Dept of Microbiology Seminar by Ellen Lark, Ph.D , DVM - "Biogeography and Invasion in Host-Associated Microbiomes"

Biogeography and Invasion in Host-Associated Microbiomes

Microorganisms form complex ecosystems that perform many of the basic
ecosystem processes of larger systems. Because bacteria form a large portion
of these assemblages, their communities make good models for study of many
of these processes. One such community is the intestinal microbiome in
mammals. In this series of studies, 16S rRNA was used to determine the
bacterial community of the lower mouse intestinal microbiome and determine
the biogeography of that community. The biogeography of the lower intestine
potentially influences how ecosystem developments, such as invasion, take
place in the gut. Clostridium difficile was used to demonstrate how an invasive
organism might take advantage of disturbance in the intestinal microbiome to
colonize the intestine. Our current research on the fish mucosal microbiome is
focused on similar processes that may occur during colonization of
Flavobacteria in coldwater disease in Lake Trout (Salvelinus namaycush)
