Acquisition of Daptomycin Resistance by Enterococcus faecium Confers Collateral Sensitivity to Glycopeptides

Frontiers in Microbiology, 2022
Daptomycin is a last-line antibiotic used in the treatment of multidrug-resistant Enterococcus faecium infections. Alarmingly, daptomycin-resistant E. faecium isolates have emerged.

Fitness Cost of Antiretroviral Drug Resistance Mutations on the pol Gene during Analytical Antiretroviral Treatment Interruption among Individuals Experiencing Virological Failure

Pathogens, 2021
HIV cure studies require patients to enter an analytical treatment interruption (ATI). Here, we describe previously unanalyzed data that sheds light on ATI dynamics in PLHIV (People Living with HIV).

A Novel Small RNA on the Pseudomonas putida KT2440 Chromosome Is Involved in the Fitness Cost Imposed by IncP-1 Plasmid RP4

Frontiers in Microbiology, 2020
Plasmids can provide advantageous traits to host bacteria, although they may impose a fitness cost. Chromosome-encoded factors are important for regulating the expression of genes on plasmids, and host chromosomes may differ in terms of their ...

CRISPR-enabled investigation of fitness costs associated with the E198A mutation in β-tubulin of Colletotrichum siamense

Frontiers in Plant Science, 2023
IntroductionUnderstanding fitness costs associated with fungicide resistance is critical to improve resistance management strategies. E198A in b-tubulin confers resistance to the fungicide thiophanate-methyl and has been widely reported in several plant ...

A Small Multihost Plasmid Carrying erm(T) Identified in Enterococcus faecalis

Frontiers in Veterinary Science, 2022
The aim of this study was to determine the mobile genetic elements involved in the horizontal transfer of erm(T) in Enterococcus faecalis, and its transmission ability in heterologous hosts. A total of 159 erythromycin-resistant enterococci isolates were
