The high prevalence of antibiotic heteroresistance in pathogenic bacteria is mainly caused by gene amplification

, 2019
When choosing antibiotics to treat bacterial infections, it is assumed that the susceptibility of the target bacteria to an antibiotic is reflected by laboratory estimates of the minimum inhibitory concentration (MIC) needed to prevent bacterial growth ...

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

Widespread heteroresistance to antibiotics in Lactobacillus species

Abstract Lactobacilli are prevalent members of the intestinal and reproductive tract microbiota of humans and other species. They are commonly used in probiotics and various food products due to their beneficial effects on human health.

Ceftazidime/avibactam Improves the Antibacterial Efficacy of Polymyxin B Against Polymyxin B Heteroresistant KPC-2-Producing Klebsiella pneumoniae and Hinders Emergence of Resistant Subpopulation in vitro

Frontiers in Microbiology, 2019
Due to the increasing multidrug resistance and limited antibiotics, polymyxin B revived as the last resort for the treatment of carbapenemase-producing Klebsiella pneumoniae (CRKP).

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.

Fluoroquinolones and rifampin combination in the backdrop of heteroresistant tuberculosis

Antimicrobial Agents and Chemotherapy
ABSTRACT The impact of heteroresistance on tuberculosis (TB) treatment outcomes is unclear, as is the role of different rifampin and isoniazid exposures on developing resistance mutations. Hollow fiber system model of TB (HFS-TB) units were inoculated with drug-susceptible Mycobacterium ...

Genetic Evaluation of Heteroresistance among Carbapenem-Susceptible Clinical Isolates of Enterobacterales

Canadian Journal of Infectious Diseases and Medical Microbiology
Carbapenems currently serve as the last line of defense when treating serious infections caused by multidrug-resistant Enterobacterales species; however, heteroresistance of these species is thought to cause failure in the treatment with these broad ...
