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.

Anaerobes in pelvic inflammatory disease: implications for the Centers for Disease Control and Prevention's guidelines for treatment of sexually transmitted diseases. (1/1409)

In preparing the 1998 sexually transmitted disease treatment guidelines of the Centers for Disease Control and Prevention, we reviewed evidence regarding the need to eradicate anaerobes when treating pelvic inflammatory disease (PID). Anaerobes are present in the upper genital tract during an episode of acute PID, with the prevalence dependent on the population under study. Vaginal anaerobes can facilitate acquisition of PID and cause tissue damage to the fallopian tube, either directly or indirectly through the host inflammatory response. Use of several broad-spectrum regimens appears to result in excellent clinical cure rates, despite the fact that some combinations fall short of providing comprehensive coverage of anaerobes. There are limited data on the long-term effects of failing to eradicate anaerobes from the upper genital tract. Concern that tissue damage may continue when anaerobes are suboptimally treated has prompted many experts to caution that therapeutic regimens should include comprehensive anaerobic coverage for optimal treatment of women with PID.  (+info)

Comparative in vitro activities of amoxicillin-clavulanate against aerobic and anaerobic bacteria isolated from antral puncture specimens from patients with sinusitis. (2/1409)

By an agar dilution method, the antimicrobial susceptibilities of antral sinus puncture isolates were studied. Pneumococci were generally susceptible to amoxicillin, azithromycin, and clarithromycin, but 17% of pneumococcal isolates were resistant to cefuroxime. Haemophilus influenzae isolates were resistant to amoxicillin and clarithromycin. beta-Lactamase production occurred in 69% of Prevotella species. One-third of Peptostreptococcus magnus isolates were resistant to azithromycin and clarithromycin. Cefuroxime had limited activity against Prevotella species and P. magnus. Levofloxacin was active against most isolates except peptostreptococci. Amoxicillin-clavulanate was active against all isolates, with the MIC at which 90% of the isolates were inhibited being < or = 1 microgram/ml.  (+info)

Molecular cloning, sequencing, and expression of a novel multidomain mannanase gene from Thermoanaerobacterium polysaccharolyticum. (3/1409)

The manA gene of Thermoanaerobacterium polysaccharolyticum was cloned in Escherichia coli. The open reading frame of manA is composed of 3,291 bases and codes for a preprotein of 1,097 amino acids with an estimated molecular mass of 119,627 Da. The start codon is preceded by a strong putative ribosome binding site (TAAGGCGGTG) and a putative -35 (TTCGC) and -10 (TAAAAT) promoter sequence. The ManA of T. polysaccharolyticum is a modular protein. Sequence comparison and biochemical analyses demonstrate the presence of an N-terminal leader peptide, and three other domains in the following order: a putative mannanase-cellulase catalytic domain, cellulose binding domains 1 (CBD1) and CBD2, and a surface-layer-like protein region (SLH-1, SLH-2, and SLH-3). The CBD domains show no sequence homology to any cellulose binding domain yet reported, hence suggesting a novel CBD. The duplicated CBDs, which lack a disulfide bridge, exhibit 69% identity, and their deletion resulted in both failure to bind to cellulose and an apparent loss of carboxymethyl cellulase and mannanase activities. At the C-terminal region of the gene are three repeats of 59, 67, and 56 amino acids which are homologous to conserved sequences found in the S-layer-associated regions within the xylanases and cellulases of thermophilic members of the Bacillus-Clostridium cluster. The ManA of T. polysaccharolyticum, besides being an extremely active enzyme, is the only mannanase gene cloned which shows this domain structure.  (+info)

The in-vitro activity of linezolid (U-100766) and tentative breakpoints. (4/1409)

The in-vitro activity of linezolid, a novel oxazolidinone, was investigated in comparison with those of amoxycillin, cefuroxime, quinupristin/dalfopristin, trovafloxacin and vancomycin against 420 recent Gram-positive and anaerobic clinical isolates. Linezolid was equally active (MIC90 1 mg/L) against methicillin-susceptible and -resistant Staphylococcus aureus. It demonstrated uniform activity against streptococci and enterococci and no cross-resistance with other agents. The time-kill kinetic data demonstrated that the in-vitro activity of linezolid was predominantly bacteriostatic; slow bactericidal activity was only observed at the higher concentration with streptococci. An increase in inoculum from 10(4) to 10(6) cfu on selected strains had little effect on the MICs (MIC90 within one dilution step) of linezolid and an increase in inoculum from 10(5) to 10(7) cfu/mL had no notable effect on the in-vitro bactericidal activity. A tentative linezolid breakpoint of 2 mg/L was chosen after analysis of distribution of susceptibilities.  (+info)

