Impact of carbapenem heteroresistance among clinical isolates of invasive Escherichia coli in Chongqing, southwestern China

open access: yesClinical Microbiology and Infection, 2015
Although heteroresistance is common in a wide range of microorganisms, carbapenem heteroresistance among invasive Escherichia coli infections has not been reported.

Theoretical considerations and empirical predictions of the pharmaco- and population dynamics of heteroresistance

open access: yesProceedings of the National Academy of Sciences of the United States of America
Antibiotics are considered one of the most important contributions to clinical medicine in the last century. Due to the use and overuse of these drugs, there have been increasing frequencies of infections with resistant pathogens. One form of resistance,

Emergence of Heteroresistance Mycobacterium Tuberculosis in Saudi Arabia

Infectious Disorders - Drug Targets, 2020
Purpose:Heteroresistant Mycobacterium tuberculosis (MTB) is defined as a group of drug-susceptible and resistant bacteria in a single clinical specimen from tuberculosis (TB) patients. Heteroresistance of MTB is considered a preliminary stage to full resistance.

Heteroresistance in Mycobacterium tuberculosis.

The international journal of tuberculosis and lung disease : the official journal of the International Union against Tuberculosis and Lung Disease, 2001
Drug resistance in Mycobacterium tuberculosis is often linked to specific mutations in a limited number of resistance genes. Detection of these mutations in a cultured isolate can predict the resistant phenotype. Genotypic analysis of the mycobacteria directly in a clinical specimen would result in considerable time saving for resistance prediction.To ...

Intrinsic clarithromycin heteroresistance in Mycobacterium avium

Journal of Infection and Chemotherapy
Mycobacterium avium is associated with pulmonary disease in otherwise healthy adults. Several clarithromycin-refractory cases have been reported, including some cases caused by clarithromycin-susceptible strains.To characterize the reason for the discrepancy between clinical response and antibiotic susceptibility results.We conducted population ...

Outcome of Heteroresistant Staphylococcus aureus Infections in Children

Journal of Infectious Diseases, 1987
Strains of Staphylococcus aureus may display heterogeneous resistance to penicillinase-resistant penicillins in vitro [1-3]. These strains contain methicillin-susceptible organisms that have the usual characteristics of nonheteroresistant S. aureus and methicillin-resistant organisms, which grow more slowly and may escape detection under ordinary ...

Heteroresistance: A Harbinger of Future Resistance

2018
During infection, bacterial populations often contain subpopulations that exhibit reduced antimicrobial susceptibility. The resulting population heterogeneity is called heteroresistance. Since a heteroresistant population can evolve into a resistant one, a heteroresistant infection is a risk factor for the development of complete resistance.
