Bacteria lie, cheat and steal

The growth and success of bacterial populations depends upon the production of extracellular factors that are secreted to perform many functions such as nutrient acquisition, protection from the environment and the creation of enemy-free space. These factors provide a benefit … Continue reading

Microbial Spy Games

Gathering and sharing of information is extremely important in human society. Especially in times of war, the difference between victory and defeat can depend on the ability to obtain, encrypt, and share information, and sophisticated systems have been developed for … Continue reading

Can Bacteria Evolve Resistance to Quorum Sensing Disruption?

Traditional treatment of bacterial infections relies heavily on the use of antibacterial compounds that either kill bacteria (bactericidal) or inhibit their growth (bacteriostatic). Typically, the targets for the main conventional antibiotics are essential cellular processes such as bacterial cell wall … Continue reading

Interspecies chemical communication in bacterial development

Our view of bacteria, from the earliest observations through the heyday of antibiotic discovery, has shifted dramatically. We recognize communities of bacteria as integral and functionally important components of diverse habitats, ranging from soil collectives to the human microbiome. To … Continue reading

How smart are bacteria?

A recent article in New Scientist entitled Why microbes are smarter than you thought looks at six behaviours that seem remarkably intelligent for single celled organisms. Single-celled organisms don’t have nervous systems, let alone brains, but they could be viewed … Continue reading
