Latest Virulence Stories
Salmonella enterica, one of the main causes of gastrointestinal infections, modulates its virulence gene expression, adapting it to each stage of the infection process, depending on the free iron concentration found in the intestinal epithelium of its host.
How exactly bacterial pathogens cause diseases in plants remains a mystery and continues to frustrate scientists working to solve this problem.
Recent research aboard the space shuttle is giving scientists a better understanding of how infectious disease occurs in space and could someday improve astronaut health and provide novel treatments for people on Earth.
Providing clues into why the severity of a common parasitic infection can vary greatly from person to person, a new Johns Hopkins study shows that each one of three strains of the cat-borne parasite Toxoplasma gondii sets off a unique reaction in the nerve cells it invades.
A new study into Staphylococcus aureus, the bacterium which is responsible for severe chronic infections worldwide, reveals how bacteria have developed a strategy of hiding within host cells to escape the immune system as well as many antibacterial treatments.
It's a common assumption that animal migration, like human travel across the globe, can transport pathogens long distances, in some cases increasing disease risks to humans.
About one-third of the human population is infected with a parasite called Toxoplasma gondii, but most of them don't know it.
Studying how bacteria incorporate foreign DNA from invading viruses into their own regulatory processes, Thomas Wood, professor in the Artie McFerrin Department of Chemical Engineering at Texas A&M University, is uncovering the secrets of one of nature's most primitive immune systems.
Researchers at the University of Exeter have developed a new approach to studying potentially deadly disease-causing bacteria which could help speed up the process of finding vaccines.
New clinical strains of cholera appear to have evolved a distinctly different mechanism to cause the same disease according to research published in the current issue of the online journal mBioÂ®.
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...
