Experiments with the most dangerous human viruses, such as Ebola virus and Lassa virus, are carried out in biosafety level 4 (BSL-4) laboratories. Since visiting the Northeast Infectious Diseases Laboratory BSL-4 and releasing the documentary video Threading the NEIDL, I was given the opportunit... Read More
As the West African epidemic of Ebola virus grows, so does misinformation about the virus, particularly how it is transmitted from person to person. Ebola virus is transmitted from human to human by close contact with infected patients and virus-containing body fluids. It does not spread among h... Read More
This is fun, and although I'm sure someone will gripe about Dicksons enthusiastic response to the crayfish, it made my life easier. I think it's Paragonimus kellicoti. As for eating raw crayfish; how drunk... Read More
About eight percent of human DNA is viral – remnants of ancestral infections with retroviruses. These endogenous retroviral sequences do not produce infectious viruses, and most are considered to be junk DNA. But some of them provide important functions. The protein called syncytin, which is ess... Read More
Team of researchers guided by Dr.Sarita G Bhat had developed a novel plate based screening technique for DOPA/melanin producing bacteria.Screening was based upon the clear zone formation on a medium suplemented with L-tyrosine.This new approach can be utilized in faster and accurate screening of...

Sea stars are lovely marine invertebrates with a round central body connected to multiple radiating legs (photo credit). In the past year millions of sea stars in the west coast waters of North America have melted into piles of slime and ossicles. Sea star associated densovirus might be the caus... Read More

Read about Angelina Fanny Hesse, an unsung heroine of microbiology who helped make the isolation of bacteria possible in this Popular Science blog post by Christina Agapakis:
"In the earliest days of microbiology, scientists were stumped about how to isolate bacteria. That is, until the fami... Read More

I thought you and the rest of the TWiM/TWiP folks would be interested in the following paper: Transferred interbacterial antagonism genes augment eukaryotic innate immune function, published online in Nature this week... Read More
Jason Roberts, a virologist at the Victorian Infectious Disease Reference Laboratory in Melbourne, Australia, creates three-dimensional simulations of viruses showing how the molecules that make up the capsid and genome might move in very short periods of time. I visited Jason in his laboratory ... Read More
During the winter of 1962 in California, a new virus was isolated from the oropharynx of 4 children who had been hospitalized with respiratory disease that included pneumonia and bronchiolitis. On the basis of its physical, chemical, and biological properties, the virus was classified as an ente... Read More
Antigenic variation is a hallmark of influenza virus that allows the virus to evade host defenses. Consequently influenza vaccines need to be reformulated frequently to keep up with changing viruses. In contrast, antigenic variation is not a hallmark of poliovirus – the same poliovirus vaccines ... Read More
Many people have a new awareness of the disease known as amyotrophic lateral sclerosis, or ALS, thanks to the Ice Bucket Challenge initiated by the ALS Association. Fewer might know that retroviruses have been proposed to play a role in the development of the disease. Read More
The 1918 influenza pandemic was particularly lethal, not only for the very young and the very old (as observed for typical influenza), but unexpectedly also for young adults, 20 to 40 years of age (pictured). It has been suggested that the increased lethality in young adults occurred because the... Read More
Given the extent of the Ebola virus outbreak in West Africa, transport of an infected individual to the US was bound to happen. The case is an adult who had contact with an Ebola virus-infected woman in Liberia, then traveled to Dallas. He had no symptoms before arriving in the US and therefore ... Read More
Malaria: shaking chills & fever (followed by sweats, not specifically mentioned in this case), is a characteristic of malaria that is unforgettable once one has had it (I had malaria four times).
Thick blood smears is de rigueur.
