Macrophage Infected with Francisella tularensis Bacteria

Scanning electron micrograph of a murine macrophage infected with Francisella tularensis strain LVS. Macrophages were dry-fractured by touching the cell surface with cellophane tape after critical point drying to reveal intracellular bacteria. Bacteria (colorized in blue) are located either in t...

Micrococcus luteus line inoculation

Line inoculation of Micrococcus luteus on a TSA slant showing Filiform, uniform growth, along the margin. Culture was grown for 3 days at 37 degrees, M. luteus usually takes 3+ days for good growth. Read More

Bacillus subtilis

Streak plate isolation showing colonial morphology of Bacillus subtilis on trypticase soy agar (TSA) incubated for 24 hours at 37oC. Note the rough and dry/matte texture characteristic of this organism’s growth. Read More

Microbes in the Environment

Microbes are everywhere; they live in us and on us. They can't be seen with our naked eyes, thus we tent to neglect that they're there or even existed. Some microbes are harmful and some are not. However, we must learn to avoid contaminating sterile media and materials with these microbes. In th... Read More

Life under the Microscope: Stunning Photographs from the BioScapes Competition [Slide Show]

In the 1800s English poet William Blake famously challenged his readers to “see a world in a grain of sand.” If only he had owned a modern microscope. Thanks to increasingly powerful optical tools, we now know that beneath the skin of every leaf, inside each speck of dirt, and within our own blo... Read More

Blood agar/Hemolysis

Three organisms inoculated onto blood agar, straight line inoculation, to demonstrate hemolysis. From top to bottom:
Streptococcus pyogenes: beta, complete lysis of red blood cells, clear area around colony growth.
Streptococcus bovis: alpha, incomplete lysis of red blood cells, green area ... Read More

Unfertilized egg Ascaris

Female ascaris release unfertilized eggs which are elongated in shape. Eggs are always bile stained. Children are more susceptible towards ascaris infestation. It is one of the major public health problem in developing countries. Read More

Eye of Science - Scientific photography

Beautiful scanning electron microscopy images.

"For 2 decades we have been devoting our work to the visualization of the previously unknown and invisible. Detailed, aesthetic, and scientifically correct we present an access into the microscopic world of biology, medicine, chemistry, technolog... Read More

Summer Research, Undergraduate Students, Lab Themed Desserts, and Bdellovibrio!

In this blog post, I discuss our Summer Research Program's "Lab Themed Dessert" competion, for which one of my students created a cake "sculpture" of Bdellovibrio attacking and invading E. coli. It was tasty, informative, and fun! My student clearly thought about Bdellovibrio a LOT during the ... Read More

Thesis work on mycology for the degree of PG in Medical Microbiology.

My name is Sangeeta Khadka and i am from Nepal. I am a PG level student at St. Xavier's College. Recently, i have been doing my thesis work on mycology in Nobel Hospital and Research Centre for the degree of PG in Medical Microbiology.

This is a picture of different Candida species isolated ... Read More

Mannitol Salt Agar (MSA)

Mannitol Salt Agar (MSA)
•Important Ingredients: Phenol red, mannitol (sugar), 7.5% NaCl
•Differential: between pathogenic S. aureus and S. epidermidis
•Selective: NaCl inhibits non-halophilic organisms. Organism that can grow are halophilic.
•Mannitol Fermentors: fermentation of acid cau... Read More

How naked is naked? Scales of the Gymnamoeba (naked amoeba) show remarkable details!

In memory of Eugéne Penard (1855-1954) we have created a website to show the variety and beauty of amoeboid organisms in light- and electron-microscopic images. Read More

Streptococcus pyogenes Gram Stain

Gram stain done on S. pyogenes showing the characteristic long G+ streptococcus chains. Culture grown on blood agar for 48 hrs at 37 degree’s C. Read More

Lipid Agar

Lipid Plate/Tributyrin Agar used to test for an organisms ability to produce the exoenzyme lipase which breaks down the lipids in the agar creating a clear zone around the organism. (A) Serratia marcesens, lipid hydrolysis, indicated by a zone of clearing around the growing colony, as well as th... Read More

Who knew microbes could be so artistically inclined?

In the photo series "Impermanence," South Korean artist Seung-Hwan Oh creates colorful, otherworldly portraits with a little help from some "friends" — emulsion-consuming microbes, that is.

By immersing an exposed roll of medium-format positive film in water containing these bacteria and lea... Read More

What's this?

Hi everybody, I saw this in a plash near my house and there was a lot of them. Can somebody help me about the identification or send a link if you know some kind of protozoa base Read More

Fuzzy Frosty

This smiling Frosty is no ordinary snowman—he's made entirely of mold.

The living artwork is the creation of Stephanie Mounaud, an infectious disease researcher at the J. Craig Venter Institute (JCVI) in Rockville, Maryland.

For the last several Christmases, Mounaud has used the different ... Read More

Lyme Disease Bacteria, Borrelia burgdorferi

The Lyme disease spirochete, Borrelia burgdorferi, is an obligate parasite that cycles between ticks and vertebrate hosts. B. burgdorferi alters the proteins expressed on its outer surface, depending on the state of each host. Here, we used immunofluorescent antibodies to identify spirochetes th... Read More

Bacillus cereus Biofilm viewed under microscope

Bacillus cereus, a food-borne pathogen, is capable to form biofilms. Biofilms are microbial communities that are controlled by a biological mechanism called quorum sensing. In this image, the B. cereus biofilm was viewed under microscope using LPO and grown in microtiter plate well for 48 hrs of... Read More

Unknown Fungal Contaminant/MAC

Unknown fungal isolated contaminant found on MAC. MAC plate was incubated for 2 months at 4 degrees C once fungal growth was seen. This colony seemed to emerge from the agar and had a 3D appearance. The center of the colony had what seemed to be hyphal growth while the edges had a hard waxy un... Read More
