Dr. Tom Sharpton's lab (OSU Microbiology) is investigating the effects of environmental stressors such as water temperature, pathogens and antibiotics on the salmonid gut microbiome.   Intestinal microorganisms found in animals are beneficial to host health.  However, both wild and hatchery salmonids are increasingly subject to environmental conditions, such as high water temperature due to climate change, that may disrupt potential benefits provided by the intestinal microbes.  These studies will help us understand how intestinal microorganisms may be contributing to the health of the salmonid host.
