ANSC 1111 Lecture 3: Animal Nutrition Lecture 3
Document Summary
Things we can look at under a microscope - microbes (organism) Help keep tight junctions in small intestine to keep pathogens from seeping out into the blood. Stimulate tissue to grow in the correct way. Human microbiome project (completed in 2012, funded by nih) Analyzed feces from healthy people to see the microbes and their genes that are living in our digestive tract. Sequencing 16s rrna (from ribosomes) to identify the type of bacteria. Looks at genes even if bacteria is dead instead of identifying by size, shape, what they eat. Up until the age of 3, the amount of microbes we have increases rapidly. Microbiome are affected in times of transition (weaning) Host benefits aid in food digestion, b-vitamins, development of digestive tract growth and immune function. Microbe benefits home (moist, dark, food, no oxygen), nutrients (break down food we have eaten) 10^11 cells/ml in colon **most microbes in cecum and large intestine.
