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.Bacteroidaceae: A family of gram-negative bacteria found primarily in the intestinal tracts and mucous membranes of warm-blooded animals.

They occur in water, soil, and in the intestinal tract of humans and lower animals.Species Specificity: The restriction of a characteristic behavior, anatomical structure or physical system, such as immune response; metabolic response, or gene or gene variant to the members of one species. It refers to that property which differentiates one species from another but it is also used for phylogenetic levels higher or lower than the species.DNA Transposable Elements: Discrete segments of DNA which can excise and reintegrate to another site in the genome. Most are inactive, i.e., have not been found to exist outside the integrated state. DNA transposable elements include bacterial IS (insertion sequence) elements, Tn elements, the maize controlling elements Ac and Ds, Drosophila P, gypsy, and pogo elements, the human Tigger elements and the Tc and mariner elements which are found throughout the animal kingdom.Tetracycline: A naphthacene antibiotic that inhibits AMINO ACYL TRNA binding during protein synthesis.Eubacterium: 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. No endospores are produced. The genus Eubacterium should not be confused with EUBACTERIA, one of the three domains of life.Capnocytophaga: A gram-negative gliding bacterium isolated from the oral cavity. It is a pathogen often causing PERIODONTITIS.Germ-Free Life: Animals not contaminated by or associated with any foreign organisms.Culture Media: Any liquid or solid preparation made specifically for the growth, storage, or transport of microorganisms or other types of cells.

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.  (+info)

Rutin and quercitrin are hydrolysed to quercetin, and robinin is hydrolysed to kaempferol, by faecal flora from healthy subjects. The enzymes required for these hydrolyses, namely alpha-rhamnosidase and beta-galactosidase, were produced by some strains of Bacteroides distasonis; other strains, however, synthesized beta-glucosidase. The last-named enzyme was also elaborated by Bacteroides uniformis and Bacteroides ovatus. All the enzymes were produced constitutively. A cell-free extract of B. distasonis containing beta-glucosidase displayed an enzymic activity of 1 mumol/10 min per 10 mg of protein. ...
Bacteroides spp. are dominant components of the phylum Bacteroidetes in the gut microbiota and prosper in glycan enriched environments. However, knowledge of the machinery of specific species isolated from humans (like Bacteroides uniformis) contributing to the utilization of dietary and endogenous sources of glycans and their byproducts is limited. We have used the cutting-edge nanopore-based technology to sequence the genome of B. uniformis CECT 7771, a human symbiont with a proven pre-clinical efficacy on metabolic and immune dysfunctions in obesity animal models. We have also used massive sequencing approaches to distinguish the genome expression patterns in response to carbon sources of different complexity during growth. At genome-wide level, our analyses globally demonstrate that B. uniformis strains exhibit an expanded glycolytic capability when compared with other Bacteroides species. Moreover, by studying the growth and whole-genome expression of B. uniformis CECT 7771 in response to different

Probiotic yogurts and pills promise better health, but the bacteria we ingest find a complex and challenging environment when they enter our gut. Food sources shift with every meal we eat, and the threat of pathogens is ever-present. In this competitive landscape, theres a clear winner already on the field: the genus Bacteroides makes up 30 percent of the bacteria in the human gut, the single most abundant genus.. "Bacteroides are a successful bacterium in our gut microbiome. By offering metabolic capabilities that humans dont have, it helps us to obtain important nutrients. So why are Bacteroides so resilient?

Bacteroides coprosuis Whitehead et al. 2005 belongs to the genus Bacteroides, which is a member of the family Bacteroidaceae. Members of the genus Bacteroides in general are known as beneficial protectors of animal guts against pathogenic microorganisms, and as contributors to the degradation of complex molecules such as polysaccharides. B. coprosuis itself was isolated from a manure storage pit of a swine facility, but has not yet been found in an animal host. The species is of interest solely because of its isolated phylogenetic location. The genome of B. coprosuis is already the 5th sequenced type strain genome from the genus Bacteroides. The 2,991,798 bp long genome with its 2,461 protein-coding and 78 RNA genes and is a part of the Genomic Encyclopedia of Bacteria and Archaea project.

Bacteroides is a genus of Gram-negative, rod-shaped bacteria. Bacteroides species are non-endospore-forming, anaerobes, and may either be motile or non-motile, depending on the species.[1] The DNA base composition is 40-48% GC. Unusual in bacterial organisms, Bacteroides membranes contain sphingolipids. They also contain meso-diaminopimelic acid in their peptidoglycan layer. Bacteroides are normally commensal, making up the most substantial portion of the mammalian gastrointestinal flora,[2] where they play a fundamental role in processing of complex molecules to simpler ones in the host intestine. As many as 1010-1011 cells per gram of human feces have been reported.[3] They can use simple sugars when available, but the main source of energy is polysaccharides from plant sources. ...
A molecular method, termed hierarchical oligonucleotide primer extension (HOPE), was used to determine the relative abundances of predominant Bacteroides spp. present in fecal microbiota and wastewaters. For this analysis, genomic DNA in feces of healthy human adults, bovines, and swine and in wastewaters was extracted and total bacterial 16S rRNA genes were PCR amplified and used as the DNA templates for HOPE. Nineteen oligonucleotide primers were designed to detect 14 Bacteroides spp. at different hierarchical levels (domain, order, cluster, and species) and were arranged into and used in six multiplex HOPE reaction mixtures. Results showed that species like B. vulgatus, B. thetaiotaomicron, B. caccae, B. uniformis, B. fragilis, B. eggerthii, and B. massiliensis could be individually detected in human feces at abundances corresponding to as little as 0.1% of PCR-amplified 16S rRNA genes. Minor species like B. pyogenes, B. salyersiae, and B. nordii were detected only collectively using a primer ...

