About

The purpose of this blog is to teach you about viruses and viral disease. This topic is not one that everyone understands, yet nearly everyone would like to. I was most disturbed when the Secretary of Health and Human Services, Tommy G. Thompson, referred to the anthrax bacillus as a virus. That incident crystallized in my mind the need to better educate the public about viruses.

I am your host at virology blog – Vincent Racaniello Ph.D., Professor of Microbiology & Immunology in the College of Physicians and Surgeons of Columbia University. Why am I qualified to teach you virology? I have done laboratory research on viruses since 1975, when I entered the Ph.D. program in Biomedical Sciences at Mt. Sinai School of Medicine of the City University of New York. My thesis research, in the laboratory of Dr. Peter Palese, was focussed on influenza viruses. That’s me in the black and white photo below, taken in 1977. Yes, I’ve changed.

Vincent Racaniello 1977

In 1979 I joined the laboratory of Dr. David Baltimore at Massachusetts Institute of Technology, where I did postdoctoral work on poliovirus. The moratorium on cloning full-length viral genomes had just been lifted, so I proceeded to make a DNA copy of poliovirus RNA, using the enzyme reverse transcriptase. I cloned this DNA into a bacterial plasmid and determined the nucleotide sequence of the poliovirus genome. In an exciting advance, I found that a DNA copy of poliovirus RNA is infectious when introduced into cells. This was the first demonstration of infectivity of a DNA copy of an animal RNA virus, and it permitted previously unthought of genetic manipulation of the viral genome. Today infectious DNA clones are used to study most viruses.

In 1982 I joined the faculty in the Department of Microbiology at Columbia University College of Physicians & Surgeons in New York City. There I established a laboratory to study viruses, and to train other scientists to become virologists. Over the years we have studied a variety of viruses including poliovirus, echovirus, enterovirus 70, rhinovirus, and hepatitis C virus. As principal investigator of my laboratory, I oversee the research that is carried out by Ph.D. students and postdoctoral fellows. I also teach virology to undergraduate students, as well as graduate, medical, dental, and nursing students.

Since I think about viruses every day, and I have always been interested in teaching others about viruses, this blog seemed to be an ideal forum to convey some of my knowledge on this topic.

After starting this blog, I became interested in using ‘new media’ (internet-based media) to disseminate information about viruses. I’ve summarized my use of this format in an article entitled “Social media and microbiology education“, which you can find at the open-access journal PLoS Pathogens. In addition to writing about viruses on virology blog, I also host and produce three podcasts: This Week in Virology, This Week in Parasitism, and This Week in Microbiology. I teach a virology course each spring at Columbia University, and I post videocasts of each lecture at the course website, at iTunes University, and at Coursera.

If you would like to learn about our work on viruses in more detail, please visit my website at Columbia University, or my Wikipedia page. You might also like to follow me on Twitter or Google+, where I often provide links to interesting stories about viruses. I have also written about my work on this site; links to some of these articles are provided below.

    As-salaam alaikum By the will of Allah I have immunity against many infectious diseases. I have immunity against Ebola. By the will of Allah checked by a psychiatrist is quite adequate. At the request of the Administration of the President of Russia 2 times went to a psychiatric hospital. And thank God for the testimony of hospitalization were found.

    .Bolnoy Disabled 2 groups from childhood on two internal incurable disease By the will of Allah 17 years doing sports outdoors. Moonlighting distributor of newspapers in Almetjevsk. Sick not diabetes mellitus of other types. I drink a lot of water. On the recommendation of Allah saw on the Internet. Judging by the Internet can drink up to 20 liters of water a day, if not to take medicine. But Allah Almighty allowed me to take medicine. And with the permission of Allah, offer to make a vaccine against Ebola on my blood serum. PS. Since 2006, although not sick with influenza had often had the flu. Enter at risk as a distributor of newspapers .With Almighty Allah I have strong immunitet.Bely house and CDC sent letters to clarify I propose to make a vaccine for antibodies in my blood, not of my bloodphone +79046762574

    Hey, can you help me? I need some information about ebola virus, his protein, mutations. Do you know anyone that could help me?

    I am a student from China. Last year, I saw a little deserted dog (immature) which was infected by the Canine Parvovirus (CPV). The veterinarian said that it was the dog’s fear of desertion which had caused the CPV to infect it. I thought the claim was too ridiculous. Dr. Vincent, I know you are not a veterinarian, but could you kindly help me to find the true cause of the CPV and how dogs can prevent from it?

    Dear Dr. Vincent
    I am a student from China. I am very interested in your virology passages although I cannot understand all of them. Last year, I have heard a virus called Canine Parvovirus (CPV) which does harm to dogs and sometimes causes dogs’ death. The vet said that when dogs got deserted, they were usually infected by the virus. However, I still do not understand how this virus infect dogs. Dr. Vincent, have you heard about this kind of virus? Could you kindly give me a detailed explain of CPV? Thanks a lot!
