Thesis gut microbiota

Homeostatic innate immune defects may lead to impaired early responses to pathogens. These findings reveal that gut bacteria direct innate immune cell development via promoting hematopoiesis, contributing to our appreciation of the deep evolutionary connection between mammals and their microbiota.

Indeed, following systemic infection with Listeria monocytogenes, germ-free and oral antibiotic-treated mice display increased pathogen burden and acute death. In addition inadequate scientific rigour has been applied to the science of probiotics.

Little is known about the potential of novel therapeutic strategies, such as probiotics, to modulate diseases such as NEC. Study of the role that the microbiota may play in the development of such diseases may lead to new therapies to modulate or even cure them.

Although molecular techniques can identify species independent of standard cultures they can enlighten little on the metabolic activity of identified bacterial species, which may be important in the propagation of inflammatory responses.

Gut microbiota promote hematopoiesis to control bacterial infection

The aims of the study described in this dissertation were to test the following hypotheses. Quantitative measurement of the metabolic activity of the unculturable gut microbiota is a useful way of studying changes in the microbiota, compared with measures of bacterial diversity, and may enlighten our understanding of bacterially mediated inflammatory stimuli in inflammatory gut diseases of childhood.

We reveal that germ-free mice display reduced proportions and differentiation potential of specific myeloid cell progenitors of both yolk sac and bone marrow origin. They are increasingly implicated in the pathogenesis of acquired inflammatory diseases of the gut in childhood, namely: However, it remains unknown whether gut microbiota control immunity through regulation of hematopoiesis at primary immune sites.

Recolonization of germ-free mice with a complex microbiota restores defects in myelopoiesis and resistance to Listeria. The human gut microbiota can be labelled by stable isotope probing SIP to measure metabolic activity.

Gut microbiota promote hematopoiesis to control bacterial infection Citation Khosravi, Arya Gut microbiota promote hematopoiesis to control bacterial infection. However many current techniques depend on the ability to study such bacteria outwith their natural ecosystem.The commensal microbiota impacts specific immune cell populations and their functions at peripheral sites, such as gut mucosal tissues.

However, it remains unknown whether gut microbiota control.
