Fitness cost bacteria
WebTo elucidate the fitness cost of these plasmids on the bacterial host, we collected blaNDM-negative strains from different sources and tested their ability to acquire the blaNDM-5-harboring p3R-IncX3 plasmid. We then measured changes in antimicrobial susceptibility, growth kinetics, and biofilm formation following plasmid acquisition. WebApr 6, 2024 · We characterized the diversification dynamics for various systems (bacteria and yeast) and for different phenotypes (utilization of alternative carbon sources, general stress response and more complex development patterns). Interestingly, our results suggest that the diversification dynamics and the fitness cost associated with cell switching ...

WebMay 11, 2024 · The fitness cost (or benefit) of bearing plasmids was modelled as a random variable that modifies the wild-type (plasmid-free) growth rate by a factor σ, such that if σ … WebDec 3, 2024 · Acquisition of resistance plasmids or chromosomal mutations are expected to cost the fitness of bacterial cell while chromosomal mutations carry a larger fitness cost compared to the acquisition of antibiotic resistance via a plasmid as explained by the high frequency of plasmid acquired evolution of antibiotic resistance (Silva et al ...
WebThe fitness cost of antibiotic resistance is a crucial factor to determine the evolutionary and transmission success of resistant bacteria. Exploring the fitness cost and compensation mechanism of antibiotic resistance genes (ARGs) in bacteria may effectively reduce the transmission of drug-resistant genes in the environment. WebJan 9, 2012 · The proposed mathematical model was found to be reasonable in characterizing bacterial growth and predicting the fitness cost of resistance. This simple …
