Genomic tailoring of autogenous poultry vaccines to reduce Campylobacter from farm to fork

J. K. Calland, M. E. Pesonen, J. Mehat, B. Pascoe, D. J. Haydon, J. Lourenco, E. Mourkas, M. D. Hitchings, R. M. LaRagione, P. Hammond, T. S. Wallis, J. Corander, S. K. Sheppard

This paper develops a genomic autogenous vaccine for poultry to reduce Campylobacter, showing reduced extra-intestinal survival genes and meat surface survival in vaccinated flocks.

Local accessory gene sharing drives lineage-specific acquisition of antimicrobial resistance in Egyptian Campylobacter spp.

S. F. Mouftah, B. Pascoe, J. K. Calland, E. Mourkas, N. Tonkin, C. Lefevre, D. Deuker, S. Smith, H. Wickenden, M. D. Hitchings, S. K. Sheppard, M. Elhadidy

This study analyzes Campylobacter isolates from Egypt to show increased local accessory genome sharing in specific lineages, contributing to higher antimicrobial resistance in C. coli.

Host ecology regulates interspecies recombination in bacteria of the genus Campylobacter

E. Mourkas, K. Yahara, S. C. Bayliss, J. K. Calland, H. Johansson, L. Mageiros, Z. Y. Munoz-Ramirez, G. Futcher, G. Meric, M. D. Hitchings, S. Sandoval-Motta, J. Torres, K. A. Jolley, M. C. Maiden, P. Ellstrom, , S. K. Sheppard

The paper quantifies horizontal gene transfer (HGT) between Campylobacter species with different host ecologies, showing cohabitation in the same host increases HGT by 6-fold.

Non-serotype 2 isolates from healthy pigs are a potential zoonotic reservoir of Streptococcus suis genetic diversity and antimicrobial resistance

N. Kittiwan, J. K. Calland, E. Mourkas, M. D. Hitchings, S. Murray, P. Tadee, P. Tadee, K. Duangsonk, S. K. Sheppard, G. Meric, P. Patchanee, B. Pascoe

The paper identifies non-serotype 2 Streptococcus suis isolates from healthy pigs as a reservoir of genetic diversity and antimicrobial resistance, which may contribute to zoonotic transmission and treatment failure.

A two-hit epistasis model prevents core genome disharmony in recombining bacteria

A. J. Taylor, K. Yahara, B. Pascoe, L. Mageiros, E. Mourkas, J. K. Calland, S. Puranen, M. D. Hitchings, K. A. Jolley, C. M. Kobras, S. C. Bayliss, N. J. Williams, A. H. van Vliet, J. Parkhill, M. C. Maiden, , S. K. Sheppard

The paper shows that recombination in bacteria can overcome genomic disharmony through a two-hit epistasis model, allowing beneficial gene combinations to be reinstated in new genetic backgrounds.
