A mounting tide of scientific evidence suggests that the old adage from Aesop's fables "” "You are known by the company you keep" "” also applies to the trillions of microscopic bacteria and viruses that live on the human body. Humanity's invisible but constant companions "” more bacteria hang out on the palms of your hands than there are people on Earth "” is the topic of an article in the current edition of Chemical & Engineering News (C&EN), ACS' weekly...

The human body is home to a complex ecosystem of microbes increasingly recognized as having a critical role in both health and disease. Viruses can attack and change the composition of bacterial communities, yet little is known about how this might influence human health. In a study published online today in Genome Research (www.genome.org), scientists have performed the first metagenomic analysis of a bacterial immune system in humans over time, finding that the defenses of the oral...

HOUSTON, Sept. 7 /PRNewswire-USNewswire/ -- The National Institutes of Health (www.nih.gov) today announced expanded funding of the Baylor College of Medicine Human Microbiome Project clinical program initiated last year at Texas Children Hospital (www.texaschildrens.org). The program will receive $3.4 million over three years to broaden the current study of pediatric abdominal pain and irritable bowel syndrome. A key question will be how human microbes affect pain signaling in the...

Home to a diverse range of microorganisms, a healthy human body contains at least tenfold more bacteria cells than human cells. The most abundant and diverse microbial community resides in the intestine, and changes to the gut microbiota are linked with diseases such as ulcerative colitis and Crohn's disease. In a report published online today in Genome Research (www.genome.org), researchers have analyzed the long-term effects of gut bacterial transplantation in rats, revealing crucial...

At birth, your body was 100-percent human in terms of cells. At death, about 10-percent of the cells in your body will be human and the remaining 90-percent will be microorganisms. That makes you a "supraorganism," and it is the interactions between your human and microbial cells that go a long way towards determining your health and physical well-being, especially your resistance to infectious diseases. To learn more about the community of symbiotic microbes that outnumber our own somatic...

Diversity of human microbes greater than previously predicted The Human Microbiome Project (HMP) on Thursday published an analysis of 178 genomes from microbes that live in or on the human body. The researchers discovered novel genes and proteins that serve functions in human health and disease, adding a new level of understanding to what is known about the complexity and diversity of these organisms. The human microbiome consists of all the microorganisms that reside in or on the human body....

Consortium Finds Greater Microbial Diversity in Human Microbiome than Previously Known ROCKVILLE, Md., May 20 /PRNewswire-USNewswire/ -- Researchers from the J. Craig Venter Institute, a not-for-profit genomic research organization, have published (along with other members of the National Institutes of Health (NIH) Human Microbiome Jumpstart Reference Strains Consortium), a catalog of 178 microbial reference genomes isolated from the human body. Other members of the Consortium are: Baylor...

The human species is dependent for its survival on the billions of microorganisms that inhabit multiple environmental niches within and on the human body. While microbes are commonly associated with diseases and infections, they are also vital in essential, beneficial roles such as digestion, where they help synthesize vitamins and ferment complex indigestible carbohydrates. The overwhelming majority of microbial species (>99%) resist cultivation in the laboratory. However, recent advances...

The thousands of bacteria, fungi and other microbes that live in our gut are essential contributors to our good health. They break down toxins, manufacture some vitamins and essential amino acids, and form a barrier against invaders. A study published today in Nature shows that, at 3.3 million, microbial genes in our gut outnumber previous estimates for the whole of the human body. Scientists at the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany, working within the...

Gastroesophageal reflux diseases , or GERD, affects about 10 million people in the United States, yet the cause and an unexpected increase in its prevalence over the last three decades remains unexplainable. Now, researchers have discovered that GERD is associated with global alteration of the microbiome in the esophagus. The findings, reported in the August 1, 2009 issue of Gastroenterology, may provide for the foundation for further study of the condition as a microecological disease with...
