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

Shown here is a picture of a hookworm egg found on a concentrate in an ova & parasite exam
Human hookworms include the nematode species, Ancylostoma duodenale and Necator americanus. These species have indistinguishable eggs and can only be distinguished by their larvae.
Infective larvae g... Read More
A little MRSA snowflake to get you in the holiday spirit. Oxacillin/Methicillin resistant Staph aureus streaked out on Spectra agar - incubated at 35C O2 for 24hrs. Follow me on instagram @stylish_streaking for more fun cultures and other images showing the beautiful side of infectious diseases!... Read More
Microphotograph showing scolex and hooklets of Echinococcus granulosus. Read More
Scanning electron micrograph of a murine macrophage infected with Francisella tularensis strain LVS. Macrophages were dry-fractured by touching the cell surface with cellophane tape after critical point drying to reveal intracellular bacteria. Bacteria (colorized in blue) are located either in t...

In memory of Eugéne Penard (1855-1954) we have created a website to show the variety and beauty of amoeboid organisms in light- and electron-microscopic images. Read More

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
A former student dropped by my lab this morning, and brought me a gift: a knit bacteriophage! Many times, as educators, we hear what we haven't done well, or could do better. Sometimes, like today, we get a priceless "thank you" from a former student. Read More
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
When you're hard drive fails, you order a new one online and then swap it out. Why can't we do that for biological parts as well? From DNA robots and "organs-on-a-chip" to nanobristles that grab-and-release drugs, this slideshow explores the two major goals of synthetic biology: to build new bio... Read More
You heard it here first: petri dishes are the new canvases.
When Tel Aviv based physicist and biologist Eshel Ben-Jacob discovered two new strains of bacteria, paenibacillus dendritiformis and the paenibacillus vortex, he also discovered an untapped art form. The bacteria swim outward into sp... 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
Streak plate of Streptococcus pyogenes (incubated @ 37 degrees C for 48 hrs) showing beta hemolysis, complete lysis of red blood cells, around the isolated colonies. Image taken using transmitted light. Read More
Some wild clones of social amoebas farm the bacteria they eat, but this is a losing strategy if nonfarming amoebas can steal the farmers’ crops. To make the strategy work, the farmers also carry bacteria that secrete chemicals that poison free riders. The work suggest farming is complex evolutio... Read More
We continue our series of images that have made a difference in microbiology. This one, published by John Cairns in 1963 has earned a most deserved place in textbooks and reviews. It shows a radioautograph of an intact E. coli chromosome in the act of replicating. From this image, Cairns conclud... Read More
Bacillus cereus, a food-borne pathogen, is capable to form biofilms. Biofilms are microbial communities that are controlled by a biological mechanism called quorum sensing. In this image, the B. cereus biofilm was viewed under microscope using LPO and grown in microtiter plate well for 48 hrs of... Read More
