Viruses con bacteria into working for them

Researchers have discovered that certain photosynthetic ocean bacteria should beware of viruses bearing gifts: These viruses are carrying genetic material taken from their previous bacterial hosts that tricks the new host into using its own machinery to activate the genes, a process never before documented in any virus-bacteria relationship.


H5N1 Virus Targets Pulmonary Endothelial Cells
Infection Control Today

Researchers from the Centers for Disease Control and Prevention (CDC), and the University of South Alabama show that the highly pathogenic avian influenza H5N1 virus, but not seasonal influenza viruses, can target the cells of human lung tissue, where they replicate fast and efficiently, and induce inflammation, which correlates with H5N1-induced acute respiratory distress syndrome that is observed in humans.


UNLV scientists isolate rare magnetic Death Valley bacteria

A University of Nevada, Las Vegas microbiologist says he and his team members have identified and cultivated a type of magnetic bacteria in Death Valley that could one day contribute to the biotech industry.


Ulcer-causing bacteria baffled by mucus: Viscoelasticity impact on collective behavior of swimming microorganisms

Researchers at Rensselaer Polytechnic Institute have discovered how certain polymers -- like those found in human mucus and saliva -- make it significantly more difficult for ulcer-causing bacteria to coordinate.


Salmonella Linked to Labs Infected 109
Food Safety News

http://www.foodsafetynews.com/2012/01/salmonella-linked-to-laboratories-infected-109-over-11-months/
Between August 2010 and June 2011, the U.S. Centers for Disease Control and Prevention (CDC) counted 109 people in 38 states infected with a commercial strain of Salmonella Typhimurium most commonly found in microbiology laboratories.


Computer simulation of tuberculosis bacteria could lead to discovery of new ways to fight disease

A Rutgers–Camden professor is using his expertise in computer science to aid in the development of new methods to fight tuberculosis.


Unlocking Seaweed’s Next-Gen Crude: Sugar
New York Times
January 23, 2012
http://green.blogs.nytimes.com/2012/01/23/unlocking-seaweeds-next-gen-crude-sugar/
Seaweed often brings to mind thoughts of surf and sushi, not fuel. But that could change if a biotechnology start-up called Bio Architecture Lab succeeds in building a new kind of energy company from designer bacteria and a low-cost process for harvesting seaweed.


Nanoparticles for a new vaccine against shigellosis
Basque Research

A team of researchers from the departments of Microbiology and Pharmaceutical Technology of the Universidad of Navarra worked on the development of a new oral vaccine in order to treat bacterial dysentery, or  shigellosis.


Extracellular Matrix Identified As Source Of Spreading In Biofilms
MedicalNewsToday
January 25, 2012
http://www.medicalnewstoday.com/releases/240682.php
New research at Harvard explains how bacterial biofilms expand to form slimy mats on teeth, pipes, surgical instruments, and crops. 


Mineral quashes deadly bacterial poisons

A simple mineral supplement — manganese — holds promise as the first successful treatment for hemorrhage-inducing infections caused by some food- and waterborne germs.


Entry point for hepatitis C infection identified

A molecule embedded in the membrane of human liver cells that aids in cholesterol absorption also allows the entry of hepatitis C virus, the first step in hepatitis C infection.
