This episode: Fungi herd and raise bacteria for slaughter!
(13.2 MB, 14.4 minutes)
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
Merry Youle of Small Things Considered has a new post about the history of American chestnut blight and the scientific efforts to restock North America with these stately giants through the introduction of biological control agents or with more traditional plant breeding techniques.

How do one-celled parasites move from the salivary gland of a mosquito through a person's skin into red blood cells? What molecular mechanisms form the basis for this very important movement of the protozoa? A team of researchers headed by Dr. Friedrich Frischknecht, head of a research group at ... 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
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 recent paper published in PLoS One looks at the relationship between alcohol consumption and Anopheles gambiae (the primary African malaria vector).
Malaria and alcohol consumption both represent major public health problems. Alcohol consumption is rising in developing countrie... Read More
How can something too small to be seen with the naked eye be powerful enough to bring down something like the U.S. Government? It turns out that microbes, mostly invisible, have the extraordinary capacity to affect our lives – through outbreaks of disease and the spread of fear. Twice in hist... 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

Most fungi can best be described as grazers, but a few are active hunters.
El podcast del Microbio Nº188 and 189 describes the famous experiment about prebiotic synthesis of organic compounds and t... Read More

Fightbac.org, the website of the Partnership for Food Safety Education (PFSE), has created some fun resources around common home food safety myths for educators and organizations to distribute, and they are allowing groups to add their own logos to them. In addition to the educators kit and down... 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
This episode: Discovery of a bacterium infected by two distinct organisms at the same time!

Session topics include:
*Genomics and Molecular Biology
*Antibiotic Therapy and Resistance
*Plasmids and Horizontal Transfer
*Epidem... 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