Towards the reaction mechanism of pyrogallol-phloroglucinol transhydroxylase of Pelobacter acidigallici. (5/1409)

Conversion of pyrogallol to phloroglucinol was studied with the molybdenum enzyme transhydroxylase of the strictly anaerobic fermenting bacterium Pelobacter acidigallici. Transhydroxylation experiments in H218O revealed that none of the hydroxyl groups of phloroglucinol was derived from water, confirming the concept that this enzyme transfers a hydroxyl group from the cosubstrate 1,2,3, 5-tetrahydroxybenzene (tetrahydroxybenzene) to the acceptor pyrogallol, and simultaneously regenerates the cosubstrate. This concept requires a reaction which synthesizes the cofactor de novo to maintain a sufficiently high intracellular pool during growth. Some sulfoxides and aromatic N-oxides were found to act as hydroxyl donors to convert pyrogallol to tetrahydroxybenzene. Again, water was not the source of the added hydroxyl groups; the oxides reacted as cosubstrates in a transhydroxylation reaction rather than as true oxidants in a net hydroxylation reaction. No oxidizing agent was found that supported a formation of tetrahydroxybenzene via a net hydroxylation of pyrogallol. However, conversion of pyrogallol to phloroglucinol in the absence of tetrahydroxybenzene was achieved if little pyrogallol and a high amount of enzyme preparation was used which had been pre-exposed to air. Obviously, the enzyme was oxidized by air to form sufficient amounts of tetrahydroxybenzene from pyrogallol to start the reaction. A reaction mechanism is proposed which combines an oxidative hydroxylation with a reductive dehydroxylation via the molybdenum cofactor, and allows the transfer of a hydroxyl group between tetrahydroxybenzene and pyrogallol without involvement of water. With this, the transhydroxylase differs basically from all other hydroxylating molybdenum enzymes which all use water as hydroxyl source.  (+info)

Chemical modification of lysine side chains of cyclodextrin glycosyltransferase from Thermoanaerobacter causes a shift from cyclodextrin glycosyltransferase to alpha-amylase specificity. (6/1409)

Cyclodextrin glycosyltransferases and alpha-amylases are two groups of enzymes with related secondary structures. However, cyclodextrin glycosyltransferases display transferase activities not present in alpha-amylases, probably derived from the existence of two more domains and different amino acid sequences. The hydrolytic activity of cyclodextrin glycosyltransferases is generally quite low, except for two cyclodextrin glycosyltransferases from termophiles. In this work, we have carried out the chemical modification (with acetic anhydride) of the amino groups of cyclodextrin glycosyltransferase from Thermoanaerobacter to assess their contributions to protein function. The acetylated cyclodextrin glycosyltransferase showed a significant reduction of its cyclization, coupling and disproportionation activities. Surprisingly, the hydrolytic (saccharifying) activity was slightly enhanced. These results suggest the participation of one or more lysine side chains in the interactions contributing to the transferase activity, either in any of the S11 subsites or in the acceptor binding site.  (+info)

Current susceptibility patterns of anaerobic bacteria. (7/1409)

While antibiotic resistance among anaerobes continues to increase, the frequency of antimicrobial susceptibility testing for anaerobes is declining. Because anaerobic infections are often mixed and detailed bacteriology of the organisms involved may take some time, physicians must institute empiric therapy before susceptibility testing results are available. Also, economic realities and prudent use of resources mandate that careful consideration be given to the necessity for routine susceptibility testing of anaerobic bacteria. Determination of appropriate therapy can be based on published antibiograms; however, since patterns may vary within geographic regions and even within hospitals, it is strongly recommended that each hospital center periodically test their isolates to determine local patterns and detect any pockets of resistance. As a general guide, antibiograms from the last several years of susceptibility testing at the Wadsworth Anaerobe Laboratory are reported.  (+info)

In vitro antibacterial properties of pexiganan, an analog of magainin. (8/1409)

