Summary Hepatitis E virus (HEV) is an emerging pathogen that can be transmitted through contaminated raw or undercooked meat derived from domestic pigs. HEV infections have been documented among pig herds, pig products and environmental samples raising concern about the spread of the virus. HEV genotypes 3 and 4 are considered zoonotic and have been linked to human cases. HEV was detected in 51...

Abstract Proteus mirabilis, a Gram-negative bacterium, is ubiquitous in the environment and is considered as the normal microflora in the human gastrointestinal tract. However, this bacterium is an opportunistic pathogen in humans, often causing urinary tract infections. Moreover, Proteus has been frequently isolated from food animals, including poultry. Whether this bacterium contributes to the...

AbstractBecause of the impossibility to consume food of animal origin, vegan consumers are looking for substitutes that could enrich their diet. Among many substitutes, fermented nut products are made from different nut types and obtained after soaking, grinding, and fermentation. Although other fermented vegetable products have been deeply investigated, there are few data about the fermentative...

Abstract Shellfish samples (n = 310) purchased from local supermarkets were analysed for the presence of hepatitis E virus (HEV) by nested RT-PCR and real-time qRT-PCR. Overall, 2.9% of samples tested positive for the presence of HEV. Phylogenetic analysis of HEV sequences revealed all as being genotype 3 HEV. This is the first report of the detection of HEV in commercially sold...

Swastik De, Katherine Kaus, Shada Sinclair, Brandon C. Case, Rich Olson Vibrio cholerae is an aquatic gram-negative microbe responsible for cholera, a pandemic disease causing life-threatening diarrheal outbreaks in populations with limited access to health care.

Reactive enamine stress caused by intracellular 2-aminoacrylate accumulation leads to pleiotropic growth defects in a variety of organisms. Members of the well-conserved RidA/YER057c/UK114 protein family prevent enamine stress by enhancing the breakdown of 2-aminoacrylate to pyruvate. In Salmonella enterica, the disruption of RidA allows 2-aminoacrylate to accumulate and inactivate a variety of...

Yersinia pestis, the causative agent of plague, evolved from the closely related pathogen Yersinia pseudotuberculosis. During its emergence, Y. pestis is believed to have acquired its unique pathogenic characteristics through numerous gene gains/losses, genomic rearrangements and single nucleotide polymorphism (SNP) changes. One such SNP creates a single amino acid variation in the DNA binding...

Vibrio parahaemolyticus is a marine bacterium that is globally associated as the leading cause of seafood-borne gastroenteritis. V. parahaemolyticus uses various toxins and two type 3 secretion systems (T3SS-1 and T3SS-2) to subvert host cells during infection. We previously determined that V. parahaemolyticus T3SS-1 activity is upregulated by increasing the expression level of the master...

The RidA protein (PF01042) from Salmonella enterica is a deaminase that quenches 2-aminoacrylate (2AA), and other reactive metabolites. In the absence of RidA, 2AA accumulates, damages cellular enzymes and compromises the metabolic network. In vitro, RidA homologs from all domains of life deaminate 2-aminoacrylate and RidA proteins from plants, bacteria, yeast, and humans complement the mutant...

Summary Food contamination by toxins (both mycotoxins and bacterial toxins) represents a great challenge for their implications on health. Toxins could be removed during production, but many times, they enter the gut and act on the host. To some extents, a benefit of probiotics could be the removal/neutralisation of harmful compounds in the gut with an indirect health effect on the host. Some...

ABSTRACT It takes several steps to bring food from the farm to the fork (dining table), and contamination with food-borne pathogens can occur at any point in the process. Campylobacter spp. and Salmonella spp. are the main microorganisms responsible for foodborne disease in the European Union. These two pathogens are able to persist throughout the food supply chain thanks to their ability to form...

Finlay Campbell, Camilla Strang, Neil Ferguson, Anne Cori, Thibaut Jombart Recent years have seen the development of numerous methodologies for reconstructing transmission trees in infectious disease outbreaks from densely sampled whole genome sequence data. However, a fundamental and as of yet poorly addressed limitation of such approaches is the requirement for genetic diversity to arise on...
