Pervasive bacterial and prophage hybridization during chronic gut inflammation

Marta Lourenço, Elsa Seixas, Patrícia Mexia…·Isabel Gordo

The paper shows that chronic gut inflammation drives bacterial and prophage hybridization in E. coli, leading to new genetic lineages associated with inflammatory bowel disease.
