Elastase and matrix metalloproteina- ses MMPs responsible for ECM destruction are the neutro- phil derived proteases, which are secreted when there is an inflow of neutrophils in the pressure ulcer [48].

There is an uneven protease secretion and rise in collagenase, gelatinases MMP- 2 and MMP-9 in the wound fluid of pressure ulcers when related to normal healing wounds [50]. Delayed wound heal- ing of diabetic patients is another medical case in which biofilm is held responsible. Though microorganisms involved are numerous but S.

When the mucous membrane covering the paranasal sinuses gets irritated, it results in sinusitis or rhinosinusitis. Ample amount of evidences revealed the biofilm as the main reason behind chronic rhinosinusitis especially the bacterial biofilms, though the role of fungi is still not clear [52]. Ventricular associated pneumonia VAP is another serious issue which draws a special attention. There is a rise in death rate of patients having VAP where fungal species Candida have been detected alone or in the respiratory secretion when equated with patients where only bacteria is isolated.

It is the yeast in combination with bacteria that provides the platform for multi-species biofilm and promotes the viru- lence of multidrug resistant bacteria in the VAP [53].

Mucosal layer of gastrointestinal Gl tract is loaded with loads of good bacteria forming hale and hearty biofilms [54]. Situ- ation starts becoming problematic when these bacteria are sited in feeding tube of the patients with percutaneous endoscopy gastronomy PEGor in the large intestine of person suffering with ulcerative colitis [55].

Medically, this results in diarrhea or, in the worst case, cause sepsis when microbes move through the epithelial membrane. Urinary tract is another place loaded with useful and varied metagenome, which helps to combat against yeast infections, urinary tract infections UTIsexually transmitted disease STD and bacterial vaginosis [57].

Selective inhibition of new species is arbitrated by high acid of lactic acid bacteria. Relapses are measured as the ability of microorganisms to form biofilm [51]. Candida species are also linked with cystitis, prostatitis and pyelonephritis.

Acute pyelonephritis occurs when bacteria infect the renal parenchyma. Infection may ascend from lower urinary tract to kidney through blood.

Acute bacterial prostatitis is caused due to chronic and dominant UTI with the involvement of Proteus mirabilis, Klebsiella, E. Though it is rare but aspergilloma have been detected in urinary tract. Cosmetic surgery is also not untouched by the infections of microbial biofilms.

Cosmetic surgery is surely an interme- diate way for those people who are unfortunate to have a desired body profile. Being a miracle in the history of medi- cine, cosmetic surgery has helped to get rid of wrinkles by inserting botolinum toxin Botoxwhich paralyses nerves responsible for wrinkles and the volume of soft tissue can be increased by injecting gel fillers. Based on material being used and time duration, there are three main types of fillers i.

Nodules, lumps, cysts formation, hardening of tissues and sterile abscesses are the sure outcome of using fillers of different types [63]. All types of fillers were able to shelter biofilms without any kind of obstructive plan.

Studies have confirmed about the che- motaxis regulated biofilm formation in tissue filler injection. Control of biofilms Rigorous, regular and aggressive antibiotic treatment against severity of prolonged biofilm infection may seem promising at first sight but cannot exterminate completely because of the presence of persister cells [64].

Advancement in medical science has flooded with new and improved medical devices and artificial prostheses for curing many human diseases. As the science has advanced and so our biofilm producing microbial community just to keep in pace with the constant changing era. This draws our special attention as it is very difficult and challenging to eradicate biofilm infection. Before proceeding to a battle against biofilm, we must separate our approach and examine whether a foreign body is involved or not.

If a foreign body is involved then, either removal of material from the body is only possible and most fruitful way so as to avoid any further complications, or lessening of biofilm with prolonged biofilm oppressive che- motherapy should be applied.

If a foreign body is not involved then a set of high doses with several superior killing effect antimicrobials should be administered for quite a long time.

