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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
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, ...
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 ...
