The microbial pan-genome

TL;DR: In this paper, the authors consider the exposure of food animals during the course of their lifespans to preventative, therapeutic or prophylactic treatment with antibiotic agents and find that therapeutic treatment of pathogenic organisms on farms increasing the likelihood of selective antibiotic pressure influencing the commensal flora of the intestines.

TL;DR: Results confirm the utility of implementing good agricultural practices to reduce Salmonella contamination in irrigation water and the packaging process and show that fresh produce farms that apply and enforce GAP could reduce the presence ofSalmonella in finished produce.

TL;DR: A phylogenomic analysis confirmed a clear separation between the Ovis and Equi biovars, but also showed what appears to be a clustering by host species within the Equi strains.

TL;DR: The annotation of the genome identified a total of 2377 protein-coding genes and revealed the presence of enzymes and pathways for formation of several flavor compounds and a comparative genomic analysis of strain JS and 29 other Propionibacterium strains of 10 different species contributed to the understanding of the genomic basis of P. freudenreichii.

TL;DR: Over 1.2 million previously unknown genes represented in these samples, including more than 782 new rhodopsin-like photoreceptors are identified, suggesting substantial oceanic microbial diversity.

TL;DR: The genomic sequence of six strains representing the five major disease-causing serotypes of Streptococcus agalactiae, the main cause of neonatal infection in humans, was generated and Mathematical extrapolation of the data suggests that the gene reservoir available for inclusion in the S. agalactic pan-genome is vast and that unique genes will continue to be identified even after sequencing hundreds of genomes.

TL;DR: Mobile elements within genomes have driven genome evolution in diverse ways and are becoming useful tools for learning more about genome evolution and gene function.

TL;DR: The current review presents the available genomics and biological data on prophages from bacterial pathogens in an evolutionary framework to demonstrate that the chromosomes from bacteria and their viruses (bacteriophages) are coevolving.