Presence of foreign body heavily attracts the chances of biofilm infection by providing a supreme and perfect surface comment bien maigrir apres une grossesse attachment whereas the host polymorphonuclear leuko- cyte capability surrender due to foreign body [65].

For instance, in the absence of any foreign body, S. It is almost impossible to get rid of biofilms with usual antibiotic the- rapy; therefore, it is advised to remove the implanted devices to avoid any other biofilm infection. High dose of oppressive antibiotics are administered where the implanted foreign device cannot be replaced or removed just to saddle the biofilm infection.

To treat a biofilm infected dialysis catheter or central venous catheter CVCfirst and foremost thing is to replace the catheter and ensure a short span of periodic antibiotic dose to eradicate the bacteria passed into blood from that infected catheter. This procedure is followed as a lock therapy when replacement of catheters is momentarily not possible. Likewise, infected urinary catheters may cause urosepsis if not replaced in proper time. Though it is not difficult to replace the urinary catheters but the timing is crucial.

It is strongly advised to replace the infected urinary catheters after 48 hours of sufficiently aggressive but continuous anti- microbial treatment. If not performed cautiously, new Uri- nary Catheter UC would soon be infected by biofilm forming bacteria. Another issue is the loosening of joint prostheses due to biofilm formation.

It can be resolved to some extent by the staged exchange of the fitted prostheses blended with powerful antibiotic application. As already explained that for biofilm-infected prostheses, their complete replacement is the only possible and feasible way to get rid of the infection. Cardiac inefficiency, recurrent sepsis and contagious embo- lic are the usual problems found in endocarditis suffering people with pacemaker or artificial heart valve [69].

There- fore, it becomes mandatory to replace the infected heart valves and pacemaker followed by effective antibiotic action [70]. This same kind of procedure including removal of infected device and antibiotic management is followed when biofilm infections are diagnosed in chronic osteomyelitis dead bonesbiliary and urinary stones, endotracheal tubes and biliary stents.

It has been shown that early stage biofilm can be simply controlled and removed with the application of antibiotic. Flowever, the situation is not simple as it looks like. Most of the clinical infections caused by biofilm are in their later or matured stage when diagnosed and also the initial judgment of biofilm infection is presently challenging. By the time comment perdre le poids en 2 semaines find and realize that it is a biofilm infection, it is always late.

Following are the few important points that should be consi- dered for an effective antibiotic application. Antibiotic selection criteria High sensitivity with high penetration power should be an obligatory condition for that antibiotic that is supposed to be applied on biofilm infections. This determines its minimal concentration for efficient treatment at infection site. It has been observed that the infiltration power of lincosamides, quinolones, tetracyclines, macrolides, rifamycins, fusidic acid, sulfonamides, oxazolidinones and nitroimidazole in biological living tissue and cell is far superior to aminogly- cosides, polymyxin, glycopeptide and beta-lactam compris- ing carbapenems, penicillins, cephalosporins [71].

As the infection proceeds, it causes swelling and redness, which promote higher metabolism and substantial decline in local oxygen content. There might be a significant chance of acidosis via glycolysis, if oxygen demand is not fulfilled.

This results in low pH value, which lowers the influence of beta- lactam antibiotic and upsurge the influence of rifamycin SV. This implies that we should thoroughly look into pH related impacts before selecting any antibiotic for treating biofilm infection. Application of antibiotics For a better result, combination treatment of antibiotics is always prescribed rather than monotherapy or single treat- ment [72].

This is further aided by application of treatment for the appropriate duration of time. In addition, the conti- nuous dose of these antibiotics should fall under secure limit of hepatic and renal performance [73]. General antibiotic treatment along with relevant or specific treatment can give better result in shorter duration of time. For example, to the point application or breathing of antibiotic in biofilm infec- ted air route shows promising results.

Pharmacodynamics PD and pharmacokinetics PK of antibiotics As the availability of efficient antibiotics are very narrow, this increases the concern about its proper use to elevate the post-application results on infection. One way to forecast the maximum effectiveness of antimicrobial course of the- rapy is to determine its pharmacodynamics and pharmaco- kinetics versus infections.

