Development and optimization of an egfp-based reporter for measuring the general stress response inlisteria monocytogenes
Utratna, Marta; Cosgrave, Eoin; Baustian, Claas; Ceredig, Rhodri; O’Byrne, Conor (Informa UK Limited, 2012-03-01)A characteristic of the food-borne pathogen Listeria monocytogenes is its tolerance to the harsh conditions found both in minimally processed foods and the human gastrointestinal tract. This trait is partly under the control ... -
The development of reporters to measure the general stress response in Listeria monocytogenes: population and single cell studies on the activation of SigmaB
Utratna, Marta (2012-09-28)The foodborne pathogen Listeria monocytogenes has a remarkable ability to persist and grow in harsh environments, including the human gastrointestinal tract. This attribute is regulated, at least partly, by the alternative ... -
Effects of growth phase and temperature on sigma(B) Activity within a Listeria monocytogenes population: evidence for RsbV-independent activation of sigma(B) at refrigeration temperatures
Utratna, Marta; Cosgrave, Eoin; Baustian, Claas; Ceredig, Rhodri H.; O’Byrne, Conor P. (Hindawi Publishing Corporation, 2014-03-05)The alternative sigma factor sigma(B) of Listeria monocytogenes is responsible for regulating the transcription of many of the genes necessary for adaptation to both food-related stresses and to conditions found within the ... -

(Hindawi Limited, 2014-01-01)The alternative sigma factor sigma(B) of Listeria monocytogenes is responsible for regulating the transcription of many of the genes necessary for adaptation to both food-related stresses and to conditions found within the ... -
Glycosylation-based serum biomarkers for cancer diagnostics and prognostics
Kirwan, Alan; Utratna, Marta; O’Dwyer, Michael E.; Joshi, Lokesh; Kilcoyne, Michelle (Hindawi Limited, 2015-01-01)Cancer is the second most common cause of death in developed countries with approximately 14 million newly diagnosed individuals and over 6 million cancer-related deaths in 2012. Many cancers are discovered at a more ... -
Rapid screening for specific glycosylation and pathogen interactions on a 78 species avian egg white glycoprotein microarray
Utratna, Marta; Annuk, Heidi; Gerlach, Jared Q.; Lee, Yuan C.; Kane, Marian; Kilcoyne, Michelle; Joshi, Lokesh (Nature Research, 2017-07-25)There is an urgent need for discovery of novel antimicrobials and carbohydrate-based anti-adhesive strategies are desirable as they may not promote resistance. Discovery of novel anti-adhesive molecules from natural product ... -
Thiamine plays a critical role in the acid tolerance of listeria monocytogenes
Madeo, Moira; O'Riordan, Niamh; Fuchs, Thilo M.; Utratna, Marta; Karatzas, Kimon Andreas G.; O'Byrne, Conor P. (Oxford University Press (OUP), 2011-11-14)Understanding the molecular basis of acid tolerance in the food-borne pathogen Listeria monocytogenes is important as this property contributes to survival in the food-chain and enhances survival within infected hosts. The ...
