Virology - Biology W3310

Spring 2012

This is a virology course offered each year in the spring semester. All course materials for the 2011 session are archived elsewhere.
 
Prerequisite: Two semesters of a rigorous, molecularly-oriented Introductory Biology course (such as C2005), or the Instructor's permission (vrr1@columbia.edu).
 
Course Name: Virology
Sessions: M, W 4:10 - 5:25 PM
Start date: Wednesday, January 18, 2012
Points: 3
Location: Hamilton Hall 517
Course #: Biology W3310.001
Instructors: Prof. V. Racaniello, Prof. S. Silverstein
 
Description
The basic thesis of the course is that all viruses adopt a common strategy. The strategy is simple:
1. Viral genomes are contained in metastable particles.
2. Genomes encode gene products that promote an infectious cycle (mechanisms for genomes to enter cells, replicate, and exit in particles).
3. Infection patterns range from benign to lethal; infections can overcome or co-exist with host defenses.

Despite the apparent simplicity, the tactics evolved by particular virus families to survive and prosper are remarkable. This rich set of solutions to common problems in host/parasite interactions provides significant insight and powerful research tools. Virology has enabled a more detailed understanding of the structure and function of molecules, cells and organisms and has provided fundamental understanding of disease and virus evolution.

The course will emphasize the common reactions that must be completed by all viruses for successful reproduction within a host cell and survival and spread within a host population. The molecular basis of alternative reproductive cycles, the interactions of viruses with host organisms, and how these lead to disease are presented with examples drawn from a set of representative animal and human viruses, although selected bacterial viruses will be discussed.
 
Textbook
The recommended textbook is Principles of Virology. Vol I: Molecular Biology, Vol. II: Pathogenesis and Control (S.J. Flint et al., Third Edition, ASM Press 2009).
 
Other course resources
1. Students are expected to read Prof. Racaniello's virology blog which will contain information relevant to the course.
 
2. Students are expected to listen to the weekly podcast "This Week in Virology", produced by Prof. Racaniello, for additional material about viruses relevant to the course. You can subscribe to TWiV at iTunes or at the Zune Marketplace.
 
3. Lecture slides (pdf) will be posted at Courseworks and at this website before each class.
 
4. Videocasts of all lectures (slides plus audio) will be posted at Courseworks, at this website, and at iTunes University.
