(American Society for Microbiology, 1997-03)One hundred reconstituted milk-based infant formulae (IMF) representative of 10 leading brands available in many European Economic Community countries were examined for Bacillus cereus and for the presence of diarrheal ... -
Light inactivation of food-related pathogenic bacteria using a pulsed power source.
(Wiley, 1998-06)The effects of high intensity light emissions, produced by a novel pulsed power energization technique (PPET), on the survival of bacterial populations of verocytotoxigenic Escherichia coli (serotype 0157:H7) and Listeria ... -
Cellular morphology of rough forms of Listeria monocytogenes isolated from clinical and food samples.
(The Society for Applied Microbiology, 2000)Transmission electron microscopy (TEM) studies revealed that rough cell-forms of L. monocytogenes (designated FR variants), isolated from clinical and food samples (and under conditions of sublethal heat stress), consist ... -
Virulent rough filaments of Listeria monocytogenes from clinical and food samples secreting wild-type levels of cell-Free p60 protein.
(American Society for Microbiology, 2000-07)Atypical rough cell filaments of Listeria monocytogenes (designated FR variants), isolated from clinical and food samples, form long filaments up to 96 microm in length and demonstrated wild-type levels of adherence, ... -
Putative virulence factor expression by clinical and food isolates of Bacillus spp.after growth in reconstituted infant milk formulae.
(American Society for Microbiology, 2001-09)Forty-seven strains representing 14 different Bacillus species isolated from clinical and food samples were grown in reconstituted infant milk formulae (IMF) and subsequently assessed for adherence to, invasion of, and ... -
Pulsed electric field inactivation of diarrhoeagenic Bacillus cereus through irreversible electroporation.
(The Society for Applied Microbiology, 2001-12)The physical effects of high‐intensity pulsed electric fields (PEF) on the inactivation of diarrhoeagenic Bacillus cereus cells suspended in 0·1% peptone water were examined by transmission electron microscopy (TEM). The ... -
Production of diarrheal enterotoxins and other potential virulence factors by veterinary isolates of Bacillus species associated with nongastrointestinal infections.
(American Society for Microbiology, 2003-04)With the exceptions of Bacillus cereus and Bacillus anthracis, Bacillus species are generally perceived to be inconsequential. However, the relevance of other Bacillus species as food poisoning organisms and etiological agents ... -
Use of a fluorescent viability stain to assess lethal and sublethal injury in food-borne bacteria exposed to high-intensity pulsed electric fields. (2004).
(The Society for Applied Microbiology, 2004-07)Aims: To apply scanning electron microscopy, image analysis and a fluorescent viability stain to assess lethal and sublethal in food-borne bacteria exposed to high-intensity pulsed electric fields (PEF). Methods and ... -
Pulsed-plasma gas-discharge inactivation of microbial pathogens in chilled poultry wash water.
(International Association for Food Protection, 2007-12)A pulsed-plasma gas-discharge (PPGD) system was developed for the novel decontamination of chilled poultry washwater. Treatment of poultry wash water in the plasma generation chamber for up to 24 s at 4C reduced Escherichia ... -
Evidence of lethal and sublethal injury in food‐borne bacterial pathogens exposed to high‐intensity pulsed‐plasma gas discharges.
(Wiley, 2008-01)Aims: To apply scanning electron microscopy, image analysis and a fluorescent viability stain to assess lethal and sublethal injury in food‐borne bacteria exposed to pulsed‐plasma gas discharges (PPGD). Methods and ... -
Studies on the inactivation of medically important Candida species on agar surfaces using pulsed light.
(2009-07)Development of a pulsed-light (PL) approach to inanimate surface decontamination is timely, as the incidence of yeast-related infections in healthcare remains unacceptably high. Critical electrical and biological factors ... -
Investigation of critical inter-related factors affecting the efficacy of pulsed light for inactivating clinically relevant bacterial pathogens
(Wiley, 2009-08)Aims: To investigate critical electrical and biological factors governing the efficacy of pulsed light (PL) for the in vitro inactivation of bacteria isolated from the clinical environment. Development of this alternative ... -
Studies on the susceptibility of different culture morphotypes of Listeria monocytogenes to uptake and survival in human polymorphonuclear leukocytes.
(Blackwell Publishing, 2009-09)This study demonstrated that atypical virulent filaments of Listeria monocytogenes (rough variant type II and designated FR for this study), isolated from clinical specimens or generated during exposure to pulsed-plasma ... -
Emergence of Bacillus Cereus as a dominant organism in Irish retailed powdered infant formulae (PIF) when reconstituted and stored under abuse conditions
(Wiley, 2010-05-25)One hundred powdered infant formulae (PIF), representative of the 10 leading brands available in Ireland, were subjected to a variety of preparation and storage conditions. All PIF analyzed immediately after reconstitution were ... -
Defining established and emerging microbial risks in the aquatic environment: current knowledge, implications, and outlooks.
(Hindawi, 2011)This timely review primarily addresses important but presently undefined microbial risks to public health and to the natural environment. It specifically focuses on current knowledge, future outlooks and offers some potential ... -
Irish staff nurses perceptions of clinical incident reporting
(Academic Journals, 2011-02)Clinical incident reporting identifies actual and potential risks to patient safety and then eliminates those risks through a system of procedural changes, policy enactment or changes in staff education. This constitutes ... -
Studies on the relationship between pulsed UV light irradiation and the simultaneous occurrence of molecular and cellular damage in clinically-relevant Candida albicans
(Elsevier, 2011-02)This constitutes the first study to report on the relationship between pulsed UV light (PL) irradiation and the simultaneous occurrence of molecular and cellular damage in clinical strains of Candida albicans. Microbial ... -
A review of the perceived barriers within the health belief model on PAP smear screening as a cervical cancer prevention measure.
(AESS, 2013)Aim: This study reviews the impact of perceived barriers on Pap cervical smear screening within the Health Belief Model (HBM) as an important prevention programme. Background: This research proposes to study perceived ... -
Efficacy of using harmless Bacillus endospores as novel surrogate organisms to indicate the inactivation performance of recalcitrant cryptosporidium parvus oocysts suspended in water using pulsed IV light
(American Society of Parasitologists, 2013-06)The need to use complex in vitro cell culture, expensive equipment and highly-trained technicians that are available only to specialist laboratories has significantly limited studies assessing the potential of pulsed UV ... -
A pulsed light system for the disinfection of flow through water in the presence of inorganic contaminants.
(IWA Publishing, 2014)The use of ultraviolet (UV) light for water disinfection has become increasingly popular due to on-going issues with drinking water and public health. Pulsed UV light has proved to be an effective form of inactivating a ...
