News: This Genetic Defect Could Be Why Typhoid Mary Never Got Typhoid Fever

Whether or not a microbe is successful at establishing an infection depends both on the microbe and the host. Scientists from Duke found that a single DNA change can allow Salmonella typhi, the bacteria that causes typhoid fever, to invade cells. That single genetic variation increased the amount of cholesterol on cell membranes that Salmonella and other bacteria use as a docking station to attach to a cell to invade it. They also found that common cholesterol-lowering drugs protected zebrafi...

News: Probiotics Could Cut Sepsis in Infants for Just $1 a Day

Bacteria, viruses and other germs sometimes set off the immune system to overreact, producing a severe condition called sepsis. Sepsis is so dangerous that it is the leading cause of death of children across the world, killing a million kids every year, mostly in developing countries. Probiotic bacteria might be able to prevent sepsis and infections, but no large research studies have been done to find out whether that actually works. Until now.

News: You Don't Need Antibiotics for Pink Eye

Crusty, itchy, red eyes? There is a decent chance you could have conjunctivitis, or pink eye, an infection of the thin lining around the eye and the eyelid, caused by bacteria, an allergen, virus, or even your contact lenses. Whatever the cause — you call up your doctor to get a prescription to clear it up, right? Not really.

News: Replacement Joints with Antibiotics on Board Mean Lower Chance of Infection & Fewer Surgeries

For about a million Americans each year, a joint replacement brings relief from pain and restored mobility. But, 5–10% of those people have to endure another surgery within seven years, and most of those are due to an infection in their new joint. If doctors could treat infections more effectively, patients could avoid a second surgery, more pain, and another rehabilitation.

News: How Calcium Sets Off a C Diff Infection

Unfortunately, the very places we go to receive health care put us at risk for becoming infected with superbugs, bacteria exposed to so many antibiotics that they have become immune to their effects. Clostridium difficile (C. diff) is one such bacteria. It causes inflammation of the colon and rampant diarrhea that can have life-threatening consequences. Part of its virulence lies in the tough spores formed by the bacteria. They are responsible for starting infections in the colon and for spre...

News: How Gut Bacteria Could Set Off the Immune System in Rheumatoid Arthritis

As if the swollen, painful joints of rheumatoid arthritis weren't enough, the disease is the result of our immune system turning against cells of our own body. Ever since this realization, scientists have worked to find the trigger that sets the immune system off. Scientists believe that gut bacteria may have a role in initiating the abnormal immune response. Now, a team of researchers from Boston has figured out how that might occur.

Tasty Testing: Artisanal Cheese Reveals Microbial Secrets of Deliciousness

Whether your palate runs to domestic or imported, a piece of cheese can be a real treat for the senses. Its smell, taste, and texture are all parts of its appeal. A big part of what makes that savory wonderfulness comes from the microbes in and on the cheese. Thanks to a team of researchers dedicated to studying those microbes, we have a better understanding of their importance to cheese and us.

News: HIV Prevention Ring Passes Safety Testing Clinical Trial

Young girls, especially those who live in areas where HIV is epidemic, like sub-Saharan Africa, are particularly vulnerable to becoming infected with HIV. A vaginal ring containing the antiviral agent dapivirine has been shown to decrease the chance of developing HIV-1 in adult women over 21 and now in the first step for use in adolescents, the ring has been shown to be safe and well-tolerated in that younger age group.
