sputum achieving score of 0 because of abundant squamous cells and absence of neutrophils - a mixed culture occurred with colonies resembling pseudomas aeruginosa, escheria coli and klebsiella or enterobacter Read More
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

A colorized scanning electron micrograph of Mycobaterium tuberculosis, the bacteria that cause TB.
Tuberculosis, commonly known as TB, is a contagious and an often severe airborne disease caused by a bacterial infection. TB typically affects the lungs, but it also may aff... Read More
Slime production by Staphylococcus epidermidis on Congo Red agar; demonstrated by black colored colonies. Slime production is one of the most important virulence factors produced by Coagulase negative Staphylococci.
The colonies of slime non-producing strains remain pink to red.

As researchers, sneakers on, trickled out of UC San Francisco’s Genentech Hall on a warm, windless evening this week, assorted persons with stylish glasses and prettier footwear made their way against the flow and into the building’s marble atrium.
The California College of the Arts and the ... Read More
This confocal micrograph shows the mumps virus protein (turquoise) in the endoplasmic reticulum of a cultured cell. This is a region of the cell that processes proteins. This particular protein is possibly involved in determining how effectively the virus can infect people. By looking at how it ... Read More
This swirling mass may look like some kind of LSD trip, but it's actually fractal artwork created using bacteria.
Produced by Eshel Ben-Jacob—a scientist-cum-artist at Tel Aviv University—the piece came about thanks to two strains of bacteria which grew together in interesting and weird ways.... 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
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
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

A sample of Proteus mirabilis was inoculated on to a TSA plate by taking a sterile swab and placing a drop in the center of the plate. The plate was then incubated at 37 degrees for 8 hrs. Swarming motility can be seen as a clear halo and finger like projections coming from and around the grow... Read More
