microTalkInto the Matrix: Fungal Biofilms with David AndesCandida albicans is the most common fungal infection of humans. C. albicans can cause superficial infections like thrush or vaginitis when it overgrows within healthy individuals, but it causes much more serious disease when it infects immunocompromised individuals. C. albicans can form a matrix-encased biofilm on indwelling medical devices that serves as a source to seed systemic infections in patients. Dr. David Andes is a professor at the University of Wisconsin and also the chief of Division of Infectious Disease who studies fungal infections. Dr. Andes talks about the problem of fungal biofilms and antifungal...

C. trachomatis are obligate intracellular bacteria, which has made studying the genetics of virulence particularly difficult. Dr. Mary Weber is an assistant professor at the University of Iowa who studies C. trachomatis. Dr. Weber talks about some of the difficulties studying this unusual obligate intracellular bacterium, how recent advances are providing hope for new therapeutics and vaccines, why antibiotics are not sufficient...

These bacteria are normally found in the marine environment, but they can spread rapidly through human populations and cause large epidemics. V. cholerae are able to coordinate their activities by “talking” to each other through quorum sensing, and to eradicate competitors through a harpoon-like appendage that stabs and kills other bacteria. Dr. Brian Hammer is an associate professor at Georgia Institute of Technology who studies V. cholerae and its ability to coordinate activities with its friends and kill off...

She is now a faculty member at the University of Alaska-Anchorage. Her research focuses on determining the extent that host genes control host-microbe interactions, utilizing the stickleback fish. Dr. Milligan-Myhre talks about the difficulty of maintaining her Native Alaskan cultural identity during her time in the “lower 48” studying microbiology, why stickleback fish are a great model for understanding how the host shapes the microbiota, how “code switching” allows he...