Cooperative phenotypes are considered central to the functioning of microbial communities in many contexts, including communication via quorum sensing, biofilm formation, antibiotic resistance, and pathogenesis. The human intestine houses a dense and diverse microbial community critical to health, yet we know little about cooperation within this important ecosystem. Here we test experimentally for evolved cooperation within the Bacteroidales, the dominant Gram-negative bacteria of the human intestine. We show that during growth on certain dietary polysaccharides, the model member Bacteroides thetaiotaomicron exhibits only limited cooperation. Although this organism digests these polysaccharides extracellularly, mutants lacking this ability are outcompeted. In contrast, we discovered a dedicated cross-feeding enzyme system in the prominent gut symbiont Bacteroides ovatus, which digests polysaccharide at a cost to itself but at a benefit to another species.

Bacteroides barnesiae has a size of 0.5-1.4 micrometer wide and 0.8-10.6 micrometer long that is completely anaerobic and grows at temperature of about 37C which does not require oxygen to survive. It has a cellular fatty acids including C15:0 and iso-C15:0 and in cultured media appears to be circular, raised and grayish-white colonies. Bacteroides barnesiae is predominantly found in gastrointestinal tract of humans as well as in vertebrate animals where bile is present. It gives benefits to the host if this bacterium strictly retained in the gut by hindering pathogenic microorganisms from forming colonies in the intestines. Bacteroides barnesiae play a basic role in the breakdown of polysaccharides a complex molecule into small molecules that is used by the bacterium as well as the host in order to utilize the nitrogenous substances and biotransformation of steroids and bile acids. Scientific classification: ...

Because conventional microflora are composed of diverse microbial societies, we asked whether single enteric bacterial species are sufficient to drive small intestinal RegIIIγ expression. As expected, a mixed microbial community recovered from a conventional mouse elicited a ∼20-fold increase in RegIIIγ expression when introduced into germ-free wild-type C57/b6 mice. In contrast, colonization with the Gram-negative symbiont Bacteroides thetaiotaomicron elicited only a 2.5-fold increase in expression, whereas the noninvasive Gram-positive L. innocua had no effect on RegIIIγ mRNA levels (Fig. 4C). These results indicate that neither organism alone was sufficient to stimulate RegIIIγ expression to conventional levels in wild-type mice. However, bacteria that are normally strictly compartmentalized in the intestinal lumen show increased mucosal adherence and invasion in mice that lack mucosal IgA (23). We therefore postulated that mucosal defenses such as secretory IgA might be sufficient to ...

Forty women supplied fecal samples for profiling, and magnetic resonance images were taken of their brains as they viewed images of individuals, activities or things that evoked emotional responses. The women were divided by their gut bacteria composition into two groups: 33 had more of a bacterium called Bacteroides; the remaining seven had more of the Prevotella bacteria. The Bacteroides group showed a greater thickness of the gray matter in the frontal cortex and insula, brain regions involved with the complex processing of information. They also had larger volumes of the hippocampus, a region involved in memory processing. The Prevotella group, by contrast, showed more connections between emotional, attentional and sensory brain regions and lower brain volumes in several regions, such as the hippocampus. This groups hippocampus was less active while the women were viewing negative images. They also rated higher levels of negative feelings such as anxiety, distress, and irritability after ...
Bacteroides, Bacterial Identification and Bacteria Treatment are considered an interesting alternative to the traditional indicator organisms such as E.coli
Bacteroides ovatus is a member of the human gut microbiota. The importance of this microbial consortium involves the degradation of complex dietary glycans mainly conferred by glycoside hydrolases. In this study we focus on one such catabolic glycoside hydrolase from B. ovatus. The enzyme, termed BoMan26A, is a -mannanase that takes part in the hydrolytic degradation of galactomannans. The crystal structure of BoMan26A has previously been determined to reveal a TIM-barrel like fold, but the relation between the protein structure and the mode of substrate processing has not yet been studied. Here we report residue-specific assignments for 95% of the 344 backbone amides of BoMan26A. The assignments form the basis for future studies of the relationship between substrate interactions and protein dynamics. In particular, the potential role of loops adjacent to glycan binding sites is of interest for such studies. ...
Intestinal worms continue to be bad news in most parts of the world, but theyve cohabited with humans for so long that they have evolved to interact with us in complex, even beneficial ways, as a new study published in Science on April 14 reminds us. Led by Deepshika Ramanan from New York University, a team of scientists from the US, Malaysia and Japan worked with mice which had a gene called Nod2 knocked out. Nod2-deficient mice are used as models of inflammatory bowel disease (IBD), a condition that is notably uncommon in developing nations but increasingly prevalent in developed nations.. The scientists found that a type of intestinal cell in the sick mice was defective and resulting in compromised mucus layers lining their guts. These changes in the guts environment caused normal bacterial populations in the gut to fluctuate. One species, Bacteroides vulgatus, was observed to thrive in these IBD mice. Interestingly, B. vulgatus has previously been found in humans with IBD. "However, it is ...

