Absence of curli in soil-persistent escherichia coli is mediated by a c-di-gmp signaling defect and suggests evidence of biofilm-independent niche specialization
Somorin, Yinka M.; Vollmerhausen, Tara; Waters, Nicholas; Pritchard, Leighton; Abram, Florence; Brennan, Fiona; O’Byrne, Conor (Frontiers Media SA, 2018-06-22)Escherichia coli is commonly viewed as a gastrointestinal commensal or pathogen although an increasing body of evidence suggests that it can persist in non-host environments as well. Curli are a major component of biofilm ... -

The genomics of soil-persistant E. coli
Waters, Nicholas (NUI Galway, 2020-11-19)Escherichia coli’s remarkable ability to thrive both in the gut and in soil confounds many assumptions made about the bacterium’s ecological niche specialisation, and a growing body of research has challenged the long-held ... -
Identification of Components of the Sigma B Regulon in Listeria monocytogenes That Contribute to Acid and Salt Tolerance
Boyd, Aoife; Abram, Florence; Karatzas, Kimon-andreas; Matlawska-Wasowska, Ksenia; Connolly, David; O'Byrne, Conor P.; Starr, Emily (American Society for Microbiology, 2008-09)Sigma B is an alternative sigma factor that controls the transcriptional response to stress in Listeria monocytogenes and is also known to play a role in the virulence of this human pathogen. In the present study we ... -