Pharmacodynamics and pharmacokinetics contour of antimicrobial are entirely dif- ferent for infection caused by biofilm producing microbes and their free-floating counterparts [74,75]. Therefore, PD and PK data can be used extensively for dose control in biofilm contamination. There are two governing factors for determining PD i. A detailed and clear result of antimicrobial regimens is achieved when biofilm producing microbes are employed in clinical vulnerability examination with minimum biofilm eradication concentration and minimum biofilm inhibitory concentration.

In a PK vs. PD study performed on bacterial biofilm in vivo, slaying based on concentration was shown by colistin and time contingent slaying was reflected by imipe- nem [77]. Scientific outlook of biofilm control Before onset of biofilm production, the microorganism need to adjust according to their surroundings and revise their functional parameters.

Overall supervision in fungi and bac- teria is performed by population-dependent quorum sensing which directs the expression of genes that determine the microbial pathogenicity [78]. Recently, nucleotide signaling has emerged as a center of curiosity in which nucleotide acts 28 P. Nucleotide signaling manages the virulence capability and mechanism for adaptation in bacteria as that of quorum sensing.

From the above-mentio- ned nucleotides, cyclic di-guanosine monophosphate c-di- GMP is accountable for biofilm production in gram-negative bacteria [80].

Thus, for designing a chemical to restrict biofilm, it must block the two most important factor involved in biofilm formation, i. In addition to quorum sensing and c-di-GMP, there is another point which has drew many attention.

It is the bacterial amyloid that might open new channels to control bacterial biofilms as it serves as communication messenger among many species to adhere the surface and to each other for biofilm creation [81].

Finding new ways for the destruction of bacterial amyloid will surely be a boon to the human health. Targeting quorum sensing QS inhibitors and anti-QS peptide Many quorum sensing molecules are found guilty in the regime anti urticaire of biofilms like acyl homoserine lactones AHLs in gram-negative bacteria, autoinducer peptides AlPs hired by Gram-positive bacteria and auto-inducer-2 AI2 molecu- les derived from 4,5-dihydroxy-2,3-pentanedione DPDwhich mediate as interspecies signals by both gram-negative and gram-positive bacteria [82].

Thus, intervention with these QS molecular pathway will surely bring down the biofilm progression. It was also demonstrated that in vivo application of quorum sensing targeted furanones obtained from plants successfully lowered the lung infection by P.

Meta-bromothiolactone not only shield the lung epi- thelia and Caenorhabditis elegans but also crowned to be most efficient compound to restrict the production of biofilm as well as a pathogenic element called pyocyanin.

Chemicals like azithromycin, furanones and ginseng are known to boost the immunity and antibiotic effect in P. In fact, as QS opposing regimens, azithromycin is positively preferred for cystic fibrosis patients. For prosthe- ses related biofilms, amalgamation of daptomycin and a quorum sensing inhibitor 'FS3' showed positive inhibitory results on staphylococcal vascular graft contamination in a rat model thereby displaying a concerted effect than their individual influence.

Therefore, it can be conclu- ded that QS inhibitors equally escalate the proneness of gram-positive and gram-negative bacteria to antimicrobials. Surprisingly, at a higher density, Streptococcus mutans can induce a self-slaying by releasing a natural QS peptide called competence stimulating peptide.

In spite of the secretion of competence stimulating peptide, an equi- valent KBI is also produced by different streptococcus species which helps in reduction of biofilm manufacture. Modifying c-di-GMP Scientists and researchers all over the world have unani- mously agreed on the role of c-di-GMP as the common most bacterial secondary messenger.

Many processes like transi- tion of motile to sessile form to bring about the existence of multi-populated biofilm, scattering of bacteria from a mature biofilm, exopolysaccharide synthesis and the make-over from pathogenic essentials of acute contamination to chronic contamination with reduced pathogenicity is mediated by c-di-GMP. Therefore, alteration of c-di-GMP signaling path- way seems to be a fruitful and attractive option for the eradication of biofilm development [85].

