Message from our director
It is with great pleasure that I present to you this GREZOSP annual report.
The report we present to you is that of a busy year, but we are not complaining! While some of you have been overwhelmed with the management of avian influenza H5N1, others have been heavily involved in the ongoing management of the COVID-19 pandemic. Despite all this, we had the great pleasure, this past year, to resume social meetings and face-to-face activities.
In addition to our social activities among members, we contributed to the organization of several scientific events, such as the annual scientific congress of the Centre de recherche en santé publique (CReSP) in Saint-Hyacinthe and the symposium « Mieux travailler ensemble pour un monde en meilleure santé» organized by the Club étudiant pour Une seule santé. We also participated in the organization of two other events that will be featured in next year’s report.
The past year has been marked by great strides for the One Health approach. The Initiative Une seule santé de l’Université de Montréal has now been launched, and we have contributed to it. I am deeply satisfied to see the growing awareness of our approach. I have participated in several events in this regard. Last fall, I was invited to give a presentation at the Colloque Une Seule Santé organized by the University of Calgary and the Royal Society of Canada.
I was also invited to present and explain what the One Health approach is at the Engagement Forum for Partners and Stakeholders of the Pandemic Preparedness Instrument, following the opening of the day by the Deputy Minister of Health, Dr. Stephen Lucas. This forum brought together several federal agencies, provinces, territories, indigenous partners, and civil society organizations to facilitate intersectoral dialogue on pandemic prevention, preparedness, response, and recovery. The event is part of Canada’s participation in the development of an international pandemic instrument. One of the topics discussed was the One Health approach for pandemic prevention, preparedness, and response.
On a more down-to-earth note, the work within our executive committee has been heavier this year due to the absence of our coordinator, but we have managed to maintain the services. We now know that we will no longer have the opportunity to count her as part of our team, so we will soon be recruiting a new resource, which should facilitate our functioning for the coming year.
I hope this activity report is enlightening and enjoyable to read. Happy reading!
Spotlight on GREZOSP-supported student research projects
Katrina Di Bacco, a PhD student under the supervision of Hélène Carabin, a professor at the Faculté de médecine vétérinaire and director of GREZOSP, and co-supervised by Cédric Yansouni, a professor at the Faculty of medicine at McGill University.
« Estimation de la fréquence des zoonoses parasitaires négligées au Canada »
Parasites such as Taenia solium, Toxocara sp., Toxoplasma gondii, Echinococcus sp., and Baylisascaris sp. are responsible for globally significant parasitic zoonoses. In Canada, there is limited data on the prevalence of these parasites.
Katrina’s project aims to estimate the frequency of these parasitic zoonoses in humans and animals. To achieve this, she will review scientific literature to gather data on these zoonoses in Canada. Subsequently, to determine the seroprevalence of selected infections in the Canadian population, she will analyze sera from the Canadian Health Measures Survey (CHMS) biobank, which collects health measurement data from Canadian residents. She will also examine the influence of variables such as age and sex, among others, to identify risk associations.
Raphaëlle Audet-Legault, a master’s student under the supervision of Catherine Bouchard, a researcher at the Public Health Agency of Canada (PHAC), and co-supervised by Cécile Aenishaenslin and Jean-Philippe Rocheleau, professors at the Faculté de médecine vétérinaire:
« Éco-épidémiologie de l’anaplasmose dans l’environnement péri-domestique en Estrie ».
Her project aims to study the reservoirs of human granulocytic anaplasmosis (HGA), a vector-borne disease caused by the bacterium Anaplasma phagocytophilum, which is emerging in Québec. The zoonotic variant known as “human active” (Ap-ha) is pathogenic to humans, horses, and dogs.
During her project, she intends to determine which species of wild micromammals can be considered competent reservoir hosts of the Ap-ha variant, which is currently unknown in the Canadian context. The study will take place in peri-domestic wooded sites in the Bromont region during the summers of 2022 and 2023, where live capture of rodents and tick collection will be conducted. This project adopts a One Health approach, integrating ecological and epidemiological concepts to better understand the emergence of HGA and guide the development of interventions in human and animal health.
Student Club for One Health
The “Club étudiant pour Une seule santé (CÉ USS)” is an active partner of the Initiative Une seule santé de l’Université de Montréal that was created by students from various disciplines such as biology, veterinary medicine, public health, and others. They apply the One Health approach in their research activities. The mission of the club is to promote the transdisciplinary and holistic One Health approach among the student community at the Université de Montréal and various partners.
The club organizes student symposiums during different events to promote the One Health approach and initiate projects in line with this approach. For instance, the symposium held on November 4th, 2022, titled “Mieux travailler ensemble pour un monde en meilleur santé”, brought together a panel of experts and students from various disciplines who gathered to discuss the One Health approach and facilitate its implementation within their institutions and projects. The club also holds workshops to popularize the One Health vision among undergraduate students.

