When infection with hepatitis C virus goes from acute to chronic, severe liver disease may occur which requires organ transplantation. Nearly 200 million people are chronically infected with HCV, necessitating approaches to preventing and treating infections. No HCV vaccine is available, and cur... Read More
A second virophage has been identified. The name does not signify a virus that infects another virus – it means virus eater.
The virologists who carried out the contentious experiments on influenza H5N1 transmission in ferrets have agreed to remove certain details from their manuscript, according to ScienceInsider. This is a bad day for virology, and for science in general. The decision by the NSABB sets a precedent f... Read More
Australian virologist Frank Fenner, MD was born in Ballarat, Victoria in 1914. He earned a Doctor of Medicine in 1942 at the University of Adelaide, and from 1940 – 1946 he worked on the malaria parasite in Egypt and Papua New Guinea as an officer in the Australian Army Medical Corps.

Enterococci had been generally regarded as benign commensals, a part of our healthy intestinal microbiota. They were even invited in, being used as probiotics. But then, in the late 1970s, the first multiple drug-resistant strains appeared, and vancomycin-resistant strains followed in 1981. In r... Read More
Yesterday the Chicago Tribune published my reaction to the four papers on the retrovirus XMRV published this week in the journal Retrovirology. I was quoted as saying ”These four papers are probably the beginning of the end of XMRV and CFS”. I wish to retract this statement and explain my reason... Read More
This is a great article by Carl Zimmer in the NY Times (@carlzimmer on Twitter) about the evolution process of viruses.
"Some viruses use DNA, like we do, to encode their genes. Others, like the influenza virus, use single-strand RNA. But viruses all have one thing in common, said Roland Wolk... Read More
Elio Schaechter of Small Things Considered has authored an interesting post today about the motility of bacteria, specifically Paenibacillus, although he does highlight several other strains that swarm, glide or twitch.
"Microbes get around. They can be carried by the wind, by insects, or by ... Read More
This past February I was interviewed by the Australian Broadcasting Company on the topic of the Fouchier and Kawaoka experiments on avian influenza virus H5N1. The video, Building the Perfect Bug, has been released by Journeyman Pictures and includes interviews with S.T. Lai, Laurie Garrett, Mic... Read More
The finding of viral nucleic acid sequences in illegally imported wildlife products has attracted the attention of the New York Times, which published an article entitled From the jungle to J.F.K., viruses cross borders in monkey meat. Read More
One hundred million years ago the earth’s climate was much warmer than today and vast inland seas stretched across entire continents. The land was dominated by charismatic megafauna that would one day serve as inspiration for Sir Arthur Conan Doyle’s novel The Lost World. This period is commonly... Read More

Human Lyme disease is caused by a number of related Borrelia burgdorferi sensu lato species. We report here the complete genome sequence of Borrelia sp. isolate SV1 from Finland. Read More
According to the New York Times (Why Science Majors Change Their Minds), the decline in the number of science majors in the United States has come about in part because the subject matter is too difficult. If this explanation is true, then we have not properly prepared these students in grades K... Read More
Merry Youle of Small Things Considered has authored a post that looks at Thiomargarita spp.
"Non-motile Thiomargarita was first discovered in 1999 off the Namibian coast, thus was named T. namibiensis. Its cells are large spheres, arranged in chains, each chain enclosed in a mucous sheath. Av... Read More
First, you may be asking yourself – Why viral bioinformatics? Good question! Although it’s true that much in the world of bioinformatics can be applied to all manner of protein and DNA sequences, there are a number of resources that are specific for viruses and there are a number of analyses tha...

I'm just writing to clarify my question about the production of the flu vaccine if one of the other seasonal strains was removed as there seemed to be a bit of confusion about the point of it.
As I understand it one of the biggest holdups in seas... Read More
