How Well Do Routine Molecular Diagnostics Detect Rifampin Heteroresistance in Mycobacterium tuberculosis ?

, 2019
International audienceRifampin heteroresistance—where rifampin-resistant and -susceptible tuberculosis (TB) bacilli coexist—may result in failed standard TB treatment and potential spread of rifampin-resistant strains.

Heterogeneous subpopulations in Escherichia coli strains acquire adaptive resistance to imipenem treatment through rapid transcriptional regulation

Frontiers in Cellular and Infection Microbiology
IntroductionHeteroresistance is a well-known phenomenon contributing to treatment failure in bacterial infections. Previous research has traditionally linked it to genetic mechanisms, emphasizing fixed subpopulations with specific resistance mutations ...

Investigation of colistin heteroresistance and the colistin resistance genes mcr-1 to mcr-5 in Escherichia coli and Klebsiella pneumoniae isolates in a tertiary hospital in Turkey

Journal of Infection in Developing Countries
Introduction: Heteroresistance is not detected by traditional antimicrobial susceptibility testing methods and may lead to treatment failures. Investigating the presence of plasmid-mediated colistin resistance genes is important because of the ...

Spread of an MRSA clone with heteroresistance to oxacillin in the Netherlands

Eurosurveillance, 2002
Since 2001, an increase in the number of MRSA strains with heteroresistance to oxacillin has been observed in the Netherlands. These strains can spread unnoticed, as their phenotypic heterogenous resistance to beta-lactams affects the results of susceptibility testing. Therefore, further testing using PBP2a latex agglutination or PCR are recommended.

Colistin heteroresistance in Klebsiella pneumonia and its association with slow-growing subpopulations within biofilms [PDF]

, 2016
The emergence of multidrug-resistant strains of Klebsiella pneumoniae is a growing clinical concern that is leading to the re-introduction of the old and toxic colistin as a salvage therapy.

Imipenem heteroresistance: evaluation of Klebsiella pneumoniae carbapenemase-producing and non-producing K. pneumoniae and E. coli

, 2013
The misdetection of Klebsiella pneumoniae carbapenemase (KPC) may lead to treatment failure and favour the spread of this resistance mechanism. Heteroresistance is an antimicrobial resistance in a subset of an isolate considered to be susceptible by ...
