Antibiotics fight infections but disrupt gut bacteria, potentially allowing harmful species like Enterococcus faecium to thrive.
Antibiotics and intestinal flora
Antibiotics are essential for fighting certain bacterial infections. However, they do not target only the bacteria responsible for the disease; they also alter the intestinal flora.Role of intestinal flora
The bacterial diversity within this flora plays an essential role in supporting our immune system and overall health. This ecosystem of microorganisms helps with digestion, nutrient absorption, and protecting against harmful pathogens.Risk of dangerous bacteria
Reducing this diversity can create more space for potentially dangerous species. This is particularly the case with Enterococcus faecium, a bacterium capable of causing difficult-to-treat infections.Research on antibiotic impact
To study this phenomenon, researchers from NYU Langone Health, City of Hope, and other institutions have conducted studies highlighting the impact of antibiotic use on gut microbiota. These studies aim to understand how changes in the gut's bacterial composition can affect health.Need for further research
Some reports indicate that the changes in intestinal flora can lead to an increased risk of infections and other health complications, while others emphasize the need for further research to fully understand the long-term consequences.
