This is a picture of a Gram stain of an anaerobic blood culture. This pleomorfic bacteria, were Gram negative filamentous bacilli with large round bodies. The identification by MALDI-TOF was Fusobacterium mortiferum. The patient has pancreatitis. I agree if you want to share this picture, since ... Read More
This is as portrait of the late Francis Crick created by my wife Dr. Jennifer Quinn using "paint" of luminous bacteria. Photobacterium leignothi was grown in LB amended to 20g/l NaCl for a few hours until visible luminescence was detected visually. The liquid culture was painted onto amended L... Read More
A Time Lord needs his TARDIS to embark on fantastic discoveries. These LB agar plates contain a colorless reagent called X-gal, which is the sugar galactose linked to a dark blue dye. Some microbes can synthesize an enzyme (β-galactosidase) that snips the X-gal in two, releasing the blue color a... Read More
Sammy Salmonella was created on a Muller Hinton Agar using three different isolates of Pseudomonas aeruginosa and Staphylococcus aureus for the outline. Pseudomonas aeruginosa is the only species of Pseudomonas that will produce pyocyanin, which is what creates Sammy’s green color. These bacte... Read More
Hi, I am Bibha Dahal, Graduate Research Assistant from South Dakota State University. This is a fungal colony that I grew in my lab on Malt Extract Agar for 3 days at 28°C that resembles an 'eye'. Read More
This picture depicts that microbes too can add colours to life. As the beginning of a New Year adds colour to life. This agar art shows how microbes like Serratia marcescens, Pseudomonas aeruginosa, Staphylococcus Citrus add to happiness of new year. Read More
This beach scene was created with various species of Vibrio bacteria collected from coastal Massachusetts. Members of this genus of bacteria are commonly found attached to marine crustaceans and some can be harmful to the host and humans alike, especially if ingested. This genus includes the spe...

Leaves of the European chestnut tree contain ingredients with the power to disarm dangerous staph bacteria without boosting its drug resistance, scientists have found. Read More
Yeast extract-mannitol agar (YMA), with the pH indicator bromothymol blue (BTB), is the medium used for rhizobia isolation and characterization.

The image shows an agar plate with bright shinny bright green colonies growing in a precised direction. this tells us that Life is beautiful, colorful and full of precision. Each person ought to direct the path he/she wants to take in life and make it shine out to brighten the surroundings. Read More
A cartoon drawing of a phage particle (loosely based on the E. coli bacteriophage T4) drawn with a yeast contaminant on an LB agar plate, incubated at room temperature for several days. Read More
Bacteriophages were named because it appeared that the bacteria were being eaten by something. Here is a healthy E. coli strain (MG1655) that was mixed with a suspension of P1 phages and poured onto an agar plate. As the lawn of cells grew and covered the whole surface, plaques can be seen where... Read More
Each Fall, I teach a freshman writing class about symbioses and parasitism. I was very lucky to get some pretty famous people to "Skype" or "Google Hang Out" in to visit my class. Last Fall, one of my "tele-speakers" was the fabulous science writer and very funny fellow Ed Yong. The students ... Read More
New Haven, Conn. -- Nearly one in four patients with chronic hepatitis C (HCV) are denied initial approval for a drug therapy that treats the most common strain of the infection, according to a Yale School of Medicine study. Read More
Did you know that the bright orange/pink colours on flamingos depended on the kind of food they ate?
Here, our white flamingo was created by 3 drops of different oils; olive oil, Tween 20 and Tween 80; in a little experiment to determine which would be the best oil for lipophilicity.
One d... Read More
This blog post describes a "video meeting" between Seth Bordenstein and my freshman writing class in the Fall of 2014. My freshman class revolved around ideas in symbioses and parasitism, so Seth's ideas regarding holobionts and the hologenome were particularly apt. Furthermore, last week Seth... Read More
