Physarum polycephalum

Physarum polycephalum, slime mold, grown in a large perti plate on moist paper towels using oatmeal as the food source. Culture was grown in the dark at room temperature. The paper towel was moistened every day with tap water. After 3 week’s the culture formed sporangia (fruiting bodies). Im... Read More

Octopic cultivation

Cute octopus-like device for anaerobic cultivation of cellulolytic bacteria aimed to replace O2 with argon. Situated at the Faculty of Biology, Moscow State University, Russia. Read More

Microbes in the Environment

Microbes are everywhere; they live in us and on us. They can't be seen with our naked eyes, thus we tent to neglect that they're there or even existed. Some microbes are harmful and some are not. However, we must learn to avoid contaminating sterile media and materials with these microbes. In th... Read More

Aggregates of symbiotic/ commensal spiroplasma-like organisms (SLOs) in the midgut

Spiroplasmas are bacteria in the Class Mollicutes that are frequently associated with insects and/or plants. This confocal laser scanning micrographs show aggregates of symbiotic/ commensal spiroplasma-like organisms (SLOs) in the midgut (mg) and filter chamber (fc) of a leafhopper, Dalbulus mai...

New drugs for bad bugs

Washington University in St Louis chemist Timothy Wencewicz says we’ll stay ahead of antibiotic resistance only if we find drugs with new scaffolds, or core chemical structures. One promising candidate, an antibiotic made by a bacterium than infects plants, caught his attention because it contai... Read More

Pseudomonas paints a picture!

A student and I painted with bacteria and this is what happened! We used a method similar to that used by artist Sarah Roberts (UK) and microbiologist Simon Park.

Motility agar plates were prepared and painted with watercolor paint before inoculation with P. aeruginosa. After 7 days at room t... Read More

Ice Nucleation Bacteria, Twitter, and Me!

In this post from my microbiology/education blog, I discuss a post on Boing Boing recently that used a video I had made of ice nucleation bacteria. Ice nucleation bacteria are very interesting of course, and I link to the Boing Boing post. In addition, I provide an additional video of students... Read More

S. aureus on MSA Plate

For my medical microbiology course at Kutztown University of Pennsylvania we were asked to take a sample from our nose. Using a sterile cotton swab, a sample was taken from a nostril and then spread onto the Mannitol Salt Agar plate supplied. The plate was incubated at 37 degrees Celsius, then e... Read More

On a Cellular Level, We Are ALL Overachievers!

In this blog post, I show a science-cartoon by the great "Beatrice the Biologist" that illustrates an important point in my freshman introductory cell and molecular biology course: no matter how tired we might be, we are incredibly busy on a cellular level! Beatrice is a fine artist who underst... Read More

Sweet Valentine

Four intracellular Toxoplasma gondii parasites are shown undergoing cellular division by an internal budding process known as endodyogeny. Staining with a T. gondii surface antigen provided heart-shaped images (shot on Valentine’s Day). The definitive host of these parasites is the cat, but they... Read More

Microbe vs. Mineral - A Life and Death Struggle in the Desert

Although the bursts of rainbow colors in this photograph are mesmerizing, microbes fight for their lives in the background. Chemist Michael P. Zach of the University of Wisconsin-Stevens Point, snapped this image of a salt sample he collected in a hot, arid valley near Death Valley National Park... Read More

You'll Want To Wash Your Hands Immediately After Reading This (Infographic)

Germaphobes, maybe you're on to something.

Sickness-causing bacteria and viruses can lurk on surfaces long after they're expelled in an infected person's sneeze or snot. Some can even stay on a surface for months, given the right conditions. While the ability of these microorganisms to actual... Read More

Using Wordcloud-Reponses to Discover How Students Perceive Concepts in the Classroom

In this blog, I share some "first word that comes to mind" responses of my freshman biology class to the words "germ," "bacteria," "cell," and "DNA." The way that we perceive an idea or concept definitely impacts our relationship with it. Thus, finding out what students think, coming into our ... Read More

Creative "Extra Credit" Projects in Microbiology!
