Exploiting social evolution in biofilms.
Bacteria are highly social organisms that communicate via signaling molecules, move collectively over surfaces and make biofilm communities. Nonetheless, our main line of defense against pathogenic bacteria consists of antibiotics-drugs that target individual-level traits of bacterial cells and thus, regrettably, select for resistance against their own action. A possible solution lies in target...
متن کاملSocial evolution in multispecies biofilms.
Microbial ecology is revealing the vast diversity of strains and species that coexist in many environments, ranging from free-living communities to the symbionts that compose the human microbiome. In parallel, there is growing evidence of the importance of cooperative phenotypes for the growth and behavior of microbial groups. Here we ask: How does the presence of multiple species affect the ev...
متن کاملAdaptive evolution in single species bacterial biofilms.
Little is known about the dynamics of cellular growth, death, and evolution within bacterial biofilms. Here we show evidence of evolution within single-species biofilms in real time. Escherichia coli harvested from 22-day-old biofilms express a competitive advantage over cells incubated in biofilms for shorter periods of time. This advantage is manifested as the ability of aged cells to outcomp...
متن کاملParallel Evolution in Streptococcus pneumoniae Biofilms
Streptococcus pneumoniae is a commensal human pathogen and the causative agent of various invasive and noninvasive diseases. Carriage of the pneumococcus in the nasopharynx is thought to be mediated by biofilm formation, an environment where isogenic populations frequently give rise to morphological colony variants, including small colony variant (SCV) phenotypes. We employed metabolic characte...
متن کاملSocial evolution of spatial patterns in bacterial biofilms: when conflict drives disorder.
A key feature of biological systems is the emergence of higher-order structures from interacting units, such as the development of tissues from individual cells and the elaborate divisions of labor in insect societies. Little is known, however, of how evolutionary competition among individuals affects biological organization. Here we explore this link in bacterial biofilms, concrete systems tha...
