Effect of deoxynivalenol (DON) mycotoxin on in vivo and in vitro porcine circovirus type 2 infections
(2015-04)Deoxynivalenol (DON) is a mycotoxin produced by Fusarium spp and is a common contaminant of grains in North America. Among farm animals, swine are the most susceptible to DON because it markedly reduces feed intake and decreases weight gain. Porcine ... -
Emergence of a New Swine H3N2 and Pandemic (H1N1) 2009 Influenza A Virus Reassortant in Two Canadian Animal Populations, Mink and Swine
(2011-12)A swine H3N2 (swH3N2) and pandemic (H1N1) 2009 (pH1N1) influenza A virus reassortant (swH3N2/ pH1N1) was detected in Canadian swine at the end of 2010. Simultaneously, a similar virus was also detected in Canadian mink based on partial viral genome ... -
Emergence of a new type of porcine circovirus (PCV) in swine: a type 1 and type 2 PCV recombinant
(2010-07)In late September 2008, tissue samples from piglets experiencing an acute outbreak of porcine reproductive and respiratory syndrome (PRRS) were submitted to the Veterinary diagnostic service of the University of Montreal. Several diagnostic assays were ... -
The emergence of porcine circovirus 2b genotype (PCV-2b) in swine in Canada
(2007-08-01)Since late 2004, the swine industry in the province of Quebec has experienced a significant increase in death rate related to postweaning multisystemic wasting syndrome (PMWS). To explain this phenomenon, 2 hypotheses were formulated: 1) the presence ... -
Epidemiological study of Coxiella burnetii in dairy cattle and small ruminants in Québec, Canada
(Elsevier, 2021-04-25)The bacterium Coxiella burnetii (C. burnetii) can infect a wide range of animals, most notably ruminants where it causes mainly asymptomatic infections and, when clinical, it is associated with reproductive disorders such as abortion. It is also the ... -
Establishment of preliminary reference intervals and cytochemical staining of blood cells in big-bellied seahorses (Hippocampus abdominalis)
(Wiley, 2023-03-10)AbstractBackground: Despite their popularity, hematology reference intervals (RIs) have not been established in big- bellied seahorses (Hippocampus abdominalis).Objective: The objectives of this study were to establish hematologic RIs to compare values ... -
Eucaryotic Expression of the Nucleocapsid Protein Gene of Porcine Circovirus Type 2 and Use of the Protein in an Indirect Immunofluorescence Assay for Serological Diagnosis of Postweaning Multisystemic Wasting Syndrome in Pigs
(2004-07)The purpose of this study was to develop a sensitive, rapid, and inexpensive immunofluorescence assay (IFA) using a recombinant porcine circovirus type 2 (PCV2) nucleocapsid protein for the serological detection of PCV2-specific antibodies in pig sera. ... -
Eugenol and other vanilloids hamper caenorhabditis elegans response to noxious heat
(Springer, 2020-10-29)Eugenol, a known vanilloid, was frequently used in dentistry as a local analgesic in addition, antibacterial and neuroprotective effects were also reported. Eugenol, capsaicin and many vanilloids are interacting with the transient receptor potential ... -
Euthanasia and management of downer cows on farm : online survey
(2019-03)The goal of this survey is to make an inventory of the practices usedon farm to euthanize and manage downers and identify challenges producers face. Our aim is to assemble an overall and representative picture of current practices in order to better ... -
Euthanasie et gestion des bovins non-ambulatoires : sondage électronique
(2019-03)Ce sondage a comme objectif de répertorier les pratiques utilisées pour l’euthanasie et la gestion des bovins laitiers non-ambulatoires à la ferme ainsi que les défis rencontrés par les producteurs. Nous voulons dresser un portrait global et représentatif ... -
Evaluation of multiple reaction monitoring cubed for the analysis of tachykinin related peptides in rat spinal cord using a hybrid triple quadrupole–linear ion trap mass spectrometer
(2014-02)Targeted peptide methods generally use HPLC-MS/MRM approaches. Although dependent on the instrumental resolution, interferences may occur while performing analysis of complex biological matrices. HPLC-MS/MRM3 is a technique, which provides a significantly ... -
Evaluation of recombinant Herpesvirus of Turkey Laryngotracheitis (rHVT-LT) Vaccine against Genotype VI Canadian Wild-Type Infectious Laryngotracheitis Virus (ILTV) Infection
(MDPI, 2021-12-03)In Alberta, infectious laryngotracheitis virus (ILTV) infection is endemic in backyard poultry flocks; however, outbreaks are only sporadically observed in commercial flocks. In addition to ILTV vaccine revertant strains, wild-type strains are among ... -
Evaluation of the safety of multiple intramuscular doses of ketoprofen in bearded dragons (Pogona vitticeps)
(Association of reptilian and amphibian veterinarians, 2022-05-30)Cyclooxygenase (COX) 1 has been shown to increase significantly in inflamed ophidian skin and chelonian muscles. Nonselective COX-1 and COX-2 inhibitors, such as ketoprofen, could therefore reduce inflammation more effectively than preferential COX-2 ... -

Exposure of feral swine (Sus scrofa) in the United States to selected pathogens
(2015-01)Les porcs sauvages (Sus scrofa) sont largement distribués aux États-Unis. En 2011 et 2012, aux États-Unis des échantillons de sérum et d’amygdales furent obtenus de 162 et 37 porcs sauvages, respectivement, afin d’évaluer l’exposition à d’importants ... -
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 ... -
Extensive characterization of Campylobacter jejuni chicken isolates to uncover genes involved in the ability to compete for gut colonization
