Capsular sialic acid of Streptococcus suis serotype 2 binds to swine influenza virus and enhances bacterial interactions with virus-infected tracheal epithelial cells
Wang, Yingchao; Gagnon, Carl A.; Savard, Christian; Music, Nedzad; Srednik, Mariela; Segura, Mariela; Lachance, Claude; Bellehumeur, Christian; Gottschalk, Marcelo (2013-12)Streptococcus suis serotype 2 is an important swine bacterial pathogen, and it is also an emerging zoonotic agent. It is unknown how S. suis virulent strains, which are usually found in low quantities in pig tonsils, manage to cross the first host ... -
Coinfections and their molecular consequences in the porcine respiratory tract
Saade, Georges; Deblanc, Céline; Bougon, Juliette; Marois-Créhan, Corinne; Fablet, Christelle; Auray, Gaël; Belloc, Catherine; Leblanc‑Maridor, Mily; Gagnon, Carl A.; Zhu, Jianzhong; Gottschalk, Marcelo; Summerfeld, Artur; Simon, Gaëlle; Meurens, François; Bertho, Nicolas (BMC, 2020-06-16)Understudied, coinfections are more frequent in pig farms than single infections. In pigs, the term “Porcine Respiratory Disease Complex” (PRDC) is often used to describe coinfections involving viruses such as swine Influenza A Virus (swIAV), Porcine ... -
Exposure of feral swine (Sus scrofa) in the United States to selected pathogens
Baroch, John A.; Gagnon, Carl A.; Lacouture, Sonia; Gottschalk, Marcelo (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 ... -
Genetic diversity of Mycoplasma hyopneumoniae isolates of abattoir pigs
Charlebois, Audrey; Marois-Créhan, Corinne; Hélie, Pierre; Gagnon, Carl A.; Gottschalk, Marcelo; Archambault, Marie (2014-01)Mycoplasma hyopneumoniae, the causative agent of porcine enzootic pneumonia, is present in swine herds worldwide. However, there is little information on strains infecting herds in Canada. A total of 160 swine lungs with lesions suggestive of enzootic ... -
Potential use of a recombinant replication-defective adenovirus vector carrying the C-terminal portion of the P97 adhesin protein as a vaccine against Mycoplasma hyopneumoniae in swine
Okamba, Faust René; Arella, Maximilien; Music, Nedzad; Jia, Jian Jun; Gottschalk, Marcelo; Gagnon, Carl A. (2010-07)Mycoplasma hyopneumoniae causes severe economic losses to the swine industry worldwide and the prevention of its related disease, enzootic porcine pneumonia, remains a challenge. The P97 adhesin protein of M. hyopneumoniae should be a good candidate ... -
Transcriptional analysis of PRRSV-infected porcine dendritic cell response to Streptococcus suis infection reveals up-regulation of inflammatory-related genes expression
Auray, Gaël; Lachance, Claude; Wang, Yingchao; Gagnon, Carl A.; Segura, Mariela; Gottschalk, Marcelo (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 ... -
Transcriptional approach to study porcine tracheal epithelial cells individually or dually infected with swine influenza virus and Streptococcus suis
Dang, Yuan; Lachance, Claude; Wang, Yingchao; Gagnon, Carl A.; Savard, Christian; Segura, Mariela; Grenier, Daniel; Gottschalk, Marcelo (2014-04)Background: Swine influenza is a highly contagious viral infection in pigs affecting the respiratory tract that can have significant economic impacts. Streptococcus suis serotype 2 is one of the most important post-weaning bacterial pathogens in swine ...
