Characterization of vancomycin resistance in Enterococcus faecium and Enterococcus faecalis

Antimicrobial Agents and Chemotherapy, 1989
Vancomycin resistance in Enterococcus faecium 180, a clinical isolate from England, was studied. Resistance to vancomycin was transferable by conjugation to other enterococci. Expression of resistance was inducible and coincided with the appearance of a new membrane protein.

Enterococcus faecalis mevalonate kinase [PDF]

Protein Science, 2004
AbstractGram‐positive pathogens synthesize isopentenyl diphosphate, the five‐carbon precursor of isoprenoids, via the mevalonate pathway. The enzymes of this pathway are essential for the survival of these organisms, and thus may represent possible targets for drug design.

Multi‐Targeting Carnosic Acid Kills Drug‐Resistant Helicobacter pylori With Narrow‐Spectrum Activity

Advanced Science, EarlyView.
Carnosic acid selectively eradicates drug‐resistant Helicobacter pylori through a multi‐targeted mechanism involving urease inhibition, membrane disruption, and biofilm eradication. It exhibits no detectable resistance, potent in vivo efficacy, and minimal impact on gut microbiota, positioning it as a promising narrow‐spectrum lead compound against ...

Mechanisms for Photoinactivation of Enterococcus faecalis in Seawater [PDF]

Applied and Environmental Microbiology, 2012
ABSTRACT Field studies in fresh and marine waters consistently show diel fluctuations in concentrations of enterococci, indicators of water quality. We investigated sunlight inactivation of Enterococcus faecalis to gain insight into photoinactivation mechanisms and cellular responses to photostress.

Subversion of Atypical Mucin Traps by a Spore‐Coat Effector Blocks Cellular Immunity in Drosophila

Advanced Science, EarlyView.
While the entomopathogenic fungus Metarhizium robertsii can evade insect humoral immunity, its subversion of cellular defenses is still elusive. We identify Eac1 as a spore‐coat protein essential for infecting drosophilids by targeting atypical mucins (Sgf1 and Sgf2), which can entrap spores in a gel matrix and thereby facilitate hemocyte encapsulation.

The population-level impact of Enterococcus faecalis genetics on intestinal colonization and extraintestinal infection [PDF]

, 2023
Enterococcus faecalis is a commensal bacterium of the human gastrointestinal tract that causes opportunistic infections. The E. faecalis genetic changes associated with pathogenicity, particularly gut-to-bloodstream translocation, remain poorly ...
