Perhaps countries as Belgium, Germany, the UK and the Netherlands should cooperate to work towards a solution more effectively. Can you tell more about the facility or history of this lab, and where the research can be obtained? Hey Thanks for sharing!
Do you have a link to this? Thank you. There was a BBC documentary about the laboratory in Tbilisi Georgia many years ago, possibly as long as 25 or 30 years ago. Maybe you could ask them to look into their archive? It was fascinating and I have always since wondered why we never heard any more about it.
This research is needed. I lost my father because of pnemoniae , antibiotic made him feel slighlty okey. Am I the only 12 year old here? This is a very intriguing subject though…. Quite interesting, very neat like quantum mechanics and a real world threat.
Nope, me too. Once bacteria become antibiotic-resistant which some already have phage therapy will be cruical. Investigation to development of bacteriophage to specifically attack P. Many reputable science materials suppliers sell plaque assays from which you can purify your own batch of phages. Make sure you research which bacterial strain corresponds to it before you purchase the phage however, as they are highly specific killers as mentioned in the article. Here are a few sites to hit:.
Do your own research here though. How would someone in the Uk get the correct phage for an infection? Angela Rippon reported on phages on a shocking TV program this week about antibiotic resistance.
It would be so useful to be able to have a link to a lab in Georgia or elsewhere in Eastern Europe where the work is done. One interviewer had been receiving the phages from Georgia for years. Wrong, viruses CAN work on eukaryotic cells as that is how viral infections like influenza work. I am unsure if it can cure cancer though because even if a virus was developed to target cancer, it may attack your good cells as well because they share the same genetic info.
This is very interesting though and needs some research done on it. Yes, viruses in general can affect eukaryotic cells, but this whole article is about bacteriophages literally meaning bacteria-eaters. Bacteriophages target ONLY prokaryotic cells such as bacteria. This may speed up the process.
Petitions too Change — Momentum may help. I have put forward Proposals for Research NIH via the Charities but feel too bothered about funding themselves as no replies. Cystic fibrosis patients live everyday taking antibiotics with no alternative therapy. They have several bacterial infections in one patient. Surely they would be prime candidates for phage therapy research. For Gods sake , hurry up with the science. They have never ending supplies of thick sticky mucous to experiment with.
Get on with it. Interesting story on that on wired. Rather, in America capital dominates, and anything that affects making money and profits is bad. Pharmaceutical companies make billions of dollars off of antibiotics.
If they allowed for phage therapy research to make gains, it would encroach on their profits from antibiotics. I am scared to death of loosing my leg if this bacterial infection is not controlled. I was on a 8 week regime of Vancomycin through a pick line it did not help. My Dr. I am sorry to hear of your situation and would love to help. But I am just a lowly high school student with no college education.
I would think there would be treatment options involving phages for your infection, especially of an infection of your caliber.
Good luck. Respond if you get better. I am retired 20 yrs from routine work in NHS and just have just found phages interesting. They are worthy of research and developement for general use. There is a great need to replace antibiotics which are becoming , have become,useless in many cases There is Graham Hatfull at Pittsburg and there is a US navy commander who has a large number of phages. I have read that San Diego university medical centre treated Tom Patterson suffering from multi-resistant acineto bacter infection this year.
His wife Stephanie Staffadee has made a video on this TEDx talks i think Good luck i hope your problem has been solved now. Whats the point removing dead bacteria bodies before injecting phages into the body? There would be dead bacteria bodies anyways if the phage kills bacterium inside the body. Would that not also cause sepsis. No as your white blood cells, namely phagocytes, could engulf and break down the dead bodies before harm can be done.
I would like to if, phage therapy could be expanded on. Also, how would the sepsis work? If Sepsis is dead bacteria, then how would the bits of dead bacteria in our body do to us? I have mycobacterium progressively eating cavities in my lung 9mm sized , I am relatively young and otherwise healthy, but I am told antibiotics are not likely to work, I had recently had a washing of my lungs to get an accurate diagnosis of the strain of bacteria.
I am keen to know more about Phages. It is a Georgia Pharmacy that also do diagnostic lab tests to identify the many different bacterial pathogens that causes infections and then they create an individual bacteria phage that that will kills that particular bacterial pathogen that is causing the infection. I have known about Phages for years and was very disappointed they are not available to many antibiotic sufferers for last resort treatment.
Many people have died needlessly without the chance of being treated by this safe bacteria. Long ago it was used on people who were infected with Cholera… It is a safe method to fight antibiotic resistance but it takes a bit longer to use and not as easy as a pill to swallow but that is OK if your loved one does not die. One issue that has been left unsaid is that phages do in fact mutate.
