Artist Sonja Bäumel explores the skin microbiome in her project Cartography of the Human Body. Bacteria isolated from Bäumel’s skin were characterized and grown individually, then used to reconstruct an artificial microbiome with many layers of differently-colored species. Giant petri dishes gre... Read More

Serratia marcesens is a Gram-negative, rod-shaped bacterium that is commonly found in soil, water, on plants and in animals and thrives in damp conditions. This organism is well known for its production of the blood red pigment, prodigiosin. Production of prodigiosin can be influenced by several... Read More
Strain: Pseudomonas aeruginosa PA14
Medium: M8 minimal medium agar plates
Incubation Conditions: 48 hours at 37°C
Pseudomonas aeruginosa is a gram-negative, rod-shaped and monoflagellated bacterium that has an incredible nutritional versatility. Swarming motility, a flagellum-dependent behavi... Read More
Pseudomonas aeruginosa is one of the most notorious organisms that have brought the therapeutic dilemmas to clinicians as well as challenge to microbiologist throughout the world. It carries gene of intrinsic resistance (AmpC cephalosporinase, the OprD outer membrane porin, and the multidrug ef... Read More
Unknown yeast isolated on TSA from a swab taken from the bottom of a shoe incubated at 25 degrees C. Yellow, mucoid, round colonies were seen after 2 weeks. This isolate grew equally well at 37 degree C with a growth time of ~ 1 week. 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
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
For those of us who are normal, non-scientist people, an image of a virus doesn't necessarily hold any meaning. Which floating orb is a healthy cell? And which one is the actual virus? The CGSociety recently invited artists to create renderings of the HIV virus in blood—and the winning images ar... Read More

The common waterborne bacterium Caulobacter crescentus reproduces asymmetrically. When a cell divides, one of its daughter cells is a free-swimming “swarmer,” powered by a hairlike flagellum. The other, “stalk” daughter cell is immobile, anchoring itself to a surface with one of nature’s stronge... Read More
The campaign is called "Kick Back Ebola." But the posters pack a punch.
Sierra Leone has reported over 700 suspected Ebola cases, more than any other country this year. To help stop the outbreak, health workers have put up Ebola awareness signs all over Sierra Leone's seaside capital of Freet... Read More
