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
Acholeplasma laidlawii, light micrograph (approximately 400X) Unstained. Note colonial morphology and classical 'fried-egg' appearance after 4 days growth Read More
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
The production of Metallo-β-lactamase is one of the resistance mechanisms of Pseudomonas aeruginosa. Metallo-β- lactamases are members of Group B in the molecular classification of Ambler and are Clavulanic acid resistant enzymes which require divalent cations of zinc as co-factors for enzymat...

This is a joint project with water color artist Sarah Roberts to study the interaction of bacteria with traditional water colors. Many different types of bacteria have been assessed but only two so far, can be said to paint. When the white pigmented bacterium Proteus mirabilis, and the red Serra... Read More

Starch agar contains high molecular weight starch molecules (soluable starch). When Iodine is added it reacts with starch to produces a dark brown/purple color. A zone of clearing forms around organisms that produce the exoenzyme amylase after addition of iodine. This plate was incubated for ... Read More
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
Freelance photographer Nicola “Okin” Frioli has taken a collection of photographs/portraits of people wearing surgical masks in Mexico City. It's an interesting art project that looks at the impact swine flu has on the city's residents. Read More

With its abdomen engorged with a host blood meal, this image depicts a lateral, or side view of a female blacklegged, or deer tick, Ixodes scapularis.
The blacklegged or deer tick, Ixodes scapularis, transmits Lyme disease, a disease caused by a spiral shaped bacterial microbe, Borrelia burgdor... Read More
Two parallel rabbit testicular processes with attached Treponema pallidum. Note the ability of single treponemes to associate by the terminal ends to host cell surfaces and to bridge the two adjacent testicular cells Read More

Coccidioides immitis. Hyphae, arthrosporte and young spherule in lung. PSA stain (400X) Read More
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
This digitally-colorized scanning electron micrograph (SEM) of an untreated water specimen extracted from a wild stream mainly used to control flooding during inclement weather, revealed the presence of unidentified organisms, which included bacteria, protozoa, and algae. In this particular view... Read More
