Virology Lectures 2020 #2: The Infectious Cycle

The complete course of events in a virus infected cell is known as the infectious cycle. We discuss the different parts of the infectious cycle and how to study them, including assay of infectious virus particles by plaque assay, multiplicity of infection, and the particle to pfu ratio. Physical methods for detecting viruses include hemagglutination, serological techniques, polymerase chain reaction, and high-throughput sequencing. We show how these methods were used to identify the new coronavirus that has emerged in China.

I can't thank you enough for making your lectures available for free. It really warms my heart to see people that love to share knowledge. Many blessings to you!!

This man is phenomenal and his lectures are great! I’m a retired physician and know a lot of research but I have learned so much from these talks! It is amazing that these are free to view. I applaud the professor.

Why has this only got 12k odd views! - All of humanity should be educating themselves on this stuff! - I'm just some random bank worker, but i have to say virus's are fascinating "things"

I've taken over 70+ college courses and Professor Racaniello, you've given some of the best lectures I've seen. I'm giddy with knowledge! Wonderful information! Thank you!

[robertoguzman]

These lectures are just..fantastic. I followed all of them since the first one. The patience, the clarity, the material ...it is so inspiring to learn more. This professor is amazing.

[jonroads]

Got to say, I'm loving this series, please keep doing them!

Going through all of the lectures and taking notes; I can't thank you enough for making these available Dr. Racaniello. I study Trypanosoma cruzi so virology isn't directly pertinent, but everything in biology is essentially related, so these lectures will undoubtedly aid in my research!

[ihungchou]

You really make the topic come alive, Dr Racaniello; I've never enjoyed a lecture on such a technical subject as much. Thanks for making your course available to all.

[louisejuster]

I worked as a front line health worker with a high respect for PPE. You are amazing to freely share your knowledge.

[fireflyrises]

Thank you for showing where you are referring to on the visual aid.

[rbkuwar]

I found every year you have been incorporating new information. Thanks for doing this. Love itI have been listening these lectures for a couple year.

[ngandam]

Thank you for making these lecture available to public. I realized how much I learn from your lecture than my previous class.

[Stafford]

I' really grateful to you for making your lectures free. If you don't mind a bit of feedback, You very often assume knowledge that the listener does not have.

thanks dr
I am from Libya

I am very happy to listen your interesting lecture
thank you very much

[ericdekemp]

Vincent, great course! I like also the evolutionary aspect from the geological perspective. We owe our existence as humans and all life forms to a likely proto-cellular viral precurser.

[pedroorpheus]

Absolutely amazing and fascinating. And only two episode in. Even someone who has only helped kids to a-level chem and bio and done pop sci reading can follow 90% of this with a couple of pauses to check things on Wiki. Thank you very much indeed.

[redataha]

Thanks Prof. Dr. Vincent for all your great effort to what you teach us all about virology

[walrus]

This series is really interesting because it follows allong with the outbreak of coronavirus 19 and the emerging information about it

[DrSanjeevPandey]

You have been extremely generous to share these videos with us....you are too good to listen to....I am also trying to learn and catch the way you teach...its amazing...

[roninroshi]

Absolutely wonderful...the super well presented information presented here with out charge give s a clear understanding of what these viruses are by a gifted professor!
Thank you so much 🙏
