Fecal carriage of vanB antibiotic resistance gene affects adipose tissue function under vancomycin use

Gut Microbes, 2022
Detrimental consequences of antibiotic treatment may include long-lasting disruption of the gut microbiota. Previous studies found no negative effects of antibiotics on metabolic health, although individualized responses were observed.

Evaluation of the Xpert vanA / vanB Assay Using Enriched Inoculated Broths for Direct Detection of vanB Vancomycin-Resistant Enterococci [PDF]

Journal of Clinical Microbiology, 2014
ABSTRACT Rapid and accurate detection of VRE (vancomycin-resistant enterococci) is required for adequate antimicrobial treatment and infection prevention measures. Previous studies using PCR for the detection of VRE, including Cepheid's Xpert vanA / vanB assay, reported accurate ...

Heterogeneous expression of glycopeptide resistance in enterococci associated with transfer of vanB [PDF]

Antimicrobial Agents and Chemotherapy, 1997
In mating experiments using a clinical strain that constitutively expresses vanB-encoded glycopeptide resistance, resistance transfer was detectable at a frequency of <10(-7) transconjugants/donor. Vancomycin MICs for transconjugants were 2- to 10-fold lower than those for the donor; both inducibly and constitutively resistant transconjugants were ...

735. Vancomycin-Resistant vanB- and vanA/vanB-type Enterococcus faecium Causing Invasive Infections in Adult Patients in Chile

Open Forum Infectious Diseases, 2023
Abstract Background Vancomycin-resistant enterococci has increased globally in recent decades, with Enterococcus faecium (VREfm) being the most prevalent species. Although the prevalence of VREfm in Chile is high (∼70%), its molecular epidemiology is not well-described.

Dissemination and genetic analysis of the stealthy vanB gene clusters of Enterococcus faecium clinical isolates in Japan

BMC Microbiology, 2018
Background VanB-type vancomycin (VAN) resistance gene clusters confer VAN resistances on Enterococcus spp. over a wide range of MIC levels (MIC = 4–1000 mg/L).

Epidemiology, treatment and outcomes of bloodstream infection due to vancomycin-resistant enterococci in cancer patients in a vanB endemic setting

BMC Infectious Diseases, 2020
Background Vancomycin-resistant enterococcus (VRE) is an important cause of infection in immunocompromised populations. Few studies have described the characteristics of vanB VRE infection.

Chemotranscriptomic Profiling Defines Drug-Specific Signatures of the Glycopeptide Antibiotics Dalbavancin, Vancomycin and Chlorobiphenyl-Vancomycin in a VanB-Type-Resistant Streptomycete

Frontiers in Microbiology, 2021
Dalbavancin, vancomycin and chlorobiphenyl-vancomycin share a high degree of structural similarity and the same primary mode of drug action. All inhibit bacterial cell wall biosynthesis through complexation with intermediates in peptidoglycan ...
