(Medical Xpress)—Virginia Tech scientists have provided new evidence that biofilms—bacteria that adhere to surfaces and build protective coatings—are at work in the survival of the human pathogen Salmonella. http://medicalxpress.com/news/2013-04-salmonella-resilient-thought.html Diseases, Conditions, Syndromes Wed, 10 Apr 2013 08:49:19 EST news284802552 (Medical Xpress)—Vaccines that employ weakened but live pathogens to trigger immune responses have inherent safety issues but Yale researchers have developed a new trick to circumvent the problem—using bacteria's own cellular mistakes to deliver a safe vaccine. http://medicalxpress.com/news/2013-03-bacteria-safer-vaccine.html Medical research Wed, 13 Mar 2013 07:50:01 EST news282379385 Add those cute little hedgehogs to the list of pets that can make you sick. http://medicalxpress.com/news/2013-01-hedgehog-prickly-pets-salmonella.html Diseases, Conditions, Syndromes Thu, 31 Jan 2013 13:40:01 EST news278860922 Australian researchers have discovered that vitamin B metabolites produced by Salmonella bacteria can activate the immune system, a finding that could lead to new treatments for gut and lung diseases. http://medicalxpress.com/news/2012-11-salmonella-immune-defence.html Immunology Thu, 29 Nov 2012 06:42:51 EST news273393758 (AP)—Smoked salmon tainted with salmonella bacteria has sickened hundreds of people in the Netherlands, sparking major recalls there and in the U.S., Dutch authorities said. http://medicalxpress.com/news/2012-10-salmon-blamed-salmonella-outbreak.html Diseases, Conditions, Syndromes Tue, 02 Oct 2012 12:22:59 EST news268399369 (Medical Xpress)—A new study out today reveals that the emergence and spread of a rapidly evolving invasive intestinal disease, that has a significant mortality rate (up to 45%) in infected people in sub-Saharan Africa, seems to have been potentiated by the HIV epidemic in Africa. http://medicalxpress.com/news/2012-09-invasive-non-typhoidal-salmonella-epidemic-sub-saharan.html Genetics Sun, 30 Sep 2012 13:00:05 EST news268208664 (AP)—The Food and Drug Administration says salmonella found at a cantaloupe farm in southwestern Indiana matches the "DNA fingerprint" of the salmonella responsible for a deadly outbreak that sickened people in 21 states. http://medicalxpress.com/news/2012-08-salmonella-ind-farm-outbreak-strain.html Diseases, Conditions, Syndromes Tue, 28 Aug 2012 18:30:16 EST news265397411 Bacteria that cause the main food-borne infections among people in the European Union commonly show resistance to widely-used antibiotics and antimicrobials, an EU report showed Wednesday. http://medicalxpress.com/news/2012-03-resistant-food-bacteria-strains-common.html Diseases, Conditions, Syndromes Wed, 14 Mar 2012 12:00:55 EST news250945242 Food-safety experts have long believed that Salmonella bacteria could only enter tomatoes through wounds in the stem or fruit — but a new University of Florida laboratory study shows it can also happen another way. http://medicalxpress.com/news/2011-11-lab-conditions-salmonella-tomato-fruits.html Diseases, Conditions, Syndromes Thu, 10 Nov 2011 07:24:50 EST news240132283 Wegmans Food Markets has recalled 5,000 pounds of pine nuts sold in the bulk foods department of its stores in New York, Pennsylvania, New Jersey, Virginia, and Maryland after salmonella sickened 42 people. http://medicalxpress.com/news/2011-10-wegmans-recalls-nuts-salmonella.html Diseases, Conditions, Syndromes Thu, 27 Oct 2011 11:12:38 EST news238932751 (Medical Xpress) -- During such mass food-poisoning outbreaks as the recent contamination of ground turkey, speedy identification of the bacteria involved can save lives and reduce illness. New research co-authored by a Cornell food scientist will accelerate the process of identifying strains of salmonella bacteria behind food poisonings -- and reduce the time it takes to track the culprit from farm to fork. http://medicalxpress.com/news/2011-08-bacteria-salmonella-outbreaks.html Diseases, Conditions, Syndromes Wed, 31 Aug 2011 07:19:56 EST news233993968 Salmonella is widely prevalent in the animal kingdom. The reason we do not suffer from severe intestinal infections very often is due to our body's defence system, which manages to digest invading bacteria. This is why, generally speaking, a healthy human being will only fall ill if he consumes more than 100.000 salmonella bacteria via a contaminated food source, such as eggs or meat. An international team of researchers, led by Prof. Ivan Dikic from the Goethe University in Frankfurt has now found out how body cells recognise salmonella and render it harmless. Understanding this process at a molecular level is crucial in identifying new targets for treatment. Tropical and sub-tropical countries in particular, where various sub-species of salmonella are common, are experiencing a rapid increase in resistance to antibiotics, with children at greatest risk. http://medicalxpress.com/news/2011-05-intestinal-cell-defense-mechanism-bacteria.html Medical research Fri, 27 May 2011 10:28:10 EST news225710864
