Gut bacteria can control organ functions
Bacteria in the human gut may not just be helping digest food but also could be exerting some level of control over the metabolic functions of other organs, like the liver, according to research published this week in the online journal mBio®. Thes…
The microbes in our gut regulate genes that control obesity and inflammation
If you are looking to lose weight in the coming year, you may need help from an unexpected place: the bacteria in your gut. That’s because scientists have discovered that the bacteria living in your intestines may play a far more significant role in…
Antibiotics have long-term impacts on gut flora
Short courses of antibiotics can leave normal gut bacteria harbouring antibiotic resistance genes for up to two years after treatment, say scientists writing in the latest issue of Microbiology, published on 3 November.
The researchers believe tha…
Genome of a major member of gut bacteria sequenced
Researchers have completed sequencing the genome of Bacteroides thetaiotaomicron, one of the most prevalent bacteria that live in the human intestine. “Now that the draft sequence of the human genome is complete, it’s critical that we study the environmental forces that regulate our gene expression,” says principal investigator Jeffrey I. Gordon. “Humans enjoy mutually beneficial relationships with billions of bacteria that live in our gut. Discovering how these microbes manipulate our biology to benefit themselves and us should provide new insights about the foundations of our health and new therapeutic strategies for preventing or treating various diseases.”
Gut Bacteria Interact with Intestine to Regulate Blood Supply
Bacteria aren’t always bad. In fact, they can be extremely helpful partners. According to research at Washington University School of Medicine in St. Louis, microbes found naturally in the mouse and human gut interact with intestinal cells, called Paneth cells, to promote the development of blood vessels in the intestinal lining. “This study provides insights into the mutually beneficial partnerships forged between mammals and their native microbes,” says the principal investigator. “These symbiotic relationships probably are most important in the gut, which contains the largest and most complex collection of bacteria.”