Various subspecies of Bacteroides melaninogenicus differ in their pigmentation. Subsp. asaccharolyticus produces protohaem almost exclusively, subsp. intermedicus both protohaem and a smaller proportion of protoporphyrin, and subsp. melaninogenicus mainly protoporphyrin with a trace of protohaem. As a consequence young colonies can be differentiated by their red fluorescence in u.v. light (365nm): subsp. asaccharolyticus does not fluoresce, subsp. intermedicus shows a limited fluorescence, and subsp. melaninogenicus shows a bright fluorescence. The pigments were isolated as the dimethyl esters of protohaemin and of protoporphyrin and identified by electronic spectroscopy, mass spectrometry and comparisons by t.l.c. Incorporation of delta-aminolaevulinate into these pigments was not detected, nor was porphobilinogen formation observed. Subsp. melaninogenicus grown in the presence of [14C]protohaemin formed [14C]protoporphyrin. This appears to represent a novel biological demetallation. ...
The results of a multicenter US survey using the National Committee for Clinical Laboratory Standards currently recommended methodology for measuring in vitro susceptibility of 2673 isolates of Bacteroides fragilis group species were compared from 1997 to 2000. The test panel consisted of 14 antibiotics: 3 carbapenems, 3 β-lactam-β-lactamase inhibitors, 3 cephamycins, 2 fluoroquinolones, clindamycin, chloramphenicol, and metronidazole. Declines in the geometric mean minimum inhibitory concentrations were seen with imipenem, meropenem, ampicillin-sulbactam, and the cephamycins. Increased geometric means were observed with the fluoroquinolones and were usually accompanied by an increase in resistance rates. Bacteroides distasonis shows the highest resistance rates among β-lactam antibiotics, whereas Bacteroides vulgatus shows the highest resistance levels among fluoroquinolones. B. fragilis shows the lowest resistance rates for all antibiotics. All strains were susceptible to chloramphenicol ...

We report the single-contig genome sequence of the anaerobic, mesophilic, cellulolytic bacterium, Bacteroides cellulosolvens. The bacterium produces a particularly elaborate cellulosome system, whereas the types of cohesin-dockerin interactions are opposite of other known cellulosome systems: cell-surface attachment is thus mediated via type-I interactions whereas enzymes are integrated via type-II interactions. ...
Results One hundred and ninety six patients were recruited: 158 CRC patients, 24 adenoma patients and 14 normal colon controls (median age 70; range 35-90). Tumours were staged as 6 T0, 4 T1, 23 T2, 97 T3, 27 T4; 99 N0, 40 N1, 27 N2; 6 M1. No significant differences were seen in diversity or taxonomy between the UK and Czech cohorts. Adenoma and healthy colon control samples were taxonomically indistinct. However, CRCs were characterised by reduced Shannon diversity (p,0.01), with enrichment of organisms including Bacteroides fragilis,Fusobacterium nucleatum and under-representation of Bacteroides vulgatus,Bacteroides uniformisandFaecalibacterium prausnitzii (all q,0.01). Furthermore, we found a significant progressive reduction in the expression of Bacteroides vulgatus with advancing T stage and a corresponding increase in Fusobacterium nucleatum expression (figure).

In this study, the genetic element flanking the BfPAI in ETBF 86-5443-2-2 and a related genetic element in NCTC 9343 were identified and characterized. The results suggest that these genetic elements are members of a new family of CTns not described previously. These putative CTns, designated CTn86 and CTn9343, for ETBF 86-5443-2-2 and NCTC 9343, respectively, differ from previously described Bacteroides species CTns in a number of ways. These new transposons do not carry tetQ, and the excision and formation of circular intermediates are not regulated by tetracycline; they are predicted to have a different mechanism of transposition; and their sequences have very limited sequence homology with CTnDOT or other described CTns.. Initial alignment results with NCTC 9343 (pattern III) and 638R (pattern II) sequences indicated that CTn9343 was ∼80 kb in length; however, further colony blot hybridizations, PCR, and sequence analysis determined that the real ends of CTn9343 define a genetic element of ...
The pentose phosphate pathway is a process of glucose turnover that produces NADPH as reducing equivalents and pentoses as essential parts of nucleotides. There are two different phases in the pathway. One is irreversible oxidative phase in which glucose-6P is converted to ribulose-5P by oxidative decarboxylation, and NADPH is generated [MD:M00006]. The other is reversible non-oxidative phase in which phosphorylated sugars are interconverted to generate xylulose-5P, ribulose-5P, and ribose-5P [MD:M00007]. Phosphoribosyl pyrophosphate (PRPP) formed from ribose-5P [MD:M00005] is an activated compound used in the biosynthesis of histidine and purine/pyrimidine nucleotides. This pathway map also shows the Entner-Doudoroff pathway where 6-P-gluconate is dehydrated and then cleaved into pyruvate and glyceraldehyde-3P [MD:M00008 ...

