The microbial population in the air of the New York City subway system is nearly identical to that of ambient air on the city streets. This research, published ahead of print in the journal Applied and Environmental Microbiology, establishes an important baseline, should it become necessary to monitor the subway's air for dispersal of potentially dangerous microbes. Also, the combination of new methodologies in the study, including fast collection of aerosols and rapid sequencing technology,...

We Share More Of Our Germs With Dogs Than We Do With Our Children
2013-04-17 14:38:08

Lee Rannals for redOrbit.com — Your Universe Online Researchers writing in the new online science and biomedical journal eLIFE say parents share more bacteria with family dogs than children. The team, led by the University of Colorado-Boulder, looked at the types and transfer modes of microbes from the guts, tongues, foreheads and palms of 60 American families and their canines. In all, they sampled 159 people and 36 dogs. Researchers swabbed various parts of the body to obtain...

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...


Word of the Day
barratry
  • The offense of persistently instigating lawsuits, typically groundless ones.
  • An unlawful breach of duty on the part of a ship's master or crew resulting in injury to the ship's owner.
  • Sale or purchase of positions in church or state.
