New regulatory component in infectious bacterium helps explain ability to survive in human body

The discovery of a new regulatory component in an infectious bacterium could aid efforts to explain its ability to survive in the human body, report microbiologists at The University of Texas Health Science Center at Houston (UTHealth) and University of Maryland, College Park, in the journal Science.

University of Leicester research sniffs out smell of disease in feces

A fast-sensitive "electronic-nose" for sniffing the highly infectious bacteria C. diff, that causes diarrhoea, temperature and stomach cramps, has been developed by a team at the University of Leicester.

Scientists identify developmental on-off switch for Streptomyces

Scientists have identified the developmental on-off switch for Streptomyces, a group of soil microbes that produce more than two-thirds of the world's naturally derived antibiotic medicines.

Gene therapy may offer significant advantages in prevention of botulism exposure

The current method to treat acute toxin poisoning is to inject antibodies, commonly produced in animals, to neutralize the toxin. But this method has challenges ranging from safety to difficulties in developing, producing and maintaining the anti-serums in large quantities.

Researchers make surprising discoveries about the body's early responses to HIV infection

Researchers at UC Davis have made some surprising discoveries about the body's initial responses to HIV infection. Studying simian immunodeficiency virus (SIV), the team found that specialized cells in the intestine called Paneth cells are early responders to viral invasion and are the source of gut inflammation by producing a cytokine called interleukin-1 beta (IL-1β).

Yale University researchers identify bacterial culprits that drive IBD

Yale University researchers have identified a handful of bacterial culprits that may drive inflammatory bowel diseases (IBD) such as Crohn's disease and ulcerative colitis, using patients' own intestinal immune responses as a guide.

Contaminated blood cultures can serve as diagnostic predictor for more targeted antibiotics

Some 30 percent of all positive hospital blood culture samples are discarded every day because they're "contaminated" - they reflect the presence of skin germs instead of specific disease-causing bacteria.

Researchers reveal how Listeria is able to survive antibiotics

Listeria is a dreaded bacterium that can be found in both unprocessed and processed foods. Over the last few weeks, 28 persons in Denmark have been infected with Listeria from processed food, sold in supermarkets. 13 have died.
