Activity of daptomycin against Listeria monocytogenes isolates from cerebrospinal fluid.

abstract：:Vancomycin-resistant enterococci (VRE) are endemic in health care settings. These organisms colonize the gastrointestinal tract and can lead to infection which is associated with increased mortality. There is no treatment for VRE colonization. We conducted a randomized, double-blind, placebo-controlled clinical trial ...
