People infected with West Nile virus can show a wide range of disease. Some develop life-threatening brain infections. Others show no signs of infection at all. One reason for the different outcomes may lie in the community of microbes that populate their intestinal tracts. A study from Washington University School of Medicine in St. Louis […]
For patients with difficult-to-treat, drug-resistant infections, seeing an infectious diseases specialist can be a lifesaver. Such patients experienced significantly lower mortality rates when treated by physicians specializing in infectious diseases, according to a study at Washington University School of Medicine in St. Louis. Researchers found that infectious disease physicians helped reduce 30-day mortality rates by […]
Patients who developed infections that were resistant to antibiotics were much more likely to survive if doctors specializing in infectious disease were consulted on their cases, according to a study published today in Open Forum Infectious Diseases. “Having an infectious-disease specialist see you when you have one of these infections [was linked to] a 50 percent […]
Abstract Background Multidrug-resistant organism (MDRO) infections are associated with high mortality and readmission rates. Infectious diseases (ID) consultation improves clinical outcomes for drug-resistant Staphylococcus aureus bloodstream infections. Our goal was to determine the association between ID consultation and mortality following various MDRO infections. Methods This study was conducted with a retrospective cohort (January 1, 2006–October 1, 2015) […]
Despite public health campaigns aimed at reducing unnecessary prescriptions for antibiotics, the drugs continue to be prescribed at startlingly high rates in outpatient settings such as clinics and physician offices, according to a new study at Washington University School of Medicine in St. Louis.

The very rare animals that reproduce asexually — only about one in 1,000 of all living vertebrate species — are thought to be at an evolutionary disadvantage compared with their sexually reproduced counterparts. But that theory doesn’t hold true regarding the Amazon molly, an all-female fish species that has thrived for millennia in the fresh […]
The current influenza outbreak – the worst across the United States in nearly a decade – is worrisome but still far less dire than a pandemic flu, which could kill millions. Such pandemics are exceedingly difficult to predict, but new research at Washington University School of Medicine in St. Louis offers details about flu viruses […]
A new anti-cancer strategy wields light as a precision weapon. Unlike traditional light therapy — which is limited to the skin and areas accessible with an endoscope — this technique can target and attack cancer cells that have spread deep inside the body, according to researchers at Washington University School of Medicine in St. Louis. […]
Respiratory infections peak during the winter months, and most people recover within a few weeks. But for those with a rare genetic lung disease, the sniffling, coughing and congestion never end. The tiny hairlike structures called cilia that normally sweep mucus through the airways don’t work properly in people with what’s known as primary ciliary […]
More than 10,000 people in the United States are living with memory loss and other persistent neurological problems that occur after West Nile virus infects the brain. Now, a new study in mice suggests that such ongoing neurological deficits may be due to unresolved inflammation that hinders the brain’s ability to repair damaged neurons and […]

A new study now adds kidney disease to the list, according to researchers at Washington University School of Medicine in St. Louis and the Veterans Affairs (VA) St. Louis Health Care System. […]
Warfarin is a blood thinner that is commonly prescribed to patients to prevent life-threatening blood clots. Despite its longtime use, warfarin remains tricky to dose because a person’s genetic makeup influences how the drug is processed in the body. Too much warfarin can cause internal bleeding; too little warfarin fails to prevent blood clots. Now, […]
There’s good fat and bad fat in our bodies. The good fat helps burn calories, while the bad fat hoards calories, contributing to weight gain and obesity. Now, new research at Washington University School of Medicine in St. Louis has identified a way to convert bad, white fat into good, brown fat, at least in […]
Breast cancer that spreads often infiltrates bone, causing fractures and intense pain. In such cases, chemotherapy is ineffective because the environment of the bone protects the tumor, even as the drug has toxic side effects elsewhere in the body. Now, scientists at Washington University School of Medicine in St. Louis have developed a nanoparticle that […]
Brazil and other areas hardest hit by the Zika virus – which can cause babies to be born with abnormally small heads – are also home to dengue virus, which is spread by the same mosquito species.
A new study of children living in inner-city areas and at high risk of developing asthma suggests that exposure to certain pet and pest allergens in infancy lowers the risk of developing asthma by age 7. The research also provides evidence that the type of bacteria hitching a ride on the allergen particles is an […]
Researchers at Washington University School of Medicine in St. Louis are recruiting volunteers for a national study that is exploring whether strategies to improve cardiovascular health also reduce the risk of dementia in those at risk for Alzheimer’s disease.
