Lecture 14 Review Q and A (human microbe) Flashcards
Define symbionts, commensals and pathobionts
Symbionts: organisms with known health promoting function
Commensals: permanent residents of the gut that offer no benefit or detriment to you
Pathobionts: permanent residents of micro biome , but could induce pathology
How does maternal exposure impact fetus and newborn?
Babies get a lot of their microflora from mum during birth and breast feeding, so anything that impacts mum will impact infant as well
Bifidobacterium infantis and relationship with breast milk composition
really good for gut bacteria function and for modulating the immune system response in newborns . If a newborn is born vaginally, they will get bifidobacterium, but those born by C-section do not. Breastmilk contains an oligosaccharide that infants cannot digest, so we wonder what purpose it served. Turns out it is food for bifidobacterium.
Adverse health outcomes associated with babies born c-section due to differences in their micro biome compared to that of babies born vaginally
Obesity, asthma, allergic diseases (eczema and rhinitis), Type 1 diabetes, neonatal respiratory distress syndrome, persistent pulmonary hypertension and altered lung function
What was the novel treatment described for C. dificile?
Fecal Transplants
