Although it is a human pathogen, Vibrio cholerae is a regular member of aquatic habitats, such as coastal regions and estuaries. Within these environments, V. cholerae often takes advantage of the abundance of zooplankton and their chitinous molts as a nut ...
Natural competence for transformation is a mode of horizontal gene transfer that is commonly used by bacteria to take up DNA from their environment. As part of this developmental program, so-called competence genes, which encode the components of a DNA-upt ...
Bacterial genomics is flourishing, as whole-genome sequencing has become affordable, readily available, and rapid. As a result, it has become clear how frequently horizontal gene transfer (HGT) occurs in bacteria. The potential implications are highly sign ...
Antibacterial action of silver nanoparticles (AgNP) on Gram-negative bacteria (planctonic cells and biofilms) is reported in this study. AgNP of 8.3 nm in diameter stabilized by hydrolyzed casein peptides strongly inhibited biofilms formation of Escherichi ...
Although Vibrio cholerae is a human pathogen its primary habitat are aquatic environments. In this environment, V. cholerae takes advantage of the abundance of zooplankton, whose chitinous exoskeletons provide a nutritious surface. Chitin also induces the ...
The human pathogen Vibrio cholerae is an aquatic bacterium associated with zooplankton and their chitinous exoskeletons. On chitinous surfaces, V. cholerae initiates a developmental programme, known as natural competence, to mediate transformation, which i ...
Several methods are available to manipulate bacterial chromosomes(1-3). Most of these protocols rely on the insertion of conditionally replicative plasmids (e.g. harboring pir-dependent or temperature-sensitive replicons(1,2)). These plasmids are integrate ...
Over the past years, molecular modeling and simulation techniques have had a major impact on experimental life sciences. They are capable of providing accurate insight into microscopic mechanisms, which are usually difficult to investigate experimentally. ...
The bacterial type VI secretion system (T6SS) is a large multicomponent, dynamic macromolecular machine that has an important role in the ecology of many Gram-negative bacteria. T6SS is responsible for translocation of a wide range of toxic effector molecu ...
There is a fundamental gap in our understanding of how horizontal gene transfer contributes to the enormous range of genetic variations that are observed among bacteria. The objective of our study was to better understand how the acquisition of genetic mat ...
