So far in this series I’ve written a good deal about our work on Zika virus, but I have said little about the people who are doing the science.
My lab at Columbia University Medical Center is very small, consisting of three people—Amy Rosenfeld, Audrey Warren, and me. Let me tell you about ... Read More
From ASV 2016 at Virginia Tech, Vincent, Rich and Kathy speak with Stephen Russell about his career and his work on oncolytic virotherapy - using viruses to treat cancers.

Vaccination with the anthrax capsule--a naturally occurring component of the bacterium that causes the disease--completely protected monkeys from lethal anthrax infection, according to a study published online this week in the journal VACCINE. These results indicate that anthrax capsule is a hig... Read More
Just like you and me, bacteria have ‘favorite’ foods – though in the case of bacteria, 'favorite' translates to those which are energetically favorable or most accessible. Different bacteria have different preferences, based on their environments and the neighboring microbes that compete for or ... Read More
By watching brightly glowing HIV-infected immune cells move within mice, researchers at the Icahn School of Medicine at Mount Sinai have shown how infected immune cells latch onto an uninfected sister cell to directly transmit newly minted viral particles. These interactions allow HIV to spread ... 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
Microbiome research has revealed that there are good guy and bad guy bacteria living together in complex communities on our skin, in our mouths, throughout our guts and pretty much everywhere in between. But what do you call a good guy bacterium that is aiding and abetting a disease culprit?

As part of its Microbiology of the Built Environment initiative, the Alfred P. Sloan Foundation started funding projects a few years ago that touched on the interaction of microbiology with architecture, buildings or, in the case of Curtis Huttenhower, PhD, an associate professor of computationa...

Researchers have discovered how the bacteria Group B streptococcus (GBS) avoids detection by the immune system during pregnancy. The findings, reported in the journal mBio, could lead to the development of new drugs and strategies for treating GBS infection, which is a leading cause of neonatal ... Read More
For years, researchers have struggled to get a handle on Group B streptococcus (GBS), in the hopes of improving neonatal outcomes. GBS are a bacteria commonly found in the vagina, rectum, and urinary tract of women. In healthy women, the bacteria are commensal, simply living without causing dise... Read More
Washington, D.C.—June 28, 2016—Researchers determined that two bacterial species commonly found in the human mouth and in abscesses, cooperate to make the pathogenic bacterium, Aggregatibacter actinomycetemcomitans, more infectious. Key to the cooperation is that the harmless partner provides th... Read More
Cold viruses cause us irritation by penetrating into our cells and transporting their RNA into the cytoplasma of the infected cells. This is the only way they can multiply. The details of how the transfer of the RNA from within the virus occurs are difficult to study. However, a new method has b... Read More
Alzheimer’s disease (AD) is an age-related neurodegenerative disease that is characterized by a progressive loss of memory associated with other cognitive sphere deficits interfering with social and occupational functioning. Read More
