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 immune system exercises constant vigilance to protect the body from external threats--including what we eat and drink. A careful balancing act plays out as digested food travels through the intestine. Immune cells must remain alert to protect against harmful pathogens like Salmonella, but th... Read More
Imagine taking an ocean-side vacation, with the sun, sand, and water lulling you to relaxed bliss. After day at the beach, you experience an intense bout of stomach cramps and – more delicately put – GI distress. A rare day off is ruined because of a bug you picked up. Next, imagine a situation ... Read More
New research demonstrates how climate change and the immune reaction of the infected individual can affect the long-term and seasonal dynamics of parasite infections. The study, led by Penn State University scientists, assessed the infection dynamics of two species of soil-transmitted parasites ... Read More
Washington, DC – April 19, 2016 – Cities have their own distinct microbial communities but these communities don’t vary much between offices located in the same city, according to a new study. The work, published this week in mSystems, an open access journal from the American Society for Microbi... Read More
Michael Diamond visits the TWiV studio to talk about chikungunya virus and his laboratory's work on a mouse model of Zika virus, including the recent finding of testicular damage caused by viral replication.

As we highlighted in our previous blog, antibiotic stewardship – the careful use of appropriate antibiotic administration – can have positive effects. A small change from a difference in clinical lab reporting led to less drug use, which led to fewer drug-resistant infections. When we think of a... Read More
Researchers from the Institut Pasteur, Inserm, CNRS and Paris Descartes - Sorbonne Paris Cité University recently published a large-scale study in Nature Genetics based on almost 7,000 strains of Listeria monocytogenes -- the bacterium responsible for human listeriosis, a severe foodborne infect...

DENVER (Feb. 3, 2016) - The first national survey of skin infections among high school athletes has found that wrestlers have the highest number of infections, with football players coming in a distant second, according to researchers at the University of Colorado Anschutz Medical Campus. Read More
Feeling a bit under the weather? There’s a decent chance you’re suffering from an infection with an enterovirus. Enteroviruses are a commonly encountered virus, especially in the summer and fall. They can cause a variety of symptoms, from cold-like symptoms such as runny nose or fever to more se... Read More
Some kids & I have been swabbing their classroom, and this colony caught my eye, or is it two colonies living in a mutualistic relationship. Perhaps this is commensalism as the red one seems to really like the yellow one. Or perhaps it is the same colony of microbes, somehow producing two differ... Read More
The human microbiome is the diverse population of microorganisms that live on and in the body. Many thrive on the skin and in the mouth, but the majority live in the intestines. Over the last decade or so, microbiologists have become increasingly aware of how a person's microbial mix likely play... Read More
Antibiotics have proven to be a valuable weapon in the fight against infectious bacteria. However, due to the excess use of antibiotics in conventional treatments, overtime antibiotics have become less effective. Read More
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
Whether you're in town for ASM Microbe 2016 and looking for something to do with friends or family, or you're local to the Boston-area, come out to our "Microbial Conversations" public science event at the MIT Museum! Join us for short, sharp conversations about a variety of topics in microbiolo... Read More
I have worked on polio virus in my laboratory at Columbia University for 35 years. When that virus is eradicated--perhaps in the next few years--we will have to destroy all of our virus stocks. When that happens, I can either go home, or find another virus.
When Zika virus stepped into the w... Read More
Near Kisameet Bay on the central coast of British Columbia sits a deposit of clay that covers 5 acres and spans a depth up to 42 feet in places. This vast smear formed 10,000 years ago as glacial melt filled a granite basin and fine minerals silted out.
The ancient clay likely holds secrets t... Read More
Bacterial infection takes hold in the body when a pathogenic microorganism delivers toxins to healthy cells. One way bacteria accomplish this is by releasing vesicles, which act as tiny envelopes transporting toxins and other virulence factors to host cells. These toxins allow the bacteria to "m...

Unknown organism seem after washing hands on a hand print grown on TSA. Larger organism (possible Bacillus spp) is circular, edges not smooth, mucoid with rhizoid like growth towards the edges. Second smaller organism is yellow, mucoid, and has something erupting from the center. Read More
Recently, one of the Journal of Bacteriology Classic Spotlight series highlighted the numerous studies on bacterial spores that have been published in the journal throughout the years. Bacterial endospores, the resilient and relatively quiescent bacterial structures first identified in the 1800s... Read More
