Mutants with heteroresistance to amphotericin B and fluconazole in Candida [PDF]

Brazilian Journal of Microbiology, 2009
Several studies have reported the occurrence of infections caused by Candida yeasts as well as the increasing prevalence of non albicans species. The aim of the present work is focused on the obtaining of heteroresistance to amphotericin B and fluconazole in Candida species using two distinct methodologies: selection and induction.

Phenotypic Detection of Hemin-Inducible Trimethoprim-Sulfamethoxazole Heteroresistance in Staphylococcus aureus

Microbiology Spectrum, 2021
Trimethoprim-sulfamethoxazole (SXT) is a valuable second-line antimicrobial agent to treat methicillin-resistant Staphylococcus aureus infections. Discrepancies between various antibiotic susceptibility testing (AST) methods for SXT susceptibility in S ...

Antibacterial Effect of the In Vitro Interaction Between Clotrimazole and Chlorhexidine Against Staphylococcus pseudintermedius With Known Resistance Patterns Isolated From Canine Pyoderma

Veterinary Medicine and Science, Volume 12, Issue 5, September 2026.
The 2:1 chlorhexidine–clotrimazole combination demonstrated enhanced antibacterial activity against canine Staphylococcus pseudintermedius isolates, including resistant strains. Reduced MIC values, predominantly additive interactions and absence of antagonism support its use as a promising topical strategy for canine pyoderma management.

Mechanisms of heteroresistance in methicillin-resistant Staphylococcus aureus [PDF]

Antimicrobial Agents and Chemotherapy, 1994
Characteristic for methicillin-resistant (Mcr) staphylococci is the heterogeneous expression of the intrinsic methicillin resistance. The majority of the cells express resistance to low concentrations of methicillin, and a minority of the cells express resistance to much higher concentrations.

Genotypes, Fluconazole Tolerance and Virulence Phenotypes of Candida albicans Bloodstream Isolates: A Multilocus Sequence Typing‐Based Analysis

Mycoses, Volume 69, Issue 9, September 2026.
ABSTRACT Background Fluconazole tolerance is an emerging phenotype in Candida albicans bloodstream infections, but its relationship to multilocus sequence typing (MLST) lineages and virulence traits is unclear. Objectives To investigate the relationships among MLST genotypes, fluconazole tolerance, and virulence phenotypes in C.

Prevalence, Antimicrobial Resistance Profile, and Multidrug Resistance of Methicillin‐Resistant Staphylococcus aureus (MDR‐MRSA) in Clinical Isolates From Indonesian Healthcare Facility: A Cross‐Sectional Study

Health Science Reports, Volume 9, Issue 8, August 2026.
ABSTRACT Background and Aims Methicillin‐resistant Staphylococcus aureus (MRSA) is a significant pathogen associated with hospital‐acquired infections, with its global prevalence, including in Indonesia, steadily increasing. However, comprehensive data on MRSA prevalence and antimicrobial susceptibility within Indonesian hospital settings remain ...

A low affinity penicillin-binding protein 2x is required for heteroresistance in Streptococcus pneumoniae [PDF]

, 2014
Heteroresistance to penicillin in Streptococcus pneumoniae is the ability of subpopulations to grow at a higher antibiotic concentration than expected from the minimal inhibitory concentration (MIC).
