We’ve previously covered the importance of diagnostics in disease control and treatment. This is vital to controlling disease progression and transmission, but epidemiology studies can’t always show how a disease progresses or transmits. This is where scientists need a well-characterized animal ... Read More

Antibiotic-resistant bacteria are on the rise, making it more and more difficult to treat infections. But research suggests that the best defense against harmful bugs could be a healthy population of “good” gut bacteria. Read More
If it looks like a duck and quacks like a duck, it’s likely a duck – so goes the saying that illustrates the simplest explanation is usually the right one. But what about duck decoys used in conjunction with bird calls? Misidentification can be a deadly error – and the same goes for microbes. Mi... Read More
Estrogen dramatically reduced the amount of flu virus that replicated in infected cells from women but not from men, a new study by researchers at the Johns Hopkins Bloomberg School of Public Health shows. Read More
Human well being often flourishes under conditions of cooperation with others and flounders during periods of external conflict and strife.
According to Athena Aktipis, a researcher at Arizona State University's Biodesign Institute, microbes within the body--collectively known as the microbi... Read More
Because of its safety, efficacy, and affordability, chloroquine remains the treatment of choice for all Plasmodium species, except in regions with chloroquine-resistant P. falciparum. Chloroquine-resistant protists are treated with combination therapy, which includes artemisinin-derived molecule... Read More
Scientists at the University of Massachusetts Medical School (UMMS) have performed the first CRISPR/Cas9 screen to discover human proteins that Zika virus needs for replication. This work, led by Abraham Brass, MD, PhD, assistant professor in microbiology & physiological systems, reveals new lea... Read More
Babies at risk of a serious lung infection could be helped by a therapy based on the body's natural immune defences. Read More
Washington, DC - May 18, 2016 - Personal hygiene products such as soaps and toothpastes that contain the antibiotic triclosan do not have a major influence on microbial communities or endocrine function, according to a small, randomized trial. The study findings were published online May 18th in... Read More

Your birth year predicts—to a certain extent—how likely you are to get seriously ill or die in an outbreak of an animal-origin influenza virus, new research suggests.
Until now, scientists thought that previous exposure to a flu virus conferred little or no immunological protection against ne... Read More
Mapping and identifying all the microbes across New York City is no small feat. Just ask Jane Carlton. About three years ago, Carlton, director of the Center for Genomics and Systems Biology, and professor of biology, at New York University and colleagues won an NYU grand challenge grant for the...

The study - from Lund University in Sweden and published in the journal Scientific Reports - investigates a skin bacterium called Propionibacterium acnes. Senior author Dr. Rolf Lood, from Lund's Department of Clinical Sciences, explains:
"The name originates from the fact that the bacterium ... Read More
Several papers published in Genome Announcements recently describe the sequences of new Zika virus isolates. Scientists have known the genomic sequence of at least one Zika virus isolate since 2007, but continue to publish newly isolated strains. What is the importance of these additional sequen...

SILVER SPRING, Md. - The Walter Reed Army Institute of Research (WRAIR) began vaccinations today in a Phase 1 clinical trial to evaluate the safety and immune response of a vaccine candidate to prevent Middle East Respiratory Syndrome (MERS). Read More
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
Virus Watch is a new weekly video series that explores the amazing world of viruses. This week: the latest research on Zika virus, including finding virus in Brazilian monkeys, dengue antibodies helping Zika virus infection, and brain organoids to study how Zika virus causes microcephaly. Read More
New research indicates that curcumin--a substance in turmeric that is best known as one of the main components of curry powder--may help fight drug-resistant tuberculosis. In Asia, turmeric is used to treat many health conditions and it has anti-inflammatory, antioxidant, and perhaps even antica... Read More
Washington, DC - August 26, 2016 - Several species of bacteria found in smokeless tobacco products have been associated with opportunistic infections, according to a paper published August 25 in Applied and Environmental Microbiology, a journal of the American Society for Microbiology. Read More
