Selected strains could then be engineered to carry or express . Pertaining to the weak complement fixation ability of secretory IgA, response of innate immune system to microbial antigens bound to IgA is mostly tolerogenic [2]. In contrast to traditional monitoring via grab sampling and laboratory analysis, which is time-consuming, labor-intensive, and provides only a data . This requires a mechanism to eliminate engineered microorganisms if necessary before initiating widespread use of microbiome engineering [27]. Consequently, the depletion of large varieties of both symbiotic and pathogenic bacteria that favourably attune the immune system rendered it prone to immune over reactions, metabolic disorders and cancers [4]. Would you like email updates of new search results? A microbiome is essentially a community of various types of microbes that . Altered microbiome has been found more frequently in patients with infection, autoimmune diseases, allergies and cancer in comparison to healthy individuals, indicating its possible influence on immune system [1517].

Saccharomyces) which on ingestion beneficially influences the nutrition of the host. Consequently, microbiome engineering has been employed for improving human health and agricultural productivity. In advanced agricultural research, rhizosphere microbiome engineering is gaining much attention, as the microbial community has been acknowledged to be a crucial partner of associated plants for their health fitness and yield. It often leads to carcinogenesis, microbial drug resistance and exaltation to virulent prototype. Patients with diseased conditions associated with intestinal dysbiosis, i.e. Host-mediated microbiome engineering (HMME) is a strategy that utilizes the host phenotype to indirectly select microbiomes though cyclic differentiation and propagation. We are working to design bacteria that secrete anti-inflammatory molecules and provide site-specific drug delivery within the intestine. This information can be sent via cellular networks in real-time to users computers and monitors. Microbiome engineering is an experimental method that improves host performance by artificially selecting for microbial communities with specific effects on host fitness.
