Study on the heteroresistance of carbapenem-resistant Klebsiella pneumoniae to Tigecycline and Polymyxin B and antibacterial activity of combined drugs in vitro [PDF]
Background Antimicrobial resistance is a global concern. Tigecycline (TGC) and polymyxin B (PMB) constitute some of the last treatment options remaining for carbapenem-resistant Klebsiella pneumoniae (CRKP).

An investigation of gene dosage reveals that increased sensitivity to D-cycloserine divergently impacts the transience of heteroresistance in Escherichia coli [PDF]
Heteroresistance describes the phenomenon where seemingly isogenic bacterial populations contain subpopulations with elevated resistance compared to the susceptible majority that are often missed in routine susceptibility testing. The enhanced resistance

Deletions of recombination genes impair tandem amplification and reshape heteroresistance mechanisms in Escherichia coli [PDF]
Heteroresistance is a transient resistance phenotype characterized by the presence of small subpopulations of bacterial cells with elevated antibiotic resistance within a susceptible main population.

Characterization of Mycobacterium tuberculosis heteroresistance by genotyping
Background: Heteroresistance is the coexistence of susceptible and resistant strains in the same individual, considered the preliminary step for total resistance, and can stem from mixed infection or clonal heterogeneity.

Mixed infections and heteroresistance of Mycobacterium tuberculosis among multidrug-resistant tuberculosis in China: a genomic epidemiology study [PDF]
Mixed infection refers to the presence of multiple Mycobacterium tuberculosis strains within one host, while heteroresistance denotes the coexistence of drug-susceptible and drug-resistant strains or genotypes.

Investigation of Colistin Heteroresistance and Some Factors Affecting Heteroresistance in Carbapenem-Resistant A. baumannii Strains [PDF]
Introduction: Colistin can be used in patients infected with carbapenem-resistant Acinetobacter baumannii complex (CR-ABC), but recently resistance to colistin and heteroresistance have been reported.

Plasmid pHXY0908 confers ciprofloxacin heteroresistance to Salmonella enterica serovar typhimurium ATCC 14028 by regulating efflux pump gene expression [PDF]
Background Salmonella enterica Serovar Typhimurium (S. Typhimurium) is a major global foodborne pathogen. In our previous study, the S. Typhimurium ATCC 14028 strain harboring plasmid pHXY0908 survived at fourfold its ciprofloxacin MIC (MIC0908 = 0.125 ...
