This episode features Prof. Jan Suchodolski DACVM PhD from Texas A&M University, discussing the gut microbiome in dogs and other companion animals as part of our series on the role of biotics in animal health. Prof. Suchodolski’s lab focuses on understanding gastrointestinal (GI) diseases in pets and developing diagnostic tests for research and clinical practice. His lab works on building a model of what’s happening with animal health, combining microbiome measures with measures of host health. For example, they found that severe gut microbiome dysbiosis in dogs reflected a greater extent of mucosal damage, contributing to the big picture of GI disease. Certain microbiome features when combined with metabolites are promising biomarkers of GI disease in pets. Test reproducibility is highly important, and treatment tends to be multi-modal. Prof. Suchodolski cautions against direct-to-consumer pet microbiome tests, noting that unvalidated assays are very common.
