Impact of Nutrient Restriction on the Structure of Listeria monocytogenes Biofilm Grown in a Microfluidic System
(2017-05-17)
Biofilm formation by the pathogen Listeria monocytogenes is a major concern in
food industries. The aim of this work was to elucidate the effect of nutrient
limitation on both biofilm architecture and on the ...
The fecal presence of enterotoxin and F4 genes as an indicator of efficacy of treatment with colistin sulfate in pigs
(2017)
Background :
Enterotoxigenic Escherichia coli (ETEC) strains producing multiple enterotoxins are important causes of post-weaning diarrhea (PWD) in pigs. The aim of the present study was to investigate the fecal presence ...
Antinociceptive activity of vanilloids in caenorhabditis elegans is mediated by the desensitization of the TRPV channel OCR-2 and specific signal transduction pathways
(Springer, 2023-02-03)
Vanilloids, including capsaicin and eugenol, are ligands of transient receptor potential channel vanilloid subfamily member 1 (TRPV1). Prolonged treatment with vanilloids triggered the desensitization of TRPV1, leading to ...
Extended-spectrum β-lactamase, carbapenemase, and the mcr-1 gene: Is there a historical link?
(2017-03-30)
The plasmid mediated mcr-1 gene encoding for Enterobacteriaceae colistin resistance has been recently identified across five continents. The objective of the present study was to trace historical events concerning the ...
Dynamics of viral distribution in a defined swine production network using enteric viruses as molecular markers
(2017-02)
Modern swine production systems represent complex and dynamic networks
involving numerous stakeholders. For instance, livestock transporters carry live
animals between fattening sites, abattoirs, and other premises on a ...
Characterisation of InlA truncation in Listeria monocytogenes isolates from farm animals and human cases in the province of Quebec
(2017-06)
The introduction of Listeria monocytogenes into the food production chain is a concern, with numerous grouped cases of listeriosis associated with milk-derived or pork-derived products have been documented. Management of ...
Chicken Caecal Microbiome Modifications Induced by Campylobacter jejuni Colonization and by a Non-Antibiotic Feed Additive
(2015-07)
Campylobacter jejuni is an important zoonotic foodborne pathogen causing acute gastroenteritis
in humans. Chickens are often colonized at very high numbers by C. jejuni, up to 109
CFU per gram of caecal content, with no ...
Characterization of Endoproteolytic Processing of Dynorphins by Proprotein Convertases using Mouse Spinal Cord S9 Fractions and Mass Spectrometry
(2016-06-01)
Dynorphins are important neuropeptides with a central role in nociception and pain alleviation. Many mechanisms regulate endogenous dynorphin concentrations, including proteolysis. Proprotein convertases (PCs) are widely ...
Dual infections of CD163 expressing NPTr epithelial cells with influenza A virus and PRRSV
(2017-08)
In the pig, respiratory co-infections involving various pathogens are far more frequent than single infections.
Amongst respiratory viruses, swine influenza type A virus (swIAV) and porcine reproductive and respiratory
syndrome ...
Whole genome sequencing of a Canadian Bovine gammaherpesvirus 4 strain and possible link between the viral infection and respiratory and reproductive clinical manifestations in dairy cattle
(2017-06-16)
Bovine gammaherpesvirus 4 (BoHV-4) is a herpesvirus widespread in cattle populations, and with no clear disease association. Its genome contains a long unique coding region (LUR) flanked by polyrepetitive DNA and 79 open ...
