P3-168: FECAL MICROBIAL DIVERSITY IN ALZHEIMER'S PATIENTS

Animal-to-animal variation in fecal microbial diversity among beef cattle.

The intestinal microbiota of beef cattle are important for animal health, food safety, and methane emissions. This full-length sequencing survey of 11,171 16S rRNA genes reveals animal-to-animal variation in communities that cannot be attributed to breed, gender, diet, age, or weather. Beef communities differ from those of dairy. Core bovine taxa are identified.

Association of Fecal Microbial Diversity and Taxonomy with Selected Enzymatic Functions

Few microbial functions have been compared to a comprehensive survey of the human fecal microbiome. We evaluated determinants of fecal microbial β-glucuronidase and β-glucosidase activities, focusing especially on associations with microbial alpha and beta diversity and taxonomy. We enrolled 51 healthy volunteers (26 female, mean age 39) who provided questionnaire data and multiple aliquots of ...

Microbial Diversity: Genetic Diversity Vs Functional Diversity

Diversity is the main descriptor of community structure and is a determining factor in the dynamics and function of ecological communities [1]. However, the latter implicitly differs based on the different types of organisms and their relative abundance within the community which is considered to be significant [2]. Research in microbial ecology focuses on the study of microbial community dynam...
