The existence of certain microorganisms in your gut may bolster the immune system's ability to fend off a herpes viral attack that can cause fatal brain inflammation. Researchers say the findings are the first to suggest that an envelope molecule from a bacterium called Bacteroides fragilis (B. fragilis) might be useful against viral inflammatory diseases. Called capsular polysaccharide A (PSA), the envelope molecule appears to promote protective, anti-inflammatory responses during a viral infection.
Current efforts to tackle antibiotic resistance are 'not nearly radical enough,' a leading scientist says.
Ten percent of the oxygen we breathe comes from just one kind of bacteria in the ocean. Now laboratory tests have shown that these bacteria are susceptible to plastic pollution, according to a study published in Communications Biology. 'We found that exposure to chemicals leaching from plastic pollution interfered with the growth, photosynthesis and oxygen production of Prochlorococcus, the ocean's most abundant photosynthetic bacteria,' says lead author and Macquarie University researcher Dr. Sasha Tetu.
Stressful life events most likely contribute to autoimmune diseases, but scientists don't have a deep understanding of the underlying chain of events. A study on mice published this week in mSystems suggests that the gut microbiota may play a significant role in that connection. Researchers found that the onset of stress caused changes in the intestinal bacteria that, in turn, stimulated the activity of immune cells in a way that increased the likelihood that the body would attack itself.
A University of Oklahoma-led interdisciplinary global study expands the understanding of activated sludge microbiomes for next-generation wastewater treatment and reuse systems enhanced by microbiome engineering. Wastewater treatment and reuse are critical to global health and sustaining a world population predicted to reach 10 billion by 2050.
A new finding by researchers at The University of Texas at Dallas and UT Southwestern Medical Center shows that several species of bacteria reside in bladder tissue of postmenopausal women who experience recurrent urinary tract infections (RUTIs). The results, published online April 17 in the Journal of Molecular Biology, represent the first systematic analysis of biopsies from patients in this population.
A research team at Harvard's Wyss Institute for Biologically Inspired Engineering has developed an approach to co-culture a complex human gut microbiome in direct contact with intestinal tissue for at least five days using 'organ-on-a-chip' (Organ Chip) microfluidic culture technology.
Princeton researchers have discovered that Pseudomonas bacteria can detect the speed (shear rate) of flow regardless of the force. By linking the flow-detecting gene to one responsible for illumination, they have bioengineered a real-time visual speedometer: The faster the flow, the brighter the glow.
Northwestern University researchers have found that the enzyme responsible for the methane-methanol conversion in methanotrophic bacteria catalyzes the reaction at a site that contains just one copper ion. This finding could lead to newly designed, human-made catalysts that can convert methane -- a highly potent greenhouse gas -- to readily usable methanol with the same effortless mechanism.
A new study led by researchers at the Johns Hopkins Bloomberg School of Public Health finds that the spread of carbapenem-resistant Enterobacteriaceae (CRE) -- bacteria that have high levels of resistance to most antibiotics -- could be reduced if only 25 percent of the largest health care facilities in a region used a patient registry, a database that can track which patients are carrying CRE.
