The development of novel therapies to control diseases caused by antibiotic-resistant
pathogens is one of the major challenges we are currently facing. Many important plant …

Biotic and abiotic surfaces in marine waters are rapidly colonized by microorganisms.
Surface colonization and subsequent biofilm formation and development provide numerous …

Many bacteria use a cell-cell communication system called quorum sensing to coordinate
population density-dependent changes in behavior. Quorum sensing involves production of …

The coordination of group behaviors in bacteria is accomplished via the cell-cell signaling
process called quorum sensing. Vibrios have historically been models for studying bacterial …

Many Proteobacteria use quorum sensing to regulate production of public goods, such as
antimicrobials and proteases, that are shared among members of a community. Public …

Bacterial cooperation can be disrupted by non-producers that can profit from public goods
without paying their production cost. A cheater can increase in frequency, exhausting the …

ABSTRACT The Gram-negative bacterium Vibrio cholerae is responsible for the severe
diarrheal pandemic disease cholera, representing a major global public health concern …

Bacterial quorum sensing enables bacteria to cooperate in a density-dependent manner via
the group-wide secretion and detection of specific autoinducer molecules. Many bacterial …

Bacteria live in complex polymicrobial communities and are constantly competing for
resources. The type VI secretion system (T6SS) is a widespread antagonistic mechanism …

As selection frequently favors noncooperating defectors in mixed populations with
cooperators, mechanisms that promote cooperation stability clearly exist. One potential …
