Preharvest control strategies, to reduce or eliminate pathogenic bacteria in leafy vegetables that may be consumed raw, provide additional food safety protection and shelf life quality extension beyond what is possible achieve with postharvest sanitation alone. The aim of this study was characterize the efficacy effect contact time electrolyzed water (e-water), 1-bromo-3-chloro-5-dimethylhydant...

Reactive oxygen and nitrogen species can have either harmful or beneficial effects on biological systems depending on the dose administered and the species of organism exposed, suggesting that application of reactive species can possibly produce contradictory effects in disease control, pathogen inactivation and activation of host resistance. A novel technology known as atmospheric-pressure non...

Transfusion medicine is traditionally a strong/fundamental part of clinical practice, saving hundreds millions lives. However, blood-borne or transmitted infections are well-known and feared possibility, risk we relentlessly mitigate. Pathogens continuously rather quickly changing, so during the last decade, many, sometimes exotic, new pathogens diseases were recorded analyzed, some them proved...

The microalgal strain Chlorella sorokiniana isolated from a waste stabilization pond was used for tertiary treatment of municipal wastewater. Three light:dark (L:D) regimes 12:12, 16:8, and 24:0 were treating wastewater in microalga (A), + sludge (A S), (S) reactors. removal nutrients (N P) found to be the highest microalga-based reactor, with more than 80% biochemical oxygen demand (BOD) 1.2–5...

BACKGROUND: The transmission of pathogens via blood transfusion is still a major threat. Expert conferences established the need for a pro-active approach and concluded that the introduction of a pathogen inactivation/reduction technology requires a thorough safety profile, a comprehensive pre-clinical and clinical development and an ongoing hemovigilance program. MATERIAL AND METHODS: The INTE...

Escherichia coli O157:H7 (EHEC O157) is a serious pathogen causing haemorrhagic colitis. In this study, inactivation kinetics of inoculated EHEC O157 and response of EHEC O157 in apple wounds by different concentrations of C. oleophila was investigated. The results presented in this study indicated that EHEC O157 could survive and grow in wounded 'Fuji' apples and extensively proliferate. Water...

Achromobacter xylosoxidans is an emerging pathogen in cystic fibrosis patients. The multidrug resistance of these bacteria remains poorly understood. We have characterized in a clinical strain the first resistance-nodulation-cell division (RND)-type multidrug efflux pump in this species: AxyABM. The inactivation of the transporter component axyB gene led to decreased MICs of cephalosporins (exc...

Existing data and predictive models were used to define the input settings of a previously developed but modified quantitative risk assessment model (QRAM) for Salmonella and whole chickens. The QRAM was constructed in an Excel spreadsheet and was simulated using @Risk. The retail-to-table pathway was modeled as a series of unit operations and associated pathogen events that included initial co...

BACKGROUND Anthrax is a zoonotic disease recognized to affect herbivores since Biblical times and has the widest range of susceptible host species of any known pathogen. The ease with which the bacterium can be weaponized and its recent deliberate use as an agent of terror, have highlighted the importance of gaining a deeper understanding and effective countermeasures for this important pathoge...

Intact and decorticated single-celled Ascaris suum eggs were exposed to UV radiation from low-pressure, germicidal lamps at fluences (doses) ranging from 0 to 8,000 J/m2 for intact eggs and from 0 to 500 J/m2 for decorticated eggs. With a UV fluence of 500 J/m2, 0.44-+/-0.20-log inactivation (mean+/-95% confidence interval) (63.7%) of intact eggs was observed, while a fluence of 4,000 J/m2 resu...