Pexiganan, a 22-amino-acid antimicrobial peptide, is an analog of the magainin peptides isolated from the skin of the African clawed frog. Pexiganan exhibited in vitro broad-spectrum antibacterial activity when it was tested against 3,109 clinical isolates of gram-positive and gram-negative, anaerobic and aerobic bacteria. The pexiganan MIC at which 90% of isolates are inhibited (MIC90) was 32 micrograms/ml or less for Staphylococcus spp., Streptococcus spp., Enterococcus faecium, Corynebacterium spp., Pseudomonas spp., Acinetobacter spp., Stenotrophomonas spp., certain species of the family Enterobacteriaceae, Bacteroides spp., Peptostreptococcus spp., and Propionibacterium spp. Comparison of the MICs and minimum bactericidal concentrations (MBCs) of pexiganan for 143 isolates representing 32 species demonstrated that for 92% of the isolates tested, MBCs were the same or within 1 twofold difference of the MICs, consistent with a bactericidal mechanism of action. Killing curve analysis showed that pexiganan killed Pseudomonas aeruginosa rapidly, with 10(6) organisms/ml eliminated within 20 min of treatment with 16 micrograms of pexiganan per ml. No evidence of cross-resistance to a number of other antibiotic classes was observed, as determined by the equivalence of the MIC50s and the MIC90s of pexiganan for strains resistant to oxacillin, cefazolin, cefoxitin, imipenem, ofloxacin, ciprofloxacin, gentamicin, and clindamicin versus those for strains susceptible to these antimicrobial agents. Attempts to generate resistance in several bacterial species through repeated passage with subinhibitory concentrations of pexiganan were unsuccessful. In conclusion, pexiganan exhibits properties in vitro which make it an attractive candidate for development as a topical antimicrobial agent.  (+info)

Title: Activities of Quinolones Against Obligately Anaerobic Bacteria. VOLUME: 6 ISSUE: 1. Author(s):R. Schaumann and A. C. Rodloff. Affiliation:Institute for Medical Microbiology and Epidemiology of Infectious Diseases, University of Leipzig,Liebigstr. 24, D-04103 Leipzig, Germany.. Keywords:Quinolones, naphthyridones, anaerobes, aerobe/anaerobe mixed infections. Abstract: Quinolones are of clinical and scientific interest since their discovery based on the nalidixic acid in the early 1960s. They are based on two types of ring structures, the quinolone nucleus and the naphthyridone nucleus. Nalidixic acid as the first discovered agent is a naphthyridone and has only a moderate activity against Gram-negative rods. The modification of the quinolone and naphthyridone structures resulted in increasing activities of the quinolones against Gram-negative, Gram-positive, atypical and obligately anaerobic bacteria and mycobacteria. The quinolones are now divided into four groups due to their different ...
The purpose of this study was to identify anaerobic ammonium-oxidizing bacteria and to support quantitative PCR results which were performed for searching an effective seeding sludge to achieve successful enrichment of anaerobic ammonium-oxidizing bacteria. Eleven sludge-samples originated from ten purification facilities for livestock wastewater were used in this study. At first, six samples among the eleven samples were selected by gas productivity per a gram biomass. The selected samples were used for the experiments of qPCR and 454 pyrosequencing after extraction of the genomic DNAs. The quantitative PCR was done with the primer sets of AMX818F/AMX1066R and HZO2aF/HZO2aR. The amplicons for pyrosequencing analysis were constructed by using the primer-set which is consisted of a specific pla46F primer targeting the conserved 16S rRNA gene belongs to Plantomycetes phylum and eub 518R targeting the conserved 16S rRNA genes of all bacteria. There is no meaningful correlation between the results ...
In general, these bacteria do not require oxygen for their growth and metabolism although some of them (referred to as facultative anaerobic bacteria) are capable of using oxygen when present, and carry out aerobic respiration. Other bacteria (referred to as obligate anaerobic bacteria) can neither use oxygen nor convert the lethal superoxide formed in their cells due to the presence of oxygen. ...
Doripenem, a 1-β-methyl carbapenem being developed for the treatment of serious systemic bacterial infections, is resistant to hydrolysis by dihydropeptidase 1 (7). In aerobes, doripenem appears to have the advantages of both imipenem (in its activity against gram-positive cocci) and meropenem (in its activity against gram-negative organisms) (12). Metalloenzymes that hydrolyze carbapenems have been found in both aerobic bacteria (3, 10, 11) and anaerobic bacteria (2); the gene for the metalloenzyme may be silent or expressed to various degrees, resulting in a wide range of carbapenem resistance levels (13). In Japan, this accounts for the 2 to 4% rate of resistance to imipenem (1, 16), but these isolates are rarely found in the United States. The purpose of this study was to measure the efficacy of doripenem against a wide range of clinical anaerobic isolates and to compare its in vitro activities to those of other antimicrobial agents.. Bacteria were clinical isolates collected from a wide ...
Diagnosis The diagnosis of anaerobic infection is based primarily on symptoms, the patients medical history, and location of the infection. A foul-smelling infection or drainage from an abscess is diagnostic of anaerobic infection. This foul smell is produced by anaerobic bacteria and occurs in one third to one half of patients late in the infection. Other clues to anaerobic infection include tissue necrosis and gas production at the infection site. A sample from the infected site may be obtained, using a swab or a needle and syringe, to determine which bacteria is (are) causing the infection. Because these bacteria can be easily killed by oxygen, they rarely grow in the laboratory cultures of tissue or pus samples. The recent medical history of the patient is helpful in diagnosing anaerobic infection. A patient who has or recently had surgery, dental work, tumors, blood vessel disease, or injury are susceptible to this infection. The failure to improve following treatment with antibiotics that ...

