Evolution and ecology of antibiotic resistance genes [PDF]

open access: yesFEMS Microbiology Letters, 2007
A new perspective on the topic of antibiotic resistance is beginning to emerge based on a broader evolutionary and ecological understanding rather than from the traditional boundaries of clinical research of antibiotic-resistant bacterial pathogens. Phylogenetic insights into the evolution and diversity of several antibiotic resistance genes suggest ...

Synthetic microbial ecosystems : an exciting tool to understand and apply microbial communities [PDF]

open access: yes, 2013
Many microbial ecologists have described the composition of microbial communities in a plenitude of environments, which has greatly improved our basic understanding of microorganisms and ecosystems.

Ecological feedbacks and the evolution of resistance [PDF]

open access: yesJournal of Animal Ecology, 2009
Summary 1.  The idea that parasites can affect host diversity is pervasive, and the possibility that parasites can increase host diversity is of particular interest. In this review, we focus on diversity in the resistance of hosts to their parasites, and on the different ways in which parasites can increase or decrease this ...

Conserved and specific features of Streptococcus pyogenes and Streptococcus agalactiae transcriptional landscapes

open access: yesBMC Genomics, 2019
Background The human pathogen Streptococcus pyogenes, or group A Streptococcus, is responsible for mild infections to life-threatening diseases. To facilitate the characterization of regulatory networks involved in the adaptation of this pathogen to its ...

The ecology and evolution of tetracycline resistance [PDF]

open access: yesTrends in Ecology & Evolution, 1992
The use of tetracycline over the past few decades has been accompanied by a drastic increase in the frequency of tetracycline resistance in a wide range of bacterial species and genera. A diversity of resistance determinants is found in the microbial world, coding for markedly different mechanisms of resistance.

Evolution of VIM-1-Producing Klebsiella pneumoniae Isolates from a Hospital Outbreak Reveals the Genetic Bases of the Loss of the Urease-Positive Identification Character

open access: yesmSystems, 2021
Evolution of multidrug-resistant bacterial pathogens occurs at multiple scales, in the patient, locally in the hospital, or more globally. Some mutations or gene acquisitions, for instance in response to antibiotic treatment, may be restricted to a ...

Complex genome evolution in Anopheles coluzzii associated with increased insecticide usage in Mali. [PDF]

open access: yes, 2015
In certain cases, a species may have access to important genetic variation present in a related species via adaptive introgression. These novel alleles may interact with their new genetic background, resulting in unexpected phenotypes.

Hawaiian Picture‐Winged Drosophila Exhibit Adaptive Population Divergence along a Narrow Climatic Gradient on Hawaii Island [PDF]

open access: yes, 2019
1. Anthropogenic influences on global processes and climatic conditions are increasingly affecting ecosystems throughout the world. 2. Hawaii Island’s native ecosystems are well studied and local long‐term climatic trends well documented, making these ...