Small-subunit ribosomal DNA sequences of 16 strains of Bacteroides fragilis were determined and compared with previously published sequences. Three phylogenetic methods (the neighbor-joining, maximum-likelihood, and maximum-parsimony methods) as well as a bootstrap analysis were used to assess the robustness of each topology. All phylogenetic analyses demonstrated that the B. fragilis strains were clearly divided into two robust monophyletic units which corresponded to the cfiA-negative and cfiA-positive groups. Strains of two previously identified DNA homology groups separated similarly into the two monophyletic units. According to the intensity of the hybridization signal with a cfiA probe, the cfiA-positive cluster could be further divided into two groups. This difference might reflect the existence of two, probably closely related cfiA-type genes. In the strongly hybridizing cfiA-positive strains, the gene is capable of conferring high-level resistance to the carbapenems and to most ...

Summary The presence of capsulate Bacteroides spp. and anaerobic gram-positive cocci was investigated in pus specimens from 182 children with chronic orofacial infections or abscesses and in pharyngeal swabs from 26 children without inflammation. Of 216 Bacteroides spp. and anaerobic cocci isolated from clinical infections, 170 (79%) were capsulate, compared with 34 (35%) of 96 isolates from normal pharyngeal flora (p|0.001). The commonest organisms found to be capsulate more often from infected patients than from controls belonged to the B. melaninogenicus group. The possible evolution of encapsulation in these organisms and their importance in mixed orofacial infections are discussed.

Intestinal bacteria are linked to our diet. When participants in this last Danish study were divided by their level of intestinal bacteria, it was found that people with a high proportion of Prevotella bacteria compared to the bacteria Bacteroides lost 3.5 kg more in 26 weeks, they ate a diet composed of the principles of the "New Nordic Diet" compared to those who consumed a Danish average diet.. Subjects with a low proportion of Prevotella bacteria compared to Bacteroides did not lose any extra weight by following this new Nordic Diet. Overall, about 50% of the population has a high proportion of Prevotella bacteria compared to Bacteroides bacteria.. The study shows that only about half of the population will lose weight if it eats according to the Danish national dietary guidelines - and eats more fruits, vegetables, fiber and whole grains. The other half of the population does not seem to benefit from this change of regime. These people should focus on other feeding recommendations and ...

Trillions of microorganisms inhabit mucosal surfaces of the human body. Despite increasing evidence of their impact on human health, many of the molecular mechanisms underlying hostmicrobial interactions (HMI) are poorly understood. To contribute to our understanding of HMI at mucosal surfaces, we investigated the novel family of M60-like/PF13402 domain-containing proteins and their putative functional partners. M60-like domains are shared by proteins from several mucosal microbes including two important human mucosal microbes; the bacterial mutualist Bacteroides thetaiotaomicron and the protist pathogen Trichomonas vaginalis, suggesting these proteins are important for interaction with the mucosal layer. We initially tested our hypothesis that these are glycoprotein-targeted metal dependent proteases in both these organisms. The three M60-like domains of B. thetaiotaomicron proteins (BT4244, BT3015 and BT4272) exhibited mucin protease activity. This proteolytic activity was shown to be ...

The researchers now plan to expand the application of their tools to different species of Bacteroides. That is because the microbial makeup of the gut varies from person to person, meaning that a particular species might be the dominant bacteria in one patient, but not in others.. "We aim to expand our genetic toolkit to a wide range of bacteria that are important commensal organisms in the human gut," Lu says.. The concept of using microbes to sense and respond to signs of disease could also be used elsewhere in the body, he adds.. In addition, more advanced genetic computing circuits could be built upon this genetic toolkit in Bacteroides to enhance their performance as noninvasive diagnostics and therapeutics.. "For example, we want to have high sensitivity and specificity when diagnosing disease with engineered bacteria," Lu says. "To achieve this, we could engineer bacteria to detect multiple biomarkers, and only trigger a response when they are all present.". Tom Ellis, group leader of the ...
GH105 enzymes do not act via a typical Koshland retaining or inverting mechanism [8], rather the current proposed mechanism of action for these enzymes is hydrolysis through syn-hydration of the double bond between the C-4 and C-5 carbons of the enopyranuronosyl residue of their substrate [5]. This hydration reaction forms a hemiketal that undergoes spontaneous rearrangement to form an intermediate hemiacetyl, which undergoes further rearrangement resulting in the breakage of the bond to the neighbouring saccharide (at the +1 subsite of the enzyme) of the polymer. This mechanism was initially theorized based on the oligosaccharide and amino acid arrangement in a substrate-bound crystal structure [6], but has been confirmed through kinetic isotope effects and NMR analysis in the highly related unsaturated glucuronyl hydrolase GH88 family [3, 9]. The kinetics for three enzymes from the GH105 family have been determined, two from Bacillus subtilis and one from Bacteriodes thetaiotaomicron. YteR ...