The same as bacteria do and that is the very reason a bacteria can become immune to an antibiotic. But the thing left unsaid is that the FDA has approved the use of phages being sprayed on foods.
Finally, problems related to the formulation and stabilization of pharmaceutical preparations for clinical use are far from solved Vandenheuvel et al. In this regard, it has to be highlighted that studies seem to indicate that stability of preparations for clinical use is strictly BP dependent and stabilization strategies should be optimized for each BP separately Clark, ; Merabishvili et al. This can lead to costly and time-consuming clinical trials that could discourage the pharmaceutical industry from starting research and production of preparations for human use.
Emergence of bacterial resistance against BPs is potentially possible, as bacteria possess or can develop several mechanisms to prevent viral infections. Among these are hiding, change or loss of receptor, secretion of substances that prevent phage adhesion to the bacterial pathogen, activation of measures for blocking phage DNA injection into the cell and inhibition of phage replication and release Seed, Alteration or loss of receptor for membrane protein modifications has been demonstrated for E.
Secretion of extracellular polymeric substances and glycoconjugates has been described for Pseudomonas spp. Development of bacterial resistance to BPs can be reduced with the use of BP cocktails, with the administration of a higher initial BP inoculum or the association with antibiotics. If BPs kill pathogens faster than they can replicate, a high inoculum is associated with a lower risk of development of BP-resistant bacteria. Lysogenic phages incorporate their DNA into the bacterial genome.
Consequently, they might be vehicles for horizontal exchange of genetic material and play a role in the diffusion of antibiotic resistance genes ARGs. However, the real contribution of phages to the diffusion of ARGs is not precisely defined. Most of the studies specifically planned to measure how often phages encode ARGs have suggested that these viruses are reservoirs of ARGs. Moreover, diffusion of ARGs can be significantly favored by the presence in the environment of phage inducers, i.
Treatment of wastewater samples with EDTA or sodium citrate activates the lytic cycle of lysogenic phages and leads to the generation of new phage particles, bacterial lyses, phage release outside the cell, and infection of a greater number of bacteria Colomer-Lluch et al. Finally, great numbers of phages carrying genes associated with antibiotic resistance have been detected in secretions and tissues of patients who suffer from recurrent infections due to antibiotic resistant pathogens and had been previously repeatedly treated with antimicrobial drugs.
One of the best examples in this regard is CF, as evidenced by the study conducted by Fancello et al. This and similar findings led to the supposition that BPs might be vehicles for the adaptation of bacteria to the CF lung environment and for the emergence and selection of multidrug-resistant pathogens with chimeric repertoires Rolain et al.
However, a recent reevaluation of previously collected data has suggested that AGR abundance in phages was vastly overestimated and that the risk of transduction, although possible, is lower than previously thought. In several studies, conclusions were misled by the excessive bacterial DNA content of the studied samples. Moreover, inadequate approaches to detect ARGs in phage genomes have been used Enault et al. Partially in agreement with these findings were Lekunberri et al.
The human-associated viromes did not carry or rarely carried ARGs, while those deriving from non-human sources harbored a significantly higher prevalence of ARGs. Bacteriophages and their products are non-self-antigens, and it is not surprising that they can be recognized by the immune system and induce responses that can theoretically reduce the benefit of BP administration. Immune response to BPs has been demonstrated in both experimental animals and humans, although with differences according to the phage strain, the route of administration and the prior exposure.
As phage titres remained stable in the B-cell-deficient mouse, the greatest part of phage clearance from blood seemed to be due to specific antibody production Srivastava et al. However, even if not fully demonstrated, it seems likely that the immune response evoked by phages has a marginal or no impact on the potential bacterial killing of phage administration. Bacterial lysis occurs before a specific antibody is evoked. Moreover, with some exceptions, phage administration was generally not associated with tissue damage, an increase in pro-inflammatory cytokines or increased reactive oxygen species ROS production Park et al.
Miernikiewicz et al. Similar findings were reported by Hwang et al. Carmody et al. On the other hand, data collected in humans that seem to indicate that BP administration is safe seem to support that, even if present, the immune response to BPs is not clinically important. Use of BPs to overcome the problem of increasing microbial resistance to antibiotics is attractive, and some research data seem to indicate that it might be a rational measure.
To date, properly designed clinical trials specifically planned to evaluate BP efficacy are very few and partially negative. Moreover, the problem of how to prepare the formulations for standardized and clinical use in bacterial control, how to avoid or limit the risk of emergence of bacterial resistance and the transmission of genetic material are not completely solved problems.
In addition, the mechanisms concerning coevolution between BP and bacteria are unknown. NP and SE contributed to writing the manuscript. ES performed the literature review. All authors approved the final submitted version of the manuscript. The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest. Abedon, S.
