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 more (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... view more (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 more (2007-01-31)

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... view more (2003-11-24)

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... view more (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 more (2008-04-01)

Nightshades: 'overflowing' with Phytophthora resistant genes?
The potato and other related varieties of the Solanum species contain scores or perhaps even hundreds of genes that can give the plant a degree of resistance to 'potato blight', a disease caused by Phytophthora infestans. This is one of the conclusions that came to light in Vivianne Vleeshouwers'... view more (2001-02-01)

Breakthrough in combating the growing risk from E.coli food poisoning
Certain pathogenic strains of the E. coli bacteria appear to harpoon themselves into intestine lining cells in order to colonise large sections of the gut, say scientists at Imperial College in London. The researchers, reporting the breakthrough in the new edition of BBSRC Business today, hope that... view more (2001-04-05)

Modeling pathogen responses
The search for a vaccination against HIV has been in progress since 1984, with very little success. Traditional methods used for identifying potential cellular targets can be very costly and time-consuming.   view more (2007-10-12)

Virginia Bioinformatics Institute launches microbial database
Researchers at the Virginia Bioinformatics Institute at Virginia Tech have launched a publicly-available microbial database to host a range of microbial genome sequences.   view more (2006-03-08)

Three human gene variants appear to influence tb susceptibility
Three variations of a human gene appear to impact human tuberculosis susceptibility, providing insight into why some patients infected with the Mycobacterium tuberculosis pathogen develop the full-blown disease and others do not.   view more (2006-06-23)

Study finds key distinction between outbreaks that die out and epidemics
In an important study forthcoming in the March 2006 issue of the American Naturalist, biologists from Yale University, University of Florida, and Dartmouth University explore the dynamics of pathogen survival and shed new light on a longstanding mystery: why some infectious diseases are limited to... view more (2006-02-22)

Increased environmental carbon levels - the good news!
Increasing carbon levels can be a good thing in some cases: scientists at the University of Durham propose that higher levels of inorganic carbon can have a positive influence on human health.   view more (2006-04-03)

Tree-Killing Fungus Officially Named by Scientists
The USDA Forest Service Southern Research Station (SRS) today announced that an SRS scientist and other researchers have officially named the fungus responsible for killing redbay and other trees in the coastal plains of northeastern Florida, Georgia, and South Carolina.   view more (2008-07-01)

Californians urged to help reduce spread of Sudden Oak Death
An update on the increased spread of Sudden Oak Death, a plant disease devastating many of California's coastal oak and tanoak trees, and information on what Californians can do to help reduce its spread will be presented during a news conference on plant diseases that are of importance to... view more (2007-07-16)

New method for testing condition of seeds
Wageningen UR develops method for testing condition of seeds Flow-cytometry, the technique for studying large numbers of individual cells in a fluid, can be combined with the use of special fluorescent colouring agents to form a valuable method of determining the health of seeds and seed... view more (2001-04-03)

Research promising for cystic fibrosis
New U of T research holds promise for developing innovative therapies against cystic fibrosis and may also serve as a model for future therapies against the HIV virus.   view more (2008-03-19)

Plant pathogen yields substance to fight neuroblastoma
Drug treatment of neuroblastoma, a tumor of the nervous system in children, poses major problems. Therefore, scientists at the German Cancer Research Center (Deutsches Krebsforschungszentrum, DKFZ) have been searching for substances that are suitable as a basis for developing better drugs. Now they... view more (2008-01-18)

Hawaii's anthurium growers cope with plant disease
A destructive pathogen is impacting Hawaii's production of anthuriums, a plant known for its heart-shaped flower and leaves.   view more (2006-03-02)

Scientists harvest answers from genome of grain fungus
Evil forces thrive in an unstable environment. At least, that's the picture being painted in the first waves of data being reaped from the genome sequence of the fungal plant pathogen, Fusarium graminearum.   view more (2007-09-07)

Pathogen virulence proteins suppress plant immunity
Researchers from the Virginia Bioinformatics Institute (VBI) at Virginia Tech and their colleagues have identified a key function of a large family of virulence proteins that play an important role in the production of infectious disease by the plant pathogen Phytophthora sojae.   view more (2008-04-22)

Halo Olight In The Bean Plant Not Detected
The oily stains accompanying the yellowish rings on the leaves and pods of bean plants are some of the symptoms of the disease known as "Halo blight" - highly important in temperate zones like Spain. The seeds are one of the most important sources of transmission of the pathogen, which... view more (2004-06-25)

DNA of good bacteria drives intestinal response to infection
A new study shows that the DNA of so-called "good bacteria" that normally live in the intestines may help defend the body against infection.   view more (2008-10-03)

New research approach required to combat more aggressive and adaptable Phytophthora
The potato late blight pathogen has become more aggressive since the arrival of a new type of Phytophthora in Europe circa 1976. Moreover, it is able to genetically adapt to new conditions more rapidly. As a consequence, research aimed at solving the problems caused by this disease must be on a... view more (2001-07-13)

Disease opened door to invading species in California
Plant and animal diseases can play a major and poorly appreciated role in allowing the invasion of exotic species, which in turn often threatens biodiversity, ecological function and the world economy, researchers say in a new report.   view more (2007-03-13)
