Dorival Martins Jr., a Postdoctoral fellow in the Department of Microbiology & Immunology at McGill University, is the award winner of the Relève étoile Jacques-Genest award of the Fonds de recherche du Québec – Santé (FRQS). His Award-winning publication: Superoxide dismutase activity confers (p)ppGpp-mediated antibiotic tolerance to stationary-phase Pseudomonas aeruginosa is published in Proceedings of the National Academy of Sciences.

Over 60% of cystic fibrosis patients also suffer from a chronic infection caused by the Pseudomonas aeruginosa (P. aeruginosa) pathogen, which brings about the progressive deterioration of their lungs. The research conducted by Dorival has shown that P. aeruginosa develops a tolerance to antibiotics when it is deprived of nutrients. The tolerance involves antioxidant enzymes known as superoxide dismutases, which normally prevent oxidative stress in bacteria.

The Relève étoile award (new name for the Étudiants-chercheurs étoiles award) is awarded to student-researchers by each of the three Fonds de recherche du Québec.

The FRQS Relève étoile award is now named after Jacques Genest as a tribute to this great researcher and builder.
