Fish farming in Quebec and antibiotic resistance by Aeromonas salmonicida subspecies salmonicida: issues, solutions and perspectives You can register here. In Quebec, freshwater aquaculture is particularly dedicated to the breeding of salmonids for the stocking of lakes for sport fishing and, to a lesser extent, for direct consumption (groceries, restaurants, etc.). Fish farming in Quebec is facing several challenges, but one of the main ones is the recurrent episodes of infe

Antibiotic Resistance in a “one health” context: The Animal/Environment Sectors You can register here. The discovery of antibiotics once revolutionised human medicine. These therapeutic agents were considered the magic bullet to solve all human infections. However, it was not long until it was discovered that microorganisms were resistant to antimicrobials. Although antimicrobial resistance (AMR) is primarily a natural process, the indiscriminate use of antimicrobials in huma

Networked Collective Microbiomes and the Rise of Sub-cellular “Units of Life” You can register here. Microbiomes are generally conceived of as one element of a pair – their partner being the habitat they occupy. I call this common scientific practice “pair-thinking”. Research into antimicrobial resistance and its underlying anthropogenic drivers highlight the growing footprint occupied by mobile genetic elements (MGEs). Furthermore, these MGEs are known to circulate widely be

"Passive monitoring of airborne antimicrobial resistance genes: a new road" You can register here. Paul BL George will discuss the use of car pollen filters and conifer needles as passive monitors of airborne antimicrobial resistance genes.

Congratulations to Caroline Duchaine who is ranked 2nd on the worldwide list generated by Expertscape in the field of air microbiology. This international recognition demonstrates the excellence of her research and her team. Marc Veillette is not far behind, with a 9th place! Congratulations! Expertscape Expertscape searches the PubMed database to find all journal articles published on a topic in the last ten years. It assigns a score to each article based on an algorithm and

Joanie Lemieux doctoral exam   « Émissions de bioaérosols agricoles : culturomique, sélection/expression et caractérisation des éléments génétiques de résistance aux antibiotiques et contribution au transport longues distances. »   Thursday, December 16 at 1:30 p.m. Room VCH-2810 Alexandre-Vachon Ms. Joanie Lemieux, from the Department of Biochemistry, Microbiology and Bioinformatics, will present her thesis entitled « Émissions de bioaérosols agricoles : culturomique, sélect

Reducing the use of antibiotics in animal production: is it worth the effort? Experience and lessons learned from the poultry industry in Québec You can register here.   In a global effort to reduce the importance of antimicrobial resistance (AR), the Chicken Farmers of Canada have started implementing, in May 2014, its Responsible Antimicrobial use (AMU) Strategy that aimed at gradually eliminating the preventive use of medically important antibiotics for humans in poultry p

Selective culturomic to study antibiotic-resistant bacteria You can register here.   The growing popularity of genomic analyzes enable the characterization of different microbiota and the study of their structure. However those high throughput analyzes are not immune from bias. Despite their advantages, these techniques do not allow the study of minority populations and those considered to be unculturable. Selective culture approaches are use to overcome the weaknesses of gen

On Friday, October 15, the members of the Duchaine laboratory had the honour of welcoming Mona Nemer, the Chief Scientific Advisor to the Prime Minister of Canada. The team was on-site to present their researches. Congratulations to everyone! We can be proud.

Jimmy D. Dikeakos, Ph.D, associated Professor in the Department of microbiology et immunology at Western University and President of the Canadian Society for Virology will comment the article published in PNas "Reverse-transcribed SARS-CoV-2 RNA can integrate into the genome of cultured human cells and can be expressed in patient-derived tissues". You are cordially invited to a “Journal Club” with Jimmy Dikeakos, President of the Canadian Society for Virology and Professor at

"iAM.AMR: An Integrated Assessment Model for Antimicrobial Resistance in a Canadian Context"Antimicrobial resistance (AMR) is a complex and growing public health problem that threatens the health of people and animals around the world. Because of its complexity, it is very hard to predict the impact of actions and policies to combat AMR, and better tools are nee

Important article to read in the Aerosol Science and Technology Journal. Here is the abstract for those who would be interested: A better description of airborne transmission routes of viruses that are responsible for nosocomial infections requires efficient and accurate sampling methods that allow the preservation of viral integrity and infectivity. The aim of this project was to compare the virus collection efficiency of traditional filter sampling using cassettes with wate
