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

Acholeplasma laidlawii

Acholeplasma laidlawii, light micrograph (approximately 400X) Unstained. Note colonial morphology and classical 'fried-egg' appearance after 4 days growth Read More

E.coli on MacConkey Agar (Mac)

Streak plate isolation of E. coli on MacConkey Agar grown for 24 hrs at 37 degrees. E. coli demonstrates strong lactose fermentation indicated by the bright pink halo, bile precipitant around the colonies, and pink colony growth. Read More

Exophiala jeanselme

Exophiala jeanselmei. Some conidiophores are very short lateral pegs on hyphae. LCB stain Read More

Acinetobacter baumannii

This SEM depicts a couple of clusters of aerobic Gram-negative, non-motile Acinetobacter baumannii bacteria as seen under a magnification of 12,739x.

Members of the genus Acinetobacter are nonmotile rods, 1-1.5µm in diameter, and 1.5-2.5µm in length, becoming spherical in shape while in their... Read More

Conidiophores in Neurospora crassa

This is an 3D image of conidiophores of the filamentous fungus Neurospora crassa. Conidiophores are hyphae which differentiate to produce asexual structures named spores or conidia. The image taken using a confocal microscope shows conidiophores stained with a fluorophore which stains components... Read More

Masterworks in Petri dishes

Einstein in E. coli, an apple tree grown from fungi and a fluorescent Mario are just some of the masterworks cast in agar jelly by creative microbiologists. Read More

Immunoelectrophoresis

Immunoelectrophoresis. Wells 1 and 2 rabbit serum, Wells 3 rabbit gammaglobulin, trough 1 and 3 antirabbit serum, trough 2 anti-gamma-globulin Read More

Bacteriophage

These bacteria-infecting viruses, phages for short, are the most abundant life-form on the planet, their number far exceeding that of stars in the universe. Trillions inhabit each of us.

ASM GM 2014 - Where Pathogens Can Linger on Airplanes

Many air travelers are concerned about the risks of catching a disease from other passengers given the long time spent in crowded air cabins. New research shows disease-causing bacteria can linger on surfaces commonly found in airplane cabins for days, even up to a week. Participants discuss ... Read More

World's Largest, Unique Virus Photographed for First Time

These images are amazing and beautiful.

From Wired - "A virus so large and strange that it’s redefined the very concept of a virus has been photographed for the first time. It’s even weirder than expected." Read More

Cartography of the Human Body

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

Caulobacter crescentus

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

Bacillus subtilis

Gram stain of B. subtilis showing characteristic G +streptobacillus morphology. Read More

Multidrug resistance Pseudomonas aeruginosa

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
