Polar Growth At the Bacterial Scale Reveals Potential New Targets for Antibiotic Therapy
An international team of microbiologists led by Indiana University researchers has identified a new bacterial growth process — one that occurs at a single end or pole of the cell instead of uniform, dispersed growth along the long axis of the cell...
UofL Researcher Determines How Legionnaires’ Bacteria Proliferate, Cause Disease
A University of Louisville scientist has determined for the first time how the bacterium that causes Legionnaires’ disease manipulates our cells to generate the amino acids it needs to grow and cause infection and inflammation in the lungs. The...
Bacteria Responsible for Common Infections May Protect Themselves By Stealing Immune Molecules
Bacteria responsible for middle ear infections, pink eye and sinusitis protect themselves from further immune attack by transporting molecules meant to destroy them away from their inner membrane target, according to a study from Nationwide Children’s...
Common Bacteria Cause Some Colon Tumors By Altering Peroxide-producing Gene
Working with lab cultures and mice, Johns Hopkins scientists have found that a strain of the common gut pathogen Bacteroides fragilis causes colon inflammation and increases activity of a gene called spermine oxidase (SMO) in the intestine. The effect...
Do Bacteria Age? Biologists Discover the Answer Follows Simple Economics
When a bacterial cell divides into two daughter cells and those two cells divide into four more daughters, then 8, then 16 and so on, the result, biologists have long assumed, is an eternally youthful population of bacteria. Bacteria, in other words,...
UT Southwestern Research Could Lead to New Treatments for IBD, Viral Infections
The intestinal ecosystem is even more dynamic than previously thought, according to two studies by UT Southwestern Medical Center researchers published in the latest issue of Science. Taken together, these studies provide a new understanding of the unique...
Bacterial Communication Could Affect Earth’s Climate
Woods Hole Oceanographic Institution (WHOI) scientists have discovered that bacterial communication could have a significant impact on the planet’s climate. In the ocean, bacteria coalesce on tiny particles of carbon-rich detritus sinking through...
European Commission Funds New Research Project to Respond to Unexpected Epidemic Threats Such As E.coli
The European Commission has decided to allocate an additional €12 million from the EU’s Research Framework Programme to reinforce Europe’s capacity for tackling pathogens like the virulent Escherichia coli (E.coli) bacteria that recently...
