With bacteria managing to defeat antibiotics faster than we can develop drugs, North American researchers have had the idea of looking at the flora of our intestinal microbiota to look for natural proteins to use in the fight against diseases.
By studying the gut microbiomes of 1,773 people, researchers discovered — among some 100 trillion microbes — 78 proteins that hold promise as future antibiotics. Synthesized and then tested in the laboratory, 70.5% of them are capable of fighting bacteria.
One of the most promising proteins is called ” prevotelline-2 ” and shows himself capable of destroying bacteria in ways comparable to those of polymyxin Bone of the most widely used antibiotics currently in patients who develop resistance to several other drugs.

Towards new molecules to kill superbugs?
While there is still much work to be done to convert these proteins into truly effective antibiotics, these initial results are very promising and suggest that the human intestinal microbiota is most certainly home to many other future antibiotics capable of helping us deal with the antibiotic resistance crisis that is worsening year by year.
Moreover, in conducting their research, the scientists discovered other proteins that have antimicrobial properties but are not assembled at the molecular level like our usual antibiotics. These could pave the way for the design of new molecules that kill superbugs.
In the meantime, these discoveries show us once again how our intestinal bacteria are a huge asset in fighting infections. The opportunity to reread our file on the thousand and one ways to take care of your intestines and our article on the most effective probiotics to favor.

Antibiotic Resistance: The Solution is in Our Intestinal Microbiota?
With the alarming rise of antibiotic-resistant bacteria, researchers are racing against time to develop new and effective antibiotics. In this quest, North American scientists have turned their attention to the human gut microbiota, which may hold the key to unlocking novel and natural antimicrobial solutions.
Searching for Natural Antibiotics in the Gut Microbiota
By studying the gut microbiomes of 1,773 individuals, researchers have identified 78 proteins with promising antimicrobial properties [[1]]. These proteins, synthesized and tested in the laboratory, show remarkable efficacy in fighting bacteria, with 70.5% of them displaying antibacterial properties.
One of the most promising proteins, prevotelline-2, has shown impressive antibacterial capabilities, comparable to those of polymyxin B, a widely used antibiotic in patients with multidrug-resistant infections. This breakthrough raises hopes for the discovery of novel antibiotics that can combat the growing problem of antibiotic resistance.
The Gut Microbiota: A Treasure Trove of Antimicrobial Compounds
The human gut microbiota is home to trillions of microorganisms, many of which produce antimicrobial compounds as a defense mechanism against rival bacteria. By tapping into this vast reservoir, researchers may uncover new and innovative ways to combat antibiotic-resistant bacteria.
The Impact of Antimicrobial Use on the Gut Microbiota
However, the overuse of antibiotics can have devastating effects on the gut microbiota, leading to dysbiosis and the emergence of antibiotic-resistant bacteria [[1]]. The misuse of antibiotics in agriculture and human medicine has contributed to the proliferation of antibiotic-resistant genes in the gut microbiome [[2]], further exacerbating the antibiotic resistance crisis.
A New Frontier in Antibiotic Development
The discovery of novel antimicrobial proteins in the gut microbiota opens up new avenues for the development of innovative antibiotics. These proteins, unlike traditional antibiotics, may not be assembled at the molecular level, offering a fresh approach to designing molecules that can combat superbugs [[3]].
Conclusion
The solution to the antibiotic resistance crisis may lie within us – specifically, in our intestinal microbiota. By harnessing the antimicrobial potential of the gut microbiota, researchers may uncover novel and effective antibiotics to combat the growing threat of antibiotic-resistant bacteria. As we continue to navigate the complex landscape of antimicrobial resistance, the role of the gut microbiota in fighting infections cannot be overstated.

Antibiotic Resistance: The Solution is in Our Intestinal Microbiota?
The ongoing struggle against antibiotic resistance has led researchers to explore unconventional solutions. One such approach is to investigate the human intestinal microbiota as a potential source of natural proteins that can combat diseases. This innovative strategy has shown promising results, and this article will delve into the latest discoveries and implications.
The Search for Natural Antibiotics
The human gut microbiome is home to trillions of microorganisms, including bacteria, viruses, and fungi. These microorganisms play a vital role in maintaining our overall health, and researchers have long suspected that they might hold the key to developing new antibiotics. By studying the gut microbiomes of 1,773 people, scientists have identified 78 proteins with antimicrobial properties that could be used to combat bacteria [1].
One of the most promising proteins is prevotelline-2, which has been shown to be capable of destroying bacteria in ways comparable to the widely used antibiotic polymyxin B [2]. This breakthrough has significant implications for the development of new antibiotics, as it offers a potential solution to the growing problem of antibiotic resistance.
The Impact of Antibiotics on the Gut Microbiome
Antibiotics can have a devastating impact on the gut microbiome, leading to a reduction in species diversity, altered metabolic activity, and the enrichment of antibiotic-resistant genes [2[2]. This can disrupt the delicate balance of the microbiome, making us more susceptible to infections and diseases.
Towards New Molecules to Kill Superbugs?
While the initial results are promising, there is still much work to be done to convert these proteins into truly effective antibiotics. However, the discovery of these antimicrobial proteins has opened up new avenues for research. Scientists are now exploring the possibility of designing new molecules that can kill superbugs, paving the way for a potential solution to the antibiotic resistance crisis.
The Importance of the Intestinal Microbiota
The human intestinal microbiota is a vast, untapped resource that has the potential to revolutionize our approach to fighting diseases. By harnessing the power of the microbiome, we can develop new, more effective antibiotics that can combat the growing threat of antibiotic resistance.
