Projects

Research in the Yeoman lab uses a range of dynamic animal-microbe systems to explore ecological and eco-evolutionary features of host-associated microbial ecosystems to understand:

  • Microbial contributions to host health, nutrition, and physiological and immunological development;
  • The evolutionary features of microbe-microbe interactions (incl. symbioses, interdependencies and niche constructions) and their impact of ecology; and,
  • the evolution of host-associated microbial communities as selective traits.

Understanding the Interactions Among the Early Successional Development of the Ruminant Gut Microbiome, Immune System, and Animal Health

The gastrointestinal tract (GIT) microbiota of production animals are firmly established as key features that underpin animal health, development, and productivity.  Early gut colonization is of particular importance affecting the GIT morphology, and local and systemic biochemistry, and immunology of the animal with critical impacts on nutrition, and neonatal resistance to pathogenic challenge. Although perturbations … Continue reading Understanding the Interactions Among the Early Successional Development of the Ruminant Gut Microbiome, Immune System, and Animal Health

Understanding the Role of Biogenic Amines in Vaginal Dysbiosis & BV

In 2013 we published the first untargeted metabolomic analysis of vaginal samples from women with or without BV. This paper highlighted the biogenic amines, putrescine and cadaverine as important characteristic compounds of symptomatic BV, being directly associated with the clinical sign malodor. Other studies published before and after this work have supported these findings using … Continue reading Understanding the Role of Biogenic Amines in Vaginal Dysbiosis & BV

The Ecological Forces Shaping Rainbow trout Gut Microbes and Their Role In Nutrition

Aquaculture is the fastest growing agricultural sector. The percent contribution of aquaculture to world total fisheries production exceeds that from the capture fisheries. Rainbow trout is an important aquaculture species for food, fish products as well as for recreational purposes. In order to meet the demand of aquaculture for quality feed, research was heightened on … Continue reading The Ecological Forces Shaping Rainbow trout Gut Microbes and Their Role In Nutrition