Bacteroides species, saccharolytic Gram-negative obligate anaerobes, are frequently isolated from human infections such as peritonitis, abscesses and bacteremia. Among the species in the genus Bacteroides, thespecies called "B. fragilis group" areparticularly involved inhuman infections andaremedically important because they account for a major part of anaerobic isolates from clinical specimens. The purpose of this study was to develop PCR primers that specifically and simultaneously amplify theβ-isopropylmalate dehydrogenase gene leuB in B. fragilis group species. We determined partial nucleotide sequences of leuB genes and compared them in seventeen strains of nine B. fragilis group species, and the regions that are conserved among Bacteroides strains but different from other species were used as a B. fragilis group-specific PCR primer set, BacLBF-BacLBR. Specificity tests of the primer set using 52 phenotypically characterized strains and 75 isolates from rat feces showed only one case each ...
Coloured scanning electron micrograph (SEM) of Prevotella intermedia, Gram-negative, anaerobic, rod shaped, prokaryote (bacterium). Prevotella intermedia is a black pigmented bacterium that was formerly known as Bacteroides intermedius or Bacteroides melaninogenicus. It can coaggregate with other Gram-positive oral bacteria such as Porphyromonas gingivalis and Actinomyces viscosus. P. intermedia is a normal part of the oral and vaginal flora but can cause respiratory infections including aspiration pneumonia, lung abscesses and osteomyelitis. It can also cause gingivitis and other types of oral lesions including vertical bone loss. P. intermedia, along with Porphyromonas gingivalis, are known to cause polymicrobial infections. Prevotella sp. often become resistant to antibiotics, especially tetracycline and penicillin. Magnification: x3,400 when shortest axis printed at 25 millimetres. - Stock Image C032/2243
As the appreciation for anaerobic bacteriology has grown, it has become apparent that the isolation of Bacteroides species from clinical isolates is a significant finding. Studies by Redondo et al. (15) and Nguyen et al. (14) have linked Bacteroides bacteremia to higher mortality rates, which can be further affected by the use of inactive antimicrobials in the treatment regimen.. The class of 5-nitroimidazole drugs (metronidazole, tinidizole, and ornidizole) exerts antimicrobial actions via inhibition of DNA synthesis (19). This action requires intracellular reduction of the nitro group of these prodrugs to produce reactive radical species. Although the 5-nitroimidazole drugs were introduced into clinical practice in 1960, resistance of B. fragilis to these drugs was not described until 1978 (10) and remains rare (1, 20-22). The first metronidazole-resistant Bacteroides isolates were found to have altered end products of glucose metabolism that conferred distinctive biochemical and growth ...
Of 1284 Bacteroides strains collected in Europe in 2000 for antibiotic susceptibility surveillance, 65 isolates displayed imipenem minimum inhibitory concentrations (MICs) , or =1 mg/L and were chosen for a thorough analysis of their resistance mechanism. Twenty-five of the isolates were positive for the cfiA carbapenem resistance gene. The resistance rates were 0.8% and 1.3% for imipenem and meropenem, respectively. In six of the strains, insertion sequence (IS) elements (IS613, IS614B, IS1186 and IS1187) activated the cfiA gene. However, other strains displayed at least elevated carbapenem MICs or were carbapenem resistant and produced measurable carbapenemase activities but did not harbour IS elements in the region upstream of the cfiA gene. The major determinant of carbapenem resistance in Bacteroides fragilis is production of CfiA metallo-beta-lactamase via activation of the cfiA gene by IS elements (higher level resistance) or by activation of its putative own promoter.. ...
Many Bacteroidetes, especially Bacteroides are opportunistic pathogens. The figure shows predominant sites colonized by Bacteroides and other anaerobic bacilli. Their levels are higher in celiac disease and more severe forms of IBS (Rome III criteria). Prevotella, and Fusobacterium are prevalent in the body and usually dont cause problems, but may become involved in infections throughout the body (see Fig.). Within the Bacteroides group, B fragilis is the most common pathogen, followed B thetaiotaomicron and other members of the B fragilis group. Among the bile-sensitive Prevotella species, the ones most commonly encountered clinically are P melaninogenica, P oris, and P buccae. Porphyromonas species seem to be much less pathogenic except in dental infections. Fusobacterium nucleatum is the Fusobacterium species most often found as a pathogen, but F necrophorum occasionally produces serious disease. Several species of Flavobacteria are known to cause disease in freshwater fish. Bacteria that ...
Bacteroides fragilis is a Gram-negative member of the normal human gut microbiota. The Bacteroidetes constitutes one of the major bacterial phyla in the healthy human gut [1]. However, B. fragilis is also an important opportunistic pathogen, and it is the most frequently isolated anaerobic bacterium in clinical specimens, including abdominal abscesses and bloodstream infections [2]. Indeed, while B. fragilis accounts for only 4 to 13% of the normal human fecal microbiota, it is responsible for 63 to 80% of Bacteroides infections [3]. Only a few virulence factors have been described for B. fragilis, with the best characterized being the polysaccharide (PS) capsule [4] and a secreted metalloprotease, fragilysin [5]. The capsule, which displays antigenic variation, promotes the formation of abscesses [4], and the reduction of pro-inflammatory responses to B. fragilis[4, 6]. The metalloprotease fragilysin, which has been linked to diarrheal disease [5], has activity against the zonula junctions ...

