Billions of bacteria within, essential for immune function, are ours alone Gut bacteria's key role in immunity is tuned to the host species, researchers have found, suggesting that the superabundant microbes lining our digestive tract evolved with us–a tantalizing clue in the mysterious recent spike in human autoimmune disorders. A new study reports that the superabundance of microbial life lining our GI tracts has coevolved with us. These internal bacteria, which are essential...

To the ranks of horses, donkeys, camels and other animals that have served humanity as pack animals or beasts of burden, scientists are now enlisting bacteria to ferry nano-medicine cargos throughout the human body. They reported on progress in developing these "backpacking" bacteria – so small that a million would fit on the head of a pin – here today at the 243rd National Meeting & Exposition of the American Chemical Society (ACS), the world's largest scientific society....

(Ivanhoe Newswire) — Allergic asthma affects more than 100 million people worldwide and its prevalence is increasing on average by 50% every decade! A study suggests that widely used antibiotics may be the cause for the increased incidences and severity of allergic asthma in children. University of British Columbia study is the first of its kind to link kids´ exposure to certain antibiotics, like those in developed countries, to allergic asthma. The human gut is colonized by...

The human digestive system, a hotbed of living bacteria, comes in three variations just as distinct as variations in blood type, according to a study released on Wednesday. These "enterotypes" are found in people around the world and exist independent of race, origin, diet, body mass index (BMI), age and state of health, the study says. Researchers from the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany, collaborators in the international MetaHIT consortium, and...

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...

Scientists have long known that certain types of bacteria boost the immune system. Now, Loyola University Health System researchers have discovered how bacteria perform this essential task. Senior author Katherine L. Knight, PhD. and colleagues report their discovery in a featured article in the June 15, 2010, issue of the Journal of Immunology, now available online. Knight is professor and chair of the Department of Microbiology and Immunology at Loyola University Chicago Stritch School of...

The estimated 1,000 species of bacteria inhabiting healthy human skin are likely necessary for proper body functioning, researchers said. Bacterial colonies reside on different parts of the skin, some in the armpit and belly button, which are akin to tropical rain forests, and others on the forearm, which resembles an arid desert, researchers from the National Institutes of Health told the Los Angeles Times in a story published Saturday. We live in a microbial world, and these things are not...
