Bacteremia Caused by Staphylococci with Inducible Vancomycin Heteroresistance [PDF]

Clinical Infectious Diseases, 1999
The clinical significance of bacteremia due to vancomycin-heteroresistant staphylococci and a rapid laboratory screening method were examined; 203 strains of staphylococci isolated from patients with clinically significant bacteremia were screened by the disk-agar method with use of vancomycin-salt agar to demonstrate satellitism around an aztreonam ...

Multicenter Study of Colistin Heteroresistance in Carbapenem-Resistant Klebsiella pneumoniae Strains in China

Microbiology Spectrum, 2023
Colistin has been considered a last-line option for the treatment of infections caused by carbapenem-resistant Klebsiella pneumoniae (CRKP). Heterogeneous resistance to colistin leads to unexplained clinical colistin treatment failure for CRKP. Our study

Mechanism of Eravacycline Resistance in Clinical Enterococcus faecalis Isolates From China

Frontiers in Microbiology, 2020
Opportunistic infections caused by multidrug-resistant Enterococcus faecalis strains are a significant clinical challenge. Eravacycline (Erava) is a synthetic fluorocycline structurally similar to tigecycline (Tige) that exhibits robust antimicrobial ...

Heteroresistance Is Associated With in vitro Regrowth During Colistin Treatment in Carbapenem-Resistant Klebsiella pneumoniae

Frontiers in Microbiology, 2022
Polymyxins including polymyxin B and colistin (polymyxin E) are considered the last resort for treating infections caused by carbapenem-resistant gram-negative bacteria.

The highly dynamic nature of bacterial heteroresistance impairs its clinical detection

Communications Biology, 2021
Bacterial populations can show heteroresistance, where an antibiotic resistant subpopulation is part of a susceptible one. Pereira et al. show in Escherichia coli and Salmonella enterica that disk diffusion, a common antibiotic susceptibility test ...

Vancomycin Heteroresistance in Staphylococcus Haemolyticus : Elusive Phenotype

Future Science OA, 2021
To determine the presence of vancomycin heteroresistance in Staphylococcus haemolyticus.A total of 48 rifampicin-resistant S. haemolyticus isolates from bloodstream infections were included. Vancomycin heteroresistance was determined using the population analysis profile-area under curve (PAP-AUC) method. All the isolates were screened for the presence

Fungal Antimicrobial Resistance: Mechanisms, Drivers, and Global Clinical Burden

ChemFoodChem, EarlyView.
ABSTRACT Fungal antimicrobial resistance (AMR) is a growing concern for world health caused by an increase in multidrug‐resistant infections, an increase in environmental reservoirs, and the ineffectiveness of current antifungal treatments. Fungal infections continue to be largely excluded from AMR initiatives while causing over 1.6 million deaths ...

Overexpression of KPC contributes to ceftazidime-avibactam heteroresistance in clinical isolates of carbapenem-resistant Klebsiella pneumoniae

Frontiers in Cellular and Infection Microbiology
Ceftazidime–avibactam (CZA) is one of the effective antibiotics used for the treatment of carbapenem-resistant Klebsiella pneumoniae (CRKP) infections, but its resistance rate has increased recently. Previous studies have focused on the mechanisms of CZA

Heteroresistance to Colistin in Clinical Isolates of Klebsiella pneumoniae Producing OXA-48

Antibiotics, 2023
Heteroresistance to colistin can be defined as the presence of resistant subpopulations in an isolate that is susceptible to this antibiotic. Colistin resistance in Gram-negative bacteria is more frequently related to chromosomal mutations and insertions.