Awards and grants
The GREZOSP is strongly committed to supporting its graduate students. Since its establishment in 2015, the GREZOSP Scholarship Program has distributed over $150,000 to its students, both for their recruitment, end-of-program support, and to enable them to present their findings at international conferences. Many of these graduates are now working as professionals in Québec within organizations such as the PHAC, CFIA, and INSPQ, as well as in France and Niger.
In 2021-2022, the GREZOSP launched its new recruitment scholarship program to promote new talent and support the training of a new generation of researchers and professionals in the field of veterinary epidemiology and the One Health approach.
The recipients of the master’s or doctoral recruitment scholarships, each one of $15,000 for 2022-2023, are Katrina Di Bacco, a doctoral student under the supervision of Hélène Carabin, and Raphaëlle Audet-Legault, a master’s student under the supervision of Catherine Bouchard.
Internship scholarships are also available for projects focused on the epidemiology of zoonoses and population health within a One Health context. A $3,200 scholarship has been awarded to Katherine Albert.
The GREZOSP has also established conference scholarships to support student travel and registration for conferences related to the GREZOSP’s mission. This year’s winners, Agathe Allibert, Laurence Daigle, Natasha Bowser, Nikky Millar, Sarah Mediouni, and William Donnely, received a combined support of $6,500.
In addition, students who are members of GREZOSP are eligible for public health awards and scholarships awarded by the Faculté de médecine vétérinaire during the Annual Awards and Scholarships Ceremony 2021-2022, which took place on March 23, 2023. The Lucie Besner Scholarship of $5,000 was presented to Katrina Di Bacco, a doctoral student under the supervision of Hélène Carabin. The Agria Foundation Prize of $15,000 was awarded to William Lelorel Nankam Nguekap, a master’s student supervised by Juan Carlos Arango Sabogal. Benjamin Jacobek, a master’s student under the supervision of Jean-Philippe Rocheleau, received the Zoological Society Prize ($4,152).
Finally, the Lucie-Dutil Award, ($500), was presented by GREZOSP to Ariane Dumas, a doctoral student under the supervision of Patrick Leighton.
Workshops organized by the GREZOSP
Systems Approaches Workshop
On March 13th and 14th, 2023, GREZOSP organized a workshop on systems approaches. The workshop was conducted by Chloé Clifford Astbury, a postdoctoral researcher at the School of Global Health, University of York in Toronto. Her current work focuses on applying systems approaches to the prevention of communicable and non-communicable diseases, with an emphasis on participatory and qualitative modeling of systems.
During the workshop, Chloé provided an introduction to systems approaches, a set of approaches and methods for studying complex phenomena as systems and understanding how they are interconnected and influence each other. The workshop participants had the opportunity to engage in an interactive session exploring the question, “What are the key variables that impact the frequency of zoonotic transmission events?” They created system maps, time behavior graphs, and developed intervention scenarios.
Social Media Workshop
On March 10th, 2023, Thomas Milan, specializing in scientific communication and popularization to promote access to science for the general public, offered a workshop on effectively using social media as a scientist.
Social media platforms have become essential communication tools for the scientific community, allowing researchers to share ideas, create collaborations, and communicate research findings. During this workshop, participants had the opportunity to explore different social media platorms, learn how to create effective content, and develop their online presence.
Social Event on May 26, 2022
The sunny days inspired Daryna Kurban, a doctoral student from GREZOSP, to organize a gathering for members to enjoy a shared meal. It was a wonderful gathering after a prolonged isolation due to the COVID-19 pandemic.
The event provided a great opportunity for professional networking and getting to know new members.
Léa Delesalle, a doctoral student from GREZOSP, also took the opportunity to present the “initiasciences” project, a nonprofit organization she helped establish in 2021. The project aims to introduce people to research and is supported by various institutions (CEGEPs, research institutions, etc.) and the NovaSciences program of the Ministère de l’économie et de l’innovation, which won the local OSEntreprendre Challenge in 2022.
This year, the Centre de recherche en santé publique (CReSP) held a day of its congress at the Faculté de médecine vétérinaire. Researchers and students from GREZOSP (Groupe de Recherche en Epidémiologie des Zoonoses et Santé Publique) were excited about the opportunity to create new connections under the theme « Regards croisés sur la santé et l’environnement ».
The day started with guided tours of the FMV site. Participants had the chance to explore the small and large animal hospitals (including the famous cow with a window in its side) before attending presentations by researchers and students. The theme sparked lively discussions among the speakers. Many members of GREZOSP actively participated in the proceedings of the day, either through presentations or engaging in the exchanges.
Event on January 9, 2023
In early January 2023, GREZOSP members gathered for a meal to celebrate the new year! Caroline Kilsdonk, a member of the executive committee, took care of organizing and hosting this gathering to kick off the new year. After opening remarks by Director Hélène Carabin and Nicholas Ogden, Caroline presented a video capsule highlighting the importance of the One Health approach, which is deeply embedded in GREZOSP’s projects. She also invited members to share their accomplishments and help promote them. The members then enjoyed a friendly afternoon together, sharing a meal provided by the group
Sucessfully defended theses
Ariane Dumas, a doctoral student supervised by Patrick Leighton, a professor at the Faculté de médecine vétérinaire, and co-supervised by Nicholas Ogden, a researcher at the Public Health Agency of Canada (PHAC).
