FosteraTM PRRS modified live vaccine efficacy against a Canadian heterologous virulent field strain of porcine reproductive and respiratory syndrome virus (PRRSV)

Savard, Christian; Alvarez, Fernando; Provost, Chantale; Chorfi, Younes; D'Allaire, Sylvie; Benoit-Biancamano, Marie-Odile; Gagnon, Carl A. (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 ...

Effect of deoxynivalenol (DON) mycotoxin on in vivo and in vitro porcine circovirus type 2 infections

Savard, Christian; Provost, Chantale; Alvarez, Fernando; Pinilla, Vicente; Music, Nedzad; Jacques, Mario; Gagnon, Carl A.; Chorfi, Younes (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 ...

Impact of Actinobacillus pleuropneumoniae biofilm mode of growth on the lipid A structures and stimulation of immune cells

Hathroubi, Skander; Beaudry, Francis; Provost, Chantale; Martelet, Léa; Segura, Mariela; Gagnon, Carl A.; Jacques, Mario (2016-05-25)

Actinobacillus pleuropneumoniae (APP), the etiologic agent of porcine pleuropneumonia, forms biofilms on biotic and abiotic surfaces. APP biofilms confers resistance to antibiotics. To our knowledge, no studies have examined ...

In vivo effect of deoxynivalenol (DON) naturally contaminated feed on porcine reproductive and respiratory syndrome virus (PRRSV) infection

Savard, Christian; Pinilla, Vicente; Provost, Chantale; Gagnon, Carl A.; Chorfi, Younes (2014-12-05)

Deoxynivalenol (DON), also known as vomitoxin, is the most prevalent type B trichothecene mycotoxin worldwide. Pigs show a great sensitivity to DON, and because of the high proportion of grains in their diets, they are ...

Identification of a novel herpesvirus associated with a penile proliferative lesion in a beluga (Delphinapterus leucas)

Bellehumeur, Christian; Lair, Stéphane; Romero, Carlos H.; Provost, Chantale; Nielsen, Ole; Gagnon, Carl A. (2015-01)

The carcass of an adult male beluga (Delphinapterus leucas) was found beach cast in 2008 on the shore of the St. Lawrence Estuary at Rivière-Ouelle, Quebec, Canada. The carcass was transported to the Faculté de médecine ...

Actinobacillus pleuropneumoniae Possesses an Antiviral Activity against Porcine Reproductive and Respiratory Syndrome Virus

Lévesque, Cynthia; Provost, Chantale; Labrie, Josée; Hernandez Reyes, Yenney; Burciaga Nava, Jorge A.; Gagnon, Carl A.; Jacques, Mario (2014-05)

Pigs are often colonized by more than one bacterial and/or viral species during respiratory tract infections. This phenomenon is known as the porcine respiratory disease complex (PRDC). Actinobacillus pleuropneumoniae ...

In vitro effect of deoxynivalenol (DON) mycotoxin on porcine reproductive and respiratory syndrome virus replication

Savard, Christian; Pinilla, Vicente; Provost, Chantale; Segura, Mariela; Gagnon, Carl A.; Chorfi, Younes (2014-03)

Deoxynivalenol (DON) is a mycotoxin produced by Fusarium spp. Among monogastric farm animals, swine are the most susceptible to DON as it markedly reduces feed intake and decreases weight gain. DON has also been shown ...

Persistence of porcine reproductive and respiratory syndrome virus and porcine circovirus type 2 in bacterial biofilms

Jacques, Mario; Grenier, Daniel; Labrie, Josée; Provost, Chantale; Gagnon, Carl A. (2015)

The aim of this pilot project was to investigate association of viruses with bacterial biofilms. Our preliminary data indicate that important viral pathogens of swine, namely, porcine reproductive and respiratory ...

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

Gagnon, Carl A.; Kist Traesel, Carolina; Music, Nedzad; Laroche, Jérôme; Tison, Nicolas; Auger, Jean-Philippe; Music, Sanela; Provost, Chantale; Bellehumeur, Christian; Abrahamyan, Levon; Carman, Susy; DesCôteaux, Luc; Charette, Steve J. (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 ...

Dual infections of CD163 expressing NPTr epithelial cells with influenza A virus and PRRSV

Provost, Chantale; Hamonic, Glenn; Gagnon, Carl A.; Meurens, François (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 ...
