The influence of a diet rich in wheat fibre on the human faecal flora. (1/1602)The effect on the faecal flora of adding wheat fibre to a controlled diet in four healthy volunteers for a 3-week period has been observed. No change in the concentration of the bacteria in the bacterial groups counted was found, although there was a slight increase in total output associated with increased faecal weight. The predominant organisms in all subjects were non-sporing anaerobes, but the dominant species in each subject was different and was unaffected by changing the diet. Similarly, the concentration of faecal beta-glucuronidase detected in two subjects was unaltered and the concentration of clostridia able to dehydrogenate the steroid nucleus found in one subject was unaltered. It is suggested that the faecal microflora is not primarily controlled by the presence of undigested food residues in the large bowel. (+info)
Simultaneous detection of Bacteroides forsythus and Prevotella intermedia by 16S rRNA gene-directed multiplex PCR. (2/1602)In a 16S rRNA gene-directed multiplex PCR, Prevotella intermedia- and Bacteroides forsythus-specific reverse primers were combined with a single conserved forward primer. A 660-bp fragment and an 840-bp fragment that were specific for both species could be amplified simultaneously. A total of 152 clinical samples, subgingival plaque and swabs of three different oral mucosae, from 38 periodontitis patients were used for the evaluation. (+info)
Characterization of bacteroides melaninogenicus. (3/1602)Fifty-eight human isolates of Bacteroides melaninogenicus, 42 from a variety of clinical infections and the rest from normal flora, were studied for pigment production and ultraviolet light fluorescence and by forty biochemical and other tests, including end-product analysis by gas-liquid chromatography. In a number of instances, tests were repeated several times and the results were reproducible. Agar plate dilution susceptibility tests were also performed to 12 antimicrobial agents. These 58 strains could be reliably placed into three groups, corresponding to the three subspecies described, based on seven characteristics. These included acid production in peptone-yeast-glucose medium, production of n-butyric acid from peptone-yeast-glucose medium, esculin hydrolysis, starch hydrolysis, indole production, effect on milk, and lipase production. Production of hydrogen gas in peptone-yeast-fructose medium may be another distinguishing characteristic. In general there was not much difference in the susceptibility of the three groups to the various antimicrobial agents tested. Two strains had a minimal inhibitory concentration of penicillin G of 16 and 32 U/ml, respectively. Three strains did not produce a black pigment in spite of prolonged incubation on blood-containing media. (+info)
Phylogenetic position of Chitinophaga pinensis in the Flexibacter-Bacteroides-Cytophaga phylum. (4/1602)Comparison of the 16S rRNA gene sequence determined for Chitinophaga pinensis showed that this species is most closely related to Flexibacter filiformis in the Flexibacter-Bacteroides-Cytophaga phylum. These two chitinolytic bacteria, which are characterized by transformation into spherical bodies on ageing, belong to a strongly supported lineage that also includes Cytophaga arvensicola, Flavobacterium ferrugineum and Flexibacter sancti. The lineage is distinct from the microcyst-forming species Sporocytophaga myxococcoides. (+info)
T cell specificity and cross reactivity towards enterobacteria, bacteroides, bifidobacterium, and antigens from resident intestinal flora in humans. (5/1602)BACKGROUND: T cell responses to normal intestinal bacteria or their products may be important in the immunopathogenesis of chronic enterocolitis. AIMS: To investigate the T cell specificity and cross reactivity towards intestinal bacteria. PATIENTS/METHODS: T cell clones were isolated with phytohaemagglutinin from peripheral blood and biopsy specimens of inflamed and non-inflamed colon from five patients with inflammatory bowel disease (IBD) and two controls. T cell clones were restimulated with anaerobic Bacteroides and Bifidobacteria species, enterobacteria, and direct isolates of aerobic intestinal flora. T cell phenotype was analysed by single-cell immunocyte assay. RESULTS: Analysis of 96 T cell clones isolated from peripheral blood and biopsy specimens from two patients with IBD showed that both Bifidobacterium and Bacteroides species specifically stimulate proliferation of CD4+TCRalphabeta+ T cell clones from both sites and that cross reactivity exists between these anaerobic bacteria and different enterobacteria. Analysis of 210 T cell clones isolated from three patients with IBD and two controls showed that indigenous aerobic flora specifically stimulate T cell clones from peripheral blood and biopsy specimens from a foreign subject. Some of these flora specific T cell clones were cross reactive with defined enterobacteria. In addition, T cell clones stimulated by their own indigenous aerobic flora were identified in patients with IBD. CONCLUSION: Immune responses to antigens from the intestinal microflora involve a complex network of T cell specificities. (+info)