« Eco-épidémiologie spatiale de la tique à pattes noires et de ses pathogènes dans un parc naturel du sud du Québec ».
In northeastern North America, the Ixodes scapularis tick species is the most common, and it is a vector for several zoonotic pathogens, including the one that causes Lyme disease.
Her project aimed to gather comprehensive data from an urban fringe natural park in southern Québec. The objectives were to identify the environmental determinants of the spatiotemporal distribution of I. scapularis, specify the contribution of host species to the enzootic circulation of its pathogens, identify park characteristics associated with both human visitation and the abundance of infected ticks, and develop a methodology to map the risk of human-tick contact in public parks. The data aimed to demonstrate the importance of fine-scale eco-epidemiological processes in the dynamics of diseases transmitted by this tick.
Hélène Lardé, a PhD student under the supervision of Simon Dufour and co-supervised by Marie Archambault and David Francoz, all professors at the Faculté de médecine vétérinaire.
« Comparaison de méthodes de quantification afin de proposer un système de surveillance de l’utilisation des agents antimicrobiens dans les fermes bovines laitières du Québec ».
Quantifying antimicrobial use (AMU) is a key element of antimicrobial resistance surveillance programs. This thesis aimed to evaluate several methods of quantifying AMU in Québec dairy farms. Specifically, it aimed to define a unit of measurement for antimicrobials suitable for the Canadian context, determine the average annual AMU rate in Québec dairy farms, and compare different quantification methods to identify a potential AMU surveillance method in Québec. An observational cohort study was conducted on a sample of 101 dairy farms. AMU quantification was performed using different methods and compared to one year of data collection on drug packaging and feed mill invoices for medicated feed.
Camille Guillot, a PhD student under the supervision of Patrick Leighton, a professor at the Faculté de médecine vétérinaire, and co-supervised by Catherine Bouchard, a researcher at the Public Health Agency of Canada (PHAC).
« La surveillance sentinelle pour les maladies vectorielles : une étude de cas de la maladie de Lyme au Canada »
In Canada, Lyme disease has been identified as a priority emerging infectious disease. Sentinel surveillance, if effective, can monitor the evolving landscape of a disease. The first objective of this thesis was to evaluate the representativeness of acarological sentinel surveillance in describing the risk of Lyme disease in Québec. The second objective was to develop a standardized holistic approach for the selection of sentinel sites that could optimize the spatial design of the surveillance system, and apply this approach to the creation of a new acarological surveillance network in Canada.
Laurence Daigle, a master’s student supervised by Cécile Aenishaenslin and co-supervised by André Ravel, professors at the Faculté de médecine vétérinaire.
« Connaissances, attitudes et pratiques face aux chiens et aux morsures dans un contexte autochtone nordique »
Her research project aimed to study dog bites in two northern Indigenous communities in Québec. The study revealed that 21% of people in these communities had experienced a dog bite in their lifetime. Furthermore, this research identified a lack of awareness and knowledge about dog bites and the risks of rabies in both communities. Considering that rabies is endemic in the wild canid populations in these regions, these results are particularly worrying. They provide important knowledge for the development of community-based interventions.
Liliana Potes, a master’s student under the supervision of Cécile Aenishaenslin and co-supervised by Jean-Philippe Rocheleau and Catherine Bouchard, professors at the Faculté de Médecine Vétérinaire.
« Évaluation d’une intervention intégrée Une seule santé pour réduire le risque de la maladie de Lyme sur le territoire de la ville de Bromont »
Her project aimed to evaluate an integrated “One Health” intervention in the municipality of Bromont, in Estrie, between 2019 and 2020. This intervention included two components: an environmental component and a community component. The environmental component aimed to reduce the number of ticks infected with Borrelia burgdorferi using an oral acaricide. The community component, directly related to her master’s project, involved a series of activities carried out with the Bromont community to raise awareness among citizens and identify the role of community members in disease prevention through their participation in the project…

« Traitement antibiotique sélectif au tarissement des vaches laitière »
The objective of this thesis was to shed more light on the decisions regarding targeted antimicrobial treatment for infected quarters or cows at dry-off. The results showed that selective treatment would reduce the use of antimicrobials at the time of dry-off, without negative effects on udder health or milk production during the first months of subsequent lactation, if and only if internal teat sealants are used for quarters not treated with antimicrobials. Producers could consider using only the last pre-dry-off somatic cell count (SCC) test as a potential tool to identify cows that should be treated with antimicrobials at dry-off. However, adding a bacteriological milk culture per quarter on Petrifilm® for cows identified as infected based on pre-dry-off SCC data would improve the test’s accuracy and further reduce the use of antimicrobials.
