Abnormal gut bacteria in premature babies can be found days before the onset of necrotizing enterocolitis (NEC) finds new research in BioMed Central's open access journal Microbiome. Babies who later went on to develop NEC had a lower diversity of gut bacteria 4-9 days after birth, increased level of Firmicutes or Enterobacteriaceae, and lacked the Propionibacterium found in healthy babies. NEC is a common but devastating problem of premature babies - affecting about 10% of infants born at...

Newcastle University scientists have revealed the mechanism that causes a slime to form, making bacteria hard to shift and resistant to antibiotics. When under threat, some bacteria can shield themselves in a slimy protective layer, known as a biofilm. It is made up of communities of bacteria held together to protect themselves from attack. Biofilms cause dental plaque and sinusitis; in healthcare, biofilms can lead to life threatening and difficult to treat infections, particularly on...

DNA Of Ancient Microorganisms Provide Clues On Origins Of Life
2013-03-08 11:41:26

April Flowers for redOrbit.com - Your Universe Online Important genetic clues about the history of a group of ancient microorganisms called archaea and the origins of life itself have been discovered by a team of researchers. Results of this first-of-its-kind study shed light on one of Earth's oldest life forms. "Archaea are an ancient form of microorganisms, so everything we can learn about them could help us to answer questions about the origin of life," explained William Whitman,...

Seaweed Bacteria Treats Sinusitis
2013-02-19 21:28:42

Brett Smith for redOrbit.com — Your Universe Online By studying a common marine bacterium, a team of international scientists may have found an important treatment for chronic sinusitis, a condition that plagues millions of people every year. Led by researchers from Newcastle University, the team isolated an enzyme from Bacillus licheniformis, a bacterium found on the surface of seaweed capable of dispersing the extracellular DNA in biofilms that protect the bacteria responsible...

Oceans Have Been The Stage For Earth's Longest Ongoing Battle Between Bacteria And A Virus
2013-02-14 13:55:19

April Flowers for redOrbit.com - Your Universe Online A new study led by Oregon State University reveals that the greatest battle in Earth's history has been going on for hundreds of millions of years. And the battle, which no one knew existed until now, is far from over. The findings of this study were published in a recent issue of Nature. On one side of the battle lines stands SAR11, a bacterium that´s the most abundant organism in the oceans, surviving where most other cells...

Practices may affect health in later life Method of birth (vaginal birth s. cesarean delivery) and feeding practices (breastfeeding v. formula-feeding) influence the development of gut bacteria in newborns and thus may affect lifelong health, according to a new study in CMAJ (Canadian Medical Association Journal). Bacteria in the gut play an important role in health, helping digest food, stimulating the development of the immune system, regulating bowels and protecting against...

In their natural environment bacteria develop by forming communities of micro-organisms called biofilms that afford them greater resistance. These biofilms on farms and premises where food is processed lead to considerable economic losses besides being a potential source of contamination and transmission of the pathogen. In her PhD thesis,VioletaZorraquino-Salvo has studied a specific protein type that activates the formation of biofilm in Salmonella and regulates bacterial...

Children with eczema have a more diverse set of bacteria in their guts than non affected children, finds a new study in BioMed Central's open access journal BMC Microbiology. The types of bacteria present were also more typical of adult gut microbes than for toddlers without eczema. Eczema is a chronic inflammation of the epidermis. The gut bacteria of children with or without eczema was examined when they were six and 18 months old. At six months all the infants had the same types of...

DOE/Lawrence Berkeley National Laboratory Berkeley Lab scientists join an international collaboration to understand how archaea and bacteria work together deep in a cold sulfur spring In the fall of 2010, Hoi-Ying Holman of the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) was approached by an international team researching a mysterious microbial community discovered deep in cold sulfur springs in southern Germany. "They told me what they were doing...

  • A fool; a simpleton: a term of abuse common in Ireland and to a less extent in the Gaelic-speaking parts of Scotland.
This word is partly Irish in origin.
