Opportunistic infections caused by antibiotic-resistant bacteria have become a serious global public health issue.
The gastrointestinal tract is a reservoir for opportunistic pathogens or pathobionts that benefit from dysbiosis by proliferating in predisposed patients before causing an infection.
The genus Enterococcus is a commensal of the gastrointestinal (GI) tract of humans and animals. Some species, particularly Enterococcus faecalis and Enterococcus faecium, are opportunistic pathogens that are harmless in healthy individuals. In vulnerable patients (such as immunocompromised and elderly individuals), they can cause severe infections, especially after antibiotic treatment
In the last 30 years, enterococci have been considered the third most common cause of opportunistic infections in fragile patients worldwide