Preliminary test: The concentration of EA-3098 in the aqueous phases after two and three successive centrigugation steps was for peak 1 ,1.0 x 10 -5 g/l, peak 2 ,4.0 x 10-5 g/l and for peak 3 ,1.o x 10-4 g/l, respectively. From this it could be concluded that the water solubility of EA-3098 is ,10 mg/l. Therefore, the column elution method was chosen for the determination of the water solubility of EA-3098. The pH of the aqueous phase after 2 centrifugation steps was 9.5. Main study (column elution method): Analysis confirmed the presence of test substance on the loaded carrier material before filling the column. The eluates did not contain undissolved particles. In the eluates from the blank column a small peak was detected for peak 1. The concentration was calculated using the RF-factor and was ,Limit of Detection (LOD).

Doctors Ask: Anaerobic infections are caused by non-spore-forming anaerobic bacteria (microorganisms that require low oxygen uptake for growth). To extinguish the vital functions of anaerobic bacteria, contact with oxygen, even short-term, is necessary. Therefore, anaerobic microorganisms tend to be located where for their development there are all the appropriate conditions: in the large intestine, genital organs (female), between the gums and the surface of the tooth, etc.
The thermal hydrolysis process (THP) has been proven to be an excellent pretreatment step for an anaerobic digester (AD), increasing biogas yield and decreasing sludge disposal. The goal of this work was to optimize deammonification for efficient nitrogen removal despite the inhibition effects caused by the organics present in the THP-AD sludge filtrate (digestate). Two sequencing batch reactors were studied treating conventional digestate and THP-AD digestate, respectively. Improved process control based on higher dissolved oxygen set-point (1 mg O-2/L) and longer aeration times could achieve successful treatment of THP-AD digestate. This increased set-point could overcome the inhibition effect on aerobic ammonium-oxidizing bacteria (AerAOB), potentially caused by particulate and colloidal organics. Moreover, based on the mass balance, anoxic ammonium-oxidizing bacteria (AnAOB) contribution to the total nitrogen removal decreased from 97 +/- A 1 % for conventional to 72 +/- A 5 % for THP-AD ...
The complexity of the oral and gingival flora has prevented the clear elucidation of specific etiologic agents in most forms of oral and dental infections. In the gingival crevice, there are approximately 1.8 X1011 anaerobes per gram (1). Because anaerobic bacteria are part of the normal oral flora and outnumber aerobic organisms by a ratio of 1 10 to 1 100 at this site, it is not surprising that they predominant in dental infections. There are at least 350 morphological and biochemically.... ...
An imbalance in the colonic microbiota might underlie many human diseases, but the mechanisms maintaining homeostasis remain elusive. Recent insights suggest that colonocyte metabolism functions as a control switch, mediating a shift between homeostatic and dysbiotic communities. During homeostasis, colonocyte metabolism is directed towards oxidative phosphorylation, resulting in high epithelial oxygen consumption. The consequent epithelial hypoxia helps maintain a microbial community dominated by obligate anaerobic bacteria, which provide benefit by converting fiber into fermentation products absorbed by the host. Conditions that alter the metabolism of the colonic epithelium increase epithelial oxygenation, thereby driving an expansion of facultative anaerobic bacteria, a hallmark of dysbiosis in the colon. Enteric pathogens subvert colonocyte metabolism to escape niche protection conferred by the gut microbiota. The reverse strategy, a metabolic reprogramming to restore colonocyte hypoxia, ...

