The intestine is the largest immune organ of the body. The gut is the most microbially rich part of the body, with approximately 1014bacteria present in the human gut and 400–1000 species that can be cultured with current technology8,9,10. The balance of such a large internal microflora ...
growth curves were generated for 1/2 MM with different concentrations of candidate metabolites. A 10 µL suspension of bacteria (OD600 = 0.1) was inoculated into a 2-mL centrifuge tube containing 800 µL of liquid 1/2 MM medium with candidate metabolites or DMSO (control). A 96-we...
Quantitative and qualitative bacteriological studies were conducted on sea water utilized in laboratory culture of American oyster larvae (Crassostrea virginica).The generic diversity of bacteria isolated from a laboratory seawater storage tank did not change during a 15-day sampling period, although ...
Inflammatory Bowel Disease (IBD), a chronic nonspecific intestinal inflammatory disease, is comprised of Ulcerative Colitis (UC) and Crohn’s Disease (CD). IBD is closely related to a systemic inflammatory reaction and affects the progression of many int
Bacteriophages—or phages—are viruses that infect bacteria and are present in large concentrations in the mucosa that cover the internal organs of animals. Immunoglobulin (Ig) domains on the phage surface interact with mucin molecules, and this has been
