Clostridium difficile is a dangerous superbug. Infections with this bacterium can cause life-threatening diarrhea, and they are most likely to affect the elderly or people with health problems who spend a lot of time in hospitals (where C. difficile flourishes). The Centers for Disease Control a... Read More
A new cross-sectional study comparing the asthma and environmental profiles of children aged 7-14 years, from Amish households in Indiana, and Hutterite households in South Dakota found that:
1. Dust extracts from Amish households were found to have higher concentrations of endotoxins and alle... Read More
Insight into the biology of rhinovirus C from cryo-electron microscopy, and a novel antibiotic from a commensal bacterium that grows in the human nose, from the doctors of TWiM.
The TWiV team is together in New York City for a conversation with Nobel Laureate Harold Varmus about his remarkable career in science.
How do you identify an unknown microbe? If you’ve taken an introductory microbiology lab course in the past twenty years, chances are you were assigned an unknown bacterium that you had to identify through differential media and biochemical assays. Newer techniques like qPCR are being standardiz... Read More
In some individuals, an influenza A virus infection can cause asymptomatic Staphylococcus aureus (S. aureus) to travel to the lungs where it can trigger severe, sometimes deadly, secondary pneumonia. S. aureus is one of the most common causes of secondary bacterial pneumonia in cases of seasonal... Read More
A new study by researchers at Baylor College of Medicine found that, "babies born to mothers who consumed a high-fat diet during pregnancy had a gut microbiome that was distinctly different from the one in babies of mothers on a non-high-fat diet".
Noteably, researchers found that, "the micro... Read More
At St. Jude Children’s Research Hospital in Memphis, Tenn., scientist Stacey Schultz-Cherry has been studying the impact of obesity on influenza severity.
“We saw during the 2009 flu pandemic that there’s an epidemiological link between people getting severe flu and being obese,” says Schultz... Read More
The TWiP troika solve the case of the Female from the Bronx, and reveal how feeding on different plants affects mosquito capacity to transmit malaria.
Washington, DC – August 9, 2016 – For years, researchers have known that the bacteria Staphylococcus aureus (S. aureus) can trigger severe, sometimes deadly secondary bacterial pneumonia, in some people who are subsequently infected with influenza A virus, but scientists have not known exactly h...

Washington, DC – August 16, 2016 – A trio of researchers at the University of Texas Health Science Center, School of Public Health in Houston, have identified the location of the genes that control production of toxins that harm people infected by Clostridium difficile bacteria. The gene locus, ... Read More
Background: Acinetobacter baumannii is commonly resistant to nearly all antibiotics due to presence of antibiotic resistance genes and biofilm formation. In this study we determined the presence of certain antibiotic-resistance genes associated with biofilm production and the influen... Read More
Have you ever gone to the beach, ready for a day of sun and sand, only to find a warning sign? One of the most common reasons beaches close is due to the presence of coliform bacteria. These indicator bacteria, such as Escherichia coli, are used as markers for fecal waste, since their presence c... Read More
Washington, DC – August 2, 2016 – Adjuvants – ingredients added to vaccinations for influenza and other viruses to help boost their effectiveness – can increase a host’s immune response but not enough to protect the obese against the ill effects of the flu, according to a mouse study published t...

Washington, DC – August 8, 2016 – For the first time in Brazil, a particular antibiotic resistance mechanism conferring resistance to the important antibiotic, colistin, has been detected in a human. It was in a strain of Escherichia coli that was isolated from a diabetic patient’s foot infectio... Read More
Washington, DC – August 1, 2016 – Plasmids are pieces of independent DNA that often carry multiple antibiotic resistance genes. Plasmids can jump from one bacterium to another, spreading that resistance. A team of French investigators now shows that bacteria that acquire plasmids containing res... Read More
On this episode of Virus Watch we cover three Zika virus stories: the first human trial of a Zika virus vaccine, the first local transmission of infection in the United States, and whether the virus is a threat to participants in the 2016 Summer Olympic and Paralympic Games. Read More
Polio returns to Nigeria, Zika virus spreads in Miami, and virus infection of plants attracts bumblebees for pollination, from the virus gentlepeople at TWiV.
Copper is used in everything from automobiles to air conditioners, but it has one property that makes it especially attractive for medical uses: It kills bacteria.
A burgeoning opportunity for copper producers relies on a simple premise: that the base metal is good for your health.
Copper ... Read More
