The Research Group on Infectious Diseases in Production Animals (GREMIP) of the Faculté de médecine vétérinaire, Université de Montréal, formerly called « Research Group on Infectious Diseases of Swine », was originally formed in 1982 with the emergence of porcine pleuropneumonia (PPP), the initiating event for the creation of this research group. For many years, GREMIP’s researchers have focused on infectious diseases in pigs, becoming international experts in this field. Recognizing that the methods used could be applied to other animal species, our researchers have decided to expand their research activities in the area of infectious diseases in other production animal species.

The research of our members is particularly focussed on the pathogenesis of bacterial and viral infections in animals. Major research themes include molecular and cellular caracterization of virulence factors of pathogenic or zoonotic animal bacteria, such as Actinobacillus pleuropneumoniae, Clostridium perfringens, Escherichia coli, Salmonella spp, Streptococcus suis, Haemophilus parasuis... Using a creative blend of fundamental and applied research, our work aims to improve the control of infections by these pathogens through the development of diagnostic tools and new vaccines. Our researchers also work on antimicrobial resistance in different animal species such as pigs, poultry, and cattle. In addition, the recent recruitment of new researchers permitted the establishment of new research areas on viral infections, such as those due to swine reproductive and respiratory syndrome virus (RRSV), porcine circovirus (PCV-2), he porcine epidemic diarrhea virus (PED) and influenza virus.

GREMIP members supervise over 35 graduate students and post-doctoral fellows and are always enthusiastic to recruit and train motivated students seeking to further their expertise in bacteriology and virology. Through the years, our team of researchers has established important collaborations with nationally and internationally acclaimed scientists. The funding of our researchers’ activities is of the order of 4 million dollars per year and is provided from different granting agencies such CRSNG, FRQNT, MAPAQ, Génome Québec and from the pharmaceutical and food industries. Together, our researchers publish at least 55 articles per year in various internationally renowned scientific journals.

The GREMIP members created the Centre de recherche en infectiologie porcine (CRIP), a strategic group of the FRQNT focussing on pig diseases (2006-2012). With the renewal in 2013, the scope of the research was widened to include poultry, changing the acronym CRIP for CRIPA “Centre de recherche en infectiologie porcine et avicole / Swine and Poultry Infectious Diseases Research Center”
( The CRIPA brings together more than 40 scientists across Quebec with different expertises and affiliated with more than 10 universities and research institutions. The CRIPA uses a multidisciplinary and integrated approach, combining both fundamental and applied research to investigate the complex nature of swine and poultry infections.

As part of the 30th anniversary of the GREMIP in 2012, a short video was created featuring some of our students and members.
