implicated in the pathogenesis of human infection. Expression of some of these factors …

In gram-negative bacterial pathogens, such as Pseudomonas aeruginosa and Yersinia
pseudotuberculosis, cell-to-cell communication via the N-acylhomoserine lactone (AHL) …

For many years bacteria were considered primarily as autonomous unicellular organisms
with little capacity for collective behaviour. However, we now appreciate that bacterial cells …
