Vincent, Dickson, and Daniel consider the delivery of anti-trypanosome nanobodies to the tsetse fly via a bacterial symbiont, and present a new case study.
What do you get when you kiss a Petri dish? Bacteria and yeast colonies that grow into a pretty collage composed of different colors and morphologies. This is an LB agar plate incubated at room temperature for several days. Read More

Many institutions, such as my own, only have one microbiology course. In this second "Mu-Tube" video, I ask my current junior and senior Microbiology students what *they* think first year students ought to know about #MattersMicrobial. I think their opinions are interesting, and will inform my... Read More
Photograph of 400X magnified image of biogas digestor sample. A strange spiraled type microbe seen (probably like left handed DNA helix). The microbe is shown with an arrow. Has anyone seen such microbial structure? Read More
