Proteus mirabilis is well known in clinical laboratories and microbiology survey courses as
the species that swarms across agar surfaces, overtaking any other species present in the …

How bacteria regulate, assemble and rotate flagella to swim in liquid media is reasonably
well understood. Much less is known about how some bacteria use flagella to move over the …

Acute infections caused by pathogenic bacteria have been studied extensively for well over
100 years. These infections killed millions of people in previous centuries, but they have …

Most of the research on bacterial pathogenesis has focused on acute infections, but much
less is known about the pathogenesis of infections caused by bacteria that grow as …

▪ Abstract Quorum sensing is the regulation of gene expression in response to fluctuations in
cell-population density. Quorum sensing bacteria produce and release chemical signal …

Serratia species, in particular Serratia marcescens, are significant human pathogens. S.
marcescens has a long and interesting taxonomic, medical experimentation, military …

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 …

Numerous species of bacteria employ a mechanism of intercellular communication known
as quorum sensing. This signaling process allows the cells comprising a bacterial colony to …

Quorum sensing relies upon the interaction of a diffusible signal molecule with a
transcriptional activator protein to couple gene expression with cell population density. In …

Quorum sensing (QS) is a communication process between cells, in which bacteria secrete
and sense the specific chemicals, and regulate gene expression in response to population …
