Comparative genomics combined with phenotypical analyses reveal novel acid stress response mechanisms in Listeria monocytogenes
(NUI Galway, 2023-06-13)Listeria monocytogenes is a pathogenic bacterium of significant concern for food safety. Its remarkable ability to withstand food-related stress and survive gastrointestinal passage is important for establishing ... -
Elucidation of the role of the glutamate decarboxylase system and the gamma-aminobutyric acid shunt pathway in the stress response of Listeria monocytogenes
(2014-07-22)The foodborne pathogen Listeria monocytogenes is the causative agent of listeriosis in humans and other animals. This disease can have a fatality rate of up to 30% in infected patients and leads to spontaneous abortion in ... -
Investigation into the prevalence and persistence of Listeria monocytogenes in Irish seafood: Possible roles for σB in environmental persistence
(2017-03-31)L. monocytogenes is a robust bacterial pathogen capable of surviving in a wide range of environments including food processing facilities. This pathogen is of concern for the food processing industry particularly producers ... -
Molecular investigation into the roles of Sigma B and the Stressosome in the response of Listeria monocytogenes to environmental stress
(NUI Galway, 2019-07-15)The alternative sigma factor, SigB, has been studied extensively in Listeria monocytogenes, Bacillus subtilis and Staphylococcus aureus, and is known to regulate the general stress response in these bacteria. The activation ... -
Overlaps in the regulatory networks of Listeria monocytogenes in response to environmental cues
(NUI Galway, 2019-09-30)The facultative intracellular pathogen Listeria monocytogenes is a highly adaptable organism widely distributed in the environment. The ingestion of food contaminated with L. monocytogenes by at-risk individuals can ... -
Regulation and evolution of the σB stress sensing pathway in Listeria monocytogenes: impact on stress tolerance, fitness and virulence
(NUI Galway, 2022-06-15)The Gram-positive bacterium Listeria monocytogenes is the aetiological agent of listeriosis, a high death rate infection in susceptible groups, caused by the ingestion of contaminated food. L. monocytogenes is a highly ...