It was the Palys group who first visualized and recognized four novel anti-DGC molecules which displayed drastic damaging effects on both Acineto- bacter baumannii and P. On a good note, two out of these four molecules are shown to be perfectly safe on eukaryotic cells and this feature can be exploited for biofilm control in the near future [86].

Few molecules were ascertained based on differential radial capillary action of ligand array that are proficient to obstruct the allosteric binding site of c-di-GMP. Ebselen is known to hinder DGC performance and a selenone equivalent of ebselen known as ebselen oxide also hampers the DGC activity by covalently modifying cysteine residues, causing the blockage of c-di-GMP-receptor binding [87]. Thus, these molecules greatly reduce the biofilm in P. Destruction of bacterial amyloid Presence of functional amyloid fibers on many bacterial cell surfaces and their involvement in biofilm production is a verified fact now.

Curli is an extracellular amyloid fiber present onf. Biosynthesis of curli is restricted in E. FN targets the curli and type I pili that are much needed in biofilm formation. Blending of FN with E. Restricting the growth of amyloid-like fibers in Bacillus subtilis has shown a negative effect on its biofilm development [89]. This upshot can be achieved by two bioactive particles i.

In other bacterial species secreting amy- loid fibers, AA preclude TasA protein that bring into the functional amyloid like fibers and parthenolide being a natural artifact has a negative impact on biofilms [90]. Conclusion The intrinsic property of microorganisms to lead a sessile lifestyle is invariably related to its aptitude to form Advanced acuity in microbial biofilm genesis, clinical infections and control 29 unmanageable biofilms and show recurrent infection and resistance to antibiotics.

Advanced scientific observations have let us know about the underlying mechanism of biofilm development and authenticated a relation with clinical infections. Scanning through electron microscopy has unco- vered many mysteries about the involvement of biofilms in pitiable wound cure, pressure ulcers, UTI relapses and conta- mination in many medical prostheses. There are still few shortcomings of in vitro experiments that have to be focused seriously like failure to withdraw the plasma proteins of host, which can contribute the biofilm growth, shortage of clinically avai- lable in vivo assays.

Though many processes and few unusual molecules have been identified as a potential anti-biofilm agent, still there exists a huge scope of improvement bet- ween the continuous fight of cure and infection.

Amyloid fibers provide structural integrity to Bacillus subtilis biofilms. Arf ça me fait super plaisir! Bonne année à toi aussi poulette! Quel gâchis! Le trio Felicity, Diggle, Oliver est vraiment exquis sous tous les regards. Désolée …. Les fans les massacreraient! Pfiou, que dire sur cette série? Je ne vais pas épiloguer, je suis fan. En plus, tu couches entre temps avec son meilleur pote, qui meurt ou pas…. Matt Bomer était trop sex en plus! On zigouille par un mais deux Merlyn. Nan mais allô oui je sais encore?

Malcolm, il pouvait pas attendre un peu avant de nous le dézinguer? Alors certes le suspense est à son comble mais je suis assez déçue du résultat final. Vivement la saison 2 pour nous réparer tout ça. Oh oui Tommy! Mais de toutes façons ils ne suggèrent pas que Roy meurt dans le final! Et je ne pensais vraiment pas marquer ce point avec Arrow!

Mais aussi celles que je ne […]. Il y en a eu des tas. Danny Rand peut fortement faire penser à Oliver Queen Arrow. Ainsi après Arrow et The Flash, CW a décidé de piocher dans les personnages secondaires des deux séries pour nous […]. Et puis je les ai trouvés toujours intéressants et la plus part du temps très touchants. Depuis que son personnage de Arrow est enfermé sur une île, mon gladiateur préféré Spartacus me manque follement… En plus […].

Forcément un spin off ça ne peut que me faire frétiller!
