Analysis of resistance nodulation division efflux pumps in Acinetobacter baumannii
Fernando, Dinesh Malinda (2015-01-01)Strains from Canadian hospitals were classified as A. baumannii, A. pitti, or A. osocomialis and the most commonly expressed resistance nodulation division (RND) efflux pump was adeFGH. A collection of A. baumannii isolates ... -
Characterizing immunomodulatory activity of lactic acid bacteria on cell types involved in innate immunity: analysis of the effects of Lactobacillus rhamnosus R0011-derived milk ferments on macrophage polarization and of secretome effects on intestinal epithelial cell cytokine production
Jeffrey, Michael (2015-07-01)Probiotic lactic acid bacteria have been associated with a wide array of host-immune modulatory effects including down-regulation of pro-inflammatory gene transcription and expression following pro-inflammatory challenge, ... -
Effects of dietary fermentable material on innate and adaptive immune measures in male and female rats under resting and immunized conditions
Shastri, Padmaja (2015-02-01)Sex-based differences in immune parameters are well recognized, and recent evidence suggests differences in microbiota composition between sexes, necessitating assessment of effects of dietary fermentable material (DFM) ... -
Effects of prebiotic fibre diets on rat mucosal intestinal and systemic immunity and in vitro mechanistic analysis of anti-inflammatory effects of lactobacillus strains on rat and human intestinal epithelial cells
McCarville, Justin (2012-08-01)Probiotics and prebiotics are emerging household terms, whose claimed health benefits share commonality. Their attributed health benefits include the production or induction of short chain fatty acids, maintaining bowel ... -
Effects of soy and milk ferments on measures of innate immunity: a comparison of effects in normal and microgravity conditions
Masotti, Adriana (2010-07-01)Probiotics can influence intestinal responses and mucosal immunity either directly or indirectly through transient modulation of the endogenous microenvironment or the immune system. During space travel, astronauts experience ... -
Immunomodulatory activity of Lacticaseibacillus rhamnosus R0011: analysis of secretome-mediated impacts on innate immune outcomes in intestinal epithelial cells and antigen presenting cells
Jeffrey, Michael (2021-12-01)Certain lactic acid bacteria (LAB), such as Lacticaseibacillus rhamnosus R0011, are associated with immune modulatory activities including down-regulation of pro-inflammatory gene transcription and expression. While host ... -
Immunomodulatory effects of dietary fibre supplementation: effects on cytokine and antibody production and lymphocyte population profiles
Gannon, Mark (2009-08-01)Gastrointestinal microflora has been shown to have a bi-directional relationship with the host immune system. A variety of fermentable carbohydrate polymers largely pass through the small intestine, providing fermentable ... -
Impact of potato protein supplementation with dietary fermentable materials on immune measures in Sprague-Dawley rats
Wulczynski, Mark (2020-09-01)Bacteria may influence the immune system by fermenting dietary fermentable materials (DFM) that resist digestion and reach the colon intact. This study investigated how resistant protein supplementation could affect the ... -
Influence of dietary interventions on the immune system: an investigation of the impact of omega-3 fatty acids, dietary fermentable materials and high energy diets
Clarke, Sandra T. (2016-12-01)Dietary interventions vary in ability to influence immune activity. Separate investigations were conducted to determine the immune impact of omega-3 fatty acids, dietary fermentable materials (DFM) and high energy (HE) ...
