Video Clips
Dr. Brett Finlay shows how bacteria can grow rapidly to incredible numbers, and also explains what limits this explosive growth.
Video Clips
Dr. Brett Finlay enlists a student volunteer to show the surprisingly high amount of bacteria found in his own mouth.
Video Clips
Dr. Finlay and a student volunteer show how Listeria infects a cell, using a marble and some yellow gelatin.
Video Clips
Dr. Finlay and another student volunteer illustrate how Salmonella infects a cell, using a marble, plastic wrap, and some yellow gelatin.
Video Clips
This microscope video shows how live Listeria move via actin filaments in an infected cell.
Video Clips
Salmonella are a common bacteria associated with food poisoning. Dr. Finlay shows live Salmonella under the microscope to demonstrate how far and fast they can move.
Video Clips
Penicillin, as shown in this video, causes the cell walls of bacteria to rupture.
Video Clips
Dr. Finlay and Dr. Richard Ganem use physical analogies to compare the size of bacteria and viruses relative to a standard mammalian cell.
Video Clips
Using a bagel, a syringe, and blue dye to illustrate how some virulent strains of bacteria inject virulence factors into a cell.
Apps
Learn about the science and techniques used to identify different types of bacteria based on their DNA sequences
Lectures
Bacteria are capable of communicating and coordinating their activities with a molecular signaling system called quorum sensing.
Lectures
The quorum sensing system is a target for a new class of drugs that interfere with virulence without killing bacteria.
Lectures
In this 13-minute Q&A session, Dr. Bonnie Bassler answers questions on quorum sensing and other topics related to bacteria.
Lectures
Microbes have been the dominant life form throughout Earth's history. Eukaryotes and animals evolved only after microbes evolved oxygen-generating photosynthesis.
Series
What medical secrets do venomous snails hold? How can listening in on bacterial conversations help develop new antibiotics? In four presentations, Dr. Bonnie L. Bassler and Dr. Baldomero M. Olivera reveal how a deeper understanding of nature and biodiversity informs their research into new...
Lectures
Dr. Brett Finlay explains why bacterial diseases continue to be a major health problem worldwide, causing a third of the world's deaths every year.
Lectures
Dr. Finlay showcases three types of bacteria to illustrate how molecular biology is allowing researchers to probe the molecular workings of bacterial infections.
Series
In four presentations, Donald E. Ganem, MD, and B. Brett Finlay, PhD, discuss the latest advances in understanding how pathogens invade the body and how this knowledge is leading to the development of new therapies. They also explain how new infectious diseases are recognized and how epidemics...
Animation
Quorum sensing regulates gene expression by a protein phosphorylation cascade that controls transcription.
Animation
Bacteria can transfer genetic material, and thus drug resistance, to other bacteria via conjugation.
Animation
Watch this animation to see the molecular tricks that an infectious strain of Escherichia coli uses to infect your gut.
