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
We can see different biofilms types in liquid medium. In the same order than the picture: Methylobacterium variabile Type Strain / Methylobacterium aquaticum NO00 / Methylobacterium aquaticum NO42 / Methylobacterium aquaticum Type Strain / negative control Read More
Organism seen on handprint, presumably Bacillus sp. Organism grew out from the center with rhizoid growth, lobate edges, tan coloration, glossy throughout the colony, 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
This tree is made up of Streptococus pneumoniae (as the leaves)and Candida albicans (as the trunk),cultured on a chocolate agar incubated 24hours under 5% CO2 condition.
S.pneumoniae is a alpha hemolytic organism producing green colour colonies while C.albicans produce 'feet'around the margin o... Read More
Streptococcus pneumoniae cells are Gram-positive, lancet-shaped cocci. Usually, they are seen as pairs of cocci, but they may also occur singly and in short chains. In this photo a mucoid strain on blood agar showing alpha hemolysis (green zone surrounding colonies). Note the zone of inhibition ... Read More
A simple stain done on a stock culture of Aquaspirillum serpens to look at cell shape. This culture was grown in TSB at room temperature, ~21 degrees C, for several months. Aquaspirillum is a slow grower normally found in pond water. A characteristic spiral rod can be seen in the center of ... Read More
Image of E.Coli growth in Macconkey agar in helping hands community hospital, chabahil Kathmandu Nepal. E.coli growth was observed in 24 hours of incubation by Mr.sunil pandey intern student of medical Microbiology from Nobel College,Pokhara University Nepal. Read More
Serratia marcescens, Chromobacterium violeceum and Pseudomonas aeruginosa - what a romantic combination on Mueller Hinton II agar. All 3 organisms exhibit different pigment, Red, Purple and Green respectively on MHII agar, makes our daily routine of interpreting disk diffusion more interesting. Read More
Helicobacter is a Gram-negative rod with a helical shape on gram stain. The most known strain is H. pylori, which causes ulcers and chronic gastritis and is said to affect up to 50% of the human population. This particular strain, Helicobacter fennelliae is most commonly found in the feces an... Read More
I am sunil pandey from kathmandu Nepal, studying B.Sc in medical microbiology at nobel college. this is AST disc in MHA from blood sample, shows the clear zone of inhibition(Kirby -Bauer disc diffusion Method). I have done this experiment as part of my study "susceptibility of antibiotics in ba... 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
A little MRSA snowflake to get you in the holiday spirit. Oxacillin/Methicillin resistant Staph aureus streaked out on Spectra agar - incubated at 35C O2 for 24hrs. Follow me on instagram @stylish_streaking for more fun cultures and other images showing the beautiful side of infectious diseases!... 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
Our sensitivity instruments rarely ever go down, but when they do our lab uses Kirby-Bauer testing to perform antimicrobial susceptibility testing in our laboratory. This testing involves placing antibiotic-infused discs on a standardized inoculum of bacteria spread in a lawn onto a Mueller Hint... 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
