The risk of being infected with human immunodeficiency virus type 1 (HIV-1) is substantially enhanced in individuals with other sexually transmitted diseases. For example, infection with herpes simplex virus type 2 (HSV-2) increases the risk ratio of acquiring HIV from 2 to 4. Explanations for t... Read More
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
Viruses are obligate intracellular parasites, which means that they must enter a cell to reproduce. As virions are too large to diffuse passively across the plasma membrane, cellular pathways for uptake of extracellular materials provide entry routes. The first step in entry is adherence of viru...

Dear Vincent and Dickson,
I just returned from the annual meeting of the International Society of Travel Medicine (ISTM) where I enjoyed many fantastic lectures and caught more Cutthroat Trout fly fishing the upper Snake River during one ev... Read More
The Twivsters discuss how reverse transcriptase encoded in the human genome might produce DNA copies of RNA viruses in infected cells.
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

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

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...

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
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

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
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
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...
