Rapid evolution of distinct Helicobacter pylori subpopulations in the Americas

Kaisa Thorell, Koji Yahara, Elvire Berthenet, Daniel J Lawson, Ikuko Kato, Alfonso Tenorio Mendez, Federico Canzian, Maria Mercedes Bravo, Rumiko Suzuki, Yoshio Yamaoka, Javier Torres, Samuel K Sheppard, Daniel Falush

This study analyzes H. pylori genome sequences from the Americas to show rapid evolution and genetic exchange leading to distinct subpopulations linked to human demographics and transmission ecology.

Genetic and chemical differentiation of Campylobacter coli and Campylobacter jejuni lipooligosaccharide pathways

Alejandra Culebro, Joana Revez, Ben Pascoe, Yasmin Friedmann, Matthew D Hitchings, Jacek Stupak, Samuel K Sheppard, Jianjun Li, Mirko Rossi

The paper investigates genetic and chemical diversity of lipooligosaccharides (LOS) in C. coli, identifying species-specific features distinguishing it from C. jejuni.

Genomic plasticity and rapid host switching promote the evolution of generalism in the zoonotic pathogen Campylobacter

Dan J Woodcock, Peter Krusche, Norval JC Strachan, Ken J Forbes, Frederick M Cohan, Guillaume Meric, Samuel K Sheppard

This study models how horizontal gene transfer and recombination influence the evolution of host generalism in Campylobacter, showing that low recombination increases standing variation for adaptive responses.

The impact of host metapopulation structure on the population genetics of colonizing bacteria

Elina Numminen, Michael U Gutmann, Mikhail Shubin, Pekka Marttinen, Guillaume Meric, Willem van Schaik, Teresa Coque, Fernando Baquero, Rob Willems, Samuel K Sheppard, Edward J Feil, William P Hanage, Jukka Corander

The paper models how host metapopulation structure affects bacterial genetic diversity, showing migration can increase or decrease strain relatedness depending on microepidemic rates.
