This episode: Bacteria are important for a good immune response to unadjuvanted influenza vaccines!
(14.6 MB, 16 minutes)
Serratia marcescens can form brilliant red colonies on LB agar due to the synthesis of the secondary metabolite prodigiosin. In the Microbiology teaching lab, we had students create pigment mutants of S. marcescens and these lovely shades of pink and white were collected for analysis. Read More
Vincent, Alan, Rich and Kathy discuss the association of a virus with sea star melting disease, and the finding of a phycodnavirus in the oropharynx of humans with altered cognitive functions.
Vincent, Dickson, and Daniel explain how trypanolytic factor forms membrane channels to lyse trypanosomes, and present a new case study.
Vincent, Dickson, and Daniel reveal last week's case study and introduce a new one concerning a patient who traveled to Belize.

Methanotrophs (bacteria that use methane for their carbon and energy) secrete siderophore-like compounds that are usually used to chelate copper and make it more bioavailable, but ... Read More
This episode: Scientists engineered E. coli to seek and destroy pathogens!
(10 MB, 11 minutes)
A bacterium can sense pathogens in the body, swim toward them, and release a deadly biofilm-busting payload. This process is called pseudotaxis, and could be modified for many... Read More
