A molecule impedes the destruction of the 'Brucella' bacteria
Research carried out with the participation of the University of Navarra has shown how a determinate molecule helps an important pathogen, Brucella abortus, escape destruction within the cells charged with eliminating infectious agents (macrophages). View News Article (2005-06-15)


Balancing male fertility and disease resistance
An international collaboration of researchers, headed by Dr. Shiping Wang (Huazhong Agricultural University, China) has discovered that a single gene in rice regulates both male fertility and pathogen resistance, providing an unexpected genetic link between reproductive success and the disease resistance. View News Article (2006-05-08)


Salmonella survives better in stomach due to altered DNA
Since 1995 there has been a considerable increase in the number of infections with a specific type of Salmonella bacteria transmitted via food. This type, Salmonella serovar Typhimurium DT104, is resistant to at least five different antibiotics. View News Article (2007-01-31)


Irish Potato Famine-Causing Pathogen Even More Virulent Now
The plant pathogen that caused the Irish potato famine in the 1840s lives on today with a different genetic blueprint and an even larger arsenal of weaponry to harm and kill plants. View News Article (2013-07-19)


Marine pathogens spread much faster than their terrestrial counterparts
It has become increasingly clear that pathogen epidemics are as significant a component of marine systems as they are in terrestrial systems. At an National Center for Ecological Analysis and Synthesis (NCEAS) working group on Diseases in the Ocean, McCallum, Harvell and Dobson collated data on epidemic spread from both terrestrial and marine environments. Their analysis, in a forthcoming issue... View News Article (2003-11-24)


How an aggressive fungal pathogen causes mold in fruits and vegetables
A research team led by a molecular plant pathologist at the University of California, Riverside has discovered the mechanism by which an aggressive fungal pathogen infects almost all fruits and vegetables. View News Article (2013-10-04)


Potato blight plight looks promising for food security
Over 160 years since potato blight wreaked havoc in Ireland and other northern European countries, scientists funded by the Biotechnology and Biological Sciences Research Council (BBSRC) finally have the blight-causing pathogen in their sights and are working to accelerate breeding of more durable, disease resistant potato varieties. View News Article (2009-08-10)


Serious setback in the long-term treatment of HIV infection
Structured therapeutic interruptions (STI), long hailed as a way of reducing the side effects of long-term AIDS treatment, has been shown to be ineffective, according to a collaborative study between Swiss and British researchers. Professor Rodney Phillips and colleagues at Oxford University's Peter Medawar Building for Pathogen Research and the Zoology Department collaborated with a Swiss... View News Article (2002-10-10)


Researcher discovers pathway plants use to fight back against pathogens
Plants are not only smart, but they also wage a good fight, according to a University of Missouri biochemist. Previous studies have shown that plants can sense attacks by pathogens and activate their defenses. View News Article (2008-04-01)


USDA-led consortium sequences genome of key wheat pathogen
A U.S. Department of Agriculture (USDA)-led consortium of scientists has fully sequenced the genome of the pathogen that causes the wheat disease known as septoria tritici blotch, which can cause significant yield losses. View News Article (2011-06-13)