We were able to assemble a single chromosome of 5.18 Mb, with no gaps, using publicly available software and commodity computing hardware. We identified gene rearrangements and the state of invertible promoters in the strain. |br| The final assembly and annotations are available from the public archives (EBI/NCBI/DDBJ) and additionally here we provide the assemblies done for comparison from each of the individual technologies and the alignments of the original raw reads to the final assembly.|br|
Bacteroides fragilis is an obligately anaerobic bacterium that can be isolated from a variety of human infections (2). In the mid-1980s it was recognized that some strains produce an enterotoxin (ET) that can cause acute diarrhea in humans, young lambs, calves, pigs, and foals (6,7). Enterotoxigenic B. fragilis (ETBF) strains have also been isolated from the feces of children with diarrhea (9). Kato et al. (4) showed that B. fragilis blood culture isolates were more likely to be ETBF and suggested that ETBF strains are more virulent than enterotoxin-negative strains. Recently, the enterotoxin gene of B. fragilis has been cloned, sequenced, and identified as producing a zinc metalloprotease of 44.4 kDa (5).. In order to determine the relative frequency of ETBF in different geographic locations, 93 B. fragilis clinical isolates from Germany and Southern California were analyzed. Two PCR assays were used to detect two independent genetic sequences of the B. fragilis enterotoxin gene. In addition, ...
This domain of about 175 to 200 amino acids is found, in from one to five copies, in over 50 proteins in Fibrobacter succinogenes S85, an obligate anaerobe of the rumen. Many members of this family have an apparent lipoprotein signal sequence. Conserved cysteine residues, suggestive of disulfide bond formation, are also consistent with an extracytoplasmic location for this domain. This domain can also be found in small numbers of proteins in Chlorobium tepidum and Bacteroides thetaiotaomicron ...
The enumeration of phages infecting host-specific strains of Bacteroides has been widely recognised as an effective and low-cost method of microbial source tracking (MST). A recently described human-specific Bacteroides host strain (GB-124) has been shown to detect bacteriophages exclusively in human-impacted waters and is emerging as a useful MST tool. However, a better understanding of the morphology and ecological behaviour of the phages, especially in wastewater disinfection processes, is now required in order to validate their role as MST markers. Bacteriophages infecting Bacteroides fragilis GB-124 (n = 21) were isolated from wastewater effluent and irradiated using laboratory-based UV-C (254 nm) collimated beam experiments. Bacteriophages were found to be both a morphologically and ecologically homogeneous group, with all specimens showing highly similar first order log-linear inactivation profiles (mean fluence required to inactivate phages by 4-log10 was 36 mJ/cm2). These findings ...
Microbiota. The development and function of the intestinal immune system is influenced by the gut microbiota, including bacteria with the capacity to induce specific lineage differentiation in immune cells. Germ-free mice have an underdeveloped intestinal immune system, signifying a role for MAMPs in its establishment (21). Some commensal bacteria such as segmented filamentous bacteria (SFBs) preferentially induce a Th17 response in T cells (22, 23). Other commensals or their products guide an IL-10 Treg response. The capsular polysaccharide-A moiety on Bacteroides fragilis promotes expansion of Foxp3+ Tregs through a TLR2/MyD88 mechanism (24), while Clostridium species can induce Treg formation independent of MyD88, potentially through TGF-β (25). Bacterial metabolites like short-chain fatty acids (SCFA) produced by Akkermansia muciniphila and Faecalibacterium prausnitzii also influence immunity. For instance, butyrate from these organisms increases the differentiation of Tregs in the colon ...

Rural communities within low-income countries frequently rely on a range of drinking-water sources, and each water source varies in its potential for biological contamination. The extent and source of biological contamination in primary drinking sources within Kien Svay, Kandal, Cambodia, were determined by fecal indicator bacteria (FIB) measurements, 16S rDNA genetic markers for human and bovine fecal Bacteroides, presence of the bloom-forming Microcystis species, and the microcystin toxin mcyD gene marker. Thirteen wells, 11 rain barrels, 10 surface-water sites, and five sediment samples were examined during the dry and wet seasons. Surface water was commonly contaminated with FIB, with up to 1.02 × 105 Enterococcus sp., 6.13 × 104 E. coli, and 2.91 × 104 total coliforms per 100 mL of water. Human and bovine Bacteroides were detected in 100 and 90% of the surface water samples, respectively. Concentrations of FIB in rain-barrels varied by site, however 91% contained human Bacteroides. ...
Bacterial infections of mammalian hosts are arguably among the most complex biological processes, often comprising a multitude of interacting organisms from different kingdoms. How do bacterial pathogens promote infection and what defense mechanisms do they have to overcome in order to colonize? What molecular mechanisms manifest the protective role of the microbiota against pathogenic attack? And what is the role of noncoding RNAs in host-microbiota-pathogen crosstalk? These and related questions are addressed in our group. Using cutting-edge RNA-sequencing-based techniques, our research centers on the identification and functional characterization of noncoding RNA molecules in the enteric pathogen Salmonella Typhimurium, the important intestinal microbiota member Bacteroides thetaiotaomicron, and the human host, to identify those RNAs that may serve as biomarkers for diagnosis or as therapeutic targets in the future. In addition to contributing to the field by the development of novel ...

