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 ...
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 ...
Genetic diversity of group A rotavirus in swine in Canada
(2014-01-09)
Group A rotaviruses (RVA) in pigs have been poorly investigated in Canada. In a continued effort to fill this gap, ten finisher swine farms in Quebec, Canada, were sampled over a nine-month period. The presence of RVA was ...
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 ...
Extensive characterization of Campylobacter jejuni chicken isolates to uncover genes involved in the ability to compete for gut colonization
(2015-05)
Background: Campylobacter jejuni is responsible for human foodborne enteritis. This bacterium is a remarkable
colonizer of the chicken gut, with some strains outcompeting others for colonization. To better understand ...
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 ...
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 ...
Gastric stability and oral bioavailability of colistin sulfate in pigs challenged or not with Escherichia coli O149: F4 (K88)
(2015-10)
The aim of the present study was to investigate the in vitro gastric stability of colistin sulfate (CS) and its antimicrobial activity against Escherichia coli and to study the impact of ETEC O149: F4 (K88) infection in ...
Survival in water of Campylobacter jejuni strains isolated from the slaughterhouse
(2015-01)
Campylobacter jejuni cause gastroenteritis in humans. The main transmission vector is the consumption or handling of
contaminated chicken meat, since chicken can be colonized asymptomatically by C. jejuni. However, water ...
