Gut bacteria at a young age can contribute to multiple sclerosis disease onset and progression.
New technique provides deeper look at microbial communities by assessing their biomass.
Thistle tortoise beetles outsource the job of breaking down plant cell walls to a symbiotic bacterium. The genome of this bacterium is the smallest ever sequenced of any organism living outside a host cell. It contains genes that are responsible for the production of pectinases, enzymes that break down pectin. The production of pectinases is the primary function of these bacteria. Without bacterial symbionts the beetles would be unable to survive.
On the occasion of the 10th European Antibiotic Awareness Day, the European Centre for Disease Prevention and Control (ECDC) is releasing its latest EU-wide data on antibiotic resistance, as well as its guidance on prevention and control of carbapenem-resistant Enterobacteriaceae (CRE). In 2016, combined resistance to several antibiotic groups continued to increase for Escherichia coli and Acinetobacter species. This situation is of great concern as patients infected with these multidrug-resistant bacteria have very limited treatment options.
An investigation of the microbial environment at Laguna La Brava in Chile may suggest that novel microorganisms might be at work in the absence of cyanobacteria, according to a study published Nov. 15, 2017 in the open-access journal PLOS ONE by Maria Eugenia Farias from Laboratorio de Investigaciones Microbiológicas de Lagunas Andinas, Argentina, and colleagues.
A new shape-shifting polymer can target and kill Helicobacter pylori bacteria in the stomach without killing helpful bacteria in the gut. Such a treatment could improve the digestive health of billions of people worldwide who contract H. pylori infections. The antimicrobial agent morphs into a bacterial hole-puncher in the stomach's acidic environment and reverts to an amorphous, inactive structure when it reaches the higher pH environment of the small intestine.
Professor Hattori and Professor Kenya Honda of Keio University School of Medicine led research to investigate the relationship between salivary microbes and IBD, and they found that when the bacterium Klebsiella pneumoniae colonizes in an intestine out of microbial balance, immune cells called T helper 1 (TH1) become overactive in the gut, resulting in intestinal inflammation leading to the onset of IBD.
Humans have roughly as many bacterial cells in their bodies as human cells, and most of those bacteria live in the gut. New research released today reveals links between the gut microbiome -- the population of microorganisms living in the gastrointestinal tract -- and brain diseases such as Parkinson's and Alzheimer's, including potential new ways to track and treat these diseases.
With antibiotic resistance on the rise, bacterial contamination of food is becoming more problematic. Now in a study appearing in ACS Biomaterials Science & Engineering, scientists report that they have developed an antibacterial 'sugar-glass' coating in which viruses that destroy bacteria are embedded and are kept stable for up to three months. The coating could someday be used in the food packaging and processing industries to help prevent food-borne illnesses and deaths.
The nearly simultaneous emergence of a gene responsible for producing carbapenemases -- enzymes that kill the most powerful antibiotics used against life-threatening, multidrug-resistant bacterial infections -- coupled with the introduction of a bacterial clone that spread between patients created the 'perfect storm' that led to today's antibiotic resistance epidemic in Colombia.
