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 have found a candidate: HC-toxin, which is... 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)
Red alert! How disease disables tomato plant's 'intruder alarm'
How a bacterium overcomes a tomato plant's defences and causes disease, by sneakily disabling the plant's intruder detection systems, is revealed in new research out today (4 December) in Current Biology. view more (2008-12-05)
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 means the detection of this bacterium in seeds is... 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 larger scale and involve even greater cooperation... view more... (2001-07-13)
Study finds higher pathogen loads in collapsed honeybee colonies
Honeybees in colonies affected by colony collapse disorder (CCD) have higher levels of pathogens and are co-infected with a greater number of pathogens than their non-CCD counterparts, but no individual pathogen can be singled out as the cause of CCD. view more (2009-08-14)
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)
APIC launches first national C. difficile prevalence study
The Association for Professionals in Infection Control and Epidemiology (APIC) today announced a detailed strategy to combat Clostridium difficile-associated disease (CDAD). view more (2008-03-24)
Professors to develop hand-held pathogen testing device
Testing for deadly food, air and water pathogens may get a lot easier and cheaper thanks to the work of a Michigan State University researcher and his team. view more (2006-12-19)
Huge virulence gene superfamily responsible for devastating plant diseases
A research team from the Virginia Bioinformatics Institute at Virginia Tech has identified an enormous superfamily of pathogen genes involved in the infection of plants. view more (2008-04-03)
Scientists find a key to immune system's ability to remember
Its ability to accurately catalog and recall long past encounters with viruses, bacteria and other pathogens is why we only get the measles or chicken pox once, and is why exposure to deactivated virus particles in vaccines confers protection from disease. view more (2006-10-24)
Acinetobacter baumannii, the hospital opportunist
Acinetobacter baumannii is an opportunistic pathogen operating in hospitals creating serious infections such as pneumonia. It principally affects patients who have weakened health and this is why we call it opportunistic. Moreover, the mortality rate from these infections are usually high given, on the one hand, the weakness of the patient and, on... view more... (2004-01-13)
Using the genomic shortcut to predict bacterial behavior
How do you study a pathogen that can't survive outside its host's cells? In a new study published in the open access journal PLoS Biology, Hiroyuki Ogata and colleagues show that sequencing and analyzing the genome of the bacteria Rickettsia felis provide valuable insights into the biology and behavior of this intracellular pathogen. view more (2005-07-05)
Live From The Lymph Node
Scientists at the German Research Centre for Biotechnology (GBF) in Braunschweig have successfully filmed individual cells migrating within a functioning lymph node. "We are the first in Europe to have taken such pictures," explains GBF researcher Dr. Matthias Gunzer. The new findings gleaned from observing immune cells in action in a living... view more...

New method enables gene disruption in destructive fungal pathogen
Researchers at the Virginia Bioinformatics Institute (VBI) at Virginia Tech, Colorado State University, and Duke University Medical Center have developed a new method to determine gene function on a genome-wide scale in the fungal pathogen Alternaria brassicicola. view more (2006-02-03)
New wheat disease could spread faster than expected
Both plant and human diseases that can travel with the wind have the potential to spread far more rapidly than has been understood, according to a new study, in findings that pose serious concerns not only for some human diseases but also a new fungus that threatens global wheat production. view more (2009-03-26)
Ebola virus disarmed by excising a single gene
The deadly Ebola virus, an emerging public health concern in Africa and a potential biological weapon, ranks among the most feared of exotic pathogens. view more (2008-01-22)