A novel anaerobic, heterotrophic bacterium, designated strain Zn2T, was isolated from the wastewater of a paper mill in Zhejiang, China. Cells were Gram-type-positive rods, 0.5-0.8 µm wide and 2-4 µm long, and were motile by a lateral flagellum. The ranges of temperature and pH for growth were 10-50 °C and pH 6.0-9.5. Optimal growth occurred at 35 °C and pH 7.3-7.5. The strain did not require NaCl for growth, but its inclusion in the medium improved growth (optimum concentration 6 %). Substrates utilized as sole carbon sources were peptone, tryptone, Casamino acids, d-xylose, salicin, glycerol, formate, acetate and propionate. The main products of carbohydrate fermentation were acetate, formate, propionate and lactate. Elemental sulfur, thiosulfate and Fe(III) were used as electron acceptors, but sulfate, sulfite, nitrate, nitrite and Mn(IV) were not. Growth was inhibited by the addition of 10 µg ampicillin, penicillin, tetracycline or chloramphenicol ml−1. iso-C15 : 0, C14 : 0, C16 : 0, C16 : 1

Recent studies indicate that ammonia is an important electron donor for the oxidation of fixed nitrogen, both in the marine water column and sediments. This process, known as anammox, has so far only been observed in a large range of temperature habitats. The present study investigated the role of anammox in hydrothermal settings. During three oceanographic expeditions to the Mid-Atlantic Ridge, hydrothermal samples were collected from five vent sites, at depths ranging from 750 to 3650 m from cold to hot habitats. Evidence for the occurrence of anammox in these particular habitats was demonstrated by concurrent surveys, including the amplification of 16S rRNA gene sequences related to known anammox bacteria, ladderanes lipids analysis and measurement of a (14)N(15)N dinitrogen production in isotope-pairing experiments at 60 and 85 degrees C. Together these results indicate that new deep-branching anammox bacteria may be active in these hot habitats.

The nitrogen removal pathways in anaerobic ammonium oxidation (anammox) process where anaerobic ammonium-oxidizing bacteria and denitrifying heterotrophs convert ammonium and nitrite directly to dinitrogen gas under anoxic conditions were investigated using a mathematical model. The Activated Sludge Model No. 1 (ASM1) was modified with two step denitrification and one-step anaerobic ammonia oxidation. A one dimensional granular biofilm model was implemented in Aquasim 2.1v (EAWAG, Switzerland) in order to describe a series of batch processes operated in a bioreactor treating synthetic wastewater. A sophisticated statistical method was used for parameter estimation. The model was not sensitive with respect to the detachment velocity in the biofilm matrix as well as the porosity coefficients of dissolved state variables. The final results showed a satisfactory goodness of fitness representing Pearson correlation coefficients of 0.96, 0.98 and 0.81 for modeled and measured concentrations of NH4-N, NO2-N

