Differences in gut bacteria acquired at birth between 2 delivery methods may be key Caesarean section delivery may double the risk of subsequent childhood obesity, finds research published online in the Archives of Disease in Childhood. Caesarean section delivery has already been linked to an increased risk of subsequent childhood asthma and allergic rhinitis, and around one in three babies born in the US is delivered this way.

Infants are more efficient at digesting and utilizing nutritional components of milk than adults due to a difference in the strains of bacteria that dominate their digestive tracts. Researchers from the University of California, Davis, and Utah State University report on genomic analysis of these strains in the November 2010 issue of the journal Applied and Environmental Microbiology identifying the genes that are most likely responsible for this difference. "Human milk oligosaccharides...

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...

Researchers have discovered that a marine germ typically found on the seaweed used to wrap sushi interacts with internal bacteria in our bodies and helps with the digestive process. According to a group of scientists from the National Centre for Scientific Research (CNRS) in Roscoff, France, an enzyme known as porphyranase helps break down carbohydrates in the cell walls of Porphyra, a red algae that is the main ingredient of the nori sheets used to wrap sushi. The enzyme was also discovered...

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...
