Immunology and Pathology Symposium: Immunity, Nutrition, Genomics, and Gut Microbiota
Direct fed microbials (DFMs) are used in animals and humans as dietary supplements to improve health. In recent years, increased scrutiny by the Food and Drug Administration, regarding the use of subtherapeutic levels of antibiotics in food animal production has stimulated new interest in DFMs. Currently, our understanding of the mechanism(s) of action of DFMS and the factors that influence the...
متن کاملFunctional genomics of Lactobacillus casei establishment in the gut.
Although the composition of the gut microbiota and its symbiotic contribution to key host physiological functions are well established, little is known as yet about the bacterial factors that account for this symbiosis. We selected Lactobacillus casei as a model microorganism to proceed to genomewide identification of the functions required for a symbiont to establish colonization in the gut. A...
متن کاملGenomics of the Genus Bifidobacterium Reveals Species-Specific Adaptation to the Glycan-Rich Gut Environment.
Bifidobacteria represent one of the dominant microbial groups that occur in the gut of various animals, being particularly prevalent during the suckling period of humans and other mammals. Their ability to compete with other gut bacteria is largely attributed to their saccharolytic features. Comparative and functional genomic as well as transcriptomic analyses have revealed the genetic backgrou...
متن کاملHidden Diversity in Honey Bee Gut Symbionts Detected by Single-Cell Genomics
Microbial communities in animal guts are composed of diverse, specialized bacterial species, but little is known about how gut bacteria diversify to produce genetically and ecologically distinct entities. The gut microbiota of the honey bee, Apis mellifera, presents a useful model, because it consists of a small number of characteristic bacterial species, each showing signs of diversification. ...
متن کاملPhylogenomics and comparative genomics of Lactobacillus salivarius, a mammalian gut commensal
The genus Lactobacillus is a diverse group with a combined species count of over 200. They are the largest group within the lactic acid bacteria and one of the most important bacterial groups involved in food microbiology and human nutrition because of their fermentative and probiotic properties. Lactobacillus salivarius, a species commonly isolated from the gastrointestinal tract of humans and...