The taxonomy of the anaerobic bacteria is in a state of continuous change due to the constant addition of new species and the reclassification of the old1. An example of this would be the genus Bacteroides. This genus previously included most of the saccharolytic pigmented species that are now included in the genus Prevotella and the asaccharolytic species which have been assigned to the genus Porphyromonas ...
The bacteria produce compounds, called cephalosporinases, which inactivate and destroy certain antibiotics such as penicillin derivatives and cephalosporins, protecting themselves and other beneficial bacteria that live in close proximity. However, they may also give protection from these antibiotics to harmful bacteria, such as Salmonella.. The gut is home to hundreds of trillions of bacteria, which have important roles in maintaining our health. But a side effect of taking antibiotics is that these may also kill off some of our beneficial gut bacteria, allowing harmful bacteria to gain a foothold and cause an infection. Susceptibility to antibiotics isnt uniform in the hundreds of species that colonise our guts, and some of the most common bacteria, the Bacteroides, are among the most resistant.. By scanning the genome of strains of Bacteroides bacteria that live in the gut, the researchers found genes that produce an enzyme called cephalospoprinase, which specifically destroys certain ...
GH105 enzymes do not act via a typical Koshland retaining or inverting mechanism [8], rather the current proposed mechanism of action for these enzymes is hydrolysis through syn-hydration of the double bond between the C-4 and C-5 carbons of the enopyranuronosyl residue of their substrate [5]. This hydration reaction forms a hemiketal that undergoes spontaneous rearrangement to form an intermediate hemiacetyl, which undergoes further rearrangement resulting in the breakage of the bond to the neighbouring saccharide (at the +1 subsite of the enzyme) of the polymer. This mechanism was initially theorized based on the oligosaccharide and amino acid arrangement in a substrate-bound crystal structure [6], but has been confirmed through kinetic isotope effects and NMR analysis in the highly related unsaturated glucuronyl hydrolase family GH88 [3, 9]. The kinetics for three enzymes from the GH105 family have been determined, two from Bacillus subtilis and one from Bacteriodes thetaiotaomicron. YteR ...

Prevotella intermedia (formerly Bacteroides intermedius) is a gram-negative, obligate anaerobic pathogenic bacterium involved in periodontal infections, including gingivitis and periodontitis, and often found in acute necrotizing ulcerative gingivitis. It is commonly isolated from dental abscesses, where obligate anaerobes predominate. P. intermedia is thought to be more prevalent in patients with noma. P. intermedia use steroid hormones as growth factors, so their numbers are higher in pregnant women.[citation needed] It has also been isolated from women with bacterial vaginosis.

AU - Wu, Shaoguang. AU - Oh, Hee Bok. AU - Sears, Cynthia Louise. PY - 1999/11. Y1 - 1999/11. N2 - Enterotoxigenic Bacteroides fragilis (ETBF) strains, which produce a 20- kDa zinc metalloprotease toxin (BFT), have been associated with diarrheal disease in animals and young children. Studying a collection of ETBF and nontoxigenic B. fragilis (NTBF) strains, we found that bft and a second metalloprotease gene (mpII) are contained in an ~6-kb pathogenicity island (termed B. fragilis pathogenicity island or BfPAI) which is present exclusively in all 113 ETBF strains tested (pattern I). Of 191 NTBF strains, 100 (52%) lack both the BfPAI and at least a 12-kb region flanking BfPAI (pattern II), and 82 of 191 NTBF strains (43%) lack the BfPAI but contain the flanking region (pattern III). The nucleotide sequence flanking ...
We identified enterotoxigenic Bacteroides fragilis in stool specimens of patients with inflammatory bowel disease and other gastrointestinal disorders. The organism was detected in 11 (13.2%) of 83 patients with inflammatory bowel disease. Of 57 patients with active disease, 19.3% were toxin positive; none of those with inactive disease had specimens positive for enterotoxigenic Bacteroides fragilis gene sequences.
Significantly more reads were assigned to the Bacteroidetes phylum in the experimental sample (36%) as compared to the control sample (8.2%). At the class level, Bacteroidia (1.3% in the control sample vs. 24.4% in the experimental sample) and Sphingobacteria (1.1% in the control sample vs. 7.8% in the experimental sample) contributed to higher percentages of the microbiota in the experimental sample than in the control sample. The significant elevation of Bacteroidetes in the intestinal community of the starved seabass sample is in agreement with some other studies [2, 34, 35] on dietary shifts. For example, in mice [34], fasting was associated with a significant increase in the proportional representation of the Bacteroidetes [from 20.6% (fed) to 42.3% (fasted)]. Bacteroides with a much larger genome size (e.g., Bacteroides fragilis Strain NCTC9343: 5,205,140 bp) are normally mutualistic in the animal gastrointestinal flora. A large part of the proteins made by the Bacteroides genome are able ...
Humans excrete between 50 to 100 mg of volatile phenols per day, predominantly in the form of 4-cresol and phenol (mainly as glucuronide and sulfate conjugates) with lower amounts of 4-ethylphenol (20). The production of cresols from tyrosine in mammals has been attributed to various species of Clostridium, Bifidobacterium, and Bacteroides fragilis. Other bacteria such as E. coli are associated with phenol production. Altered levels of 4-cresol metabolites in human urine have been associated with diverse physiological and pathological conditions from weight loss to inflammatory bowel disease. These conditions are also associated with altered microbiota composition, namely a reduction in the diversity of the microbiota because of loss of Lactobacillus and Bacteroides species in the case of inflammatory bowel disease (21) and differences in the ratio of the Firmicutes to Bacteroidetes species in the case of weight loss (22).. Dietary fiber (complex carbohydrates) can be digested and subsequently ...
New York, Aug 9 (IANS) Women consuming high-fat diet during pregnancy may increase the risk of affecting bacteria living in her babys gut thus impacting proper development of the immune system, says a study. The results showed that expecting mothers diets can lead to distinct changes in their babies microbiome, which could affect energy extraction from food as well as early immunity development.. "Diet is very amenable to change and women are highly motivated to make healthy changes during pregnancy. Traditionally, dietary interventions during pregnancy have focused on micronutrients, such as iron and folic acid," said Kjersti Aagaard, Associate Professor at Baylor College of Medicine in the US. Further, a high-fat diet in the mothers was also significantly associated with fewer numbers of bacteroides microbes in the infants microbiome both in samples taken shortly after birth and at four to six weeks of age.. Bacteroides are involved in breaking down and extracting energy from certain ...

