Every individual has a specific microbial population, which is different from any other individual
.
Each is composed of different bacteria, fungi and viruses, which are present on all surfaces of the body-skin, mucous membranes, and especially the gastrointestinal tract
B?rbel Stecher is Professor of Medical Microbiology and Hygiene at the Max von Pettenkov Institute of the University of Munich and a member of the German Institute for Infection Research (DZIF)
.
Her research focuses on the role of gut microbes in controlling infections
The importance of cooperation
Facts have proved that the key factor is the competition for resources between species
.
"In particular, we found that competition for various sugars in the gastrointestinal tract can explain the inability of Salmonella to colonize the intestine," Stecher explained
However, to effectively eliminate Salmonella, E.
coli usually needs help
.
The new research also shows that E.
Research strategy
"Using synthetic bacterial populations, we can build a model microbiome," Stecher explained
.
The microbiota consists of 12 types of bacteria, all of which are present in the intestines of healthy mice
In order to translate these findings into humans, Börbel Stecher plans to study the bacterial consortium in the human gut microbiota
.
"In a way, our work can help develop treatments, such as probiotic cocktails that support the maintenance of a healthy microbiome
