Sheahan M, Flores K, Coyne M, Garcia-Bayona L, Chatzidaki-Livanis M, Holst A, et al.
Science . 2024 Oct; 386(6720):414-420. PMID: 39446952
DNA transfer is ubiquitous in the human gut microbiota, especially among species of the order Bacteroidales. In silico analyses have revealed hundreds of mobile genetic elements shared between these species,...

Garcia-Bayona L, Said N, Coyne M, Flores K, Elmekki N, Sheahan M, et al.
bioRxiv . 2024 May; PMID: 38746121
Although horizontal gene transfer is pervasive in the intestinal microbiota, we understand only superficially the roles of most exchanged genes and how the mobile repertoire affects community dynamics. Similarly, little...

Fogarty E, Schechter M, Lolans K, Sheahan M, Veseli I, Moore R, et al.
Cell . 2024 Mar; 187(5):1206-1222.e16. PMID: 38428395
Plasmids are extrachromosomal genetic elements that often encode fitness-enhancing features. However, many bacteria carry "cryptic" plasmids that do not confer clear beneficial functions. We identified one such cryptic plasmid, pBI143,...
