Stanford gut check shows diversity of intestinal ecosystem

...ical sites inside the large intestine as well as a stool sample. Eckburg and his team determined more than 13,000 sequences of 16S rRNA. Most of what they identified included the usual suspects in the intestinal flora, but there were surprises. Nearly two-thirds of the bacteria they identified were novel,...

... infection. Dr. Hennessey and colleagues tested stool specimens at various intervals following vaccination. Out of a total of 419 adults with HIV infection, no poliovirus was isolated from any of the specimens. Because of these results, it is likely that fewer than 1 percent of adults with HIV infecti...

Researchers use mass spectrometry to detect norovirus particles

... In the Hopkins study, the researchers analyzed a stool sample treated with virus-like particles, which closely resemble norovirus but are noninfectious. Using mass spectrometry, the researchers were able to detect the norovirus capsid protein down to levels typically found in clinical specimens from sick...