Characterization of Bacteroides forsythus strains from cat and dog bite wounds in humans and comparison with monkey and human oral strains. (6/1602)Bacteroides forsythus strains recovered from cat and dog bite wound infections in humans (n = 3), monkey oral strains (n = 3), and the human oral ATCC 43037 type strain were characterized by using phenotypic characteristics, enzymatic tests, whole cell fatty acid analysis, sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) analysis, PCR fingerprinting, and 16S rDNA (genes coding for rRNA) sequencing. All three bite wound isolates grew on brucella agar supplemented with 5% sheep blood, vitamin K1, and hemin. These strains, unlike the ATCC strain and previously described monkey oral and human clinical strains, did not require N-acetylmuramic acid supplementation for growth as pure cultures. However, their phenotypic characteristics, except for catalase production, were similar to those of previously identified strains. PCR fingerprinting analysis showed differences in band patterns from the ATCC strain. Also, SDS-PAGE and whole cell fatty acid analysis indicated that the dog and cat bite wound strains were similar but not identical to the human B. forsythus ATCC 43037 type strain and the monkey oral strains. The rDNA sequence analysis indicated that the three bite wound isolates had 99.93% homology with each other and 98.9 and 99.22% homology with the human ATCC 43037 and monkey oral strains, respectively. These results suggest that there are host-specific variations within each group. (+info)
Differential induction of colitis and gastritis in HLA-B27 transgenic rats selectively colonized with Bacteroides vulgatus or Escherichia coli. (7/1602)Resident bacteria play an important role in initiating and perpetuating gastrointestinal inflammation. We previously demonstrated that six commensal bacteria including Bacteroides vulgatus caused more aggressive colitis and gastritis in HLA-B27 transgenic rats than did the other five bacteria without B. vulgatus. This study compared the degree of gastrointestinal inflammation in gnotobiotic HLA-B27 transgenic rats monoassociated with either B. vulgatus or Escherichia coli. Gnotobiotic transgenic rats raised in Trexler isolators were selectively colonized with either B. vulgatus or E. coli. Control rats were either germfree or colonized with six common commensal bacteria (Streptococcus faecium, E. coli, Streptococcus avium, Eubacterium contortum, Peptostreptococcus productus, and B. vulgatus [DESEP-B]). After 1 month, all the rats were killed and tissues were prepared for histologic and biochemical evaluation. Colitis induced by B. vulgatus monoassociation was almost equal to that in DESEP-B-colonized rats and was significantly more severe than E. coli-induced colitis, which was absent by histological testing and mild by colonic myeloperoxidase and interleukin-1beta concentration determinations. However, gastritis was detectable only in DESEP-B-associated rats. These studies suggest that not all resident bacteria have equal proinflammatory capabilities, since B. vulgatus alone is more active than E. coli alone in inducing colitis, and that colitis and gastritis result from different luminal bacterial stimuli.

Bacteroides infections are a type of bacterial infection caused by the Bacteroides genus of bacteria. These bacteria are commonly found in the human gut and play an important role in the digestive process, but they can also cause infections in various parts of the body.
Types of Bacteroides Infections:
1. Bacteroides fragilis: This type of infection is caused by the Bacteroides fragilis bacterium and is typically found in the gut, skin, and respiratory tract.
2. Bacteroides vulgatus: This type of infection is caused by the Bacteroides vulgatus bacterium and is commonly found in the gut and respiratory tract.
3. Bacteroides caccae: This type of infection is caused by the Bacteroides caccae bacterium and is typically found in the gut and skin.
4. Bacteroides distasonis: This type of infection is caused by the Bacteroides distasonis bacterium and is commonly found in the gut and respiratory tract.
5. Bacteroides eggerthii: This type of infection is caused by the Bacteroides eggerthii bacterium and is typically found in the gut and skin.
Causes and Risk Factors:
Bacteroides infections can occur due to a variety of factors, including:
1. Weakened immune system: People with weakened immune systems, such as those with cancer, HIV/AIDS, or taking immunosuppressive drugs, are more susceptible to Bacteroides infections.
2. Injury or trauma: Injuries or traumas to the skin or gut can provide an entry point for Bacteroides bacteria to enter the body and cause an infection.
3. Surgery: People who have undergone surgery, particularly gastrointestinal surgery, are at risk of developing Bacteroides infections.
4. Contaminated medical devices: Medical devices such as catheters or implantable devices can become contaminated with Bacteroides bacteria and cause an infection.
5. Poor hygiene: Poor hygiene practices, such as not washing hands regularly or not sterilizing medical equipment, can increase the risk of developing a Bacteroides infection.
6. Smoking: Smoking can weaken the immune system and increase the risk of developing Bacteroides infections.
7. Diabetes: People with diabetes are more susceptible to developing Bacteroides infections, particularly in the skin and soft tissues.
