccharide units.

Glycoside hydrolases are classified based on their mechanism of action and the type of glycosidic bond they hydrolyze. The classification system is maintained by the International Union of Biochemistry and Molecular Biology (IUBMB). Each enzyme in this class is assigned a unique Enzyme Commission (EC) number, which reflects its specificity towards the substrate and the type of reaction it catalyzes.

These enzymes have various applications in different industries, including food processing, biofuel production, pulp and paper manufacturing, and biomedical research. In medicine, glycoside hydrolases are used to diagnose and monitor certain medical conditions, such as carbohydrate-deficient glycoprotein syndrome, a rare inherited disorder affecting the structure of glycoproteins.

Ribosomal RNA (rRNA) is a type of RNA that combines with proteins to form ribosomes, which are complex structures inside cells where protein synthesis occurs. The "16S" refers to the sedimentation coefficient of the rRNA molecule, which is a measure of its size and shape. In particular, 16S rRNA is a component of the smaller subunit of the prokaryotic ribosome (found in bacteria and archaea), and is often used as a molecular marker for identifying and classifying these organisms due to its relative stability and conservation among species. The sequence of 16S rRNA can be compared across different species to determine their evolutionary relationships and taxonomic positions.

Eukaryota is a domain that consists of organisms whose cells have a true nucleus and complex organelles. This domain includes animals, plants, fungi, and protists. The term "eukaryote" comes from the Greek words "eu," meaning true or good, and "karyon," meaning nut or kernel. In eukaryotic cells, the genetic material is housed within a membrane-bound nucleus, and the DNA is organized into chromosomes. This is in contrast to prokaryotic cells, which do not have a true nucleus and have their genetic material dispersed throughout the cytoplasm.

Eukaryotic cells are generally larger and more complex than prokaryotic cells. They have many different organelles, including mitochondria, chloroplasts, endoplasmic reticulum, and Golgi apparatus, that perform specific functions to support the cell's metabolism and survival. Eukaryotic cells also have a cytoskeleton made up of microtubules, actin filaments, and intermediate filaments, which provide structure and shape to the cell and allow for movement of organelles and other cellular components.

Eukaryotes are diverse and can be found in many different environments, ranging from single-celled organisms that live in water or soil to multicellular organisms that live on land or in aquatic habitats. Some eukaryotes are unicellular, meaning they consist of a single cell, while others are multicellular, meaning they consist of many cells that work together to form tissues and organs.

In summary, Eukaryota is a domain of organisms whose cells have a true nucleus and complex organelles. This domain includes animals, plants, fungi, and protists, and the eukaryotic cells are generally larger and more complex than prokaryotic cells.

"Cattle" is a term used in the agricultural and veterinary fields to refer to domesticated animals of the genus *Bos*, primarily *Bos taurus* (European cattle) and *Bos indicus* (Zebu). These animals are often raised for meat, milk, leather, and labor. They are also known as bovines or cows (for females), bulls (intact males), and steers/bullocks (castrated males). However, in a strict medical definition, "cattle" does not apply to humans or other animals.

Molecular sequence data refers to the specific arrangement of molecules, most commonly nucleotides in DNA or RNA, or amino acids in proteins, that make up a biological macromolecule. This data is generated through laboratory techniques such as sequencing, and provides information about the exact order of the constituent molecules. This data is crucial in various fields of biology, including genetics, evolution, and molecular biology, allowing for comparisons between different organisms, identification of genetic variations, and studies of gene function and regulation.

rRNA (ribosomal RNA) is not a type of gene itself, but rather a crucial component that is transcribed from genes known as ribosomal DNA (rDNA). In cells, rRNA plays an essential role in protein synthesis by assembling with ribosomal proteins to form ribosomes. Ribosomes are complex structures where the translation of mRNA into proteins occurs. There are multiple types of rRNA molecules, including 5S, 5.8S, 18S, and 28S rRNAs in eukaryotic cells, each with specific functions during protein synthesis.

In summary, 'Genes, rRNA' would refer to the genetic regions (genes) that code for ribosomal RNA molecules, which are vital components of the protein synthesis machinery within cells.

Bacterial RNA refers to the genetic material present in bacteria that is composed of ribonucleic acid (RNA). Unlike higher organisms, bacteria contain a single circular chromosome made up of DNA, along with smaller circular pieces of DNA called plasmids. These bacterial genetic materials contain the information necessary for the growth and reproduction of the organism.

Bacterial RNA can be divided into three main categories: messenger RNA (mRNA), ribosomal RNA (rRNA), and transfer RNA (tRNA). mRNA carries genetic information copied from DNA, which is then translated into proteins by the rRNA and tRNA molecules. rRNA is a structural component of the ribosome, where protein synthesis occurs, while tRNA acts as an adapter that brings amino acids to the ribosome during protein synthesis.

Bacterial RNA plays a crucial role in various cellular processes, including gene expression, protein synthesis, and regulation of metabolic pathways. Understanding the structure and function of bacterial RNA is essential for developing new antibiotics and other therapeutic strategies to combat bacterial infections.

Here the one notable outlier is Catenibacterium. Intriguingly, the other people Ive seen with such high levels are all unhealthy. One of them, like Paul, is undergoing chemotherapy. Is this a microbe that associates somehow with disease? And if so, is there anything he can (or should) do about it?. Ken Lassessen at https://cfsremission.com has compiled an extensive list of actions that can increase or reduce common microbes and he finds evidence that flaxseed oil is associated with reduced Catenibacterium. Is it worth trying? Ask your doctor.. Peer reviewed studies of colorectal cancer and the microbiome have singled out Fusobacterium. In fact, that microbe is so clearly associated that destroying it with the antibiotic metronidazole slows tumors in mice. There is none in Pauls sample, either because his current cancer treatments have eliminated it, or because it just wasnt detected in this sample..