Multiple species of bacteria have been isolated from chronic and acute wounds, including wounds without any signs of infection. A literature review by Bowler examined culture data from 62 published studies dating between 1969 and 1997 (Bowler, 1998). The most predominant isolate was Staphylococcus aureus (reported in 63% of the studies), followed by coliforms (45%), Bacteroides spp. (39%), Peptostreptococcus spp. (36%), Pseudomonas aeruginosa (29%), Enterococcus spp. (26%), and Streptococcus pyogenes (13%).. This literature review also indicated that anaerobic bacteria were more commonly reported isolates from infected wounds. A later culture-based study compared the microflora of chronic and acute wounds (Bowler and Davies, 1999). In this study, Staphylococcus aureus predominated in infected acute wounds, while infected chronic wounds were primarily colonized by anaerobic bacteria (Peptostreptococcus spp., Bacteroides spp., Prevotella/ Porphyromonas spp., Clostridium spp.), coliforms, and fecal ...
Three strictly anaerobic, Gram-positive, non-spore-forming, rod-shaped, motile bacteria, designated strains ACB1(T), ACB7(T) and ACB8, were isolated from human subgingival dental plaque. All strains required yeast extract for growth. Strains ACB1(T) and ACB8 were able to grow on glucose, lactose, maltose, maltodextrin and raffinose; strain ACB7(T) grew weakly on sucrose only. The growth temperature range was 30-42 °C with optimum growth at 37 °C. Major metabolic fermentation end products of strain ACB1(T) were acetate and lactate; the only product of strains ACB7(T) and ACB8 was acetate. Major fatty acids of strain ACB1(T) were C(14 : 0), C(16 : 0), C(16 : 1)ω7c dimethyl aldehyde (DMA) and C(18 : 1)ω7c DMA. Major fatty acids of strain ACB7(T) were C(12 : 0), C(14 : 0), C(16 : 0), C(16 : 1)ω7c and C(16 : 1)ω7c DMA. The hydrolysate of the peptidoglycan contained meso-diaminopimelic acid, indicating peptidoglycan type A1γ. Genomic DNA G+C content varied from 42 to 43.3% between strains. ...
The good guys are the aerobic bacteria; naturally present in waste they produce odorless carbon dioxide (CO2) as they breakdown solids and paper in the wastewater. Aerobic bacteria need lots of oxygen to thrive, thus, given a consistent and large enough supply of oxygen, there would be no odor from the holding tank.. Anaerobic bacteria are the bad guys. These bacteria thrive in the absence of air and produce sulfide gases, which smell bad. Anaerobic bacteria also produce methane and CO2, However, most holding tanks do not have sufficient ventilation and since CO2 is heavier than air the CO2 settles on top of the waste and chokes the aerobic bacteria while providing a prime environment for the anaerobic bacteria.. This process can occur any where standing sewage is standing, on Identity Crisis the possible culprits included the holding tank and the hoses.. Locating Odor Source. Armed with the knowledge of how the head odor is created, I began an investigation into the source. The first and ...

Glycerol is a byproduct of bioethanol and biodiesel production processes and can be converted to more valuable products such as ethanol, butanol, 1,3-propanediol, and 2,3-butanediol by various anaerobic bacteria. In this study, we isolated glycerol-utilizing anaerobic bacteria to obtain ones having a superior ability to produce butanol. By adding acetic and butyric acids into the mineral medium containing glycerol, we could enrich butanol-producing bacteria from a soil sample. Isolates showed ,99% 16S rRNA gene similarities with Clostridium diolis/beijerinckii (group 1), C. butyricum (group 2), C. arbusti (group 3), and Klebsiella oxytoca (group 4). The isolates belonging to group 3 produced up to 12.5 g/L of butanol and the isolates belonging to group 2 produced up to 17.1 g/L of 1,3-propanediol from 30 g/L of glycerol. When glucose was used instead of glycerol, the isolates belonging to group 1 produced 12.0 g/L of butanol and 6.9 g/L of ethanol and the isolate of group 4 produced 21.0 g/L of ...
The intestinal flora is a complex ecosystem consisting of over 400 bacterial species that greatly outnumber the total number of cells making up the entire human body. These metabolically active bacteria reside close to the absorptive mucosal surface and are capable of a remarkable repertoire of transforming chemical reactions. Any orally taken compound or a compound Anaerobic bacteria are the predominant microorganisms in the human GI tract, outnumbering aerobes by a factor of 10,000 to 1. The most abundant and beneficial or benign anaerobes are Bifidobacterium, Bacteroides, Fusobacterium, Clostridium, Eubacterium, Peptococcus and Peptostreptococcus. Bifidobacterium can comprise up to 25% of the total flora in a healthy adult. A great many other species are present, but in lesser numbers.227 An imbalance in proportion and numbers of these species can be induced by broad-spectrum antibiotic use. This leads to the dominance of other bacterial species, including Pseudomonas, Enterobacter, Serratia, ...

