vancomycin antibiotic that is commonly used to treat infections caused by Enterococcus. While it is broad-spectrum and can affect other bacteria, it has been shown to have a relatively low impact on Bifidobacterium. Another option may be linezolid, which is also effective against Enterococcus and has been shown to have less impact on certain beneficial gut bacteria.
There are several antibiotics that are effective against enterococci while sparing other beneficial gut bacteria like Bifidobacterium. Some examples include:
Ampicillin/sulbactam: This combination antibiotic is effective against many strains of enterococci but tends to have a lower impact on Bifidobacterium populations.
Linezolid: This antibiotic is effective against both vancomycin-resistant and vancomycin-sensitive enterococci, but does not significantly disrupt Bifidobacterium populations.
Daptomycin: This antibiotic is effective against enterococci and has a lower impact on Bifidobacterium populations compared to some other antibiotics.
