Targeted bacterial immunity buffers phage diversity.
Bacteria have evolved diverse defense mechanisms that allow them to fight viral attacks. One such mechanism, the clustered, regularly interspaced, short palindromic repeat (CRISPR) system, is an adaptive immune system consisting of genetic loci that can take up genetic material from invasive elements (viruses and plasmids) and later use them to reject the returning invaders. It remains an open ...
متن کاملDynamics of adaptive immunity against phage in bacterial populations
The CRISPR (clustered regularly interspaced short palindromic repeats) mechanism allows bacteria to adaptively defend against phages by acquiring short genomic sequences (spacers) that target specific sequences in the viral genome. We propose a population dynamical model where immunity can be both acquired and lost. The model predicts regimes where bacterial and phage populations can co-exist, ...
متن کاملGlobal Phage Diversity
Ten new mycobacteriophage genomes presented by show that most phage diversity remains uncharacterized. Extrapolation suggests that less than 0.0002% of the global phage metagenome has been sampled. The new genomes also contain a number of potential virulence factors that may be important in pathogenesis.
متن کاملCRISPR-based herd immunity can limit phage epidemics in bacterial populations.
Herd immunity, a process in which resistant individuals limit the spread of a pathogen among susceptible hosts has been extensively studied in eukaryotes. Even though bacteria have evolved multiple immune systems against their phage pathogens, herd immunity in bacteria remains unexplored. Here we experimentally demonstrate that herd immunity arises during phage epidemics in structured and unstr...
متن کاملBacterial ‘immunity’ against bacteriophages
Vertebrate animals possess multiple anti-pathogen defenses. Individual mechanisms usually are differentiated into those that are immunologically adaptive vs. more "primitive" anti-pathogen phenomena described as innate responses. Here I frame defenses used by bacteria against bacteriophages as analogous to these animal immune functions. Included are numerous anti-phage defenses in addition to t...
