Adventure Travel Guide to the Microbial World

We are a group of faculty and first year graduate students who are embarking on a travel expedition into the microbial world.  Check this site for a description of what we learn and see along the journey.   You can also follow us on Twitter!  @ClassMicro

Viruses can do that too?

Bacteriophages, or phages, are a type of virus that specifically target bacteria for resources and reproduction1. The diversity of phages in size, functional capability, and genetic information is exponentially increasing as more are discovered and characterized. In general, phage infect a specific species of bacteria. Almost all phages have similar structures, consisting of a capsid “head” that stores genetic information and a “tail” that is used to interact with a host. Like other viruses, phages do not have a nucleus.

Skin microbiota: Roles in barrier maintenance & repair

            In recent years, the human microbiome began to be considered one of the major organs of the human body; it is defined as the collection of all the microorganisms living in symbiosis with the body (Human Microbiome Project, NIH).

Alcanivorax, an efficient cleaner of our oceans

Our oceans are chock-full of microbes, from the clear blue waters to the darkest depths.  In fact, the reason ocean water is so clear in some areas is due to the nearly perfect utilization of nutrients in the water.  Even though many people might find the thought of bacteria disgusting, they are invaluable members of marine ecosystems.  Along with other microbial life, they are responsible for the majority of the nutrient cycling that keeps everythi

The Superpowers of P. luminescens

The richness of the bacterial world is truly astonishing. While it is impossible to know an exact number of bacterial species on our planet, some reports help us appreciate the scope of the bacterial diversity.

A Microbe You May Not Know

On this episode of the podcast “This Week in Microbiology” Vincent Racaniello, Elio Schaechter, Michele Swanson, and Michael Schmidt discussed the research paper from the National Institute of Allergy and Infectious Disease (NIAID) by Myles et al. titled “Therapeutic responses to Roseomonas mucosa in atopic dermatitis may involve lipid-mediated TNF-related epithelial repair” which discussed the skin microbiome and atopic dermatitis.

VI4 Seminar, 1/14/21, Dr. Carolyn Ibberson

            This week, I attended a seminar from the VI4 at Vanderbilt University Medical Center, which hosted Dr. Carolyn Ibberson from Georgia Institute of Technology. She is a current faculty candidate for Vanderbilt and her presentation was titled “Insights into S.

A look at disease vectors: The mosquito

Insects inhabit our world, acting as agricultural pollinators and pests, as well as vectors of diseases. As common disease vectors, mosquitoes have been identified as one of the deadliest organisms in the world [1]. In a recent lecture, Dr.
