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 this zoonotic pathogen considers ... -
Case Report: Esophagitis and pharyngitis associated with avian infectious laryngotracheitis in backyard chickens: 2 cases
(2017-06)Infectious laryngotracheitis (ILT) is a contagious viral respiratory disease of great economic importance for the global poultry industry caused by Gallid herpesvirus 1 (GaHV-1). Lesions of the upper digestive tract caused by this virus have not been ... -
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 viability of the bacteria in ... -
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 discovery and emergence of 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 daily basis. This interconnected ... -
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 of ETEC enterotoxin as well ... -
Post weaning diarrhea in pigs: risk factors and non‑colistin‑based control strategies
(2017)Post-weaning diarrhea (PWD) is one of the most serious threats for the swine industry worldwide. It is commonly associated with the proliferation of enterotoxigenic Escherichia coli in the pig intestine. Colistin, a cationic antibiotic, is widely used ... -
Resistance to colistin : what is the fate for this antibiotic in pig production?
(2016-08)Colistin, a cationic polypeptide antibiotic, has reappeared in human medicine as a last-line treatment option for multidrug-resistant Gram-negative bacteria (MDR-GNB). Colistin is widely used in veterinary medicine for the treatment of gastrointestinal ... -
Incognito, une toxine peut anéantir votre stratégie vaccinale contre le SRRP
(2016-06-01)Les céréales sont une excellente source nutritive tant pour les porcs que pour les micro-organismes. Certains d’entre eux, les champignons, peuvent s’y développer et produire diverses molécules dont des toxines dites mycotoxines (myco- préfixe ... -
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 expressed in the central nervous ... -
Impact of Actinobacillus pleuropneumoniae biofilm mode of growth on the lipid A structures and stimulation of immune cells
(SAGE, 2016-05-25)Actinobacillus pleuropneumoniae (APP), the etiologic agent of porcine pleuropneumonia, forms biofilms on both biotic and abiotic surfaces. APP biofilms confers resistance to antibiotics. To our knowledge, no studies have examined the role of APP ... -

Transcriptional analysis of PRRSV-infected porcine dendritic cell response to Streptococcus suis infection reveals up-regulation of inflammatory-related genes expression
(2016-05-23)The porcine reproductive and respiratory syndrome virus (PRRSV) is one of the most important swine pathogens and often serves as an entry door for other viral or bacterial pathogens, of which Streptococcus suis is one of the most common. Pre-infection ... -
Impact of mash feeding versus pellets on propionic/butyric acid levels and on total Escherichia coli load in the gastrointestinal tract of growing pigs
(2016-03)Feed characteristics may influence the bacterial community composition and metabolic activities in the pig gastrointestinal tract, known to be associated with positive effects on the gut. Use of mash feed is associated with reduced Salmonella ... -
FosteraTM PRRS modified live vaccine efficacy against a Canadian heterologous virulent field strain of porcine reproductive and respiratory syndrome virus (PRRSV)
(2016-01-01)Vaccination is a useful option to control infection with porcine reproductive and respiratory syndrome virus (PRRSV), and several modified live-PRRSV vaccines have been developed. These vaccines have shown some efficacy in reducing the incidence and ... -
Herpesviruses including novel gammaherpesviruses are widespread among phocid seal species in Canada
(2016-01-01)Little is known about herpesviruses in Canadian pinnipeds. We measured prevalence of antibodies to herpesviruses in the sera from Canadian phocid seals by an indirect enzyme-linked immunosorbent assay. Wild harbor seals (Phoca vitulina) and captive ... -
Actinobacillus pleuropneumoniae induces SJPL cell cycle arrest in G2/M-phase and inhibits porcine reproductive and respiratory syndrome virus replication
(2015-12)Background: Porcine reproductive and respiratory syndrome virus (PRRSV) is one of the most important pathogens in the swine industry and causes important economic losses. No effective antiviral drugs against it are commercially available. We recently ... -
Tachykinins Processing is Significantly Impaired in PC1 and PC2 Mutant Mouse Spinal Cord S9 Fractions
(2015-11-01)Substance P (SP) play a central role in nociceptive transmission and it is an agonist of the Neurokinin-1 receptor located in the lamina I of the spinal cord. SP is a major proteolytic product of the protachykinin-1 primarily synthesized in neurons. ... -
