Commensal - pathogen interactions in the intestinal tract
In both humans and mice, the intestinal microbiota are essential for development of a mature immune system, and for maintaining immunological homeostasis in the intestinal tract. Although many hundreds of bacterial species colonize the mammalian gut, the balance between these species varies widely between individuals in a population. Importantly, the presence or absence of specific species of b...
متن کاملExploring Host–Commensal Interactions in the Respiratory Tract
Commensal microbes are currently in the limelight in biomedical research because they play an important role in health and disease. Humans harbor an enormous diversity of commensals in various parts of the body, including the gastrointestinal and respiratory tracts. Advancement in metagenomic and other omic approaches, and development of suitable animal models have provided an unprecedented app...
متن کاملCommensal–Pathogen Interactions along the Human Nasal Passages
Bacterial species that commonly reside on surfaces of the human nasal passages (Fig 1) interact with the host along a continuum from beneficial to harmful, i.e., from mutualist to commensal to pathogen. Likewise, the host responds along a continuum from tolerance to damage [1]. In fact, a small number of bacterial species that are prevalent and often abundant members of the nasal microbiota are...
متن کاملA Multi-Omic View of Host-Pathogen-Commensal Interplay in Salmonella-Mediated Intestinal Infection
The potential for commensal microorganisms indigenous to a host (the 'microbiome' or 'microbiota') to alter infection outcome by influencing host-pathogen interplay is largely unknown. We used a multi-omics "systems" approach, incorporating proteomics, metabolomics, glycomics, and metagenomics, to explore the molecular interplay between the murine host, the pathogen Salmonella enterica serovar ...
متن کاملMetabolic Interactions in the Gastrointestinal Tract (GIT): Host, Commensal, Probiotics, and Bacteriophage Influences
Life on this planet has been intricately associated with bacterial activity at all levels of evolution and bacteria represent the earliest form of autonomous existence. Plants such as those from the Leguminosae family that form root nodules while harboring nitrogen-fixing soil bacteria are a primordial example of symbiotic existence. Similarly, cooperative activities between bacteria and animal...
