Caltech The human body is full of tiny microorganisms—hundreds to thousands of species of bacteria collectively called the microbiome, which are believed to contribute to a healthy existence. The gastrointestinal (GI) tract—and the colon in particular—is home to the largest concentration and highest diversity of bacterial species. But how do these organisms persist and thrive in a system that is constantly in flux due to foods and fluids moving through it? A team led by California...

STOCKHOLM, November 10, 2010 /PRNewswire-FirstCall/ -- The study shows that L. reuteri Prodentis acts synergistically with standard treatment (scaling and root plaining, SRP) to significantly reduce probing pocket depth (PPD) and clinical attachment level (CAL) which are the two most important parameters to assess the severity of periodontitis. Furthermore L. reuteri Prodentis reveals - as the first probiotic ever - significant reductions of three different pathogens in patients with...

Healthy pregnant women can be at risk for pregnancy problems caused by oral bacteria. Researchers from Case Western Reserve University have begun to understand how and which bacteria from the 700 species living in the mouth are responsible for the increasing numbers of preterm and stillbirths. Yiping Han, from the department of periodontics in the School of Dental Medicine, led the study that found several new bacteria originating in the mouth travel through the blood to cause an inflammatory...

Scientists in the USA have discovered why smokers may be more prone to chronic gum disease (periodontitis). One of the bacteria responsible for this infection responds to cigarette smoke "“ changing its properties and the way it infects a smokers mouth. The study published recently in the Society for Applied Microbiology journal Environmental Microbiology, showed that the bacterium Porphyromonas gingivalis adapts and changes its DNA and membrane proteins in response to cigarette smoke....

Study objectives: Poor dental hygiene has been linked to respiratory pathogen colonization in residents of long-term care facilities. We sought to investigate the association between dental plaque (DP) colonization and lower respiratory tract infection in hospitalized institutionalized elders using molecular genotyping. Methods: We assessed the dental status of 49 critically ill residents of long-term care facilities requiring intensive care treatment. Plaque index scores and quantitative...
