Virologia en Español

Tengo el gusto de anunciarles que mi curso de virologia esta ahora disponible en Español.

Este trabajo se realizó bajo la dirección de la Dra. Susana López, virologa del Departamento de Genética del Desarrollo y Fisiología Molecular del Instituto de Biotecnología de la Universidad Nacional A... Read More

Evidence-based antibiotic usage

New recommendation encourages physicians to prescribe _antibacterials_ instead of antibiotics for bacterial infections. This recommendation is based on compelling evidence that the word "antibiotic" confuses almost everyone, including some doctors. The confusion leads to strong patient demands... Read More

How I record my lectures

Each year as I teach my undergraduate virology course, I record each lecture and put them online where they are freely accessible. A student in my virology course approached me recently to thank me for making the lectures available online, and wondered why other professors did not so the same. T... Read More

Creative "Extra Credit" Projects in Microbiology!

In this blog entry, I explore how students can use their creativity to learn microbiology in innovative and often artistic ways. It makes learning more personal! Read More

Fouchier vs the Dutch government on influenza H5N1 research

Readers of this blog will remember the furor sparked by Fouchier’s experiments in 2011 in which he developed an avian influenza H5N1 isolate that could transmit among ferrets by aerosol. When Fouchier was ready to publish the results, the Dutch government required that Fouchier apply for an expo... Read More

Hepatitis B viruses in bats

Hepatitis B virus (HBV, illustrated) is a substantial human pathogen. WHO estimates that there are now 240,000,000 individuals chronically infected with HBV worldwide, of which 25% will die from chronic liver disease or hepatocellular carcinoma. The hepatitis B virus vaccine is highly effective ... Read More

Pandoravirus, bigger and unlike anything seen before

The discovery of the giant Mimivirus and Megavirus amazed virologists (and also many others). Their virions (750 nanometers) and DNA genomes (1,259,000 base pairs) were the biggest ever discovered, shattering the notions that viruses could not be seen with a light microscope, and that viral geno...

Why Sourdough Bread Resists Mold (Press Release)

Sourdough bread resists mold, unlike conventionally leavened bread. Now Michael Gaenzle and colleagues of the University of Alberta, Edmonton, show why. During sourdough production, bacteria convert the linoleic acid in bread flour to a compound that has powerful antifungal activity. The researc... Read More

Microbe/Mineral Affinities

This is a paper from the Geomicrobiology lab at the Jackson School of Geosciences at the University of Texas at Austin. It was recently published in a special issue of Geomicrobiology Journal focused on geomicrobiology of subsurface microorganisms in cave environments.

In this study we attemp... Read More

A system‐level model for the microbial regulatory genome

Microbes can tailor transcriptional responses to diverse environmental challenges despite having streamlined genomes and a limited number of regulators. We present data‐driven models that capture the dynamic interplay of the environment and genome‐encoded regulatory programs of two types of prok... Read More

Circovirus in Shanghai

Recently thousands of dead and decaying pigs were pulled from rivers in Shanghai and Jiaxing, China. Apparently farmers dumped the animals into the water after the pigs became ill, and porcine circovirus was subsequently detected in the in pig carcasses and in the water. Porcine circoviruses are...

Inefficient influenza H7N9 virus aerosol transmission among ferrets

There have been 131 confirmed human infections with avian influenza H7N9 virus in China, but so far there is little evidence for human to human transmission. Three out of four patients report exposure to animals, ‘mostly chickens‘, suggesting that most of the infections are zoonoses. Whether or ... Read More

End of moratorium on influenza H5N1 research

In early 2012 influenza virus researchers around the world decided to stop working on highly pathogenic avian influenza H5N1 virus. This decision came after work from the Fouchier and Kawaoka laboratories revealed the isolation of influenza H5N1 strains that can be passed among ferrets by aeroso... Read More

The Walking Dead offers teachable moment about antivirals vs antibacterials

If you teach students about viruses and bacteria, recent episodes of The Walking Dead have been using the term "antibiotic" to stand for antivirals. Since students are probably watching the show, it might be a good time to highlight the mistake. I summarized the issues at the associated URL (ht... Read More

The Virtual Museum of Bacteria

The Virtual Museum of Bacteria is a website that presents curated links about bacteria, embedded in informative articles. The website is up and running since 1998, making it one of the oldest websites on the internet. The texts are kept simple, though the collected links vary from simple to adva... Read More

"Microbe-Powered Jobs: How Microbiologists Can Help Build the Bioeconomy" Infographic

The American Academy of Microbiology has just released a new report, "Microbe-Powered Jobs: How Microbiologists Can Help Build the Bioeconomy," and along with it, an infographic, that summarizes the main points of the report. The full report can be found here: http://bit.ly/1lk346I, and a link t... Read More

Bovine TB and badgers - why it all matters

With the news of a trial badger cull in England as an attempt to reduce the levels of Mycobacterium bovis or bovine TB in cattle, this post reviews why it is so important to reduce the level of the organism in the cattle and badger populations. Read More

Reducing antibiotic requests from patients with viral infections

For anyone interested in Antibiotic Awareness Week, a big part of the story is that patients (or their parents) demand antibacterials even for viral infections. And doctors often comply, just to get rid of them (the patients, that is). This high-resolution PDF can be printed out for waiting ro... Read More
