Contemporary human viruses most likely originated by cross-species transmission from non-human animals. Examples include HIV-1, which crossed from chimpanzees to humans, and SARS coronavirus, which originated in bats. Since the 1989 discovery of hepatitis C virus (classified as a hepacivirus in ...

Dear TWiM Team
I see that some action is now being taken in America against the non-therapeutic use of antibiotics as livestock growth promoters:
Hi Vincent and Dickson,
I want to correct a statement you made in the trypanosomes episode. Apolipoprotein L-I in human blood kills only the subspecies Trypanosoma brucei brucei, whereas the East African subspecies Trypanosoma brucei rhodesiense and the... Read More
The Small Things Considered blog has just started a three-part series on oomycetes, also known as water molds.
The first piece (published today) describes oomycete biology, the other two will focus on a particular oomycete: the late potato blight pathogen.
Here's a clip:
"As you know, ... Read More
The Institute of Medicine has been asked to make recommendations about how to protect healthcare workers against swine-origin H1N1 influenza. They have been hearing presentations concerning the effectiveness of facemasks in preventing respiratory infections. Read More
Some viruses that infect bacteria (bacteriophages) deliver their DNA into the host cell with an amazing injection machine. The tailed bacteriophages (such as T4, illustrated) store their DNA in a capsid attached to a long tail tube that is surrounded by a sheath. At the bottom of the tube is a b... Read More
This teleconference is sponsored by the American Society for Microbiology and will review the history and importance of methicillin-resistant Staphylococcus aureus (MRSA) with a primary focus on the emergence of community-associated MRSA (CA-MRSA). The phenotypic and molecular identification of ... Read More
Science writer Carl Zimmer writes a masterful blog piece tracing the history of the study of ecosystems, from lakes to the human microbiome. Just one interesting fact: In their lifetimes, individual humans will produce about five elephants worth of microbes. Read More
Does the same concern that you discussed with suppressed immunity after a transplant apply to folks who undergo chemotherapy for cancer? (re strongyloides)
Hi V... Read More
The Judges' Choice for The Scientist magazine's 2011 Labby Multimedia Awards is this cute video on how microbes are essential for snow formation.
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 salt-loving (halophilic) bacterium which can grow in medium containing arsenic instead of phosphorus has been selected from the microbial community of Mono Lake in California. Arsenic (As) is a chemical analog of phosphorus and is usually toxic because it can enter metabolic pathways in the pl... Read More
Are you, Alan Dove and Prof. Racaniello, saying you think Mikovits and/or others on the Lombardi paper lied about the results or blinding? I think circumspection is a natural human reaction to the allegations of theft that have been made against Dr. Mik... Read More
I've really enjoyed hearing about the paths you and your guests took to enter the fields of virology and parasitology.
I was wondering if Dr. Dove could talk for a few minutes about how and why he decided to transition into sci... 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
