In a healthy adult human body, most internal organs such as the brain, spleen, liver, and heart are devoid of microorganisms because the immune system keeps them in check. After human host death, however, the immune system falters and microorganisms proliferate throughout the body beginning in ... Read More

Acid Fast stain done on a mix of Staphylococcus aureus and Mycobacterium smegmatis. The stain was done on a culture of M. smegmatis that was incubated on a TSA slant with 1ml TSB added at 37 degree's C for 4 days, S. aureus was incubated in TSB at 37 degree's C for 24 hrs. Several loops of eac... Read More
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

Host: Jeff Fox with special guest, Thijs Ettema.
Thijs Ettema of Uppsala University in Sweden talks with Jeff Fox about a deep-sea archaeon, named Lokiarchaeum for the underwater volcano between Greenland and Norway near where it was found, that might be related to the last common anc... Read More