Restriction endonuclease analysis showed that 4 of the recombinant plasmids carried a 6.7 kbSphI fragment. Recloning experiments showed that the fimbrial subunit gene was located within a 2.5 kbEcoRI-SphI fragment and that there was aPstI site located within the structural gene or its regulatory region. These recombinant clones will prove useful for the construction of a multivalent recombinant vaccine for the control of ovine footrot.. ...
The gut microbiome is a highly complex microbial community that strongly impacts human health and disease. The two dominant phyla in healthy humans are Bacteroidetes and Firmicutes, with minor phyla such as Proteobacteria having elevated abundances in various disease states. While the gut microbiome has been widely studied, relatively little is known about the role of interspecies interactions in promoting microbiome stability and function. We developed a biofilm metabolic model of a very simple gut microbiome community consisting of a representative bacteroidete (Bacteroides thetaiotaomicron), firmicute (Faecalibacterium prausnitzii) and proteobacterium (Escherichia coli) to investigate the putative role of metabolic byproduct cross feeding between species on community stability, robustness and flexibility. The model predicted coexistence of the three species only if four essential cross-feeding relationships were present. We found that cross feeding allowed coexistence to be robustly maintained for
Summary An agglutination assay for detecting intermicrobial adherence between the cells of Candida albicans and various oral bacteria is described. Strains of Streptococcus sanguis, S. salivarius, S. mutans, S. mitis, Fusobacterium nucleatum and Actinomyces viscosus all coagglutinated with C. albicans. No interaction could be demonstrated between the cells of Bacteroides melaninogenicus and those of C. albicans. Preliminary investigations of these interactions suggest that binding of F. nucleatum and A. viscosus to C. albicans is mediated by bacterial proteins, possibly lectins. Other mechanisms must account for the binding of oral streptococci to C. albicans. The possible implications of these findings in relation to oral mucosal colonisation and oral candidal clearance are discussed.
Definition, Etiology, PathogenesisTop. A brain abscess is a focal infection of the brain parenchyma. It spreads directly by continuity or via a hematogenous route (even from remote primary foci, such as the endocardium). An early inflammatory infiltrate disintegrates after ~2 weeks, forming a reservoir of purulent material enclosed in a thin, well-vascularized capsule that is surrounded by a zone of cerebral edema. Etiology varies with the location of the primary site of infection as well as other risk factors: 1) Sinusitis: Aerobic or anaerobic streptococci, Haemophilus spp, Bacteroides spp, Fusobacterium spp, Streptococcus anginosus.. 2) Otitis media or mastoiditis: Streptococci, aerobic gram-negative intestinal bacilli (particularly Proteus spp), Bacteroides spp, Pseudomonas aeruginosa.. 3) Endocarditis: Viridans-group streptococci.. 4) Trauma: Staphylococcus aureus.. 5) Impaired cell-mediated immunity: Fungi Candida spp, Aspergillus spp, rarely Cryptococcus neoformans; in patients with AIDS ...
A 68-year-old Japanese man with alcoholic liver cirrhosis was admitted to our hospital because of fever and haematemesis. On day 3, his blood culture became positive for Gram-negative bacilli and Gram-positive cocci, and contrast-enhanced abdominal CT revealed acute septic thrombophlebitis of the superior mesenteric vein with caecal diverculitis. Antimicrobial therapy with ampicillin-sulbactam and anticoagulant therapy were started and the blood culture grew Bacteroides fragilis and Streptococcus intermedius. On hospital day 7, the patients condition began to improve in response to the therapy, therefore, the ampicillin-sulbactam and anticoagulant therapy was continued for 42 days. The patient was discharged home on hospital day 45.

Background Ruminococcus flavefaciens is a predominant cellulolytic rumen bacterium, which forms a multi-enzyme cellulosome complex that could play an integral role in the ability of this bacterium to degrade plant cell wall polysaccharides. Identifying the major enzyme types involved in plant cell wall degradation is essential for gaining a better understanding of the cellulolytic capabilities of this organism as well as highlighting potential enzymes for application in improvement of livestock nutrition and for conversion of cellulosic biomass to liquid fuels. Methodology/Principal Findings The R. flavefaciens FD-1 genome was sequenced to 29x-coverage, based on pulsed-field gel electrophoresis estimates (4.4 Mb), and assembled into 119 contigs providing 4,576,399 bp of unique sequence. As much as 87.1% of the genome encodes ORFs, tRNA, rRNAs, or repeats. The GC content was calculated at 45%. A total of 4,339 ORFs was detected with an average gene length of 918 bp. The cellulosome model for R.
