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 ... -
Effects of growth phase and temperature onσbactivity within alisteria monocytogenespopulation: evidence for rsbv-independent activation ofσbat refrigeration temperatures
Utratna, Marta; Cosgrave, Eoin; Baustian, Claas; Ceredig, Rhodri H.; O’Byrne, Conor P. (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 ... -

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.
