In your gut: How bacteria survive low oxygen environments
Researchers from ITQB NOVA, in collaboration with the Institut Pasteur in Paris, have shed light on the mechanisms that allow Clostridioides difficile, a pathogen that can only grow in oxygen-free environments, to survive low oxygen levels. C. difficile is a major cause of intestinal problems associated with the use of antibiotics, causing an estimated number of 124k cases per year in the EU, costing on average 5k€ per patient, as a direct consequence of healthcare-associated contagion.
