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

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
Mapping deletion mutations by genetic tools is one thing, seeing them displayed along the length of a DNA molecule is quite another. But how can one see what isn’t there? In 1968, Ronald Davis and Norman Davidson did just that—visualizing deletion mutations in the genome of coliphage l. They rea... Read More
Streak plate of Streptococcus pyogenes (incubated @ 37 degrees C for 48 hrs) showing beta hemolysis, complete lysis of red blood cells, around the isolated colonies. Image taken using transmitted light. Read More
A chemist at Washington University in St. Louis is studying siderophores, iron chelating molecules released by bacteria during an infection, with the thought of using them to design personalized antibiotic therapy that would avoid the rapid evolution of resistance that plagues antibiotic drug di...

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
Pictured here is Rhodotorula, a beautiful coral-colored yeast grown on Sabouraud's Dextrose Agar.
Rhodotorula species are common environmental contaminants, found naturally in air, water, soil, and other areas. This yeast rarely is a pathogen, though it can cause infections in immumocompromis... 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

Sputum specimen from sick of fibrosis cystic can hold many microbes and yeast. This specimen sent to our laboratory Mycobacteriology of Polyclinic University of Messina for mycobacteria research, shows yeast cells with Ziehl-Neelsen stain. Read More
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
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
Another major goal of synthetic biology is to engineer unnatural molecules and compounds into systems and tools that mimic those found in biology. For instance, Joanna Aizenberg and her laboratory have pioneered using self-assembling synthetic nanofibers to generate capture-and-release devices t... Read More

For anyone interested in Antibiotic Awareness Week, a big part of the story is that patients (or their parents) demand antibacterials even for viral infections. And doctors often comply, just to get rid of them (the patients, that is). This high-resolution PDF can be printed out for waiting ro... Read More
