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 ...
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 ...
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 ...
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 ...
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 ...
Maltodextrin stimulates growth of Bacillus cereus and synthesis of diarrheal enterotoxin in infant milk formulae.
(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 ...
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 ...
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 ...
