The lethality of avian influenza H5N1 infections in humans has been a matter of extensive debate. The >50% case fatality rate established by WHO is high, but the lethality of the virus might be lower if there are many infections accompanied by mild or no disease. One way to answer this question ... Read More
This lecture covers the biochemical basis of actin-based motility (focusing on the pathogen Listeria as a model system for this process), the biophysical mechanism of polymerization-based force generation, and an evolutionary perspective of cell shape in prokaryotes and eukaryotes. The first par... Read More
This episode: Bacteria may help prevent cavities!
The genomes of most higher organisms contain sequences from retroviral genomes called endogenous retroviruses (ERVs). These are DNA copies of retroviral RNAs that are integrated into the germ line DNA of the host, and passed from parent to offspring. In most species the infections that lead to g... Read More
A serological test is highly accurate at finding tuberculosis infection in elephants, and can determine such infection years before culture, according to a study in the August Clinical and Vaccine Immunology (click source to download the .pdf of the journal article). The issue is critical not on... Read More
This episode: A sample of bacteria in city air!
Some people think it would be great if scientists could wipe out all the microbial bugs! Should we do it, and why or why not?
We get a lot of requests to track down the nasty bugs that are making people sick. It's true that some microbes cause health problems such as strep throat, chi... Read More

Author Steven Johnson discusses The Ghost Map, his book about a cholera outbreak in 1854 London and the impact it had on science, cities and modern society. Read More
Some bacteria have hair- or whip-like appendages called flagella used to ‘swim’ around. Others produce thick coats of slime and ‘glide’ about. Some stick out thin, rigid spikes called fimbriae to help hold them to surfaces. Some contain little particles of minerals t... Read More

Thirty years ago this month I arrived in the Department of Microbiology at Columbia University’s College of Physicians and Surgeons (P&S) to start my own laboratory. Thirty is not only a multiple of ten (which we tend to celebrate), but also a long time to be at one place. It’s clearly time to r... Read More
On episode #107 of the podcast This Week in Virology, Vincent, Dickson, Alan, and Rich answer listener questions about poliovirus, social media, dengue, influenza, evolution, gel filtration, and much more. Read More
Chimpanzees from African sanctuaries carry drug-resistant, human-associated strains of the bacteria Staphlyococcus aureus, a pathogen that the infected chimpanzees could spread to endangered wild ape populations if they were reintroduced to their natural habitat, a new study shows.
The study ... Read More
At the Spring 2010 meeting of the Society for General Microbiology In Edinburgh Vincent Racaniello spoke about ‘Social Media in Microbiology Education and Research’. In his presentation he gives a comprehensive overview of how he uses these new communication tools to promote the science of virol... Read More
