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.

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 to carbapenems in invasive Pseudomonas aeruginosa infections

International Journal of Antimicrobial Agents, 2018
Heteroresistance is common in a variety of microbes, however carbapenem heteroresistance among invasive Pseudomonas aeruginosa infections has not been thoroughly characterised to date. The objective of this study was to investigate the mechanisms, molecular epidemiology and risk factors for invasive carbapenem-heteroresistant P.

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.

Heteroresistance: a hidden cause behind antifungal prophylaxis failure

Trends in Microbiology
Invasive fungal infections in allogeneic hematopoietic stem cell transplant (allo-HSCT) recipients on antimicrobial prophylaxis is a major cause of infectious mortality, although its underlying pathophysiological mechanisms remain unclear. In a new report, Zhai and colleagues provide evidence that heteroresistance drives breakthrough Candida ...
