Shield against microbial growth -

An essential part of this protective outer membrane layer is a molecule called lipopolysaccharide LPS , previous research has revealed. To survive, bacteria cells need a certain amount of LPS — too much or too little kills the cell.

But how bacteria cells determine the right amount remains unclear. Through a series of experiments, they were able to uncover an important part of the LPS regulatory process in E. That newly freed molecule then stimulates the breakdown of the enzyme that initiates LPS production, which ultimately causes LPS production to slow.

The result is a tight regulation of LPS that is essential for keeping E. coli cells alive. Disrupting this regulation, said Mi, would be an effective way to kill bacteria. Fred Mamoun: fred. mamoun yale.

The researchers found that protective communities block the growth of harmful pathogens by consuming nutrients that the pathogen needs. The findings, published today in the journal Science , could help to develop new strategies to optimise gut health. Bacteria cells in the mammalian gut.

A major health benefit these provide is to protect the gut against invading pathogens disease-causing microorganisms that could cause harmful infections. But up to now, how this protective effect comes about has been unclear, and whether certain bacterial species have a more important role than others.

To investigate this, researchers at the University of Oxford tested different gut bacteria strains individually and in combination for their ability to limit the growth of two harmful bacterial pathogens: Klebsiella pneumoniae and Salmonella enterica. Individual gut bacteria showed a very poor ability to restrict the spread of either pathogen.

But when communities of up to 50 species were cultured together, the pathogens grew up to times less effectively than when cultured with any individual species. However, the researchers found that the members of the bacterial communities — and not just the overall diversity — had a critical effect on the level of protection.

Certain species were found to be essential for community-based protection, even though these species offered little protection on their own. The researchers demonstrated that protective bacterial communities block pathogen growth by consuming the nutrients that the pathogen needs.

By assessing the genomes of the different bacterial species, they found that the most protective communities were composed of species with highly similar protein compositions to the pathogenic species. They also used metabolic profiling to demonstrate that the protective species had similar demands for carbon sources as the pathogens.

Certain species that have a crucial role in community protection show a high degree of metabolic overlap with the pathogen, and therefore similar nutrient demands. Nutrient blocking: diverse gut bacteria consume the nutrients that a pathogen needs to invade and block it from the microbiome.

coli strain. When tested experimentally, the communities which had the highest nutrient overlap with the E.

According to the researchers, these new insights could be developed into novel strategies to combat harmful gut pathogens through optimising gut microbiome communities. They may also explain why individuals can become more susceptible to species such as K. pneumoniae after taking antibiotic treatments that can lower the diversity of gut microbiome species.

This gives promise to the goal of optimising the composition of microbiomes to protect against bacterial species that are harmful to health.

Shield against microbial growth so, microorganisms are not always harmful. Since a few years ago, scientists have been deepening in the study of the microbiome, microorganisms that inhabit our body and acts as a second shield. Recent publications highlight, for example, the important role that our gut bacteria play in modifying the response of our body to cancer therapies or toxicity of treatments. This is one of the points that will be discussed during the fourth edition of The Barcelona Debates on the Human Microbiome.