8. Obesity: Obesity can increase the risk of developing Bacteroides infections, particularly in the gut and respiratory tract.
The symptoms of Bacteroides infections vary depending on the location of the infection and the severity of the infection. Some common symptoms of Bacteroides infections include:
1. Skin infections: Redness, swelling, warmth, and pain at the site of the infection. Pus-filled abscesses may also develop.
2. Respiratory infections: Coughing, difficulty breathing, chest pain, and fever.
3. Gastrointestinal infections: Diarrhea, abdominal pain, nausea, and vomiting.
4. Bone and joint infections: Pain, swelling, and limited mobility in the affected limb.
5. Urinary tract infections: Painful urination, frequency of urination, and cloudy or strong-smelling urine.
6. Sepsis: Fever, chills, rapid heart rate, and confusion or disorientation.
Bacteroides infections can be difficult to diagnose because the bacteria can be found on the skin and in the gut of healthy individuals. However, there are several tests that can help healthcare providers diagnose a Bacteroides infection:
1. Blood cultures: Blood cultures can be used to detect the presence of Bacteroides bacteria in the bloodstream.
2. Urine cultures: Urine cultures can be used to detect the presence of Bacteroides bacteria in the urinary tract.
3. Surgical wound cultures: Surgical wound cultures can be used to detect the presence of Bacteroides bacteria in wounds.
4. Imaging studies: Imaging studies such as X-rays, CT scans, and MRI scans can help healthcare providers visualize the location and extent of the infection.
5. PCR (polymerase chain reaction) testing: PCR testing can be used to detect the presence of Bacteroides DNA in a sample of blood or tissue.
The treatment of Bacteroides infections depends on the severity and location of the infection, as well as the individual's overall health. Some common treatments for Bacteroides infections include:
1. Antibiotics: Bacteroides bacteria are typically resistant to antibiotics, but some strains may be susceptible to certain types of antibiotics such as cefoxitin, imipenem-cilastatin, and meropenem.
2. Surgical drainage: If the infection is localized and does not respond to antibiotic therapy, surgical drainage may be necessary to remove the infected tissue or fluid.
3. Supportive care: Patients with severe Bacteroides infections may require hospitalization and supportive care such as intravenous fluids, oxygen therapy, and monitoring of vital signs.
4. Probiotics: Probiotics are beneficial bacteria that can help restore the balance of gut flora and may be used to treat Bacteroides infections.
5. Enzyme-based therapy: Enzyme-based therapy, such as collagenase, can be used to break down the extracellular matrix that surrounds the bacteria and help eliminate them from the body.
Preventing Bacteroides infections is challenging, but there are some measures that can be taken to reduce the risk of infection. These include:
1. Proper wound care: Wounds should be cleaned and covered with sterile dressings to prevent bacterial growth.
2. Good hygiene: Hands should be washed frequently, especially after contact with wounds or contaminated surfaces.
3. Proper sterilization of medical equipment: All medical equipment should be properly sterilized before use to prevent the spread of infection.
4. Vaccination: Vaccines are available for some types of Bacteroides, such as the Bacteroides fragilis vaccine, which can help prevent infections caused by this bacterium.
5. Antibiotic stewardship: Antibiotics should be used judiciously and only when necessary to prevent the development of antibiotic-resistant bacteria.
Overall, Bacteroides infections can be challenging to diagnose and treat, but with appropriate management and prevention strategies, patients can recover fully. It is important to seek medical attention if symptoms persist or worsen over time, as early intervention can improve outcomes.
The symptoms of foot rot can vary depending on the severity of the infection, but may include:
* Redness, swelling, and warmth of the affected area
* Pus-filled blisters or ulcers on the skin
* Foul odor emanating from the infected tissue
* Lameness or reluctance to bear weight on the affected foot
* Increased temperature and loss of appetite in severe cases
If left untreated, foot rot can lead to more serious complications such as cellulitis, abscesses, and laminitis. Treatment typically involves antibiotics, rest, and supportive care to manage pain and inflammation. In severe cases, surgical debridement of infected tissue may be necessary.
Prevention is key in managing foot rot, and this includes keeping the feet and lower legs clean and dry, providing proper ventilation and drainage, and trimming the nails and hooves regularly to prevent overgrowth.
There are several types of abscesses, including:
1. Skin abscesses: These occur when a bacterial infection causes pus to accumulate under the skin. They may appear as red, swollen bumps on the surface of the skin.
2. Internal abscesses: These occur when an infection causes pus to accumulate within an internal organ or tissue. Examples include abscesses that form in the liver, lungs, or brain.
3. Perianal abscesses: These occur when an infection causes pus to accumulate near the anus. They may be caused by a variety of factors, including poor hygiene, anal sex, or underlying conditions such as Crohn's disease.
