A team of University of British Columbia microbiologists has identified a key defence mechanism used by the immune system against Listeria with strong implications for the future development of vaccines. http://www.physorg.com/news174024956.html Biology Tue, 06 Oct 2009 05:16:31 EST news174024956 University of Central Florida Microbiology Professor Keith Ireton has uncovered a previously unknown mechanism that plays an important role in the spread of a deadly food-borne bacterium. http://www.physorg.com/news172768529.html Biology Mon, 21 Sep 2009 17:30:02 EST news172768529 By attaching light-emitting genes to infectious bacteria in an experimental system, researchers at University College, Cork, Ireland, have been able to track where in the body the bacteria go - giving an insight into the path of the infection process leading to the development of more targeted treatments. http://www.physorg.com/news171693172.html Biology Wed, 09 Sep 2009 05:37:15 EST news171693172 (PhysOrg.com) -- Scientists in Indiana are reporting development of a new biosensor for use in a faster, more sensitive test for detecting the deadliest strain of Listeria food poisoning bacteria. That microbe causes hundreds of deaths and thousands of hospitalizations each year in the United States, particularly among people with weakened immune systems. Their study appears in the current issue of ACS` Analytical Chemistry. http://www.physorg.com/news159701332.html Chemistry Thu, 23 Apr 2009 10:29:36 EST news159701332 When an infection attacks, the body's immune system sounds the alert, kills the invading germs and remembers the pathogen to protect against contracting the same type of infection again. Exactly how immunological memory develops is a mystery just beginning to be unveiled by Emma Teixeiro, PhD, in an article published in the Jan. 23 issue of the journal Science. http://www.physorg.com/news151858322.html Medicine & Health Thu, 22 Jan 2009 14:52:30 EST news151858322 A new report demonstrates how a sensitive imaging technique gives scientists the upper hand in seeking out bacteria in chronic infections. http://www.physorg.com/news149170837.html Medicine & Health Mon, 22 Dec 2008 12:20:37 EST news149170837 The food poisoning bacterium Listeria could survive on surfaces in meat processing factories if certain other bacteria are present, scientists heard today (Wednesday 10 September 2008) at the Society for General Microbiology's Autumn meeting being held this week at Trinity College, Dublin. http://www.physorg.com/news140242519.html Biology Wed, 10 Sep 2008 05:15:19 EST news140242519
