Its high genome plasticity and recombination rate allow it to adapt to multiple hosts and lead to the rapid emergence of lineages, some of which can be antibiotic resistant. Our aim in this study was to examine the population structure of\n                    <jats:italic>Campylobacter<\/jats:italic>\n                    in California and assess its differentiation between animal hosts and humans.

By comparing groups of isolates, we detected significant levels of differentiation between the human and animal Californian isolates.

By identifying the genomic regions that were contributing to population differentiation amongst the host groups, we were able to identify protein variants potentially responsible for host adaptation and propensity to cause infection in humans.\n                  <\/jats:p>","DOI":"10.1099\/mgen.0.001589","type":"journal-article","created":{"date-parts":[[2025,12,8]],"date-time":"2025-12-08T18:16:56Z","timestamp":1765217816000},"source":"Crossref","is-referenced-by-count":0,"title":["Identification of genetic determinants that drive population differentiation and host adaptation in Campylobacter jejuni in California"],"prefix":"10.1099","volume":"11","author":[{"given":"Evangelos A.","family":"Dimopoulos","sequence":"first","affiliation":[{"name":"Department of Biology, Ineos Oxford Institute for Antimicrobial Research, University of Oxford, Oxford, UK"},{"name":"Department of Veterinary Medicine, University of Cambridge, Cambridge, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Caitlin E.
