Gut type can explain efficiency of uptake of nutrients and medicines "The three gut types can explain why the uptake of medicines and nutrients varies from person to person," says bioinformatician Jeroen Raes of the VIB and Vrije Universiteit Brussel, one of the two lead researchers in the study. "This knowledge could form the basis of personalized therapies. Treatments and doses could be determined on the basis of the gut type of the patient." Improved knowledge of the gut types could also...

Scientists have completed the most comprehensive comparative analysis to date of bacterial communities inhabiting the human nose and throat, which could provide new insights into why some individuals become colonized with pathogens while others do not. They release their findings today in mBioâ“ž¢ the online open-access journal published by the American Society for Microbiology. "The nose and throat are important sites of pathogen colonization, yet the microbiota...

Increased appetite and insulin resistance can be transferred from one mouse to another via intestinal bacteria, according to research being published online this week by Science magazine. The finding strengthens the case that intestinal bacteria can contribute to human obesity and metabolic disease, since previous research has shown that intestinal bacterial populations differ between obese and lean humans. "It has been assumed that the obesity epidemic in the developed world is driven by an...

U.S. researchers reported on Wednesday that people with the most germs in their mouths are the most likely to have heart attacks. The researchers said that their study compared heart attack victims to healthy volunteers and found the heart patients had higher numbers of bacteria in their mouths. Their findings add to a growing body of evidence that oral hygiene is linked to overall health. Oelisoa Andriankaja and colleagues at the University at Buffalo, New York were trying to find if any...

By Allison M. Heinrichs Beneath two miles of ice in Greenland, a novel species of unusually small yellow-orange bacteria has been lying dormant for 120,000 years. On Tuesday, Pennsylvania State University researchers announced they "awakened" the bacteria. "This organism could have some very unique and useful properties, including perhaps biotechnical ones, like novel enzymes for making antibiotics," said co-discoverer Vanya Miteva, a senior research associate at Penn State. The...

A team of Penn State scientists has discovered a new ultra-small species of bacteria that has survived for more than 120,000 years within the ice of a Greenland glacier at a depth of nearly two miles. The microorganism's ability to persist in this low-temperature, high-pressure, reduced-oxygen, and nutrient-poor habitat makes it particularly useful for studying how life, in general, can survive in a variety of extreme environments on Earth and possibly elsewhere in the solar system. The work...

WASHINGTON -- The size of your gut may be partly shaped by which microbes call it home, according to new research linking obesity to types of digestive bacteria. Both obese mice - and people - had more of one type of bacteria and less of another kind, according to two studies published Thursday in the journal Nature. A "microbial component" appears to contribute to obesity, said study lead author Jeffrey Gordon, director of Washington University's Center for Genome Sciences. Obese humans and...
