Investigation of voriconazole heteroresistance in clinical isolates of Trichosporon asahii from a multicenter study in China

Microbiology Spectrum
Heteroresistance refers to the presence of subpopulations within seemingly homogeneous microbial cells that exhibit varying sensitivities to antifungal agents, potentially contributing to treatment failure.

Carbapenem Resistance in India: A Systematic Review of Epidemiology, Diagnostic Strategies, and Therapeutic Approaches

BioMed Research International, Volume 2026, Issue 1, 2026.
Background Carbapenem‐resistant gram‐negative infections pose a major public health challenge in India due to high antibiotic consumption, limited diagnostic access, and regional variation in resistance mechanisms. We systematically reviewed recent data to evaluate prevalence, diagnostics, and therapeutic strategies.

Clinical impact of bacterial heteroresistance

JAC-Antimicrobial Resistance
Abstract Bacterial heteroresistance is defined when a seemingly susceptible population of bacteria contains one or more resistant subpopulations. This behaviour has been seen in a variety of bacteria and with many different antibiotics.

Colistin Heteroresistance, Mechanisms, Diagnostic Methods, and Therapeutic Options: A Review

The heteroresistance phenotype refers to the presence of bacterial subpopulations with reduced antibiotic susceptibility compared with the main population. Mathematical modelling and computer simulations suggest that heteroresistance can lead to negative
