Montreal organizes rapidly during monkeypox outbreak

Dr. Sapha Barkati's team, with several colleagues from the Research Institute of the McGill University Health Centre (RI-MUHC), worked in collaboration with public health, national and provincial public health laboratories and the various sexually transmitted infection clinics in Montreal to report on the Montreal experience and success in managing and controlling the simian smallpox, or monkeypox (mpox), outbreak. The team would like to acknowledge the exceptional work of Luke B. Harrison, fellow in medical microbiology and infectious diseases, who, in addition to co-authoring a study in The New England Journal of Medicine, was also lead author of a study on the subject in another prestigious journal, Annals of Internal Medicine.

Validation and integration of rapid testing for COVID-19 and TB

In collaboration with a team in Peru (Universidad Peruana Cayetano Heredia), Dr. Madhukar Pai’s team conducted a study to respond to the double burden of disease of COVID-19 and tuberculosis (TB). The study is one of the first investigating the diagnostic accuracy and feasibility of integrated molecular COVID-19 and TB testing on the GeneXpert platform. During her doctoral work supervised by Dr. Pai, Emily MacLean, PhD, led the collaborative study. (The Lancet Microbe, doi: 10.1016/S2666-5247(23)00042-3)

A new mechanism of transmission of drug resistance discovered in eukaryotic cells

Martin Olivier, PhD, is co-principal investigator in a collaboration between the Université de Montréal, the Research Institute of the McGill University Health Centre (RI-MUHC) and McGill University that has uncovered a mechanism for the transmission of drug resistance between Leishmania parasites, which are responsible for a devastating infection known as leishmaniosis. The researchers demonstrated that drug-resistant Leishmania release extracellular vesicles (cell-secreted nanoparticles) that contain drug resistance genes. These resistance genes are transmitted to drug-sensitive (non-resistant) parasites via the vesicles. As the parasites receive these vesicles, they in turn become drug-resistant and more vigorous, which promotes the proliferation of the infection. The study was named one of Quebec Science's Top Ten Discoveries of 2022. (Cell reports, doi:10.1016/j.celrep.2022.111121)