In contrast to the well-established roles of microbes in the aetiology of acute sinusitis, the exact roles of the abovementioned microorganisms (namely Prevotella and Porphyromonas spp., Fusobacterium spp., GPAC, V. parvula, L. buccalis, E. corrodens, E. lenta, Bacteroides spp. and Clostridium spp.) in the aetiology of CRS are uncertain [1, 2]. Various researchers disagree on the microbial aetiology of CRS; some of the disagreement may be explained by the different methodological approaches to the processing of the obtained microbiological samples. Many bacterial organisms have been identified in the sinus tracts of patients with CRS and are reported in the literature, but there is no consensus as to their correct pathogenic role. Despite the exact cause of the inflammation associated with CRS is uncertain, the presence of bacteria within the sinuses has been well documented in different studies [9, 10]. Some of these studies have examined the bacterial pathogens associated with CRS, but most of ...

When I present scientific evidence that God designed the creation and that it is not a product of chance, one response that frequently comes from skeptics is that perhaps there is some other way that life and the conditions to support it could exist. Maybe there is life totally different than our kind of life so that the odds diminish because there are different ways and forms that life can take is a common response. In a statement like this one, we have to assume that a scientific proposal is being made-not a religious one. If a person wishes to argue for rock people or fire people, they can do so, but not on a scientific base. Life is generally defined as having the characteristics of moving, breathing, reproducing, and responding to outside stimuli. Things like viruses and anaerobic bacteria are hard to fit into any definition, but Fire people would be even more of a problem. The reason that there is no other way is because of the chemical restraints on all of lifes processes. In order for ...
This post was most recently updated on October 17th, 2018. Specimens for anaerobic culture should be properly collected and transported. Indigenous anaerobes are often present in large numbers as normal flora on mucosal surfaces (e.g. mouth). So the sample from sites known to have anaerobes as part of the normal flora is unacceptable for anaerobic culture. ...
Every year about 40 000 cases of sepsis occur in Sweden, of which three to ten percent (1 200-4 000 cases) are caused by anaerobic bacteria. These bacteria die in the presence of oxygen. Most often, the disease-causing anaerobic bacteria occur in the patients own normal microflora, but in, for example, post-surgery infections, trauma, impaired blood circulation or underlying disease, they can create serious infections that can, in the worst case, lead to death.. Simple mistakes in the sampling of specimens from a patient, or later handling of material collected from an anaerobic infection, may kill the bacteria before they can be detected and identified. Thereby the diagnosis and antimicrobial treatment might be wrong. A serious infection can have a rapid progression that leads to sepsis, so it is very important that the patients receive the right treatment as quickly as possible, says Maria Hedberg, associate professor and biomedical scientist.. She and her company Dianox are located at ...

During January 1994-February 1995, laboratory leaching tests were conducted using crushed shale packed in columns and suspended in shake flasks (slurries). Tests were conducted at ambient temperatures of 20-28oC and over elapsed times of 6 to 39 weeks under three different hydrologic scenarios: variably saturated, aerobic; continuously saturated, stagnant; and continuously saturated, aerobic. Biologically active and sterilized conditions were evaluated to test if specific chemical additives increased or decreased microbial catalysis of acid-forming oxidation reactions. Deionized water was used as the influent when solids, including sewage sludge, N-P-K fertilizer, or CaCO3 were added on top of the shale at the beginning of the experiment. Solutions containing dissolved nutrients (NH3, NO3-, PO43-, or K+) from chloride or sodium salts were added to the shale as the influent in other experiments. Most-probable numbers of iron- and ammonium-oxidizing bacteria and concentrations of chemicals in ...

It is important to differentiate ZD from breast cancer. Patients should be carefully checked to make sure that they do not have breast cancer, which can include having a physical exam, mammogram and ultrasound. In Zuskas disease, breast imaging may show a cystic mass or sometimes multiple cystic masses. A biopsy, or tissue sample may need to be obtained to rule out cancer.. ZD treatment may require antibiotics. Abscesses should be drained when they reach a head. Bacteria that live with and without oxygen (aerobic and anaerobic bacteria) may be isolated in cultures from patients with ZD, with the most common organisms being anaerobic Peptostreptococci together with aerobic Staphylococci. Surgery is the only curative treatment for a lactiferous fistula, a disease tract between the abscess and the breast skin. Core excision of the fistula and all of the associated infected breast tissue is the definitive treatment. Smoking cessation is also essential to help prevent recurrences of ZD.. For more ...
