Epidemiology, mechanisms, and clinical impact of bacterial heteroresistance

npj Antimicrobials and Resistance
Bacterial heteroresistance, a phenomenon where subpopulations within a bacterial strain exhibit significantly reduced antibiotic susceptibility compared to the main population, poses a major challenge in managing infectious diseases.

Impact of time to appropriate therapy on mortality in patients with vancomycin-intermediate Staphylococcus aureus infection [PDF]

, 2016
Despite the increasing incidence of vancomycin-intermediate Staphylococcus aureus (VISA) infections, few studies have examined the impact of delay in receipt of appropriate antimicrobial therapy on outcomes in VISA patients.

Helicobacter pylori and Its Antibiotic Heteroresistance: A Neglected Issue in Published Guidelines

Frontiers in Microbiology, 2019
“Heteroresistance” is a widely applied term that characterizes most of the multidrug-resistant microorganisms. In microbiological practice, the word “heteroresistance” indicates diverse responses to specific antibiotics by bacterial subpopulations in the

Revisiting susceptibility testing in MDR-TB by a standardized quantitative phenotypic assessment in a European multicentre study [PDF]

, 2017
Objectives Treatment outcome of MDR-TB is critically dependent on the proper use of second-line drugs as per the result of in vitro drug susceptibility testing (DST).

Indications of carbapenem resistance evolution through heteroresistance as an intermediate stage in Acinetobacter baumannii after carbapenem administration Indicações da evolução da resistência ao carbapenem através da heteroresistência como estágio intermediário no Acinetobacter baumannii após administração de carbapenem

Revista do Instituto de Medicina Tropical de São Paulo, 2009
We describe an in vivo evolution of an antimicrobial profile from susceptibility to full-resistance to carbapenems, with heteroresistance as an intermediate stage, in an Acinetobacter baumannii strain.

The epidemiology, pathogenesis, transmission, diagnosis, and management of multidrug-resistant, extensively drug-resistant, and incurable tuberculosis. [PDF]

, 2017
Global tuberculosis incidence has declined marginally over the past decade, and tuberculosis remains out of control in several parts of the world including Africa and Asia.

The dynamic distribution of genetic tandem amplifications in a heteroresistant Escherichia coli population revealed by ultra-deep long read sequencing

Nature Communications
Antibiotic heteroresistance, characterized by rare resistant subpopulations of bacteria within a susceptible main population, is associated with treatment failure and often caused by tandem amplification of resistance genes. Here, we investigated how the

Vancomycin Heteroresistance in Methicillin-resistantStaphylococcus aureus, Taiwan

Emerging Infectious Diseases, 2004
To the Editor: In 1997, Hiramatsu and colleagues reported the first clinical isolate of methicillin-resistant Staphylococcus aureus (MRSA) showing reduced susceptibility to vancomycin (1). Soon thereafter, vancomycin-intermediate S. aureus (VISA) or heteroresistant VISA was reported to have disseminated in Japanese hospitals (2). In Taiwan, a survey of
