Deciphering contaminants and toxins in fermented food for enhanced human health safeguarding

Comprehensive Reviews in Food Science and Food Safety, Volume 23, Issue 5, September 2024.
Abstract Fermented foods have been a component of the human diet since ancient times, including live bacteria employed to restore gut health, contributing to the frontline of functional food progression. Human concern about the harmful consequences of possible contaminants has increased significantly as their toxicity, carcinogenicity, and ...

Shiga-toxigenic Escherichia coli O157 and non-Shiga-toxigenic E. coli O157 respond differently to culture and isolation from naturally contaminated bovine faeces [PDF]

Journal of Applied Microbiology, 2007
To quantify the effect of enrichment, immunomagnetic separation (IMS), and selective plating procedures on isolation of Shiga-toxigenic Escherichia coli O157 (STEC O157) and non-Shiga-toxigenic Escherichia coli O157 (non-STEC O157) from naturally contaminated bovine faeces.Two broth enrichment times, two IMS strategies, and two selective plating media ...

Diffusion properties of single FoF1-ATP synthases in a living bacterium unraveled by localization microscopy [PDF]

, 2012
FoF1-ATP synthases in Escherichia coli (E. coli) bacteria are membrane-bound enzymes which use an internal proton-driven rotary double motor to catalyze the synthesis of adenosine triphosphate (ATP). According to the 'chemiosmotic hypothesis', a series of proton pumps generate the necessary pH difference plus an electric potential across the bacterial ...

Pathogenic Potential to Humans of Bovine Escherichia coli O26, Scotland [PDF]

, 2012
Escherichia coli O26 and O157 have similar overall prevalences in cattle in Scotland, but in humans, Shiga toxin–producing E. coli O26 infections are fewer and clinically less severe than E. coli O157 infections.

Public health aspects of Vibrio spp. related to the consumption of seafood in the EU

EFSA Journal, Volume 22, Issue 7, July 2024.
Abstract Vibrio parahaemolyticus, Vibrio vulnificus and non‐O1/non‐O139 Vibrio cholerae are the Vibrio spp. of highest relevance for public health in the EU through seafood consumption. Infection with V. parahaemolyticus is associated with the haemolysins thermostable direct haemolysin (TDH) and TDH‐related haemolysin (TRH) and mainly leads to acute ...

Enteric pathogen survival varies substantially in irrigation water from Belgian lettuce producers [PDF]

, 2014
It is accepted that irrigation water is a potential carrier of enteric pathogens, such as Salmonella and E. coli O157:H7 and, therefore, a source for contamination of fresh produce.

Contribution of MALDI‐TOF mass spectrometry and machine learning including deep learning techniques for the detection of virulence factors of Clostridioides difficile strains

Microbial Biotechnology, Volume 17, Issue 6, June 2024.
This study assessed the use of MALDI‐TOF Mass Spectrometry combined with Machine Learning including Deep Learning techniques to identify toxigenic and hypervirulent strains of Clostridioides difficile. The method demonstrated high accuracy, particularly in excluding non‐toxigenic strains with a negative predictive value of 0.95 and consistently high ...

Pressure and temperature dependence of growth and morphology of Escherichia coli: Experiments and Stochastic Model [PDF]

, 2012
We have investigated the growth of Escherichia coli E.coli, a mesophilic bacterium, as a function of pressure $P$ and temperature $T$. E.coli can grow and divide in a wide range of pressure (1-400atm) and temperature ($23-40^{\circ}$C). For $T>30^{\circ}$ C, the division time of E.coli increases exponentially with pressure and exhibit a departure from ...

Genotyping and antimicrobial resistance patterns of Escherichia coli O157 originating from cattle farms [PDF]

, 2011
During a Escherichia coli O157 prevalence study on cattle farms, 324 E. coli O157 isolates were collected from 68 out of 180 cattle farms. All isolates harbored the eaeA gene and the enterohemolysin (ehxA) gene. The majority of the strains only contained
