(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 Researchers have successfully applied a novel method of vaccine creation for Chikungunya virus (CHIKV) using a technique called large scale random codon re-encoding. Using this approach, a group from the UMR_D 190, Emerging viruses Department in Marseille, France in collaboration with the University of Sydney, Australia, demonstrated that the engineered viruses exhibit a stable phenotype with a significantly decreased viral fitness (i.e., replication capacity), making it a new vaccine candidate for this emerging viral disease. This new report publishes on February 21 in the Open Access journal, PLOS Pathogens. http://medicalxpress.com/news/2013-02-method-next-generation-live-attenuated-viral-vaccines.html Medical research Thu, 21 Feb 2013 17:00:01 EST news280685328 During the 1930s, dedicated sanitaria and invasive surgery were commonly prescribed for those with the infection - usually caused by Mycobacterium tuberculosis, which the editors describe as "the most successful human pathogen of all time." http://medicalxpress.com/news/2013-02-tb-infection-clock-1930s.html Diseases, Conditions, Syndromes Mon, 11 Feb 2013 18:30:01 EST news279822545 A collaboration between researchers at the School of Biochemistry and Immunology and the Department of Microbiology at Trinity College Dublin has identified a mechanism by which the bacterium Staphylococcus aureus (S. aureus) colonises our nasal passages. The study, recently published in the prestigious journal PLOS Pathogens, shows for the first time that a protein located on the bacterial surface called clumping factor B (ClfB) recognises a protein called loricrin that is a major component of the envelope of cells in the nose and skin. http://medicalxpress.com/news/2013-01-bacterium-role-mrsa-colonises-human.html Diseases, Conditions, Syndromes Mon, 28 Jan 2013 08:09:35 EST news278582968 A collaboration between researchers at the School of Biochemistry and Immunology and the Department of Microbiology at Trinity College Dublin has identified a mechanism by which the bacterium Staphylococcus aureus (S. aureus) colonizes our nasal passages. The study, published today in the Open Access journal PLOS Pathogens, shows for the first time that a protein located on the bacterial surface called clumping factor B (ClfB) has high affinity for the skin protein loricrin. http://medicalxpress.com/news/2012-12-staphylococcus-aureus-nose.html Diseases, Conditions, Syndromes Thu, 27 Dec 2012 17:00:01 EST news275848959 Researchers have successfully tested in monkeys a vaccine against Nipah virus, a human pathogen that emerged in 1998 during a large outbreak of infection and disease among pigs and pig farmers in Southeast Asia. This latest advance builds upon earlier work by the scientists, who found that the same vaccine can protect cats from Nipah virus and ferrets and horses from the closely related Hendra virus. http://medicalxpress.com/news/2012-08-vaccine-successfully-monkeys-nipah-virus.html Diseases, Conditions, Syndromes Wed, 08 Aug 2012 14:00:01 EST news263648470 Hepatitis G virus was identified in 1995. Some little research was carried out on the virus and the US Food and Drug Administration (FDA) declared it a non-harmful virus in 1997. Researchers in Saudi Arabia, writing in the International Journal of Immunological Studies present evidence to suggest that this may have been the wrong decision. They claim that transmission of the virus through donated blood that was not screened for the virus as well as infection through other routes has led to an increase in cirrhosis of the liver and liver cancer. http://medicalxpress.com/news/2011-08-virus-liver-cancer.html Diseases, Conditions, Syndromes Mon, 22 Aug 2011 10:03:50 EST news233226210
