Latest Virulence Stories
“The emergence of novel pathogens poses a major public health threat causing widespread epidemics in susceptible populations.” This is the opening theme proposed by researchers who studied a deadly form of E. coli in hopes that it would prevent another public health outbreak in the future.
From tiny villages in developing nations to suburban kitchens in the United States, dangerous strains of E. coli bacteria sicken millions of people each year – and kill untold numbers of children.
The virulence of plant-borne diseases depends on not just the particular strain of a pathogen, but on where the pathogen has been before landing in its host, according to new research results.
(Santa Barbara, Calif.) –– A recent discovery of "hypervirulent" Salmonella bacteria has given UC Santa Barbara researchers Michael Mahan and Douglas Heithoff a means to potentially prevent food poisoning outbreaks from these particularly powerful strains.
New treatments that combat the growing problem of antibiotic resistance by disarming rather than killing bacteria may be on the horizon.
When battling a deadly parasite epidemic, less resistance can sometimes be better than more, a new study suggests.
When battling an epidemic of a deadly parasite, less resistance can sometimes be better than more, a new study suggests.
Researchers have found the subtle genetic differences that make one parasite far more virulent than its close relative.
Scientists from the Schepens Eye Research Institute, a subsidiary of Mass. Eye and Ear and affiliate of Harvard Medical School, have found for the first time that a bacterial pathogen can literally mow down protective molecules, known as mucins, on mucus membranes to enter and infect a part of the body.
Acinetobacter baumannii is a species of pathogenic bacteria that is resistant to most antibiotics. Some think the disease is killing tens of thousands of U.S. hospital patients each year due to its resistance to drug treatment. It can cause severe pneumonia and infections of the urinary tract, bloodstream, and other parts of the body. It forms opportunistic infections including reports of attacking wounded soldiers and is sometimes abbreviated as MDRAB. It is the most relevant human...