4. Dental abscesses: These occur when an infection causes pus to accumulate within a tooth or the surrounding tissue. They are often caused by poor oral hygiene or dental trauma.
The symptoms of an abscess can vary depending on its location and severity. Common symptoms include:
* Redness, swelling, and warmth around the affected area
* Pain or discomfort in the affected area
* Fever or chills
* Discharge of pus from the affected area
* Bad breath (if the abscess is located in the mouth)
If an abscess is not treated, it can lead to serious complications, including:
* Further spread of the infection to other parts of the body
* Inflammation of surrounding tissues and organs
* Formation of a pocket of pus that can become infected and lead to further complications
* Sepsis, a life-threatening condition caused by the spread of infection through the bloodstream.
Treatment of an abscess usually involves drainage of the pus and antibiotics to clear the infection. In some cases, surgery may be necessary to remove affected tissue or repair damaged structures.
It's important to seek medical attention if you suspect that you have an abscess, as prompt treatment can help prevent serious complications.
The main causes of periodontitis are poor oral hygiene, smoking, and certain medical conditions such as diabetes and heart disease. The symptoms of periodontitis include:
* Redness and swelling of the gums
* Bad breath
* Bleeding while brushing or flossing
* Pocket formation between the teeth and gums
* Loose teeth or changes in the bite
* Changes in the color or shape of the gums
If left untreated, periodontitis can lead to serious complications such as:
* Tooth loss
* Bone loss around the teeth
* Infection of the dental implant or prosthetic tooth
* Spread of bacteria to other parts of the body, leading to systemic diseases such as heart disease and diabetes.
Periodontitis can be treated by a dentist or periodontist with a combination of non-surgical and surgical procedures, including:
* Scaling and root planing (deep cleaning of the teeth and roots)
* Antibiotics to treat infection
* Bone grafting to restore lost bone tissue
* Gum grafting to cover exposed roots
* Dental implants or prosthetic teeth to replace missing teeth.
It is important to practice good oral hygiene, including brushing and flossing regularly, to prevent periodontitis. Early detection and treatment can help prevent the progression of the disease and save teeth from being lost.
Some common examples of bacterial infections include:
1. Urinary tract infections (UTIs)
2. Respiratory infections such as pneumonia and bronchitis
3. Skin infections such as cellulitis and abscesses
4. Bone and joint infections such as osteomyelitis
5. Infected wounds or burns
6. Sexually transmitted infections (STIs) such as chlamydia and gonorrhea
7. Food poisoning caused by bacteria such as salmonella and E. coli.
In severe cases, bacterial infections can lead to life-threatening complications such as sepsis or blood poisoning. It is important to seek medical attention if symptoms persist or worsen over time. Proper diagnosis and treatment can help prevent these complications and ensure a full recovery.
Plaque is a key risk factor for dental caries (tooth decay) and periodontal disease, which can lead to tooth loss if left untreated. In addition, research suggests that there may be a link between oral bacteria and certain systemic diseases, such as heart disease and diabetes. Therefore, maintaining good oral hygiene practices, such as regular brushing and flossing, is essential to prevent the accumulation of plaque and promote overall health.
Suppuration is a process of pus formation that occurs in response to an infection or inflammation. It is a natural defense mechanism of the body, which helps to eliminate pathogens and protect the surrounding tissues from further damage. Suppuration involves the accumulation of pus, a mixture of dead white blood cells, bacteria, and other debris, within a specific area of the body.
Suppuration can occur in various parts of the body, such as the skin, lungs, and joints, and is typically associated with bacterial or fungal infections. The process of suppuration involves several stages, including:
1. Inflammation: The body's response to an initial injury or infection, characterized by increased blood flow, swelling, redness, and warmth in the affected area.
2. Neutrophil migration: White blood cells called neutrophils migrate to the site of infection and engulf the pathogens, releasing enzymes that help to break down the bacterial cell walls.
3. Bacterial killing: The neutrophils and other immune cells work together to kill the invading bacteria, releasing reactive oxygen species (ROS) and other chemicals that damage the bacterial cell membranes.
4. Pus formation: As the bacteria are killed, the dying cells and their components, such as lipopolysaccharides, are engulfed by the neutrophils and other immune cells. This material is then converted into pus, which is a mixture of dead white blood cells, bacteria, and other debris.
5. Resolution: The suppuration process eventually resolves as the pus is either absorbed by the body or drained through natural openings (such as the skin) or medical intervention (such as drainage).
Suppuration is a natural process that helps to protect the body from infection and promotes healing. However, if the process becomes chronic or excessive, it can lead to complications such as abscesses or sepsis.
