The microbial pan-genome
1.2K
TL;DR: A decade after the beginning of the genomic era, the question of how genomics can describe a bacterial species has not been fully addressed and the pan-genome, which is composed of a "core genome" containing genes present in all strains, and a "dispensable genome", might be orders of magnitude larger than any single genome.

Word Entropy-Based Approach to Detect Highly Variable Genetic Markers for Bacterial Genotyping.
Marketa Nykrynova,Vojtech Barton,Karel Sedlar,Matej Bezdicek,Martina Lengerová,Helena Skutkova +5 more
TL;DR: In this paper, a pipeline is proposed to detect highly variable genetic segments for genotyping a closely related bacterial population, based on a degree of disorder in analyzed sequences that can be represented by sequence entropy, which can be used to find out transmission routes and sources of highly virulent and multiresistant strains.
Análise in-silico de integrases no fitopatógeno Xylella fastidiosa: diversidade, sítios de integração e associação com bacteriófagos.

TL;DR: The data here presented support the role of integrases and their associated MGEs as key players in the process of evolution and diversity of the genomic organization between the four strains of Xf.
Mycobacterium tuberculosis complex lineage 5 exhibits high levels of within-lineage genomic diversity and differing gene content compared to the type strain H37Rv

Harris,Dorothy Yeboah-Manu,Sebastien Gagneux,Sebastien Gagneux,Leen Rigouts,Leen Rigouts,Dissou Affolabi,Bouke C. de Jong,Conor J. Meehan,Conor J. Meehan +18 more
TL;DR: The high within-lineage gene content variability suggests that the pan-genome of M. tuberculosis is at least several kilobases larger than previously thought, implying a concatenated or reference-free genome assembly (de novo) approach may be needed for particular questions.

TL;DR: A majority of the bacterial sequences corresponded to uncultivated species and novel microorganisms, and significant intersubject variability and differences between stool and mucosa community composition were discovered.

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.

Phages and the Evolution of Bacterial Pathogens: from Genomic Rearrangements to Lysogenic Conversion
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.
