In this first lecture of my 2016 Columbia University virology course, we explore the definitiions of viruses, their discovery and properties, and my goals for this course.
Last year someone asked for HD video - so this year, the videos are all HD.

The 1:1 ratio of human to bacterial cells came from accounting for red blood cells, which make up a staggeringly large number of cells. If you discount the RBCs, it goes back to 10:1. So, either ratio is correct, they are different only in the details. TWIV is great, by the way!

Hey Prof Racaniello. I started at Royal Holloway in the UK intentionally to study viruses - only to find that the only professor that interviewed me and was teaching the course had resigned over the summer before I arrived - so I never got to study my subject of choice. That was many many years ago and I'm glad for the internet and for you making your lectures public! Thank you. I hope you don't mind some critical feedback (a request in fact)... Whilst watching, it is sometimes difficult to follow you, as this is obviously your ppt presentation upload - but it misses all the parts where you are pointing at the screen etc. For example, one slide shows the scale of things down to the carbon atom and although the atom was labelled and so was easy to pick out, the others you mentioned including ribosomes etc. were not. Would it be possible for you to either have your lectures recorded 'live' by camera (or for you to edit your ppt uploads so we can see which part of a slide you're discussing) for future lectures perhaps? Either way, thank you for allowing us non-enrolled students the opportunity to continue to study :) PS - I found your personal views on 'alive or not' very useful - I have just had exactly the same discussion with my own students and can now provide them with another suggestion!

great interesting video though, I had to take a basic virology class for my botany degree, I have chemistry degrees as well and work on developing pesticides with a focus on mammals and some are working on viruses that would affect strictly affect rodents, rabbits and the such what do you think of that ? I've developed a couple based on lysergic acid basically and also synthetic cannabinoids which are in synthetic Marijuana products. Basically they confuse the animal enough to lose their way back to their nest/hole or forget where they got the food from, that or they trip out really hard and just hit their flight instinct and scare them into eating it again

Q1: When I search for bacteriophage images on the web I only find images of the T4 type, the syringe looking virus. Are there any other shape of bacteriophages? Are bacteriophages as selective as mammal viruses? I have never seen a mammal virus of the "syringe" type. Are there any? Is it because of the difference in cell membrane? Are all "syringe" type bacteriophages?

Q2: At the 6:15 slide you show that there are about 100 viruses particles/bacterium in sea water. That surprises me. I thought that the probability of a given virus particle finding its target organism was very very small. So unless they have a long viable lifetime (compared to its target) or that the fraction of parasitized bacteria the virus need to not going extinct is very small there should be a lot more virus particles/bacterium. Something like 10**6/1 or 10**7/1. I think of it as the situation of the number of pollen particles in the air per flower target.

Thank you for TWiV and for this course, Prof. Racaniello. I have a question about something you mentioned in this lecture. One of the very memorable TWiV episodes was the first time you all hosted Carolyn Coyne. I remember her conclusion that a surprising number of viruses cannot infect the placenta; I'm thinking about this issue a lot in the wake of the Zika virus reports on the presence of viral RNA in the amniotic fluid. In lecture, you mention that newborns' guts have a virome (amazing!) because the amniotic fluid of a mother is full of viruses. I guess I'm surprised. How'd all those viruses get in? Many thanks!

Well, if viruses can survive long-term on each finger, maybe hand washing doesn't do very much. I guess its just a numbers game, but maybe it stands closer inspection, what's the deal with hand washing.
