Lactobacillus spp. decrease the susceptibility of Salmonella Typhimurium to the last resort antibiotic azithromycin

L. Blais, L. Couture, I. Laforest-Lapointe, J.-P. Cote

This study shows that Lactobacillus strains increase Salmonella Typhimurium's tolerance to azithromycin through two distinct mechanisms involving envelope homeostasis and metabolic changes.

Boreal moss-microbe interactions are revealed through metagenome assembly of novel bacterial species

S. Ishak, J. Rondeau-Leclaire, M. Faticov, S. Roy, I. Laforest-Lapointe

This study uses shotgun metagenomics to identify novel bacterial species and their metabolic potential in boreal moss microbiomes, showing how host traits and environmental factors shape bacterial communities.

Light prevents pathogen-induced aqueous microenvironments via potentiation of salicylic acid signaling

G. Lajeunesse, C. Roussin-Leveillee, S. Boutin, E. Fortin, I. Laforest-Lapointe, P. Moffett

The paper shows that constant light prevents pathogen-induced water-soaking in plants by enhancing salicylic acid signaling, which counteracts abscisic acid-induced stomatal closure.

Contribution of fungal microbiome to intestinal physiology, early-life immune development and mucosal inflammation in mice

E. van Tilburg Bernardes, V. Kucharova Pettersen, M. W. Gutierrez, I. Laforest-Lapointe, N. G. Jendzjowsky, J.-B. Cavin, F. A. Vicentini, C. M. Keenan, H. R. Ramay, J. Samara, W. K. MacNaughton, R. J. Wilson, M. M. Kelly, K. D. McCoy, K. A. Sharkey, M.-C. Arrieta

This study shows that fungi shape bacterial microbiome ecology and immune development in mice, but bacteria drive major intestinal and inflammatory changes.

Exposure to parasitic protists and helminths changes the intestinal community structure of bacterial microbiota but not of eukaryotes in a cohort of mother-child binomial from a semi-rural setting in Mexico

O. Partida-Rodriguez, M. Nieves-Ramirez, I. Laforest-Lapointe, E. Brown, L. Parfrey, L. Reynolds, A. Valdez-Salazar, L. Thorson, P. Moran-Silva, E. Gonzalez, E. Rascon-Castelo, U. Magana, E. Hernandez, L. Rojas Velazquez, J. Torres, , B. B. Finlay

This study examines how exposure to intestinal parasites affects bacterial and eukaryotic microbiota in a mother-child cohort in Mexico, finding significant bacterial community changes but not eukaryotic ones.
